Before you crawl into bed tonight, turn out the lights and power down your devices. Exposure to artificial light — from sources such as overhead lights, smartphones and televisions — was associated with higher rates of obesity, according to new research published in JAMA Internal Medicine.
The study included almost 44,000 women between the ages of 35–74 over a six-year period and found women who were exposed to artificial light while sleeping had a 17% higher risk of gaining approximately 11 pounds compared to those who slept in the dark; their rates of obesity were 33% higher. Women who fell asleep with a television or light on were also more apt to gain weight and become overweight or obese over time.
LIGHT AND CIRCADIAN RHYTHM
“Humans are genetically adapted to be active during daylight and sleep in darkness at night,” explains lead author Dr. Yong-Moon (“Mark”) Park, MD, postdoctoral fellow at the National Institutes of Health. “Exposure to light at night while sleeping could alter the body’s 24-hour body clock leading to changes in hormones and other biological processes that regulate sleep, appetite and weight gain.”
While the study focused on exposure to artificial light in the bedroom but Park notes that light coming from outside the room — from other rooms or street lights, for example — was also associated with a slightly increased risk of weight gain. The study did not explore whether overall exposure to artificial light, including daytime exposures, had an impact on weight.
Several studies have linked sleep issues, including insomnia, sleep duration and sleep disruptions, to higher rates of obesity. Research published in the journal Sleep Medicine found the incidence of obesity was higher among those who slept fewer than six hours or more than nine hours per night; chronic insomnia was also associated with higher BMI, according to one study.
The link between sleep and obesity is one reason to make improving sleep a priority, says Lu Qi, MD, PhD, director of the Tulane University Obesity Research Center. But sleep is just one of the known risk factors for obesity. Lifestyle factors such as an unhealthy diet, sedentary lifestyle, stress and smoking are also linked to an increased likelihood of being overweight or obese.
“Even if you improve your sleep habits, you still need to pay attention to other risk factors,” says Qi. “We also need to be cautious in interpreting these results; artificial light might be a factor but it could be correlated to other habits that were not part of this study.”
Park agrees, adding, “While our study provides stronger evidence than other previous studies it is still not conclusive. Even so, it seems reasonable to advise people not to sleep with lights on. Turning off the lights at bedtime may be a simple thing we can do to reduce the chances of gaining weight.”

Did you know?
Increased cortisol may cause insomnia, hyperactivity and decreased thyroid function and poor memory
Low dopamine may result in poor focus, low libido, and depression with exhaustion
High glutamate may contribute to anxiety, sleeplessness and irritability
Lower serotonin levels may lead to depression, anxiety and insomnia
Epinephrine and norepinephrine may increase anxiety, hyperactivity, insomnia and insulin resistance
Low GABA may lead to increased anxiety, insomnia and irritability.
How does imbalance occur?
Many factors contribute to disruption in our delicate system balance. Poor diet, stress, environmental factors, lack of or too much exercise and sleep, stimulants, genetics, even medications can deplete and offset the harmony.
How do you fix this?
Take home lab kits from Sanesco and Precision Analytical are now availablefor neurotransmitter and hormone analysis. The tests collect the urine breakdown products of serotonin, dopamine, GABA, epinephrine, norepinephrine, glutamate, melatonin, cortisol, estrogens, progesterone, androgens and more. The kit is shipped and the lab company runs the tests and provides the results back to the doctor. Nutritional analysis through lab drawn blood work is also available to evaluate vitamin and mineral status. Laboratory results will guide clinical decisions with clarity and focus.
Dr. Laura M. Brown, ND can help evaluate where to start, access the tests kits and provide blood requisitions for you and subsequently interpret the results. Individualized protocols are the heart of naturopathic medicine. Diet and lifestyle adjustments are first and foremost, then where needed, vitamins, minerals, and nutraceuticals may be added to help balance the body and get you back to feeling yourself.
You’re lying in bed, trying to decide what time to set your alarm for tomorrow. You could get a full seven hours of sleep if you wake up at your normal time, or you could wake up an hour and a half earlier to make that morning spin class. Which should you choose?
“Sleep and exercise are both incredibly important for your body, but if you have to choose one it has to be sleep,” says Amy Leigh Mercree, a wellness coach. “Adequate amounts of sleep gets your body the time it needs to replenish and refresh your cellular functioning. If you do not get to do that, your health will suffer greatly.”
But just because sleep is usually the answer doesn’t mean you should discount the need for exercise for your overall health if you’re always crunched for time. “Exercise changes the brain and is critical for brain health. What’s good for your body is good for your brain, too,” said John Assaraf, brain researcher and CEO of NeuroGym. “Through exercise, you are feeding your brain by increasing blood and oxygen flow.”
When you have to choose, remember a short workout is better than no workout at all. If you have only 10 minutes, do a quick workout at home with simple exercises like squats, jumping jacks and planks. There are also lots of apps that can give you a quick workout for a specific time frame using only your bodyweight.
BE HONEST WITH YOURSELF
If you find yourself constantly short on time, it might also be good to see where that time is actually going. Try tracking your days meticulously for a week to see where you might be wasting time. Almost everyone is guilty of too much time on social media or watching TV, so see if you could substitute that time for working out. This will help you get a proper night’s sleep and a workout.
1. Make your bedroom your oasis. If you are going to invest in something, why not invest in a good mattress and pillow that you will spend almost a 1/3 of your life on. Complete your bed with comfy blankets and sheets.
2. Keep it dark. Shut off all alarm clocks, TV’s, phones etc. Make sure no LED light is being emitted. This may require you to unplug some electronics around your room. Black-out curtains are a must.
3. Control room temperature. Make sure you are not too hot or too cold. There is nothing worse than sweating all night under the covers while your body struggles to maintain optimal body temperature.
4. Stop consuming caffeine after 2pm. This ensures that the effects of caffeine will be long gone before your head hits the pillow. Try a decaf coffee in the afternoon to fight off cravings.
5. Don’t work out within 2 hours before bed. This will disrupt hormone rhythms and deprive your body of energy stores needed to repair your body as you sleep.
6. Meditate. A simple 5-10 minutes mediation or deep breathing routine will calm the nervous system and transition you from our fight-or-flight response to your rest-and-digest state.
7. Reduce exposure to blue light after the sun goes down. Change display settings on your phone or use computer programs to block out blue light at night.
8. Have a chamomile tea or small snack with raw-honey to maintain your blood sugar levels throughout the night.
You may already suspect your metabolism slows as you age. According to research published in the Public Health Nutrition journal, you’re right. In a review of data on energy expenditure, researchers found simply getting older is associated with progressive declines in basal metabolic rate. On top of that, there are many daily habits that can drain your metabolism even further.
But you don’t have to go down without a fight. Cut out the below habits and watch your metabolism and energy levels improve.
Eating a nutritious breakfast is always a good way to start your morning. Because your metabolism slows down during sleep, eating can fire it up and help you burn more calories throughout the day. According to Rush University Medical Center, “When you eat breakfast, you’re telling your body that there are plenty of calories to be had for the day. When you skip breakfast, the message your body gets is that it needs to conserve rather than burn any incoming calories.”
OK, so it’s about more than just eating something in the morning. If you grab a sugary donut or eat a muffin in the car, you’re setting yourself up to crash later. Instead, choose something with filling protein and fiber like eggs, yogurt and berries or whole-wheat toast topped with peanut butter.
Going from your office chair to your car to your couch can lead to a very sedentary routine. And sitting for extended periods puts your body into energy-conservation mode, which means your metabolism can suffer. According to the UK’s National Health Service, “Sitting for long periods is thought to slow metabolism, which affects the body’s ability to regulate blood sugar, blood pressure and break down body fat.”
Cardio is great, and it can quickly burn calories, but once you’re done running or cycling, your calorie burn quickly returns to normal. When you do HIIT and resistance-based workouts, however, your calorie burn stays elevated for longer as your muscles repair themselves. Per the American Council on Exercise (ACE): “Strength training is a key component of metabolism because it is directly linked to muscle mass. The more active muscle tissue you have, the higher your metabolic rate.” And, according to ACE, a pound of muscle burns an additional 4–6 calories each day compared to a pound of fat.
Protein feeds your muscles, promotes satiety and is an important component to sustaining a healthy weight. Eat too little, and you may have trouble building or maintaining muscle mass — and per the above, we know muscle’s importance to metabolism. Also, protein requires more energy to break down than carbs or fat, so you’ll actually burn more calories during digestion.
One bad night’s sleep is enough to leave you feeling sluggish and impair your cognitive processing. String together several nights in a row — or a lifetime of inadequate sleep — and science shows decreased metabolism and hormonal imbalances may follow.
In a study published in The Journal of Clinical Endocrinology & Metabolism, researchers found drinking 500 milliliters of water (about 2 cups) increases metabolic rate by 30%, and that spike lasts for more than an hour. So, drink water throughout the day to stay hydrated, and you’ll get the added benefit of a boosted metabolism.
When stress levels increase, your body produces a hormone called cortisol. Cortisol leads to increased appetite, makes us crave comfort foods, decreases our desire to exercise and reduces sleep quality — all things that negatively impact metabolism. So, while you can’t always control your stress levels, managing stress can go a long way toward protecting your body’s internal fire.
Falling on ice can leave you red-faced with embarrassment, or far more seriously, hurt badly from taking a knee to the ice or falling awkwardly on icy snow. Slippery sidewalks, driveways and icy parking lots can be risk factors for falls in winter. Avoid a bad fall with these top tips!
Walk like a penguin
The penguin waddle helps you keep a center of gravity over the front leg as you step, instead of split between the legs. Short strides also help keep your center of gravity, which help avoid falls. When walking, extend your arms out from your sides to increase your centre of gravity. Don’t keep your hands in your pockets! Walk slowly, with short strides and try to land your steps with a flat foot.
Keep walkways clear
Shovel snow and scrape ice as soon as possible. Liberally sprinkle ice melt product or sand onto walkways to provide foot traction and to make sure surfaces don’t turn to ice. This not only protects you and your family, but also postal carriers and others when they’re walking around your property. Where possible install or use handrails for extra support.
Take all precautions
Be extra cautious walking after a storm. Tap your foot on potentially icy areas to see if it is slippery. Hold a railing while walking on icy steps. Stay steady by wearing proper winter footwear. Lightweight boots with a thick, non-slip tread sole will provide good traction on ice. If a sidewalk is icy down the middle, walk on the snow beside it to avoid slips.
Lighten your load
Carry fewer bags on snow days, since excess baggage can throw off your balance and make it tougher to regain your balance once you lose it. Keep your hands free by putting away your phone while walking – you may need to catch yourself!
Boost balance with exercise
You can’t control the weather, but you can improve your balance through regular exercise. Exercise is an ideal way to help you stay safely on your feet because it helps improve balance, flexibility and strength. Talk to a chiropractor about ways to improve your balance and strength in order to prevent falls.
Visit your chiropractor
Don’t let a fall get you down. If you do take a tumble, visit your chiropractor. They’ll get you back to doing the things you love to do and will work with the rest of your care team to help prevent future falls.
You try to eat well to feel good and stay healthy. While it’s optimal to get your nutritional needs from the foods you eat, it’s not always possible. There is conflicting information out there on the benefits of supplements, but the Dietary Guidelines for Americans 2015-20201 say that supplements may be useful for providing the nutrients you may be lacking from diet alone.
Still on the fence? Consider these top five reasons to add a multivitamin to your daily regimen.
Healthy aging. As we get older, our bodies have a harder time absorbing nutrients from food. The National Institute on Aging notes that starting around age 50, people begin to require increased amounts of certain vitamins and minerals.1 In fact, according to a study published in the June 2009 issue of the American Journal of Clinical Nutrition, researchers found that taking a daily multivitamin & mineral supplement may help improve micronutrient deficiencies associated with aging.3
Making up for eliminated food groups. While some people have to cut certain foods like nuts or gluten out of their diets due to allergies, many eliminate particular foods or food groups from their diet voluntarily. This can cause vitamin deficiencies that would be helped with a multivitamin.
Trying a paleo diet? You might risk a shortage of calcium or vitamin D by eliminating dairy or grains. Cutting back on red meat? A multivitamin will replace the iron and B12 you would normally get from diet.†
Getting the RDAs you’re not getting from food.You’ve probably heard that the typical Western diet doesn’t include nearly enough daily fruits and vegetables. As part of that, you don’t always get the vitamins those natural foods supply. Supplementing with a multivitamin containing phytonutrients from fruit- and vegetable-derived ingredients may help. In addition, it’s important to keep in mind that RDA levels are set to prevent nutrient deficiencies. But there’s a wide range between taking enough vitamin C to avoid scurvy and the optimal amount you can benefit from.†
Getting that extra energy to get through the day. In today’s “go-go-go” society, one of the top complaints is a general lack of energy. Instead of reaching for that third cup of coffee, remember that your cells require certain vitamins and minerals to power your busy life; especially if you’re not getting a full eight hours of sleep or eating a balanced diet, a multivitamin can help provide the nutrients you need to feel energetic throughout the day.4
Managing stress. Daily life stressing you out? You’re not alone. But vitamins and micronutrients play a significant biochemical role in improving your brain’s cognitive processes, and studies have shown that a daily multivitamin—particularly one with high doses of B vitamins—can help to reduce stress and support a healthy mood.5†
Ready to add a daily multivitamin to your diet? Be sure to check with your healthcare practitioner to see if he or she has a recommendation and to ensure that any medications you’re currently on won’t interfere with their effectiveness.
Many women notice after age 45 that fat seems to accumulate readily at the waist. There are even terms for it, like menopause belly, muffin top, or “meno-pot.” What does the science tell us about menopausal belly fat and how to get rid of it? What are the hormonal drivers and are they amenable to change with personalized lifestyle medicine? Certainly belly fat, specifically subcutaneous and visceral abdominal fat, increases during menopause,1-3 when the changing hormonal environment can bring with it a remodeling of fat storage patterns. Abdominal fat, especially visceral fat, is biochemically different and more metabolically active than fat stored in other areas, secreting more pro-inflammatory cytokines and adipokines.4 That means preventing or reversing belly fat is not just a vanity project, it’s a meaningful step in managing a woman’s overall health, as abdominal fat has been consistently linked with insulin resistance, impaired glucose control, and overall higher cardiometabolic and breast cancer risk. Practitioners are often asked ‘How can I get rid of menopausal belly fat?’, and it is important to remember that effective management is multifaceted – encompassing an understanding how changes in sex steroids interact with other endocrine systems and also with lifestyle choices, and recognizing the best time to implement a lifestyle medicine approach is in the years before a woman’s final menstrual period.
The changing hormonal environment
A robust understanding of the hormonal changes associated with perimenopause and menopause can guide women toward effective intervention. Here are the top five hormonal changes associated with the menopausal transition.
Changes in estrogen and estrogen dominance: Menopause is often framed simply as the loss of estrogen, but the road from pre- to post-menopausal estrogen levels is not necessarily smooth. Although loss of estrogen itself is linked with increasing abdominal fat,2,3 paradoxically the estrogen dominance that occurs in perimenopause and that may continue into menopause is seen clinically as a culprit in expanding abdominal fat mass.5 Between age 35 and 45, most women are beginning to run low on ripe eggs and experience hormonal changes linked with advancing reproductive age.6 During this time reduced progesterone coupled with high and erratic estrogen occurs.6,7 Estrogen declines but is in relative excess to progesterone. This is the definition of estrogen dominance: having a progesterone level that’s less than 100X the level of estrogen, creating an imbalance in the estrogen-progesterone partnership and essentially an inadequate level of progesterone to keep estrogen in check. Local estrogen production in adipose tissue can also contribute to estrogen dominance during this time. For example, aromatase enzymes, responsible for converting androgens to estrogens, are more active in visceral adipose tissue of post-menopausal women in response to cortisol.8
Cortisol: Dysregulation of the HPA axis and cortisol excess can manifest as increased central and visceral fat mass and metabolic disturbances such as insulin resistance.9,10 Increased production of cortisol,11 and conversion of cortisone (inactive) to cortisol (active) has been described in post-menopausal women,12 indicating that increased cortisol synthesis and conversion could contribute to metabolic dysfunction in these women. Cortisol is regulated in part by sex steroids, and estrogen down-regulates the expression and activity 11β-HSD1, the enzyme involved in converting inactive cortisone to active cortisol13 – so higher estrogen, lower 11β-HSD1 and less active cortisol formed. Declining estrogen levels during menopause can have a knock-on effect on cortisol formation, and 11β-HSD1 has been shown to be upregulated particularly in visceral fat in post-menopausal compared with pre-menopausal women. 1,11,12 As well as contributing directly metabolic dysfunction, higher cortisol can feed back to hormonal environment and contribute to estrogen dominance occurring at this time through cortisol-induced aromatase activity.8,14
Insulin: Fat cells accumulating in the abdomen is linked with insulin resistance. The pro-inflammatory cytokines produced by abdominal fat interferes with insulin signaling.15 This results in insulin resistance where cell response to insulin is lost, which creates a cycle where greater production of insulin is required to manage blood glucose levels. Insulin is a gatekeeper of metabolism, and rising insulin levels can set off a chain reaction that ultimately leads to a cycle of weight and abdominal fat gain. Insulin can lower production of sex hormone binding globulin (SHBG) in the liver.16,17 Lower SHBG results in greater free androgens and estrogens in circulation, and is linked with visceral fat and insulin resistance in menopausal women.18,19 In addition, insulin resistance can have a knock-on effect on leptin, insulin’s cousin.
Leptin: Leptin is the put-down-your-fork hormone, the one that tells you when you are full.20 Elevated insulin levels eventually lead to elevated leptin, which despite what you may think, does not mean you are more likely to put down your fork and stop eating. Instead, consistently elevated leptin levels lead to a dysfunction of leptin receptors and they stop sending signals to the brain to tell you to stop eating – this is called leptin resistance.21 The mechanisms driving leptin-resistance are complex, but high intakes of refined carbohydrates have linked with its development.22
Thyroid hormones: Thyroid hormones, which regulate how quickly we burn calories and maintains our metabolism, can becomes unbalanced with age, a trend that has been labeled ‘thyropause’. If the thyroid becomes underactive, this can lead to symptoms including weakness, fatigue, and weight gain.23
What can be done?
One of the biggest myths in women’s health is that once hormones change with menopause, abdominal adiposity is immovable – however addressing modifiable hormones such as cortisol and insulin in the following ways can have an impact.
Make foundational changes to dietary intake. When evaluating diet, consider factors that influence insulin levels, such as high carbohydrate intakes or intake of refined carbohydrates which require greater insulin response to manage spikes in plasma glucose. Remove inflammatory or trigger foods, as inflammation can contribute to insulin resistance.31 Add in foods rich in antioxidants which promote detoxification. Eliminate alcohol which robs you of deep sleep and lowers metabolism by more than 70% for 24 hours. Choosing when to eat during the day can also make a positive impact to insulin levels and insulin sensitivity. Time-restricted feeding (TRF) protocols, a type of intermittent fasting, where food is consumed during a limited number of hours per day (often 6 or 8) has been shown to reduce body weight and abdominal fat32 and improve insulin sensitivity even without weight loss.33
Add more movement to the day. Sitting is like the new smoking. Approximately 35 chronic diseases and conditions are associated with sedentariness, and sedentary behavior makes people more prone to gain body fat.24High intensity interval training (HIIT) is effective at reducing abdominal and visceral adiposity, as well as improving insulin sensitivity and building muscle.25,26 Studies in post-menopausal women show that HIIT training results in greater abdominal and visceral fat mass loss compared to continuous exercise programs (where heart rate was maintained at a constant level)27,28 showing that HIIT is a time-efficient strategy for improving central obesity in this population. In addition to HIIT programs, practicing yoga can be recommended for menopausal women, showing significant reductions in menopausal symptoms.29 In broader populations, interventions that included yoga asanas were associated with reduced evening and waking cortisol levels, as well as improved metabolic symptoms.30
Support reparative sleep. A primary step to losing belly fat is to get enough sleep and to make it quality sleep. Epidemiological studies have repeatedly shown links between sleep duration and the risk of obesity and central adiposity.34 People sleeping 7-8 hours/night night have been shown to accumulate less visceral fat mass than those sleeping for ≤6 hours/night.35 Sleep debt leads to changes in leptin and other hormones related to satiety, greater feelings of hunger, dietary indiscretion and poor food choices, as well as reduced physical activity and insulin resistance.34 In other words, getting that solid sleep needs to be a priority. As well as sleep quantity, sleep quality has to be considered, as poorer sleep quality is associated with higher visceral fat mass.36 Subjective poor sleep quality is linked with altered cortisol response37 and insulin resistance in postmenopausal women.38

It’s the most wonderful time of the year, but for those following a diet, the holidays may stir up stress and anxiety around food. The ketogenic diet is not the most “social” diet, but there are ways to stick to it, even in the most daunting of times, such as holiday celebrations.
If you can’t eat keto, at least aim for low-carb
Your holiday party may not be stocked full of keto-friendly foods, but there is a high probability that you can nibble on some low-carb options. The cheese platter is, more often than not, a pretty safe bet for cheese (of course!), but also for other low-carb foods such as nuts and meats. Just stay clear of candy-coated nuts, dried fruits, and cured meats you suspect may have added sugar!
Another low-carb holiday party go-to is the veggie platter. Lucky for you, this usually gets the least attention by guests, thereby giving you full access to it. Stick to the low-carb vegetables options such as broccoli, cauliflower, celery, and cucumber. If your event is serving dinner, opt for the meats or any salads (without sugar-loaded dressings), and low-carb vegetables. Things to stay away from are the mashed potatoes, any bread/pastry-like foods, sauces, and, of course, the sweets. Sticking with low-carb as opposed to ditching the diet completely will make transitioning back into ketosis much easier.
Prepare for success and give yourself options
If you are uncomfortable not knowing what food options will be available at your holiday gathering, prepare some food in advance. Better yet, prepare a keto-friendly dish to share with everyone! Take a high-fat dip to pair with that veggie platter and a salad dressing you can pour on any dry salads to avoid sugary dressings. You can also pack some snacks such as high-fat nuts (e.g. macadamia nuts) to graze on throughout the evening. Additionally, medium-chain triglyceride (MCT) oil is a great tool for ketogenic living. Fill a small jar with MCT oil to take with you and use on any dish or in beverages. MCTs are highly ketogenic and have even been shown to increase ketone production without carbohydrate restriction.1
The popularity of the ketogenic diet has made it simple to find recipes that anyone can enjoy. Consider making a ketogenic dessert to bring and share so you can “indulge” too, while also preventing you from caving into the temptations of sugar-laden treats.
Stay positive and remember your “why”
It can be difficult to gain the support of those around you when your dietary choices are perceived as something as radical as a ketogenic diet may seem to some. You may even be tempted to ditch the diet for the sake of your peers or those family members who just won’t back down from having you try “just one bite.” Be prepared to explain to others what the ketogenic diet is and why you follow it. Remember that there is no one-size-fits-all diet, and it is perfectly fine to have different views from others. Just stay true to yourself, remember your “why,” and stay positive, because there is nothing worse than engaging in a debate over food choices!
Tips for alcohol
Alcohol isn’t generally conducive to living a ketogenic lifestyle, and if you have no problem abstaining from it completely, that is your best option. If having a drink in your hand makes you feel more comfortable in a crowd, take club soda and sliced lemon with you; this will help you feel less segregated. With all this said, celebrations may be times when you can make exceptions (within reason). There are ways to enjoy a drink or two and stick to your goals; you just have to know what to look out for. For wines, opt for the driest you can find, white or red, and avoid sweet wines such as rosé. Most liquors are acceptable on their own or enjoyed with club soda or sugar-free beverages. Beers typically contain more carbohydrates, and they should probably be limited to one. If nutrition labels are available, check to see what the lowest-carbohydrate beer options are. Coolers and ciders are to be avoided due to their high sugar content.
Be kind to yourself and don’t overthink it
If you take into consideration all of the recommendations above, there is no reason to be stressed or anxious about your diet as you enter into the holidays. You are following a ketogenic diet to improve your health, right? Well, being kind to yourself is part of healthy living, and sometimes that means accepting that your diet can’t always be perfect. Also, keep in mind that you can always jump right back into the swing of things; a few days of indulging does not mean you have “failed.” There is more to health than simply what you put in your mouth, so do the best you can, be prepared, but most importantly, don’t get down on yourself if things don’t go as planned. Instead of focusing on your food options, focus on enjoying your time with loved ones over this holiday season.
As we said, the holidays are the most wonderful time of the year, and your diet shouldn’t change that for you.
Knowing you’re in love feels different for everyone. Some have been in love often and know the feeling well, and others may be not so sure if it’s love or just a deep infatuation.
Luckily, your body has some pretty sneaky ways of tipping you off to whether these feelings for your partner are more than just a passing phase. Keep an eye out for these tell-tale signs the next time you catch yourself wondering if you’re actually in love.
You can’t stop staring at them.
If your partner has ever caught you staring at them lovingly, it could be a sign that you’re head over heels. Eye contact means that you’re fixated on something, so if you find that your eyes are fixed on your partner, you may just be falling in love.
Studies have also found that couples who lock eyes report feeling a stronger romantic connection than those who don’t. It goes the other way too: when a study had strangers lock eyes for minutes at a time, they reported romantic feeling towards each other.
You feel like you’re high.
It’s completely normal to feel out of your mind when falling for someone.
A study from the Kinsey Institute found that the brain of a person falling in love looks the same as the brain of a person who has taken cocaine. You can thank dopamine, which is released in both instances, for that feeling.
This is a good explanation for why people in new relationships can act absolutely nonsensically.
You always think about them.
If you love someone, you may feel like you can’t get them off of your mind. That’s because your brain releases phenylethylamine, aka the “love drug” when you fall in love with someone. This hormone creates the feeling of infatuation with your partner.
You may be familiar with the feeling because phenylethylamine is also found in chocolate, which may explain why you can’t stop after just one square.
You want them to be happy.
Love is an equal partnership, but you’ll find someone’s happiness becomes really important to you when you’re falling for them.
So-called “compassionate love” can be one of the biggest signs of a healthy relationship, according to research. This means that you’re willing to go out of your way to make your partner’s life easier and happier.
If you find yourself going out of your way to keep your partner dry when walking in the rain or making them breakfast on a busy weekday morning, it’s a sign you’ve got it bad.
You’ve been stressed lately.
Although love is often associated with warm and fuzzy feelings, it can also be a huge source of stress. Being in love often causes your brain to release the stress hormone cortisol, which can lead you to feel the heat.
So if you’ve noticed your patience is being tested a little more than normal or you’re kind of freaking out, you may not need to carry a stress ball just yet; you may just be in love.
You don’t feel pain as strongly.
Falling for someone might be painful, but if you’ve noticed that literally falling doesn’t bother you as much anymore, it could be a big sign you’re in love.
A study conducted by the Stanford University School of Medicine had participants stare at a photo of someone they loved and found that act could reduce moderate pain by up to 40%, and reduced severe pain by up to 15%.
So if you’re getting a tattoo, you may want to keep a photo of your partner handy. Just in case.
You’re trying new things.
Everyone wants to impress their date in the beginning of their relationships, but if you find yourself consistently trying new things that your partner enjoys, you may have been bitten by the love bug.
In fact, a study found that people who have claimed to be in love often had varied interest and personality traits after those relationships. So even if you hate that square-dancing class you’re going to with your partner, it could have a positive effect on your personality.
Your heart rate synchronizes with theirs.
Your heart may skip a beat when you think about the one you love, but a study showed that you may also be beating in time with each other. A study conducted by the University of California, Davis, suggests that couples’ hearts begin to beat at the same rate when they fall in love.
Although you may not be able to tell if this has happened without a few stethoscopes, feeling a deep connection to your partner is a good a sign as any that you’re in love.
You’re OK with the gross stuff.
If you’re a notorious germaphobe and totally cool kissing your partner after just watching them pick their nose, you might just be in love. In fact, a study by the University of Groningen in the Netherlands found that feelings of sexual arousal can override feelings of being grossed out.
So that means if you’re super attracted to your partner, you may just let them double dip. That’s love, baby.
You get sweatier.
If you’re nauseous and sweaty, you either have a bad stomach bug or are falling in love. A study found that falling in love can cause you to feel sick and display physical symptoms similar to that of anxiety or stress, like sweat.
Although this feeling will probably pass once you really get comfortable with your partner, it may be a good idea to carry around an extra hanky, just to be safe.
You love their quirks
If you really get to know a person, chances are you’ll pick on the little things that make them uniquely them. And if you’re in love with them, these are probably some of the things that attract you most about them.
A study found that small quirks can actually make a person fall deeper in love with someone rather than just physical attributes because people have unique preferences. So although you may have judged your partner a little harshly on first glance, if you find that you’re suddenly in awe of their uniqueness, you might be in love.
