Working on weight loss? Turn off the lights!



Sleeping With Lights On May Increase Risk For Obesity In Women, Study Suggests


Recent research shows that sleeping with the lights on not only adds to your electricity bill, but also adds extra pounds to your weight. According to a study published in JAMA Internal Medicine involving 43,722 female participants, exposure to artificial light is correlated with weight gain and obesity.


Obesity, one of the most prevalent medical conditions in the United States, is defined as a person having excess weight or a higher than normal body mass index (BMI).

The study obtained data that substantiated this correlation and stated that in the span of six years, having the lights on at night led to an increase of 11 pounds in weight, an increase in 10% or more of BMI, and a 22% increased risk of being overweight. It is important to note that the variables of the study were not controlled and this correlation does not imply causation; however, people should cut off the lights at bedtime to reduce any potential risk it can have in disrupting any light sensitive regulation that occurs in the body.


An outstanding number of 1.9 billion people have obesity worldwide. Obesity can cause a wide range of illnesses, such as heart disease, diabetes, kidney problems, and joint disorders. To avoid the domino effect that could further disrupt your health, it is vital to be cognizant of the fact that obesity is a treatable disease! Obesity can be overcome through lifestyle changes including avoiding processed foods, decreasing carbs, intermittent fasting and exercise.  Quality sleep is also a known factor in helping women lose weight.  This can’t be stressed enough, sleep well so that your body is getting the rest it needs to keep appetite-regulating hormones, such as ghrelin and leptin in check, and to hold your weight at a stable, healthy level.
