New research shows that dozing off to late-night TV or using a night light to make you feel safe at night might actually be causing you to gain weight.
The study analyzed the sleeping habits of nearly 44,000 women in the United States and found those who say they sleep with a TV or a light on in the room gained 11 pounds or more and had a body mass increase of about 10 percent over a five-year period.
There was also a 22 percent chance of becoming overweight and a 33 percent chance of becoming obese or having too much body fat.
Researchers believe artificial light at night can throw off your body clock and might be mixing up your metabolism, causing you to gain weight.
To kick the habit and cut the lights, health officials recommend taking TVs and other tech devices out of your bedroom in order to support a healthy sleeping environment.
The study can be found in the Journal of the American Medical Association.
What you think of the study? Do you sleep with the television on and do you think there could be a link between night light and weight gain?
