Scientists have badociated sleep with artificial light and the risk of gaining weight or developing obesity in women.
Researchers at the US National Institute of Health in the United States have discovered a connection between any exposure to artificial light (such as a TV or a light lit in the room) at night during sleep and weight gain in women.
The research, published online June 10 in JAMA Internal Medicine, is the first to find an badociation between all nighttime artificial light exposure during sleep and weight gain in women.
The research team used data from a questionnaire of 43,722 women from the Sister study. The participants, aged 35 to 74, were not posted workers, did not sleep the day or were not pregnant at the beginning of the study. The study questionnaire asked if women slept without light, with a small night light, an outside light, or a light or television in the room.
Although results vary with the level of artificial light at night, researchers found that women who sleep with a light or on television are 17% more likely to have gained about 5 kg (11 pounds) or more .
The use of a small nightlight was not badociated with weight gain, and the badociation to a light coming from outside the room was modest.
The results suggest that cutting off lights at bedtime could reduce a woman's chances of becoming obese. – The Palm Beach Post, Florida / Tribune News Service
