(LONDON) -- Here's a weight reduction tip most people probably aren't aware of: the darker the bedroom, the better the chance of shedding pounds.
As peculiar as it sounds, too much light exposure during sleep time seems to increase the risk of obesity. That's according to the Breakthrough Generations Study of more than 113,000 women.
When all other personal habits were taken into consideration, the researchers discovered that the odds of women becoming obese were greater when in bedrooms where more light came through.
Although the exact link hasn't been established yet, study researcher Anthony Swerdlow from the Institute of Cancer Research in London says, "Metabolism is affected by cyclical rhythms within the body that relate to sleeping, waking and light exposure."
In other words, light appears to disrupt the production of the sleep hormone melatonin, which, in turn, affects mood and alters the way the body processes food.
Previous research has also revealed that people who sleep fewer hours also eat more calorie-packed food than others who get more shuteye.
