Exposure to artificial light, especially television light, was associated with becoming overweight or even obese.

Experts say you should avoid watching TV at night and keep your room dark.

"Really try to reduce or minimize the time that you are spending on electronic devices, on watching TV, making sure that the bedroom is dark when you're sleeping. So environmentally, just doing all you can to minimize that artificial light exposure at night," said Dr. Reena Mehra, with Cleveland Clinic.

Previous research shows getting less sleep and having prolonged onset of sleep were also related to weight gain and obesity.
