Exposure to light at night — from the glare of a bedroom TV or a street light through a window — may do more than disrupt sleep; it may increase the risk of weight gain and obesity , a new study suggests.

When you nod off is generally dictated by your circadian rhythm, your body's natural, built-in sleep clock. Biologically, humans are wired to fall asleep when it gets dark outside, and then wake at dawn.
However, it's not that simple - since we decided to invent lamps, TVs and then work jobs that involve night shifts.
All of these pump artificial light into your eyes which make the prospect of deep sleep a difficult idea. New research suggests artificial light could potentially increase the risk of weight gain.
Previous research found that it takes 60% longer to get to sleep if you've used an electronic device in the hour or so before sleep.
