If women leave a television or a room light on when we sleep, we will gain weight, a lot of it, even when diet and physical activity are taken into account.
The light keeps melatonin from being produced, resulting in changes in our circadian rhythm and eating patterns. The light may cause chronic stress and interfere with the release of hormones that play a role in feeling hungry or metabolism, in general.
The results of this study add to growing evidence that it’s best to sleep in a dark room.
In the morning, sunlight penetrates your eyelids and cranks up the pineal gland in the brain that wakes you up.
Perhaps when there is a light on in your room, you may not be fully going to sleep which could keep your memories from being filed in the right places or even allow the brain’s debris to get washed away.
Turn off the light and go to sleep!
