Darkness prior and during sleep may reduce weight gain

Light has long been known as the enemy of good sleep.  From the standard night light to the relatively new blue light sources created by our electronic lifestyles, we have been bombarding our eyes with light that inhibits our ability to get a good night sleep.  Most of us wish we could get a good night sleep with the peace like that of a small child or baby.  The light increases cortisol and suppresses melatonin levels.  Melatonin is natures signal to sleep, and without proper levels, you will not sleep well.  Exposure to light and in particular blue light at night doesn’t just interrupt your chances of a great night’s sleep, but it may also increase your risk of in weight gain and inhibit weight loss.
