Sleep


Research: Exercise will not worsen sleep

Evening exercise does not appear to disrupt sleep or alter energy intake.

Just about anyone who has trouble sleeping has filled out a sleep hygiene questionnaire and received education to avoid exercise within 4 hours of bedtime because it will disrupt sleep and make you hungrier.  In today’s culture, following this advice makes evening exercise nearly impossible.  If you are like me, you are lucky to be home by 5:30 p.m.  

 


Research: Turn out the lights and lose weight

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.
