Dear MEL Topic Readers,
Sleeping with even a small amount of light may harm your health, study says
Yes, most of you can probably sleep with some or a little light on. You may think closed eyelids block a dim light. But in fact, even if your eyes are tightly closed, a dim light still enters the eyelids and disrupts your sleep, according to a study conducted on 20 healthy young adults. The researchers found that even very little light disrupted the slow-wave and rapid eye movement sleep, more known as REM sleep, where most cellular renewal occurs. Also found were higher heart rate and insulin resistance, and unbalanced nervous systems, which could cause higher blood pressure. So, if you want to have a goodnight’s sleep and a sharper brain the next morning, make sure to turn all the lights off and never look at your mobile phone before going to bed. If you still need some light for safety reasons, choose reddish or brownish colors, but not blue.
