Blue Light and Bedtime: A Bad Combination


Getting enough sleep is essential to staying healthy. The body needs to rest and recharge, but because of work schedules, stress, and other factors, many people do not get enough sleep each night. Part of the reason is technology. The blue light on laptops, smartphones, and tablets signals the brain that it's time to be awake. The brain regulates sleep by producing melatonin, but the blue light of screens says to the mind, "This is awake time" Shutting down phones and other tech devices before bed is key to getting better rest.

In the brain, glial cells are the housekeepers. They clean up all the mental debris and cellular waste during sleep, but if the body isn't at rest enough of the time, the result is fatigue, mental fog, and lower productivity. New research even links the use of screens before bed to higher BMI. Eating well and maintaining a healthy diet is essential, but don't wreck all those healthy habits with too much blue light at bedtime. Park the tech in another room and get the rest your body needs.
