Each Wednesday in July we will feature a Wellness Wednesday tip! Feel better, sleep better, look better!
Screen time at night keeps adults from falling asleep and sleeping well due to cognitive stimulation and sleep deprivation. Your brain’s electrical activity increases, neurons race and divert you from calming down into a peaceful state of mind for sleep.
The physical act of responding to an email, text, or video increases the tension in your body which results in stress. Your body then produces the stress hormone cortisol released by the adrenal gland, this is a sleep killer.
Too much light from video screens at bedtime affect the melatonin production giving the body the impression you aren’t ready for sleep. Screens emit light that suggests to the brain that it is still daytime which contributes to insomnia and sleep deprivation.
Holding a device such as a smartphone close to one’s face increases this effect giving the brain the wrong signal as if it’s not time to go to sleep. The best advice is to stop watching TV or using smartphones and other screen devices an hour or two before bedtime to give your brain a rest and the correct signal that it is time for sleep.
