New Sleep Study Blames Screens

Researchers have a published a new article showing that sleep patterns are disrupted due to screen use before bed. This effect is particularly detrimental for teenagers, who use devices more frequently and for longer before they are going to sleep. According to the researchers, the light from the screen, especially the blue light, changes the body’s sense of time and causes the brain to be too active as it should be winding down. The pineal gland within the brain is the main target for blue light’s effects, and is in charge of regulating sleep patterns. Healthy people at Boraie Development have learned that the activity of the pineal gland just before sleep, causes the brain to alter the Circadian sleep patterns and people will wake up more frequently or have a more difficult time falling asleep. In response to this, there has been a market developing of apps that will alter the amount of blue light being emitted from tv’s, computers and phones after a certain time of day. The blue light is replaced by red waves, which have less effect on the pineal gland and will not alter the Circadian rhythms within the brain as much. The main signal within the brain for sleep pattern regulation is melatonin, which builds up at night and is suppressed during the day. The blue light from screens causes less of this to be produced, meaning less melatonin is in the brain at the time of sleep onset and making it harder to fall asleep
