Electronics Reduce Melatonin Production
Blue light wavelengths produced by electronics boosts attention, reaction times and mood. This can be great for the daytime when the body needs to be alert, but at night it can become a problem. The bright blue lights from mobile phones, tablets, computers, and televisions blocks the release of the sleep hormone melatonin. Melatonin’s main job in the body is to regulate night and day cycles or sleep-wake cycles. Darkness causes the body to produce more melatonin, which signals the body to prepare for sleep. Light decreases melatonin production and signals the body to prepare for being awake. The absorption of bright blue lights through the eyes delays the release of melatonin, making it more difficult for people to fall asleep.
