Glow of Modern Gadgets at Night May Disrupts Sleep
Long before, researchers have found out that light can hold back melatonin, a hormone that helps generate sleep. Nowadays, even after sunset, people are still flooded with lights, whether through texting, internet browsing or watching television. According to Dr. Steven Lockley, of Harvard University and a co-author of “Sleep: A Very Short Introduction, when people expose themselves to light at night it become unnatural for them to do making themselves believe that it’s a daytime. Light makes it harder for a person to catch some sleep and shift the body’s internal clock, or circadian rhythm. However, there is actually one kind of light that is more disturbing than others. The American Academy of Sleep Medicine (AASM) claims that blue wavelengths, the kind of light emitted by energy-efficient light bulbs and electronic gadgets such as cellphones, computers and TVs should be avoided.
