![]() ![]() Need proof that sleep masks can improve your rest? One study was conducted on subjects in an environment made to resemble an ICU (an environment with a high amount of light and noise disruption). Having constant light peek through your window such as that from a street lamp, a car driving by, or even the moon may delay the production of melatonin, and for sensitive sleepers, even wake you up at night. Although, it should be noted that humans are especially sensitive to blue light - check out this study. It’s been found that room light (any light that provides general illumination for a room) can confuse the body’s circadian rhythm and delay the production of melatonin, the hormone that regulates the sleep/wake cycle - not just the “blue light” emitted from phones and screens. Sounds simple, right? However, in a world filled with more light than ever, true “darkness” is becoming harder and harder to come by. We may be more productive, but we’re also sleeping less: in 1910, most people slept 9 hours per night now, one-third of Americans are getting less than 7 hours of sleep on a regular basis.Įach person has a circadian rhythm that helps their body figure out whether it’s time to be asleep or awake, based on light - light helps the body know it’s time to be awake darkness helps the body know it’s time to be asleep. And now, we have more distractions than ever before that bring light into the night, from cars driving past our windows to phone and laptop screens. Whether it be a candle or a lightbulb, humans have historically found a multitude of ways to get around the darkness that nighttime brings.
