You’ve probably heard people who work late night shifts in hospitals, fire stations, restaurants, or on the road protecting our streets talk about how light during the day has a negative impact on their ability to get a decent amount of restful sleep. But, did you know there is a real reason behind it? It’s not merely a preference for darkness that’s robbing them of the recuperative sleep they need in order to wake up refreshed and ready to face the day. But why does light have such a profound impact on sleep and what can people who work these necessary late shifts do to get the kind of sleep they need?
Why Does Light Negatively Impact Sleep?
“In the presence of light, your brain will not produce melatonin,” says Dr. Michael Breus, PhD, Sleep Specialist: On the surface that doesn’t seem like such a profoundly negative thing. However, melatonin is one of the vital hormones that plays a significant role in helping people not only fall asleep but also to remain asleep throughout the night. If a room has too much light, that makes things much more difficult for anyone looking to get a proper amount of sleep.
