Does Blue Light Mess With Your Sleep Cycle?

There are probably plenty of reasonable things keeping you up at night. All of it is stressful, but there also might be something interrupting your sleep in a less tangible, conscious way: blue light.

 

Unbeknownst to you, blue light might be wreaking havoc on your sleep schedule. Sleep is one of the body's most essential functions. You don't exactly want to find out how long your body can be without it. Luckily, several sources report that there's a surprisingly simple solution to the problem.

Blue light blocking glasses are pretty self-explanatory. According to Healthline, these glasses allow your body to distribute melatonin more effectively and help you reach a deeper, more restful sleep. Harvard's Health Letter reported similar findings.

According to a study from the University of Houston College of Optometry published in the journal of Ophthalmic & Physiological Optics, blue light emitted from digital devices could be a reason for increased sleep dysfunction. Participants in the study who wore short wavelength-blocking glasses three hours before bedtime for two weeks experienced a 58 percent increase in their melatonin levels at night. Overall, the quality of their sleep reportedly improved significantly in many ways.

It's recommended that you avoid using a phone, tablet, or computer screen well before bedtime. That's not always possible, so instead, you have the option to don a pair of the often orange-tinted glasses a few hours before heading to bed. These five highly-reviewed pairs of blue light blocking glasses are the best out there. Hopefully, they'll eliminate at least one thing keeping you up at night.
