Doctors Warn of Extended Exposure to Blue Light


From our phones to computers to tv screens Americans are bombarded with blue lights, however,  nighttime exposure can be hazardous to your health.

Whether you’re binge-watching Netflix or scrolling through social media to wind down most of us are basking in the glow of a screen just before we turn in for bed.

However, Doctor Charles Czeisler of Brigham and women’s hospital says this exposure throws off our biological clocks.

In turn, the release of our sleep hormone melatonin is suppressed.

Dr. Charles Czeisler with Brigham and Women’s Hospital said, “we’ve done studies showing that if we read, for example, from an iPad in  the few hours before bedtime, that that resets our circadian clock by about an hour and a half later shifting our circadian rhythms repeatedly has been associated with increased risk with various types of cancers including colon cancer, Breast cancer, and prostate cancer.”

His best advice if you work nights or use a lot of devices at night use apps or settings that warm up the colors of your screen and most importantly avoid those bright screens two to three hours before bed.
