Research Shows Blue Light's Effect on Skin

Heavy phone, computer, or tablet use is bad for our health. 

In addition to "doomscrolling," toxic productivity from overwork, & other psychological impacts, digital devices emit blue light, a high-energy, short-wavelength kind of visible light. 

This can cause dry eye, cataracts, & macular degeneration, according to the International Journal of Ophthalmology.

 Chronobiology International showed that late-night blue light affects melatonin production, affecting sleep quality. 

Poor posture, headaches, digital eye strain, & overuse injuries can cause pain or stiffness in your upper body, arms, & hands. 

We understand. Plus more. Blue light can damage skin, doctors say. 

Blue light may penetrate skin. Blue light, like ultraviolet (UV) light, may cause long-term harm, warns board-certified dermatologist Rebecca Marcus, MD. 

"It's certainly leading to collagen breakdown, wrinkles, & hyperpigmentation gradually," Dr. Marcus tells The Healthy @Reader's Digest. 

Blue light exposure promotes "oxidative stress" by forming free radicals, according to a study. Dr. Marcus: 

"This damages DNA." Damage breaks down collagen & elastin, substances that maintain skin firm & youthful.
