CNN —Red light therapy has been found to be helpful for skin health, wound healing, hair growth among people with alopecia and pain management. “That’s why when we talk about blue light or red light, we’re not talking about a red-colored light bulb. A 2019 study led by Figueiro looked into whether delivering red light to closed eyes during sleep — using a red light mask — and to open eyes upon waking — via red light goggles — reduced sleep inertia among 30 adults. In other words, it might be that any benefits come from replacing the light you’re exposed to before sleep with red light, rather than adding the latter during sleep. The bottom line is that when it comes to sleep, “what’s better than red light is no light,” Dasgupta said.
