The Truth About Blue Light: It’s Not All Bad


The key point to remember is that humans are biologically programmed to follow light/dark cycles in order to entrain hormone production and bodily functions. So, exposure to blue light — specifically sky-blue wavelengths — during the daytime is not only healthy for you, it’s critical for regulating your circadian system and helping you function your best.  At nighttime, be sure to minimize light exposure all together; this signals to the brain that the sun has descended below the horizon and it is time for the body to wind down for a good night’s sleep.
