Alertness, Sleep and Circadian Rhythm

If you’ve had trouble sleeping, you might have heard about melatonin, the natural hormone your body makes to regulate sleep and wakefulness.

Exposure to artificial white light and blue light after dark inhibits the body’s ability to release melatonin, increasing the time it takes you to fall asleep and preventing you from staying asleep. If you use a high-quality Red/NIR light therapy device during the day, it’s been clinically shown to increase your natural melatonin output, which helps you get to sleep and stay asleep in a restful state.
