Lack of sleep is a villain in America and Europe. Light intake is a big part of the problem. Over 65% of adults say they don’t get enough good sleep every week. Most people also don’t get nearly enough natural light for optimal health: the average American spends over 90% of their time indoors.

In addition to not getting enough natural light, people today are surrounded by artificial blue light from screens and overhead lighting. An overload of artificial blue light can cause headaches and make it harder to get to sleep and stay asleep. When we take in all that bright blue light from laptops, TVs, and phones, especially before we go to bed, our bodies get the signal that it's time to be awake, even if we're tired.

Melatonin is the naturally-occurring hormone that regulates sleep and wakefulness. Emerging research is showing that red light therapy treatments can help people produce more of their own, natural melatonin than exposure to other light sources like blue light. Red light therapy is natural light. It’s much less bright than blue light, with a lower color temperature than daytime sun, as the image above shows. Research has shown that red light doesn’t upset your sleep cycle like bright blue light. Red light therapy is showing great clinical results for people with insomnia and sleep disorders.
