Improves Sleep Quality, Fall Asleep Faster — During a red-light therapy session, retinal cells in the eyes perceive the light from the red light therapy device, affecting certain chemicals in your brain. These chemicals are melatonin and serotonin, and they are responsible for regulating your sleep-wake cycle. The perception of light delays your brain’s melatonin production, waking you up and lifting your mood.
Increases Energy Levels and Combats Chronic Fatigue — The primary function of red-light therapy is to increase energy production
The sun gives plants the energy they need to convert light energy into chemical energy. Similarly, red light gives our skin energy to charge our power cells, the mitochondria,” says celebrity aesthetician and dermatological nurse Natalie Aguilar. “With this energy, cells are able to repair themselves, become healthier, and can promote healing in skin and muscle tissue.”
Thankfully, the therapy itself does not hurt. “LED therapy is completely painless. For the most part, you feel nothing but a slight warmth,” says Aguilar.
