Use of the red part of the light spectrum You already know about the dangers of blue light before going to bed. What about red light? Different parts of the spectrum have different effects on a person's emotional and physical well-being. Red light can be used effectively to reduce nervousness and stimulate healing mechanisms.
It also relieves stress and improves metabolism. Besides that, it helps you sleep deeper and rest better during sleep, reduces headaches, stuffy nose, sore throat and earaches, and coughs. Red light increases the production of melatonin and enhances muscle tissue regeneration.
All this is especially relevant for people living in megacities, who
spend very little time outside and experience a shortage of sunlight.
