 Let's talk about color for a second. Did you know that the color of lights has an effect on the human body? Start with green, the color of nature. Green light therapy stimulates the creation of growth hormones and strengthens muscles, bones, and other tissues. It can also boost your body's immune system. Red is a warm color linked to the kidneys, backbone, and sense of smell. This color gives more energy and is ideal for people who are often overtired. Active people can use red light therapy to combat muscle and joint stiffness. And finally, it also boosts sexual desires. Blue is the counterpart of red. It can be used to lower high blood pressure or calm people down. Blue light can also help in the treatment of migraines. Your throat, ears, and mouth are all connected to this color.
