Emerging data suggests that light therapy offers a variety of health benefits. Absorption or reflection of light energy determines how light impacts the body. Different aspects of light exposure, including wavelength, duration, and intensity, can impact its ability to target human tissues. The longer the wavelength, the deeper it can penetrate the skin. Due to its long wavelength, red light therapy has been shown to improve sleep and enhance alertness by modulating hormone levels in the body. It has also shown benefit in those struggling with certain medical conditions, such as Parkinson’s Disease. Incorporating red light into a daily routine can be an easy yet beneficial way to enhance sleep and optimize daily performance.
