It's similar to how red-light face masks work. These masks are usually worn for about 10 minutes and always have a light wavelength level in the 600-nm range (usually 630 to 660), like the HigherDose hat does, but you'll also see masks with higher infrared-light levels that promise healing and reduced inflammation. The hat delivers only the main red-light therapy level and features 120 medical-grade LED bulbs arranged in a half circle for easy wear around your head.
