With aging, it’s natural to feel more tired or have some loss of sex drive, even when engaging in a healthy lifestyle, that includes exercise and a reasonable diet. Red and NIR light wavelengths have been shown to stimulate energy production within the Leydig cells, which are the cells responsible for producing testosterone in the testicles. Enhanced energy production in Leydig cells is believed to help naturally increase testosterone production.
*Disclaimer: Be cautious and use common sense when using NIR, as it could heat up tissue.*
