In this video, Ben shows how to use http://BenGreenfieldFitness.com/JOOVV to triple testosterone production, boost fertility, and increase testicular health. Ben talks about this and many other ways to biohack your testosterone in the article at: https://bengreenfieldfitness.com/2016/09/how-to-biohack-your-testosterone/
CAUTION: Be sure to use the correct spectrum of light so that you don't damage your testicles or sperm. This is why Ben recommends the JOOVV light, which emits red light in a tight spectrum of 660 nm.
Most organs and glands of the body are covered by several inches of either bone, muscle, fat, skin or other tissues, making direct light exposure impractical, if not impossible. However, one of the notable exceptions is the male testes.
Is it advisable to shine red light directly on one’s testicles?
In most cases, red light therapy directly on the testicles for short, regular periods would raise testosterone levels over time.
Downstream this would lead to a holistic effect on the body, raising focus, improving mood, increasing muscle mass, bone strength and lowering excess body fat.
WARNING: Type of light exposure is crucial
Red light can come from a variety of sources; it is contained in the wider spectra of sunlight, most home/work lights, street lights and so on. The problem with these light sources is that they also contain contradictory wavelengths such as UV (in the case of sunlight) and blue (in the case of most home/street lights). Additionally, the testicles are especially sensitive to heat, more so than other parts of the body. There’s no point applying beneficial light if you are simultaneously cancelling the effects with harmful light or excess heat.
Blue & UV light’s effects
Metabolically, blue light can be thought of as the opposite of red light. While red light improves cellular energy production, blue light worsens it. Blue light specifically damages the cytochrome enzyme in mitochondria, preventing ATP and carbon dioxide production. This can be positive in certain situations such as acne (where the problematic bacteria are killed), but over time in humans this leads to an inefficient metabolic state similar to diabetes. UV or ultraviolet light is even worse, having all of the negative aspects of blue light magnified, and able to penetrate the skin deeper – exerting damage on a more profound level.
Red Light vs. Sunlight on testicles
Sunlight has definite beneficial effects – vitamin D production, improved mood, increased energy metabolism (in small doses) and so on, but it is not without its downsides. Too much exposure and you not only lose all benefits, but create inflammation and damage in the form of sunburn, eventually contributing the skin cancer. Sensitive areas of the body with thin skin are especially prone to this damage and inflammation from sunlight – no area of the body more so than the testes. Isolated sources of red light such as LEDs are better, with none of the harmful blue & UV wavelengths and so no risk of sunburn, cancer or testicular inflammation.
Don’t heat the testicles
Male testicles hang outside of the torso for a specific reason – they operate most efficiently at 35°C (95°F), which is a full two degrees below normal body temperature of 37°C (98.6°F). Many types of lamps and bulbs used by some for light therapy (such as incandescents, heat lamps, infrared lamps at 1000nm+) give off a significant amount of heat and therefore are NOT suitable for use on the testicles. Heating the testicles while attempting to apply light would give negative results. The only ‘cold’/efficient sources of red light are LEDs and low level lasers.
Red or infrared light from an LED source (600-950nm) can be safely applied to the testes without risk of side effects or damage
while delivering all of the benefits as detailed above (improved fertility, improved testosterone production, etc.).
Low level lasers are equally safe, albeit much more expensive.
Sunlight can also be used on the testes but only for short periods and it is not without risks.
Avoid exposure to blue/UV.
Avoid any sort of heat lamp/incandescent bulb.
Stick to LED light therapy for maximum safety and benefits. Visible red (600-700nm) LEDs are optimal. Session time from 2-20 minutes depending on light strength/heat.
