A recent study by the Austrian Medical University of Graz found that sun exposure boosts testosterone levels in men.
Sunlight is responsible for 90% of the body’s supply of Vitamin D, which can be absorbed in smaller amounts through vitamins, meat, and oily fish. Graz researchers discovered that as Vitamin D increases, so does testosterone.
Testosterone is the primary sex hormone for men, appearing at frequencies of forty to sixty times that of females. It controls a number of functions in men’s health, including muscle growth, bone density, linear growth, the development of secondary sex characteristics, mental and physical energy, libido, and erectile function.
