The Sun and Testosterone

Spending a day at the beach watching bikini’s and muscled men are not the only reason men and women get that “excited” feeling. It turns out that the sun actually increases Vitamin D, and as this vitamin goes up in our bodies, researches have found that so does testosterone.

At 40 to 60 percent more in men than women, testosterone is the primary hormone in men related to sex. It controls muscle growth, linear growth, and bone density. It’s also important in mental and physical energy, and erectile function.

Medical University of Graz in Austria has been studying the boost of testosterone level in men due to sunlight. Sunlight is actually responsible for up to 90% of our supply of vitamin D. We also get vitamin D in smaller percentages from oily fish, meat, and vitamin supplements.

The Graz researchers found that as your vitamin D levels drop, so does your testosterone levels. When exposed to an hour of sunlight, men receive over a 65% boost in vitamin D, which consequently also increased the testosterone level. During the study they also showed that men’s testosterone and vitamin D levels were sharply lower in the winter months as they were in the summer months.

Think doctors will start prescribing sunshine as a natural erectile dysfunction cure? Probably not, but remember this, on the sunny days out there, try to spend an hour in this natural energy giving gift.
