Sunshine boosts sex drive
An hour of sunbathing can boost a man’s testosterone levels – and his sex drive – by 69 per cent, European researchers reported in the Daily Telegraph have found.
Sunshine is vital to boosting Vitamin D levels, and the new study shows Vitamin D is essential for good testosterone levels.
Stimulated by UV radiation, 90 per cent of Vitamin D in the body is produced by the skin, although it can be found in cold water fish like tuna and salmon, and in cod liver oil.
And while sunscreens with a sun protection factor of 8 or greater will block UV rays that produce Vitamin D, but it is still important to routinely use sunscreen whenever sun exposure is longer than 10 to 15 minutes.
Testosterone Fluctuates With Sunshine
Researchers at the Medical University of Graz in Austria found men with more Vitamin D per millilitre of blood had much more of the main male sexual hormone circulating than those with less.
And the average amount of testosterone over the course of the year was subject to the same fluctuations as the Vitamin D level.
Both decrease from October – at the beginning of the winter months – and reach their lowest level in March because of the weaker solar radiation during this period.
Not Enough Sun
Season, latitude, time of day, cloud cover, smog, and sunscreens affect UV ray exposure, so if you live somewhere with little sun, it is especially important to include good sources of Vitamin D in your food.
In Boston – for example – the average amount of sunlight is insufficient to produce significant Vitamin D synthesis in the skin from November through February.
Ad Brand, spokesman of the Sunlight Research Forum in Veldhoven in the Netherlands, said: “Men who ensure their body is at least sufficiently supplied with Vitamin D are doing good for their testosterone levels and their libido among other things.”
Best Foods For Vit D
While sunshine is the most effective Vitamin D source, it can also be obtained by eating fatty fish –cold water varieties like salmon, mackerel, tuna and sardines, by taking cod liver oil, eggs, beef liver, or UV irradiated mushrooms.
Foods like cereals and milk are now routinely fortified with Vit D.
Testosterone is the most important male sexual hormone. In males it is mainly responsible for the development of the sex organs, the formation and maintenance of the typical male sexual characteristics, sperm production and the controlling of male desire.
