You may be thinking do cold showers increase testosterone? Long, steamy hot showers are one of life’s simple yet exciting pleasures. But as relaxing and rejuvenating as they are, sometimes they are just not what your testosterone levels need. You see, according to science, rinsing your genitals with cold water may boost your T levels. That is actually the reason why hardcore weightlifters from Russia used to soak their bodies in cold water before they started those reps. So, here is everything you need to know about taking a cold shower and its effect on testosterone.
Cold Showers Testosterone: The Anatomy
As much as guys insist that cold showers have nothing to do with increased testosterone levels, science proves them wrong. But, first things first. Before jumping into the scientific evidence that shows the connection between these two, we need to set the record straight. Have you ever wondered why male genitals are placed outside a guy’s body? Unlike the female gonads, the male gonads need to stay cooler than the other parts of the male body. This way they reach optimal temperature (usually cool enough) and don’t risk the chance of destroying DNA, RNA and impairing testosterone synthesis in the male testes.
But, this is not the only proof that male genitals need to avoid heat exposure to maintain healthy testosterone levels. At this point, nature intervenes by equipping male gonads with the following reactive response. As soon as the temperature of the body rises, male genitals tend to “sag” a tad and lower towards the ground in an attempt to stay away from your body’s heat. On the other hand, when it’s cold, not only do male genitals remain where they usually are, but they also tend to go higher and tighten.
See? Even your body shows you that cold temperatures are much better when it comes to certain testosterone-like functions. But, let’s see what science has to say about this.
Cold Shower Testosterone: The Science
Still not convinced that cold showers and testosterone go hand-in-hand? According to a recent study in monkeys (following a rodent one with the same logic), turning up the heat when it comes to male gonads results in significant decrease in serum testosterone levels after only being exposed for two weeks. If we read between the lines, a decline in testosterone translates to reduced semen production, impaired athletic performance, and lower libido.
To confirm that, a more recent study examined the effect of seasonal temperatures to the reproductive and sexual potency in males. Even though it seemed like a long shot at first, the results were extremely surprising. The sperm concentration and motility were significantly decreased from spring to fall when they started recovering during the winter. This scientific result is real evidence that taking a cold shower can have a major effect on how to increase testosterone levels.
Last but certainly not least, one in-vitro human study suggests that high temperature in gonads may impair the synthesis process of DNA, RNA, and protein. In other words, when it’s hot the human male genitals have a hard time doing their job and, thus, produce less testosterone. The same study also claims that the optimal temperature for the male human testis to function properly is between 31 to 36oC (87 to 96oF).
The Final Verdict On Cold Water and Testosterone
Refuse to lead a life where toasty-warm showers get replaced by icy cold ones? You might need to reconsider. No one said that taking cold showers should be your only option. However, rinsing your body, and especially your genitals, with cold water is not that bad once in a while as heat seems to be a major testosterone anti-booster. Keep in mind, though, that science proves the effects are not instant. It may take some time for them to kick in.
