Does Sauna Lower Testosterone?


Saunas have become increasingly popular in recent years, with many people incorporating sauna sessions into their wellness routines. These heated rooms are believed to offer various health benefits, from relaxation and stress reduction to improved cardiovascular function. However, there are concerns about the impact of saunas on testosterone levels, particularly among men. In this article, we will explore whether saunas lower testosterone and uncover the truth behind this claim. So, sit back, relax, and let’s dive into the sauna-testosterone relationship!

Understanding Testosterone:

Before delving into the sauna-testosterone connection, it’s important to have a clear understanding of testosterone. Testosterone is a hormone primarily associated with male reproductive health, although it also plays a role in women’s health. It is responsible for the development of male sexual characteristics, such as the deepening of the voice, muscle growth, and facial hair. Additionally, testosterone influences libido, bone density, and overall well-being.

The Science Behind Sauna Sessions:

Saunas are typically heated to temperatures ranging from 70 to 100 degrees Celsius (158 to 212 degrees Fahrenheit). During a sauna session, the body is exposed to these high temperatures, leading to an increase in core body temperature. This rise in temperature triggers various physiological responses, including increased heart rate and dilation of blood vessels. As a result, blood flow to the skin’s surface increases, promoting sweating and ultimately cooling down the body.

The Impact on Testosterone Levels:

There is limited scientific research specifically focusing on the direct impact of saunas on testosterone levels. However, some studies have shed light on related aspects that indirectly suggest saunas may not significantly lower testosterone.

1. Studies on Heat Exposure:

Research conducted by Jari Laukkanen and his team at the University of Eastern Finland investigated the impact of heat exposure, including sauna sessions, on men’s testosterone levels. The study involved 50 men who participated in four separate sauna sessions per week for three weeks. The results showed no significant changes in testosterone levels after the sauna sessions. This suggests that saunas may not have a substantial impact on testosterone.

2. Post-Exercise Testosterone Levels:

Another aspect to consider is the effect of saunas on testosterone levels following exercise. Exercise has been shown to temporarily increase testosterone levels, and some individuals wonder if saunas might counteract this effect. However, a study published in the Journal of Science and Medicine in Sport found that sauna use after strength training did not significantly affect testosterone levels. Therefore, saunas are unlikely to hinder the post-exercise elevation of testosterone.

3. Short-Term vs. Long-Term Effects:

It is worth noting that the studies conducted so far have mainly focused on short-term sauna exposure. Long-term effects of regular sauna usage on testosterone levels have not been extensively explored. However, based on the available evidence, it seems unlikely that regular sauna sessions would have a significant impact on testosterone levels.

Frequently Asked Questions (FAQs):

Now that we have explored the relationship between saunas and testosterone, let’s address some frequently asked questions to further clarify the topic.

1. Can saunas cause a temporary decrease in testosterone levels?

Based on the current scientific knowledge, saunas are unlikely to cause a temporary decrease in testosterone levels. Short-term sauna exposure does not appear to have a significant impact on testosterone. Therefore, you can enjoy your sauna sessions without worrying about an immediate decrease in testosterone.

2. Can saunas affect testosterone production in the long term?

As mentioned earlier, there is limited research on the long-term effects of saunas on testosterone production. However, based on the available evidence, it is unlikely that regular sauna usage would have a substantial impact on testosterone levels in the long term. Therefore, you can continue to enjoy saunas as part of your wellness routine without significant concern.

3. Are there any other factors that can affect testosterone levels?

Yes, several factors can influence testosterone levels. These include age, stress levels, sleep quality, diet, exercise, and underlying medical conditions. It is important to consider these factors holistically when assessing testosterone levels rather than focusing solely on sauna usage.

4. Can saunas offer any other health benefits?

Absolutely! Saunas have been associated with various health benefits, including relaxation, stress reduction, improved cardiovascular function, and enhanced recovery after exercise. Additionally, sauna sessions can promote sweating, which may help detoxify the body by eliminating toxins through the skin.


After examining the available scientific evidence, it appears that saunas are unlikely to lower testosterone levels significantly. Short-term sauna exposure does not appear to have a direct impact on testosterone, and there is limited research on the long-term effects. Therefore, individuals can enjoy sauna sessions as part of their wellness routine without worrying about negative effects on testosterone levels. As always, it is essential to consider various factors that may influence testosterone, such as age, stress, and overall lifestyle choices. So, go ahead, relax, and embrace the benefits of a sauna session without concerns about your testosterone levels!
