Cold showers and testosterone: does cold exposure boost your T?
Cold showers and ice baths are popular online as a testosterone hack. Here is what the evidence actually says about cold showers and testosterone.
In short: There is no good evidence that cold showers raise testosterone. Keeping the testicles cool can support sperm production, because sperm develop well slightly below body temperature. Cold exposure may improve alertness and mood for some people. Men with heart conditions should be cautious, as cold shock raises heart rate and blood pressure.
The claim
Social media often claims cold showers or ice baths boost testosterone. The idea likely comes from the fact that the testicles sit outside the body to stay cooler, which matters for sperm.
What research shows
Testosterone
Studies have not shown that cold showers or ice baths meaningfully raise testosterone. One study even found ice baths after strength training may reduce muscle gains.
Sperm
Heat harms sperm production, so avoiding hot baths, saunas and tight underwear helps. Cold showers themselves have not been shown to boost sperm, but keeping the area cool is sensible. See how to increase sperm motility.
Energy and mood
Some studies suggest regular cold showers may improve alertness, mood and the sense of wellbeing, and one large study found fewer sick days among people who finished showers with cold water.
Who should be careful?
Cold exposure triggers a “cold shock” response that raises heart rate and blood pressure. Men with heart disease, high blood pressure or heart rhythm problems should get advice before trying cold water immersion.
How to try cold showers safely
- Start with your normal shower, then finish with 15 to 30 seconds of cool water.
- Gradually increase to one to two minutes.
- Breathe slowly through the discomfort.
- Avoid ice baths without supervision.
What actually supports testosterone
- Sleep seven to nine hours. See lack of sleep and erectile dysfunction.
- Lose excess belly fat.
- Strength train.
- Limit alcohol and manage stress.
- Get enough zinc, magnesium and vitamin D. See magnesium benefits for men.
