Cold water immersion and ice baths may significantly increase testosterone levels in men through the effects of stress and dopamine activity in the brain. While exposure to cold water can stimulate the body’s natural response mechanisms, including increased circulation and hormone release, scientific studies suggest that the rise in testosterone may be temporary. Nonetheless, cold showers likely confer some metabolic and mitochondrial benefits that support healthy levels of testosterone, compared to no cold exposure at all. In extreme cases, the combination of cold water and exercise can put too much stress on mitochondria in ways that temporarily suppress testosterone levels. Whether it’s boosting testosterone levels, aiding muscle recovery, or enhancing mental clarity, the potential benefits of ice baths are certainly intriguing. To ascertain how ice baths can contribute to other health benefits for women, additional exploration into the effects of cold on female hormones is necessary. Over time, as your body adapts to the cold stress, you may start to notice improvements in your overall well-being, energy levels, and potentially, your testosterone levels.
Several medical doctors and scientists have published social media posts claiming the opposite of my experience -- even as lab reports and case studies from men and women have come pouring in from readers all over the world corroborating my research. In September 2017, I was a 51-year-old engineering professor with an elevated prostate-specific antigen (PSA) of 7.0 ng/mL and an incidental finding of high-normal total testosterone (736 ng/dL). Dive into expertly crafted content on supplements, longevity, and optimizing your mind and body for peak performance. BrainFlow is your trusted hub for health, wellness, and biohacking insights. Your ice bath practice should follow a progressive path—start modest, build gradually, and maintain regularity. Cold therapy offers a simple, accessible approach to fighting back. Consistency trumps frequency—two strategic sessions weekly sustained over months yields better results than daily exposure for two weeks followed by abandonment.
Their mean testosterone levels jumped from 4.04 ng/mL to 4.25 ng/mL — an increase of more than 5%. In that study, young men were immersed in cold water after a sauna session, sometimes referred to as contrast therapy. Research suggests that cold water immersion could help boost sexual wellness — naturally. Because sex hormone synthesis originates in the mitochondria, the focus of our testosterone-boosting protocol is mitogenesis -- i.e., production of new mitochondria. In both sexes, testosterone builds healthy muscles, helps maintain lean body composition, and boosts libido.
The Ice Barrel makes it easy to soak in cold water in the comfort of your own home. A BMJ case report detailed a young woman with severe depression and anxiety who, thanks to weekly cold water swimming, was able to reduce her symptoms and become medication-free. Low levels of these key sex hormones could translate to a lower sex drive and leave you wondering how to increase sexual energy.
Research shows that zinc deficiency can significantly suppress testosterone, while restoring adequate levels supports hormone balance, recover... It can support hormonal health indirectly, but it is not a testosterone booster. Cold plunges won’t magically boost testosterone, but they support the systems that regulate hormonal balance, especially stress. This suggests that cold showers may boost the immune system, even though there was no effect found on how long people were sick.
As with any new practice, it’s wise to consult your physician before beginning an ice bath regimen. Additionally, having a dedicated cold plunge tub can be a motivating factor in maintaining your routine. A 2018 study found cold temperatures markedly raised blood melatonin concentrations.
