Cold Plunging & Sexual Health
The Fertility Problem
Fertility rates in industrialized nations have been declining dramatically in recent decades. Sperm counts have dropped by over 50% since the 1970s, and testosterone levels are decreasing even among young men. Women are increasingly affected by conditions like polycystic ovary syndrome (PCOS).
What’s Causing It?
These reproductive health issues are closely linked to metabolic dysfunction, which can manifest as either starvation or overfeeding. While cold therapy isn’t suitable for addressing caloric deficits, it may offer benefits for those dealing with the metabolic consequences of modern, carbohydrate-heavy diets.
How Can We Fix It?
The simple answer is: “Get cold.”
For men, cold therapy may enhance erectile function and increase testosterone levels. Studies have shown that combining a low-carbohydrate diet with cold exposure can significantly boost testosterone and improve sexual function in men with initially low levels.
In women, cold exposure may help address PCOS, a common cause of infertility associated with insulin resistance and metabolic disorders. Research on animals with PCOS found that cold treatment restored normal menstrual cycles and improved pregnancy rates.
How Can Cold Exposure Help?
Cold exposure activates brown adipose tissue (BAT), which can help reverse insulin resistance and provide various metabolic benefits. Unlike white fat that stores energy, brown fat burns it to generate heat. Stimulating brown fat through cold exposure can potentially improve insulin sensitivity and hormonal balance.
Specific to women, ice baths could have a modulating effect on testosterone levels, potentially lowering it in cases where it’s abnormally high (as in PCOS) and raising it in healthy women who might benefit from the boost. However, cold therapy may not be beneficial for infertility caused by insufficient body fat or energy deficits.
The mechanism behind these benefits involves activating and recruiting brown fat, which can help correct metabolic disorders and modulate aberrant testosterone levels.
For men, exercising to rewarm after cold immersion can further boost testosterone levels and may encourage sperm production by cooling the testes.
Interestingly, while cold therapy may be beneficial, heat exposure through saunas is not recommended when trying to conceive. Saunas may reduce sperm production in men and are associated with reduced conception rates and poorer birth outcomes in women.
Keep Metabolism in Mind
For couples seeking to conceive, considering the metabolic aspects of sexual function and fertility is crucial. Cold exposure, combined with sufficient protein intake and low consumption of linoleic fats, may promote fertility in both men and women. However, it’s essential to maintain proper nutrition alongside cold exposure, and to recognize that cold therapy isn’t appropriate in all situations.
This approach to addressing fertility issues, particularly those related to metabolic dysfunction, offers a promising avenue for couples struggling to conceive. However, it’s important to note that the benefits and limitations of cold therapy for reproductive health are still being studied, and individual responses may vary.
