Cold Plunging: Why 65°F is the Optimal Temperature for Wellness Benefits

The health benefits of cold plunging have gained attention in both sports and wellness industries due to the positive effects on the body. Cold plunges offer various physical and mental health benefits. By immersing in cold water regularly, individuals can experience the perks. 

Improving Overall Circulation:

Cold plunges improve circulation due to the body’s response to the cold water immersion. When individuals submerge themselves in cold water, the blood vessels constrict, reducing blood flow to the skin’s surface. Upon exiting the cold plunge, the blood vessels expand, increasing blood flow throughout the body. This cycle aids in improving overall circulation.

Reducing Inflammation:

The boost in circulation from cold plunges also helps in reducing inflammation. Cold plunges help reduce inflammation and support faster recovery following physical activity or injuries by decreasing blood flow to inflamed areas. The anti-inflammatory properties of cold plunges can also alleviate muscle soreness and deliver essential nutrients to the muscles for enhanced recovery. Additionally, the anti-inflammatory properties of cold plunges can reduce swelling and inflammation in the skin, positively impact skin health and appearance.

Boosting Immunity:

Cold plunges can boost immunity by stimulating the immune system to produce more white blood cells. This immune response, combined with increased circulation, enhances immune function over time. Additionally, the stress response induced by cold exposure can improve the body’s ability to adapt to stress, which in turn benefits the immune system.

Increasing Mental Health:

Cold plunges increase energy levels and enhance mental health by activating the sympathetic nervous system and releasing endorphins and adrenaline. This release can improve alertness, concentration and overall cognitive function. Cold plunges can also promote relaxation and improve sleep quality by relaxing muscles, reducing tension and creating a sense of calmness conducive to better sleep.

Cold Plunge Temperature Recommendations

The typical temperature range for cold plunging is around 50°F to 59°F. While colder temperatures can offer intense cooling benefits, it is crucial to be aware of potential risks associated with exposure to extremely cold temperatures. Starting with milder temperatures, such as 55°F to 65°F, is recommended, especially for beginners. This temperature still elicits a response from the body without the risks of extreme cold exposure. Consistency in temperature, like 65°F, can yield more predictable results from cold therapy sessions.

In addition, recent studies have highlighted gender differences in response to cold exposure, with women potentially benefiting from warmer temperatures for cold plunging. Women’s distinct body functions, including body composition, metabolic rates and hormonal variations, can influence their response to cold stress. Research suggests that providing warmer temperatures, starting at 55°F to 65°F, for women during cold plunging can help mitigate risks and stress responses from overexposure to cold stress. 

Cold plunging offers a range of health benefits, making it a valuable practice for overall wellness. Tailoring the temperature based on research and your individual goals can offer a more personalized approach to cold water immersion therapies.
