Improved circulation

Coldwater plunging causes vasoconstriction, which is the narrowing of blood vessels. When you expose your body to cold water, your blood vessels constrict, and when you come out of the cold water, they dilate, leading to improved circulation throughout the body. 

Enhanced immune system

Coldwater plunging has been shown to have a positive effect on the immune system. Cold exposure stimulates the production of white blood cells, which are essential for fighting off infections. Regular plunges can strengthen your immune system and make you less susceptible to illnesses.

Increased energy and alertness

Immersing yourself in cold water can activate your sympathetic nervous system, also known as the “fight or flight” response. This response releases adrenaline and increases oxygen intake, which can boost your energy levels and make you more alert and focused.

Mental/emotional well-being

Coldwater plunging can have a positive impact on mental health. The shock of cold water triggers the release of endorphins, which are natural mood enhancers. It can also help reduce stress and anxiety levels, improve sleep quality, and promote a sense of well-being.

Skin and hair health

Cold water helps tighten the pores, making the skin look smoother and reducing the appearance of acne and blemishes. It can also promote healthier hair by closing the hair cuticles and making the hair shinier and less prone to breakage.

Increased tolerance to cold

Regular cold water plunging can help improve your body’s ability to tolerate cold temperatures. Over time, you may find that you are more resistant to cold weather and have a higher tolerance for cold water, making you less likely to feel discomfort in chilly environments.

Increased Killer T Cells

Cold water immersion, particularly in the winter, can challenge the immune system and the way hormones communicate with the body. Studies have shown that regular winter swimmers experience adaptive reactions, including an increase in the production of the antioxidant glutathione. Just a few cold water sessions over a 6 week period can increase the number of lymphocytes, a type of immune cell. Some research has even found that males exposed to 39°F for 30 minutes had an increased number of “killer T cells,” which are cells that help to eliminate viruses. These findings suggest that cold water immersion may have immune-boosting effects on the body.

Immune Boost

There is widespread anecdotal evidence that suggests that cold water immersion can boost the immune system. Many people report feeling healthier and less prone to illness after regularly using a cold tub. While the immune system is complex and difficult to study, it is believed that the cold can help to adapt and harden the body to disease and infection. Despite the lack of robust scientific studies on this topic, many people believe in the immune-boosting benefits of cold water immersion.

Protein Power

Cold exposure can stimulate the production of a protein called PGC-1 alpha, which can increase metabolism at a cellular level. PGC-1 alpha is being targeted by pharmaceutical companies in the development of treatments for obesity, diabetes, and cardiomyopathy. In muscle tissue, the increased energy released from the production of PGC-1alpha can improve aerobic capacity and endurance, as well as increase resistance to fatigue.
