Health Benefits of Cold Water Therapy
Stepping into icy water might feel like a shock at first, but the benefits are well worth it. Cold water therapy has been used for centuries to boost mood, reduce stress, and improve overall health. Backed by science, it can enhance circulation, support immune function, aid metabolism, and even build mental resilience. Whether it’s a cold shower or an ocean dip, embracing the cold could be a game-changer for your wellbeing.
lowers stress and improves mood
Cold water immersion causes a shift in your parasympathetic nervous system, activating your vagus nerve. Parasympathetic activity increases which reduces cortisol & increases production of certain hormones and neurotransmitters such as dopamine, improving mood. Research has shown a decrease in perceived stress. (source, source)
can boost immune function
Cold water immersion may help to boost immune function by increasing the production of white blood cells and blood concentrations of catecholamines, which activate the immune system. PMID:8925815
can help with weight loss & metabolism
Cold water immersion activates brown fat.
Brown fat helps you burn calories by creating heat right before your body starts to shiver (thermogenesis). It also helps regulate sugar (glucose) and fat metabolism. It releases powerful fat burning hormones.
can reduce inflammation
Exposure to cold causes blood vessels to constrict, reducing blood flow to injured areas, which helps reduce swelling and inflammation.
As it boosts the immune response, it also produces more anti-inflammatory chemicals and less pro-inflammatory cytokines. PMID:5285720
can increase mental alertness and decrease fatigue
Can help improve circulation and oxygen flow to the brain, which can enhance cognitive function and alertness. (source)
can reduce muscle soreness and improve circulation
The cold water helps to decrease inflammation and flush out waste products that contribute to muscle soreness. Cold immersion can help improve circulation by constricting blood vessels and then dilating them. This can help to bring oxygen and nutrients to the body's tissues, which can improve recovery and overall health. PMID: 4706272.
increases mental resilience
Overcoming the resistance of entering cold water can help us to build mental resilience. This can also help with self confidence and self esteem. If you can do this HARD THING, you can do others!
