Cold Water Immersion Therapy Benefits

This month we are taking a deep dive (no pun intended) into the practice of cold plunging! Cold plunging has been a tradition in certain cultures for many centuries and is now regaining popularity in our modern times by wellness enthusiasts around the world. Also known as cold immersion therapy, it involves immersing yourself in cold water, ideally ranging from 40-60 degrees fahrenheit for 1-3 minutes. Read on to learn about both the mental and physical health benefits cold plunging can induce. 

As someone that is not a fan of swimming or cold temperatures, even I have hopped on the cold plunging trend and find myself wanting to keep going back for more. After doing it consistently 2-3 times per week for a couple of months now, I am absolutely feeling the benefits. I feel an uptick in my mood, am sleeping more soundly, and definitely feel that my body temperature is more regulated (I was the person in the room that was always cold when others were not!). Obviously this is all anecdotal, so let’s jump into what the studies are finding.

A systematic review found that regular cold water immersion significantly reduces the symptoms of depression and anxiety. The shock of cold water triggers the sympathetic nervous system, releasing endorphins, the body's natural painkillers, leading to a euphoric and calm feeling post-plunge. The World Economic Forum also reports that it can reduce symptoms of depression by “activating cold receptors on our skin and sending a vast amount of electrical impulses to the brain. However, care must be taken during cold immersion, as the shock can trigger a fight-or-flight response that can increase our heart rate and blood pressure”

A study involving 3,000 participants showed that 74% reported improvements in mood and 65% reported increased energy levels after cold plunging.

Athletes have used cold plunging to speed up recovery for decades. Immersing in cold water reduces muscle inflammation and soreness after intense physical activities. According to research published in the Journal of Physiology, cold water immersion was effective in reducing muscle soreness by up to 20%.

Cold plunging has been linked to an improved immune system. A study in the Netherlands found that people who shocked their bodies by going from hot to cold showers for 90 days called out sick 29% less than people that did not practice the cold showers. The shock of cold water can stimulate the blood cells that fight off infection (leukocytes).

Emerging evidence suggests that cold plunging can help people lose weight by promoting the conversion of white fat into brown fat, the type that burns calories to generate heat. A study by the Journal of Clinical Investigation in 2014 showed that regular exposure to cold can increase brown fat activity, enhancing fat burning and metabolism. Furthermore, the increased brown fat also helps insulin stability and blood sugar control, which also benefits metabolism and, therefore, can aid in weight loss.

While the benefits are compelling, it's crucial to approach cold plunging with caution, especially for beginners. Always consult with a healthcare professional before starting, particularly if you have cardiovascular issues or other health concerns.

As we've seen, the cold plunge is more than just a trend; it's a scientifically backed practice with numerous health benefits. Whether you're looking to boost your mood, enhance physical recovery, improve your immune system, or even aid in weight loss, taking the plunge might be worth considering. Remember, always prioritize safety and start slowly to acclimate your body to the cold.
