A cold plunge or cold-water immersion involves partially or totally submerging yourself in cold water for a few minutes at a time. It can be as simple as sitting in a bathtub filled with cold water and ice cubes or jumping into a cold lake or the ocean. The water should be at 10 degrees Celsius. Top athletes like Cristiano Ronaldo use cold plunging as a part of recovery.
In a recent Vogue interview, Blackpink member Jennie shared how cold plunging is beyond a physical process for her. Bollywood celebrities like Kartik Aaryan and Vidyut Jammwal too have taken to Instagram to share glimpses of them cold plunging.
Benefits of Cold Plunging
In a 2016 study, researchers noted several studies that suggest cold plunging or cold water therapy can boost blood flow, reduce heart rate, and improve overall cardiovascular health. The same 2016 review suggests that cold plunges may have beneficial effects on metabolism and body fat, including a reduced risk of metabolic diseases and reduced body fat.
Adapting to the shock of cold water helps build mental resilience and discipline. Consistent exposure to cold temperatures allows the mind to get comfortable in a state of discomfort, which might improve your ability to deal with other types of stress. Immersion in cold water helps reduce chronic inflammation which helps in reducing depression, boosting the immune system, and also feeling more awake and alive.
The Risks of Cold Plunging
Of course, any practise you read on the Internet shouldn't be tried without taking suggestions from an expert.
Sudden cold-water exposure can cause your blood pressure and heart rate to spike, which can be particularly problematic for those with heart conditions. Extended cold-water exposure can cause hypothermia, which can be life-threatening in severe cases. For that reason, it’s best to keep plunges short — within a few minutes. The cold water can cause your airways to tighten, making breathing difficult. If you have a respiratory condition like asthma, always talk with your doctor before attempting a cold plunge.
