In physical therapy, cold water immersion will have the patient soaking in a cold plunge tub for a handful of minutes to help control joint inflammation and ease tense muscles. As an added benefit of the cold, the intense temperature of cold plunge cues the release of endorphins-s that help patients feel better.

The reason physical therapy techniques use a cold plunge tub to soak in rather than prescribing other cold water immersion methods is due to the design of a cold soaking tub. Their cooling system allows them to maintain water temperature around 50F. This is key to making sure the cold water immersion benefits needed for physical therapy are achieved.

When the body is exposed to the cold, its circulation system works harder to make sure the body generates heat and the organs still function.

This pressure promotes blood circulation, sending oxygen and nutrients to the organs and keeping one's body functioning more optimally for a few hours after your cold plunge therapy. Cold immersion, when done regularly, can lead to better blood circulation and have lasting improvements.

For hundreds of years, people claimed to feel better or notice improvements in their mental health after taking cold baths.

Modern researchers find that this is true—cold water immersion does increase the production of mood-elevating factors and neurotransmitters like norepinephrine and dopamine.

These physiological mechanisms help alleviate symptoms of depression and anxiety hence people with difficulties in mental health may find cold plunges therapeutic not, only physically but mentally and emotionally.

When it is cold, the body revs up its thermogenesis; this is the process of generating heat by burning brown fat cells to keep the body and its organs functioning.

Therefore, cold plunges serve as one of the easiest and safest ways of biohacking techniques available to reap the results of revved-up thermogenesis which is to burn fat.
