COLD PLUNGE THERAPY CAN CURE DEPRESSION
Some people who fail to respond to traditional talk therapy and anti-depressant medications have resolved their major depression with the benefit of whole-body cold-water immersion. In the Summer of 2024, I convened a panel of subjects who have each experienced significant relief from mood disorders in as little as one session of cold plunge therapy:
- One man confided that he had tried supplements, therapy, and everything he could think of... yet nothing was helping until he tried a Morozko ice bath. Cold plunge therapy became his stabilizer--like a rock that he can depend on, when nothing else was working.
- Another man was diagnosed with anxiety, OCD, and Tourette's syndrome when he was nine years old. His entire life since has been a struggle with mental health disorders. He discovered that swimming in a 38-degree cold river brought him relief from his anxieties and that all of the difficult thoughts and emotions he had been carrying went away.
- A third man described how his attempt at suicide by drowning was interrupted by the cold Baltic Sea. Once he plunged into the water, he found new sense of perspective, and he realized that he wanted to live.
There are several mechanisms, the most important of which are metabolic and neurochemical.
Metabolic
Cold therapy stimulates mitobiogenesis--i.e., creation of new mitochondria--that resolves metabolic disorders. Mitochondria convert blood glucose, lipids or ketones into ATP to power & provide energy for almost all processes in the body. This energy can be used to move muscles, repair tissues, or fuel growth.
When mitochondria are rejuvenated through cold exposure, insulin sensitivity improves, energy improves, and overall health benefits. However, when mitochondria are defective, and insulin resistance is high, brain function suffers.
Neurochemical
Hormones and neurotransmitters are released into the bloodstream in response to cold stimulus. These include the feel-good neurochemicals like dopamine and norepinephrine, and also bonding and attachment hormones like vasopressin and oxytocin. It is impossible to be in a bad mood when there is three times the levels of normal dopamine coursing through your bloodstream.
