Step 1: Sportsman enters the cryosauna
After entering the cryosauna, a cold flow of nitrogen and air mixture activates thermoreceptors in the skin. These start to send electrical impulses to the brain. The CNS identifies a state of threat. This activates a complex adaptive reaction focused on defending the body to survive in an extremely cold environment.
Step 2: Vasoconstriction
The central nervous system sends signals to the muscles and vascular system, invoking contraction of muscles and narrowing of the blood vessels. This accelerates the flow of blood, nutrition and other resources from peripheral body parts to the body core.
Step 3: Detoxification and blood enrichment
In order to swiftly supply enough nutritional substances to core organs, the body starts hyperproduction to enrich blood with erythrocytes, oxygen, collagen and other essential substances. Metabolites and toxins are quickly degraded and eliminated.
Step 4: Vasodilatation
After leaving the cryosauna, thermoreceptors recognize the return to normal environment, which triggers vasodilatation and the return of enriched blood to peripheral body parts. Nutritional substances transferred by blood are absorbed by peripheral systems – muscles, tissues, joints and skin.
