First, you enter a chamber that is cooled with liquid nitrogen gas. The gas is inert certified medical grade N₂. The temperature in the chamber drops to a max -120°C (-184°F) over a period of 2-3 mins. The extreme dry cold sends electrical impulses to the central nervous system for the body to enter the fight or flight survival mode. The body's defence mechanism is activated and blood rushes to vital organs to protect them from extreme temperatures. Now that the blood has entered the core, it is enriched with oxygen, erythrocytes, collagen, and other beneficial nutrients during a hyper production period. After exiting the chamber, rapid vasodilation occurs to flood the nutrient dense blood to muscles, tendons, ligaments, skin, and soft tissue. Your body is now privy to the release of these valuable naturally occurring molecules that are active in reducing inflammation, relieving pain, and increasing metabolism.
