You may ask why this temperature, it's because at normal body temperature being 97 degrees Fahrenheit to 99 degrees Fahrenheit, cells need a regular oxygen supply. When the heart stops, blood no longer carries oxygen through the body, and the brain can only survive for a few minutes. At these reduced temperatures, however, tissue cells need less oxygen because all chemical reactions have slowed almost to a halt meaning cells require much less oxygen to function. This is why sometimes before heart or brain surgery, surgeons will lower a patient's body temperature with an external cooling system, to give themselves more time to operate on the patient. It's the same principal that has allowed some people to survive near- drowning in cold water, being submerged for a more than half an hour. involves replacing an entire blood supply with a solution of cold saline. The cold solution induces hypothermia and slows down the body's cellular activity. Thought as a solution to a patient will be difficult for some surgeons to get the authorization for this experimental
