Therapeutic hypothermia is a medical treatment strategy that involves intentionally lowering a person's body temperature in order to slow down certain biological processes and protect the body's tissues. This technique has been shown to be effective in preventing or reducing damage to the brain and other organs following events such as cardiac arrest, stroke, or traumatic brain injury. Therapeutic hypothermia works by decreasing the metabolic rate and inflammation, as well as preserving cellular function and preventing cell death. It is typically achieved through the use of cooling blankets, ice packs, or intravenous infusions of cold fluids, and is carefully monitored and controlled by medical professionals to ensure patient safety.
