Brain cooling, also known as therapeutic hypothermia, is a medical treatment that involves lowering the temperature of the brain in order to reduce damage caused by conditions such as stroke, traumatic brain injury, and cardiac arrest. This cooling process can help to slow down metabolic processes and reduce inflammation, ultimately protecting the brain from potential harm. The goal of brain cooling is to preserve brain function and improve outcomes for patients with neurological injuries or conditions. Many hospitals and medical centers now use brain cooling as a standard treatment for certain neurological emergencies.
