This document discusses heat stroke, including its causes, symptoms, complications, treatment and homeopathic approaches. Heat stroke occurs when the core body temperature exceeds 40.6 degrees Celsius due to overexposure to heat. It can be life-threatening without prompt treatment to lower the core temperature. Common causes are high environmental heat/humidity, strenuous exercise, and underlying medical conditions. Symptoms include hot dry skin, headache, confusion and loss of consciousness. Treatment involves rapid cooling through cold water immersion or ice packs. Homeopathic remedies aim to restore the individual's vital energy pattern based on their total set of symptoms.
