How long can the effects of sunstroke last?

Sunstroke, also known as heatstroke, is a medical emergency that occurs when the body's temperature rises rapidly, usually as a result of exposure to high temperatures. The effects of sunstroke can last for days or even weeks and may include fatigue, irritability, difficulty concentrating, dizziness, headaches, sleep disturbances, muscle cramps, nausea, vomiting, dehydration, and electrolyte imbalances. In some cases, sunstroke can lead to permanent brain damage, kidney failure, heart failure, and even death. It is important to recognize the signs and symptoms of sunstroke and seek immediate medical attention if you suspect someone is experiencing this condition.
