Heatstroke happens when your internal thermostat fails, causing your core body temperature to spike above 104 degrees Fahrenheit (40 degrees Celsius). It affects your entire body, particularly your brain, heart, kidneys, and muscles, as the intense heat begins to damage your internal organs.
This occurs when you are exposed to extreme heat or physical activity for too long and your body loses its ability to get rid of that extra heat through sweating. It is a true medical emergency that requires immediate help to prevent permanent damage.
