physiological response to heat

When your body gets too hot, it activates mechanisms to cool down. Blood vessels near the skin widen, allowing more blood to flow and release heat. Sweat glands produce sweat, which evaporates and helps lower body temperature. These responses work together to maintain a healthy internal temperature, preventing heat-related illnesses. If the body can't cool down effectively, core temperature rises, leading to fatigue, dizziness, or more serious conditions like heat stroke. Staying hydrated and in a cool environment supports these natural cooling processes.
