Body Temperature Regulation

Body temperature regulation, or thermoregulation, is how your body maintains a stable internal temperature around 98.6°F (37°C). It does this through the brain's hypothalamus, which senses temperature changes. When you're too hot, your body releases sweat and increases blood flow to your skin to cool down. When you're cold, it causes shivering and constricts blood vessels to conserve heat. These mechanisms work together automatically to keep your body within a healthy temperature range, ensuring your organs function properly despite external conditions.
