Acute stress response

The acute stress response is your body's immediate reaction to a perceived threat or danger. When faced with a stressful situation, your brain signals the release of hormones like adrenaline and cortisol. These hormones prepare your body to respond quickly—your heart races, muscles tighten, and senses become sharper—giving you extra energy and focus to handle the threat. Once the danger passes, hormone levels drop, and your body returns to normal. This response is a natural survival mechanism, helping you react effectively in urgent situations.
