Acute stress reaction

Acute stress reaction is how your body and mind respond to feeling worried, scared, or overwhelmed. Stress reaction is like a safety alarm in your body. When your body notices something worrisome or overwhelming, it releases chemicals in your brain that make you feel alert or scared. This is to prepare your body to react to the situation, like if you had to run quickly away from something dangerous.
