Stress First Aid: Part 1 – Recognizing Stress and Stress Reactions

When your body senses danger, it activates the body’s sympathetic nervous system (SNS) to help maintain homeostasis (stability when adapting to change). This system also helps prepare you to handle the danger, whether real or perceived.2
The SNS is involved in the body’s stress response. It releases the stress hormones adrenaline and cortisol to help with the “fight or flight” response. When the acute stress is over, the parasympathetic nervous system (PNS) helps your body return to its normal state.3
