The Science of Stress

Explanation of the body’s stress response

Stress activates the body’s stress response, also known as the “fight or flight response.” In response to stress, the body releases stress hormones such as cortisol and adrenaline, which help prepare the body to respond quickly to challenges.

The role of hormones such as cortisol and adrenaline

Cortisol and adrenaline play an essential role in the stress response by increasing blood pressure, heart rate, and breathing rate. Cortisol also regulates the body’s immune response and metabolism.

The difference between acute and chronic stress

Acute stress is short-term stress that our body experiences in response to a specific event, while chronic stress is ongoing stress that persists over a prolonged period.
