Cortisol influences the whole body

Because most cells have cortisol receptors, this hormone can influence nearly every system in the body: from energy and metabolism to immunity and cognitive function.

Cortisol levels change rapidly

Cortisol is a highly dynamic hormone that responds quickly to emotional and environmental cues. Even a brief stressor, such as public speaking, can increase cortisol levels by around 60% above baseline, reflecting the body’s immediate stress response.

Cortisol levels can drop rapidly in response to calming signals. Even 10 minutes of gentle interaction with a dog or cat has been shown to significantly lower cortisol levels.
