Cortisol: What Are the Symptoms of High Cortisol?
Feeling constantly stressed, wired, tired, or unable to switch off?
For some people, these experiences may sometimes feel linked to high cortisol levels.
Cortisol is often called the body’s main stress hormone because it helps regulate energy, alertness, metabolism, sleep, and the body's stress response.
In short bursts, cortisol plays an important role in helping the body respond to pressure.
However, when stress feels ongoing, cortisol may sometimes stay elevated for longer periods, which may affect how people feel day to day.
This guide explains what cortisol is, common symptoms of high cortisol, possible causes, and supportive habits that may help restore balance.
What Is Cortisol?
Cortisol is a hormone produced by the adrenal glands.
It helps support:
- Energy regulation
- Stress response
- Sleep-wake cycles
- Metabolism
- Blood sugar balance
- Immune system function
Cortisol naturally rises in the morning to help you wake up and usually lowers in the evening to support sleep.
However, modern lifestyle factors may sometimes affect this rhythm.
