The three main stress hormones are cortisol, epinephrine (adrenaline), and norepinephrine. These hormones are released during times of stress to help the body cope with a perceived threat.
- Cortisol, the primary stress hormone, is produced by the adrenal glands. It increases blood sugar levels, suppresses the immune system, and promotes the breakdown of muscle tissue.
- Epinephrine and norepinephrine are catecholamines that are also produced by the adrenal glands. They are responsible for the "fight or flight" response, which includes increased heart rate, blood pressure, and alertness.
These hormones play a crucial role in the body's stress response, but chronic exposure to high levels of stress hormones can have negative effects on health.
