Is a steroid hormone that is produced by the adrenal glands. It is commonly known as the “stress hormone” because it is released in response to stress and low blood-glucose concentration. It plays a crucial role in the body’s stress response, also known as the “fight or flight” response.
Cortisol has many functions in the body, including:
- Regulating blood sugar levels: Cortisol helps to increase blood sugar levels by breaking down stored carbohydrates, proteins, and fats into glucose.
- Regulating blood pressure: Cortisol causes the blood vessels to constrict, which increases blood pressure.
- Modulating the immune system: Cortisol suppresses the immune system, which can be beneficial during times of stress, when the body needs to redirect energy away from the immune system to more pressing needs.
