What is cortets?

As an AI language model, I assume you meant "cortisol".

Cortisol is a hormone that is produced by the adrenal gland in response to stress. It helps the body to deal with stress by increasing blood sugar levels and suppressing the immune system. Cortisol also plays a role in the regulation of the sleep-wake cycle, and in the metabolism of fat, protein, and carbohydrates.

Chronically elevated cortisol levels can have negative effects on the body, including weight gain, high blood pressure, and an increased risk of heart disease. Prolonged stress and poor sleep habits are two factors that can lead to elevated cortisol levels.

Cortisol levels can be measured with a simple blood test, and treatment for elevated levels may include stress reduction techniques, dietary changes, and medication. It is important to work with a healthcare provider to determine the cause of elevated cortisol levels and develop a treatment plan.
