what is cortisol?
Cortisol hormone popularly referred to as stress hormone, is a steroid hormone that is produced by the adrenal glands located on top of each kidney. Cortisol is mainly released in response to stress and low blood glucose concentration. Cortisol hormone belongs to the glucocorticoid class of hormones.

Generally, cortisol levels are at their highest level in the morning which drops down to the lowest level by evening.
functions of cortisol
Cortisol is a steroid based hormone and is a strong chemical that modifies the gene activity in the DNA. It prompts the cells to produce glucose from proteins and fatty acids, a process known as gluconeogenesis. This saves the glucose for the brain, forcing the body to use fatty acids from the stored fat as energy. Some of its main functions includes the following;
- Cortisol hormone manages how the body utilises carbohydrates, protein and fats in the body.

- Regulates blood pressure
- Increases blood sugar or glucose
- Controls the sleep – wake cycle
- Cortisol gives energy boost to deal with stress and restores balance later.
