Cortisol is known as the stress hormone, since one of its most important actions is managing situations of alert or threat to the body. However, even without stress, the hormone is constantly present, regulating different bodily functions: it regulates metabolism, the use of fats, proteins and carbohydrates, reduces inflammation, which is also essential in stressful situations such as injury or accident, controls blood pressure and blood glucose levels, regulates sleep cycles and helps to create energy peaks.
