Cortisol and Anxiety. Cortisol is our number one stress hormone that plays a huge role in regulating a variety of different processes in the human body. From helping you fight an infection or deal with an injury to giving you a boost of energy to run from immediate danger and focus in times of crisis.
Even though our cortisol levels change throughout the day, they are supposed to be the highest in the morning when we wake up and gradually decrease throughout the day. If there’s an event or a stressful situation occurring at 3 pm, it’s naturally going to spike, but it should be followed by a natural decline.
