Soldiers may also elect not to wear a combat patch. Controversies have arisen in recent years over brigade commanders' decisions to ban combat patches in certain situations. This has been done in an effort to make new recruits, who didn't have the patches, feel less excluded.
Cortisol and Stress: How Cortisol Levels Affect the Body. Cortisol and stress are connected and, although stress isn't the only reason for the release of cortisol into the blood stream, it is still known as a stress hormone. Every time that you are confronted with a stressful situation your body undergoes a fight or flight response and cortisol levels increase.
Your bodyâs response to stress is supposed to protect you. But, if it is constant, it can harm you. The hormone cortisol is released in response to stress. Studies suggest that the high levels of cortisol from long-term stress can increase blood cholesterol, triglycerides, and blood pressure. These are common risk factors for heart disease. This stress can also cause changes that promote the buildup of plaque deposits in the arteries.
