When we're under pressure, our bodies react in different ways. These alterations are designed to aid the body in its defense against the perceived threat. However, chronic stress can have negative effects on one's health. The risk of cardiovascular illnesses is significantly elevated in people who are under persistent stress. Hormones released in response to stress can increase blood pressure and cholesterol, both of which are risk factors for cardiovascular disease. In addition, the immune system is further compromised by prolonged stress, increasing the likelihood of disease and infection.
