Chronic stress adversely impacts physical health by activating the body's stress response, leading to various health issues. Prolonged stress can elevate levels of the hormone cortisol, which is associated with increased blood pressure, weight gain, and a weakened immune system. Additionally, chronic stress can exacerbate existing health conditions, such as heart disease and gastrointestinal disorders. It may also lead to unhealthy coping mechanisms like overeating or substance abuse, further compounding health problems. Managing stress is essential for maintaining overall health and well-being.
