High levels of stress can negatively affect physical health by increasing the risk of various medical conditions, such as heart disease and obesity. Chronic stress triggers the release of hormones like cortisol, which can lead to unhealthy behaviors such as overeating or sedentary lifestyles, contributing to weight gain and metabolic issues. Additionally, prolonged stress can weaken the immune system, making individuals more susceptible to illnesses. Addressing stress through healthy coping mechanisms, such as exercise, relaxation techniques, and social support, is essential in promoting long-term physical health.
