Chronic stress can have several detrimental effects on the body, including increased production of cortisol, which can lead to weight gain, particularly around the abdomen. It may also contribute to cardiovascular issues, such as hypertension and increased heart rate, as well as muscle tension and pain. Furthermore, prolonged stress can weaken the immune system, making individuals more susceptible to illnesses. Over time, chronic stress can impair mental function, leading to anxiety and depression, highlighting the importance of managing stress for overall health and well-being.
