Stress can significantly impact physical health, leading to a variety of negative effects, including decreased immune function, increased risk of chronic diseases, and mental health issues like anxiety and depression. Chronic stress can elevate cortisol levels, which, when prolonged, negatively affects metabolism and muscle function. It can also result in sleep disturbances, fatigue, and changes in appetite, ultimately undermining both physical and mental well-being. Therefore, effective stress management is important for maintaining overall health.
