Stress and anxiety can adversely affect physical health by contributing to various chronic conditions. Chronic stress often leads to increased levels of cortisol, which can result in weight gain, high blood pressure, and an increased risk of heart disease. Anxiety can cause tension in muscles, contributing to headaches and other physical discomforts. Additionally, stress may lead to poor lifestyle choices, such as unhealthy eating and reduced physical activity. Recognizing and managing stress through techniques like mindfulness, exercise, or therapy can significantly improve overall health.
