Exposure to stress can have significant negative impacts on both mental and physical health. Prolonged or chronic stress can weaken the immune system over time and increase risks of illnesses. Health psychologists study the relationships between psychological factors like stress and the body's systems. While short-term stress can stimulate aspects like creativity, long-term stress is generally harmful and can lead to issues like adjustment disorders or post-traumatic stress disorder. Managing stress through techniques such as exercise, social support, and relaxation can help reduce risks to health.
