Summary: The text discusses the impact of stress on our bodies and how it can lead to chronic diseases such as heart disease and diabetes. Stress triggers various biological responses in our bodies, including the release of hormones like cortisol and adrenaline, which can contribute to inflammation and high blood pressure. Chronic stress can also affect our behavior, leading to unhealthy habits like overeating, smoking, or excessive drinking. It can also disrupt sleep patterns and weaken our immune system, making us more vulnerable to illnesses. Managing stress through techniques like exercise, meditation, and social support can help reduce its negative effects on our health and overall well-being.
