Stress is a natural response of the body to challenges or demands, often referred to as a "fight or flight" reaction. It can be triggered by various factors, including work pressures, personal relationships, or major life changes. While some stress can be beneficial, helping individuals stay focused and motivated, excessive stress can lead to negative health effects. Chronic stress can impact both mental and physical well-being, contributing to issues such as anxiety, depression, and heart disease. Managing stress through techniques like exercise, mindfulness, and proper time management can help improve overall health and quality of life.
