Straining, or stress, refers to the body's response to external pressures or demands. It can occur due to various factors, including work, relationships, or financial issues. When faced with stress, the body releases hormones like cortisol and adrenaline, which prepare it for a "fight or flight" response. Chronic stress can lead to negative health effects, such as anxiety, depression, and physical ailments like high blood pressure or heart disease. Managing stress through techniques like exercise, meditation, or time management can help improve overall well-being and reduce its impact on daily life.
