Stress is the body's natural response to any demand or challenge, triggering a physical, emotional, or mental reaction. It often arises when people perceive a situation as overwhelming or beyond their ability to cope. Stress can be caused by various factors, such as work pressure, personal relationships, or environmental changes. In small doses, stress can motivate individuals to take action or solve problems. However, chronic or excessive stress disrupts the body’s balance, leading to negative effects that can impact overall health and well-being.

Prolonged stress has significant effects on both the body and mind. Physically, it activates the body's "fight or flight" response, releasing hormones like cortisol and adrenaline, which, over time, can strain the cardiovascular system, weaken the immune response, and cause digestive issues. Mentally, chronic stress contributes to anxiety, depression, memory loss, and poor concentration. It can also lead to emotional instability, increased irritability, and fatigue, making it difficult to manage daily life. Understanding these impacts is crucial in learning how to reduce stress and maintain a healthy, balanced lifestyle.
