Chronic stress can manifest in physical symptoms such as headaches, muscle tension, fatigue, and gastrointestinal issues. Prolonged stress activates the body's fight or flight response, leading to elevated levels of cortisol and adrenaline. This hormonal imbalance can contribute to muscle tightness, increased blood pressure, and compromised immune function. Other manifestations may include weight gain, sleep disturbances, and chronic fatigue. Recognizing these physical symptoms as signals of chronic stress is critical in implementing effective stress management techniques to maintain both mental and physical health.
