2. Stress and Its Invisible Chains

Stress is an insidious factor that can severely disrupt sleep patterns. Chronic stress leads to elevated levels of cortisol, a hormone that can interfere with the sleep cycle. The body's natural rhythm is thrown off balance, making it difficult to fall and stay asleep. Even if sleep is achieved, the mind may remain active, preventing deep, restorative rest. Techniques like mindfulness, meditation, and cognitive behavioral therapy can help manage stress levels, potentially improving sleep quality and reducing fatigue.
