The human body is designed to experience stress and react to it. Stress can be positive, keeping you alert and ready to avoid danger. Stress becomes negative when a person faces continuous challenges without relief or relaxation between challenges. As a result, the person becomes overworked, and stress-related tension builds.
Stress that continues without relief can lead to a condition called distress, a negative stress reaction.
Distress can lead to physical problems including headaches, upset stomach, elevated blood pressure, chest pain and trouble sleeping. Research suggests that stress can also bring on or worsen certain symptoms or diseases.
