Stress is a feeling of emotional or physical tension. It can come from any event or thought that makes you feel frustrated, angry, or nervous. Stress is your body's reaction to a challenge or demand. In short bursts, stress can be positive, such as when it helps you avoid danger or meet a deadline.
Stress is key for survival, but too much stress can be detrimental. Emotional stress that stays around for weeks or months can weaken the immune system and cause high blood pressure, fatigue, depression, anxiety and even heart disease. In particular, too much epinephrine can be harmful to your heart.
