Stress includes physical, emotional and intellectual responses of human body towards any changes or challenges. These responses are normal and help a human body to adapt to new situations. A positive stress can help your body to work harder with an improved performance. Stress becomes unhealthy when it upsets your day to day functioning and there is no period of relaxation or relief in between.        

Physical symptoms may include headaches, dizziness, exhaustion, aches, chest pain, high blood pressure, gastrointestinal issues, muscle tension and a weak immune system.
