 Hello everyone. I am Sira Satish Kumar, consultant clinical psychologist in the Department of Psychiatry in Manipal Hospital, Spangler. Yes, there are plenty of research. Welfare of knowledge from the research background has shown that stress brings in autonomic hyperactivity. Which simply means when a person is under stress, person experiences short-term and long-term stress symptoms which are like increased heart rate, dryness of the palms, dryness of the throat, gastritis and many other short-term and long-term effects like disturbed sleep. So when this is being prolonged, it so happens that different neurotransmitters, different hormonal imbalances happens in the body where there are different short-term and long-term symptoms that is seen and when it becomes chronic, a person starts developing terminal illnesses, even cancer. At the most people experience various coronary diseases, diabetes and hypertension has become the most common disorder associated with the stress.
