What Is Stress ?
Stress is not mental tension. Stress is burden on your body and mind. When it is within your capacity, it improves your system. You feel energetic. When it outgrows your capacity, you feel tired and weak. Burden could be physical, like working day and night without rest. Or it could be financial burden. An impending wedding or hospitalization can be a cause of your stress. If you are hiding something in the mind for a long time, it becomes a cause of your stress.
Work related stress is usually overworking beyond 8 hours. Continuous focussing on job cause mental fatigue. Young persons don't feel it. So they overlook it and continue working. Initial first symptoms could be heartburn, indigestion, headache, bodyache or infections. Later you have high blood pressure, kidney stone, gout, skin diseases. Still later thyroid, diabetes, pcod, liver disease raise their head.
Stress is the root cause. If it is not treated, your disease will keep on increasing and your dependence on medicine will continue.
