Stress is both additive and cumulative. It adds up over time until a state of crisis is reached and symptoms appear. So, even when a series of little things happen which make you anxious and nervous, can, over a period of time, be harmful. Stress can make you susceptible to colds, respiratory disorders, and even tooth decay. It can also increase your risk for developing heart disease, high blood pressure, diabetes, asthma, ulcers, colitis, and cancer.
