A life without any challenge or pressure, i.e., “stress,” would be under stimulating and deadly boring. Everyone needs a certain amount of “pressure” to perform at their best. But when the pressures exceed a person’s ability to cope, the result is stress. And, prolonged stress can set up a cycle of distress and cut down the ability to cope with ordinary situations too. Illnesses believed to be caused by stress, if only in part, include angina, asthma, cancer, cystitis, depression, diabetes, diarrheas, heart attack, migraine, psoriasis rheumatoid arthritis, and ulcers. Partial loss of body hair (alopecia areata) or even total loss of all body hair (alopecia universalis) can also result from stress.
