And, instead of the threat going away, today's stressors often remain for months or years. Our brain does not give our bodies the all clear sign to remove the chemicals that caused the initial stress response. Instead many of us are faced with constant stress that can lead to health problems. Eventually our bodies react to chronic stress with a number of symptoms including headache, stiff neck, nagging backache, rapid breathing, sweaty palms, an upset stomach, emotional irritability, feeling exhausted, or an inability to concentrate. Chronic stress, if not relieved, can cause high blood pressure, cardiac problems, digestive problems, and changes in the immune system such as susceptibility to colds and flu, asthma attacks, and skin conditions.
Some people deal with stress by smoking, eating more, drinking alcohol, or by using drugs.
Of course all of these are unhealthy ways of dealing with stress. One of the most beneficial stress reducers is exercising regularly.
