Stress Kills
Modern life is full of pressure, stress and frustration. Worrying about your job security, being overworked, driving in rush-hour traffic, arguing with your spouse — all these create stress.
According to a recent survey by the American Psychology Association, fifty-four percent of Americans are concerned about the level of stress in their everyday lives and two-thirds of Americans say they are likely to seek help for stress.
You may feel physical stress as the result of too much to do, not enough sleep, a poor diet or the effects of an illness. Stress can also be mental: when you worry about money, a loved one's illness, retirement, or experience an emotionally devastating event, such as the death of a spouse or being fired from work. However, much of our stress comes from less dramatic everyday responsibilities. Regardless of the source, stress has a tremendous impact on your overall health.
When you experience stress, your pituitary gland responds by increasing the release of a hormone called adrenocorticotropic hormone (ACTH). When the pituitary sends out this burst of ACTH, it's like an alarm system going off deep inside your brain. This alarm tells your adrenal glands, situated atop your kidneys, to release a flood of stress hormones into your bloodstream, including cortisol and adrenaline. These stress hormones cause a whole series of physiological changes in your body, such as increasing your heart rate and blood pressure, shutting down your digestive system and altering your immune system.

- A long-term activation of the stress-response system can disrupt almost all your body's processes. Some of the most common physical responses to chronic stress are:
- Digestive system. Stomach aches or diarrhea are very common when you're stressed. This happens because stress hormones slow the release of stomach acid and the emptying of the stomach. The same hormones also stimulate the colon, which speeds the passage of its contents.
- Immune system. Chronic stress tends to dampen your immune system, making you more susceptible to colds and other infections. Typically, your immune system responds to infection by releasing several substances that cause inflammation. Chronic systemic inflammation contributes to the development of many degenerative diseases.
- Nervous system. Stress has been linked with depression, anxiety, panic attacks and dementia. Over time, the chronic release of cortisol can cause damage to several structures in the brain. Excessive amounts of cortisol can also cause sleep disturbances and a loss of sex drive.
- Cardiovascular system. As mentioned earlier, stress causes an increase in both heart rate and blood pressure and increases the risk of heart attacks and strokes.
