Your health is powerfully affected by what you think and feel.
There is some evidence that the immune system may be weaker in hostile people. According to a study of more than 1,000 people at a Western Electric factory in Chicago over a 25-year period, those with high hostility scores were at a high risk of dying not only from coronary disease but from cancer as well.

• According to the American College of Cardiology, sudden cardiac death accounts for 400,000 deaths each year in the United States.
• In 2009 a group from Yale University studied 62 patients with heart disease and implantable defibrillators that detect dangerous heart arrhythmias and deliver an electrical shock to restore a normal heart beat. The subjects were put through an exercise in which the patient recounted a recent angry episode while the electrical activity of the heart was measured. The study found that
anger increased electrical instability
of these patients. The study followed these patients for three years and suggests that anger impacts the heart’s electrical system
in ways that can lead to sudden death

• A study of men found those “generally hostile and contemptuous of other people” are
30 percent more likely to develop a heart condition
called atrial fibrillation—a “flutter” that signals an
increased risk of stroke
.

• Increased heart rate and blood pressure when a person is angry cause “micro-tears” in the lining of the arteries, making it
easier for blockages to form
.

• A study begun in 1983 concluded that medical students with high “hostility” levels while in school were
seven times more likely to die before age 50
—of any cause—than their calmer peers.

• People who already suffer from heart disease nearly
triple their risk of a heart attack
when they become extremely angry. The increased vulnerability lasts for at least two hours.

• A survey of nearly 2,500 emergency room patients who had been injured in some way found that “people who described themselves as feeling irritable have a 30% increased risk for getting injured, while those who are feeling hostile
double their risk of injury
.”

• Epinephrine (adrenaline) is released by the adrenal glands,

immediately preparing the body for a fight-or-flight response. However, if fight or flight does not occur, the highly energized body has difficulty calming down. (This is why angry people experience a racing heart, shaking hands, and fast breathing.)
• The angry person’s hormones then travel from the brain to the adrenal glands, signaling the need for tension reduction by the release of cortisol. However, cortisol raises blood pressure above the norm, which makes
rational thinking more difficult.
