Preventing Disease

Health psychologists promote health and they hope that it will prevent disease. Many chronic disorders, such as heart disease, lung disease, cancer, and complications from substance abuse, have continued to rise in the second half of the twentieth century, even with all the new technology. These illnesses are the leading causes of death in the United States.

Health psychologists have found that many of these chronic illnesses could have been prevented through modifications in behavior. For example, approximately 25% of all cancer deaths and 350,000 heart attack deaths could be avoided annually through the cessation of smoking alone. There is also poor diet and lack of exercise that contribute to the onset of many disorders. Health psychologists want to find out why people still smoke when they know it causes cancer.
