Health Psychology Lecture Note

Health psychology examines how biological, social and psychological factors influence health and illness. Health psychologists use psychological science to promote health, prevent illness and improve health care systems.

For years, we’ve known about the dangers of smoking, and that we should eat less and move more. But in the end, what motivates us to put down the doughnut and hit the running trail or carefully follow a doctor’s instructions about medications and follow-up visits?

Health psychology explores those motivations in the pursuit of getting people to embrace health promotion and illness prevention. This specialty area examines how biological, social and psychological factors influence the choices we make about our health.

Health psychologists study the factors that allow people to be healthy, recover from an illness or cope with a chronic condition. They are experts in the intersection of health and behavior and are in demand as a part of integrated health care delivery teams — working with other doctors to provide whole-person health care.
