Health knowledge is an important but not sufficient factor in order to provoke a behavioral change toward a healthier life style. Knowing that something is beneficial or a risk to your health and perceiving it as a chance or threat are not the same. Schwarzer proposes the Health Action Process Approach for helping to bridge the know - do gap underlining the importance of adoption, initiation, and maintenance of health behaviors conceived of as a structured process including a motivation phase and a volition phase. The proposed study fosters acquisition and maintenance of health behaviors like activity in form of amount of steps performed during a day, sleeping behavior and monitoring of the heart rate.
