Health Exercise and Activity Therapy (HEAT) is an Institution that provides evidence-based and tailored lifestyle interventions for healthy and disease populations, promoting physical activity and reducing sedentary behaviours. Importantly, we also develop interventions that help adherence to such improved lifestyles. Our approach is based on state-of-the-art research provided by the most recent guidelines of the World Health Organisation (WHO) and the National Institute for Health and Care Excellence (NICE). The senior members of HEAT are high profile academics, clinicians and governmental scientists that support HEATs mission with genuine care for the individual and the community. Our research so far has had a significant impact national and internationally and has helped change guidelines for diseased population as well as helping raising awareness for the benefits of lifestyle change.
