Health psychology is a kind of science that helps us understand how our minds and bodies work together to keep us feeling healthy and happy. It looks at how physical and mental health are connected and how our thoughts, emotions, and behaviours impact how we look after our bodies, minds, and overall health. By understanding how the two areas (physical and mental health) can affect one another, health psychologists help us figure out how to take better care of ourselves and help us learn skills to manage stress and stay happier and healthier.
