Community psychologists are particularly skilled and experienced at fostering community participation and empowering consumers to make fully informed health decisions. The involvement of consumers in decisions that impact on their health, including how and what health services are provided, is now recognized as key to ensuring relevant and accessible services, and enhancing the health system's ability to respond to emerging health challenges. Psychology as the science of behavior and mental processes emphasizes training and knowledge about such aspects (e.g. development over the lifespan, learning, motivations, experiences, emotions, cognition, social behavior and attitudes, personality, etc.). Moreover, it strives to understand how biological, behavioral, and social factors influence health and illness. (Scott, & Wolfe, 2015).

Thus, psychologists as behavioral health providers play a major role in understanding how biological, behavioral, and social factors influence health and illness. They are equipped with training, skills, and knowledge to understand how basic behavioral and cognitive processes (e.g., cognition. emotion, motivation, development, personality, social and cultural interaction) prepare the body to develop dysfunctions. They are trained, on the other hand, to perceive how these behavioral and cognitive functions are altered, the factors that contribute to their alteration, and how these dysfunctions are diagnosed and treated. In dealing with such problems, they are also trained and skilled to use several psychological, psychodiagnostic, and psychotherapeutic techniques which help and affect the abilities of individuals to function in diverse settings and roles. In addition, they help people to modify their behavior and lifestyle so as to prevent and recover from health problems. (Wahass, 2005).

Health psychology (sometimes referred to as medical psychology or behavioral medicine) can be defined as the aggregate of the specific educational, scientific, and professional contributions of the discipline of psychology to the promotion and maintenance of health, the prevention and treatment of illness, the identification of etiological and diagnostic correlates of health, illness, and related dysfunction, and the improvement of the health care system and health policy formation. Sustainability topics are a natural fit with related themes in psychology such as global warming, ethics, and practitioners who conduct and apply research and advance theory to improve interactions between humans and our natural and built environments. natural fit because it allows a better understanding of one's personality and behavior. The understanding of humanity would open doors to a complex and progressive society. This can also improve perspective, mental stability, and not just physical health but also psychological health. This might seem silly, but it becomes important because those simple sentences of our internal dialogue [self-talk] allow us to find psychological issues. The content of our internal dialogue is often terribly illogical, irrational, inaccurate, invalid, and faulty. (Wahass, 2005).

There are health psychologists who focus on that aspect and we are not always trained for the issues of behavioral health.

How are we involved in those areas?
