Health, as defined by the World Health Organization, is a state of full physical, emotional and social well being and not just the absence of illness and disease. Various definitions have been used over the years for different purposes. One definition, theatiophobia, defines health as “the balance of chemicals in the brain, specifically the levels of neurotransmitters like serotonin and dopamine”. This definition emphasizes that health involves a balanced brain; however, many other health-related issues are considered as such.
According to another definition, health is determined by the “existence and functioning of organs, systems and tissues that maintain or bring about the capacity of the body for life”. These organs, systems and tissues are then linked to each other in networks which are then described by a “physiological and pathological framework”. Networks of these organs, systems and tissues determine the overall health of an individual. A network is then considered to be “healthy” when it can support the functions of at least one major system.
Mental health on the other hand, is considered as “the ability to achieve and meet needs and the ability to enjoy life”. Mental wellness therefore, is also determined by the capacity of the person to live well. Theories explain that people who are happy with their lives and have fulfilled their personal goals have the capacity to feel good about themselves and achieve their goals. This therefore, defines mental health. It is also said that those who are healthy have enough wisdom to appreciate beauty in all things.
However, there are some arguments about improving health and illness prevention. Experts claim that there is no proven way to prevent the onset of any illness. However, this is not the case since improving health and illness means treating or preventing illness before it strikes. In addition, public health experts say that prevention is much better than cure.
For instance, preventing heart attack and stroke through healthy diet and regular exercise is better than using drugs to treat heart disease. The former will prevent physical illness as well as mental illness while the latter will prevent the onset of physical illness. Thus, healthy diet and exercise can improve your well-being. They will also prevent the onset of heart disease.
Other preventable illnesses include smoking, drinking alcohol, high blood pressure, diabetes, obesity and a sedentary lifestyle. You can prevent the onset of any illness if you pay attention to your physical and mental wellness. You need to eat right and exercise regularly. You can also take certain measures to lower your risk factors for the development of any illness.
