Health, according to the World Health Organization, is a condition that “consists of the status or condition of a human being that is normal in its features but at the same time causes harm to the body when the normal conditions are disturbed.” A number of definitions have also been applied to health, over time. For instance, physical well-being is considered a state of health if “all the major systems of the body are functioning well, and there are no apparent signs of any disorder.” The definition of health is also considered as the basis for the concept of medical management, which aims to promote health by providing means to prevent, treat and control diseases. This also includes preventing, diagnosing, and treating diseases and injuries that may occur during a person’s lifetime.
Good health is not only about having a good body structure or healthy organs; it also has to do with one’s attitude and behavior, as well as their experiences and environment, such as the quality of water, sanitation, and other public services. People who suffer from ill health conditions are more susceptible to infectious diseases. Illness may result to physical ailments, psychological disorders, and environmental factors like toxins, pollution, and radiation. Stress, fatigue, and lack of sleep can also result to poor health. Poor well-being is the result of poor nutrition, physical activity, and unhealthy lifestyle, all of which may lead to serious illness.
To sum up, there are different types of definition for health, ranging from the most strict to the most flexible, from life expectancy to physical activity. The most important goal in defining health is to maintain health, which may include well-being, physical and mental health, as well as the prevention of diseases and injury. In order to achieve well-being, people need to maintain a healthy lifestyle by choosing foods and activities that they enjoy, exercising regularly, and avoiding risky or hazardous practices, such as excessive smoking and drinking. This healthy lifestyle may not be effective for everyone, but it will certainly help many people to get better physical health.
