Health is a condition of total physical, mental and emotional well-being where infirmity and disease are absent. A healthy person usually feels fresh, lively and physically fit for a short period of time after coming into contact with the elements. The first five senses (sense of smell, taste, touch, and hearing) are most sensitive to changes in health. Mental health is influenced by the quality of relationships we have, how we perceive our environment, what we learn, and what we are exposed to on a daily basis.
It is estimated that up to one third of all adults globally suffer from a mental health issue at some point in their lives. The most common of these issues are depression, anxiety, stress, panic attacks, bipolar disorder, eating disorders, drug and alcohol abuse and violence. Mental health care can be quite expensive, but many other health issues can also arise due to a poor diet, sedentary lifestyle and lack of exercise. A good diet, exercise, and good communication with your doctor can go a long way towards ensuring optimum health. There are also some simple steps you can take to improve your well-being.
The prevention of health problems varies widely according to culture, age, gender, and locality, as is evident in the different approaches to addressing the issue of smoking and obesity. The main areas of concern in public health include nutrition, general health, cardiovascular health, infant and child health, occupational health, and substance abuse and dependence. Public health aims to ensure all the segments of society are healthy through a system of primary care and preventive care. Prevention of chronic diseases such as diabetes, hypertension, and osteoporosis helps to reduce medical bills. It also improves the quality of life and reduces the risk of various other chronic health problems.
Prevention of communicable diseases such as diarrhea, measles, cholera, typhoid, and viral hepatitis is an important aspect of this field. An integrated communicable disease management system is designed to address all the aspects of the problem such as identification, evaluation, treatment, and control. These systems have been developed through decades of research and trials, and are very successful in containing and controlling communicable diseases. These include dysentery, diarrhea, SARS, measles, and genital herpes.
Maintaining a good health status is also crucial in preventing the occurrence and recurrence of diseases. Healthy lifestyle practices such as regular exercise and diet, and the modification of food and beverage consumption, can play a vital role in maintaining good health. Smoking cessation, weight loss, and diets that lower the risks of certain kinds of cancer are also important. Regular screenings for high blood pressure, diabetes, and heart disease help to prevent heart attacks and strokes. Other preventive measures include vaccinations and checkups, as well as immunizations against diseases such as HIV/AIDS.
Health promotion means encouraging a healthy lifestyle by practicing a balanced diet, physical activity, and a healthy lifestyle. It also includes promoting social well-being by encouraging friends and family to practice a balanced diet and to get regular physical activity. Family counseling and family therapy can also play a vital role in this direction. Health promotion programs should take into account the special needs of individuals living in a developing country, providing them with access to quality health services and promoting social well-being by supporting healthy lifestyles and community-based care.
