The focus of public health interventions is to prevent and manage diseases, injuries and other health conditions through surveillance of cases and the promotion of healthy behavior, communities, and (in aspects relevant to human health) environments. Its aim is to prevent health problems from happening or re-occurring by implementing educational programs, developing policies, administering services and conducting research.[49] In many cases, treating a disease or controlling a pathogen can be vital to preventing it in others, such as during an outbreak. Vaccination programs and distribution of condoms to prevent the spread of communicable diseases are examples of common preventive public health measures, as are educational campaigns to promote vaccination and the use of condoms (including overcoming resistance to such).

As the number of service sector jobs has risen in developed countries, more and more jobs have become sedentary, presenting a different array of health problems than those associated with manufacturing and the primary sector. Contemporary problems, such as the growing rate of obesity and issues relating to stress and overwork in many countries, have further complicated the interaction between work and health.

The environment is often cited as an important factor influencing the health status of individuals. This includes characteristics of the natural environment, the built environment and the social environment. Factors such as clean water and air, adequate housing, and safe communities and roads all have been found to contribute to good health, especially to the health of infants and children.[13][24] Some studies have shown that a lack of neighborhood recreational spaces including natural environment leads to lower levels of personal satisfaction and higher levels of obesity, linked to lower overall health and well being.[25] It has been demonstrated that increased time spent in natural environments is associated with improved self-reported health [26], suggesting that the positive health benefits of natural space in urban neighborhoods should be taken into account in public policy and land use.
Sleep and meditation. Try to avoid high intensity exercising like running and weight-lifting. The more your body is working, the more energy you'll lose. Take the time to relax, stretch (keeps your blood circulation to better remove toxins), and use the time to reflect. Ask yourself why you're doing this, and empower your will to finish. Drink lots of water, nap, and go to bed early. Avoid watching TV because it'll disrupt your consciousness and make you hungry (due to all the food commercials).
