Impact the World Through Public Health

Today’s medical advances are allowing people to live longer. Although there are fewer deaths from cancer and heart disease, more people are living with chronic illnesses. Citizens of the united states as a whole are showing troubling levels of obesity, high blood pressure and diabetes. We may be living longer, but we are sicker. Public health refers to the science and art of preventing disease, prolonging life and promoting human health. Those that choose to study public health enter a field where their thoughts and actions can have a real impact their surrounding communities and beyond.

Importance of Public Health

Public health initiatives affect people in their everyday lives in every part of the world. Professionals address issues affecting the health and well-being of individuals, communities, societies, states, countries and populations. It is about not only keeping people alive but allowing them to thrive. Public health programs can lead to longer life expectancies, reduction in infant mortalities and eradication of communicable diseases. These sound like pipe dreams, but they don’t have to be. Increasing life expectancy is about more than health care initiatives, although it encompasses that as well. Public health professionals influence family planning initiatives, motor vehicle safety laws and clean air and water policies. It involves providing educational programs, administering services, developing policies and conducting research for the betterment of humankind.
