This may be a small local community or an entire country, rather than on an individual level. Protecting and improving health can be achieved through education, promotion of healthy lifestyles, and research for disease and injury prevention. Public health professionals may work on analysing the effect of genetics, lifestyle choices and environmental factors on health, in order to develop interventions to protect and improve health. There is a range of employers offering public health roles in local authorities, the NHS, health policy settings, academic research, voluntary/community organisations and international health settings. There is a helpful introductory video about public health on YouTube.
Working in public health can be a very rewarding career. By looking at the health of the whole population, you can understand and eventually influence various social, environmental, cultural, economic and political factors affecting health and well being. While clinical medicine is vital for helping and supporting people when they fall ill, public health work provides opportunities to contribute to reducing the causes of ill health and improving people’s general well being. These opportunities include: developing systems to protect people’s health from environmental or human emergencies; helping people to improve their own health; and ensuring that our health services are the best and the most appropriate. Current big public health issues include dementia, cancer and mental health.
