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. 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).
Public health also takes various actions to limit the health disparities between different areas of the country and, in some cases, the continent or world. One issue is the access of individuals and communities to health care in terms of financial, geographical or socio-cultural constraints to accessing and using services. Applications of the public health system include the areas of maternal and child health, health services administration, emergency response, and prevention and control of infectious and chronic diseases.
What is added sugar, anyway? It refers to sugar that is not found naturally in food. Honey in your tea is added sugar. The sugar in a banana is not. Some foods like yogurts and fruit bars may have both natural and added sugars, and it’s usually unclear from labels what the ratios of each are. But the FDA’s new food labels—which must be adopted by Jan. 1, 2020—will require companies to spell out the amount of “added sugar,” making it much easier to track your sugar load.
Believe it or not, “stress can increase your risk of heart disease 2.5-fold—similar to smoking and diabetes,” says Gianos. That’s because chronic stress puts the body into constant fight-or-flight mode, triggering inflammation, high blood pressure and other unhealthy changes. But mindfulness can be a powerful antidote to that modern state of overload. By focusing on our thoughts and sensations, we can learn to control our body’s response to stress.
