Public health problems caused by environmental contamination and emerging infectious diseases are a growing concern worldwide. These public health threats are affected by the relationship between people and the physical, chemical, and biological nature of our natural environments. Population growth and the associated pressures of development are increasing the difficulties associated with sustaining effective public health practices and policies. Health and Fitness is now one of the major concern areas across the world. Easy lifestyle is what we are moving towards. Very less of effort spent on most activities like, travel by motor vehicles, air-conditioned environment, ready-made food stuff, etc.Vector-borne and zoonotic diseases, water contamination, airborne contaminants, bioaccumulative contaminants in the food chain, and environmental threats to public health the world over require marshalling of all our scientific knowledge and know-how to develop new solutions. Understanding environmental and ecological health is a prerequisite to protecting public health. As the Nation's natural science agency, USGS can play a significant role in providing scientific knowledge and information that will improve our understanding of the environmental contributions to disease and human health.
Your food shall be your medicine. Ayurveda has postulated the role of food and especially nutritive foods for maintaining health as well as cure of diseases. Nutrients are necessary for the proper functioning of mental, physical, metabolic, chemical and hormonal activities. The body is like a machine that will repair and rebuild itself if proper nutrition is provided by way of food.
Today, we hardly do any of those. Even a simple 30 mins per day of workouts and one good nutritious meal a day can help improve our health. This easy life has restricted humans to do that bit of physical exercise which is required to keep the body fit and healthy.Earlier humans used to hunt for their living, due to which their body had to undergo a lot of physical exercise. Every part of the body was exercised and the intake was more of natural substances.
Weather and climate play a significant role in people's health. Changes in climate affect the average weather conditions that we are accustomed to. Warmer average temperatures will likely lead to hotter days and more frequent and longer heat waves. This could increase the number of heat-related illnesses and deaths. Increases in the frequency or severity of extreme weather events such as storms could increase the risk of dangerous flooding, high winds, and other direct threats to people and property. Warmer temperatures could increase the concentrations of unhealthy air and water pollutants. Changes in temperature, precipitation patterns, and extreme events could enhance the spread of some diseases.
