Role of science in health
Science provides the foundation for credible decision making, adequate knowledge about risk to human health and innovative solutions to prevent diseases and offer high quality of life. Many chronic and infectious diseases are related to environment factors. High concentration of ozone, particulate matter can worsen respiratory diseases like asthma or emphysema. NASA's goal is to help to determine how weather, climate and environmental conditions correlate with the occurrence of infectious diseases. Public healths problems are caused by the environmental contamination are a growing concern worldwide. Public health threats are affected by the relationship between people and physical, chemical and biological nature of our environment. Science play a significant role in providing scientific knowledge and information that will improve our understanding of the environment conditions to diseases.
Science is a powerful means of understanding the world in which we live and it is also capable of yielding socio-economic development and enhance the quality of our lives. Science over the last fifty years have led to revolutionary changes in health and nutrition. National institute of health is the primary federal agency for conducting and supporting medical research. Scientists investigate ways to prevent disease, cause, and treatments of the common and rare diseases. National medical research agency provides leadership and financial support to researchers and scientists in every state through out the world. Science has played a significant role in improving health of the whole nation.
Medical science supports and conducts medical research how the human body works and to gain insight into diseases and disorders from rare to most familiar diseases. Science supports a wide spectrum of research from learning how brain becomes addicted to additives to combating heart disease. Science plays an important role for developing new ways of diagnosis and treat disease like cancer or other serious diseases. Science technology has improved new and imaging techniques that let scientists painlessly look inside body to detect diseases in its earliest stages.
There are two approaches of science; to study and research human body and high related issues to understand the human functioning and application of that knowledge to improve health and cure diseases. The increase longevity of human over the past few years is due to large part to medical research. Major advancement in medicine has been vaccines for measles, polio; insulin treatment for diabetes, medication for high blood pressure, new surgical techniques such as microsurgery and successful treatments for cancer. Health science field is as old as human race, with modern technology and backing of pure sciences has greatly improved.
To assess the contributions of science to health improvements, the goal of care must be addressed. A much effort of science is devoted to preventive measures and large measurable effect on the life expectancy of the population as a whole. A most important role of science is devoted to improve the quality of life and to minimizing the poor quality of life associated with chronic disease like to the relief of pain and disability. Science and technology are now seen not only have a strong connection to our health and daily life but also to the society's economic growth and its capability to generate societal well being.
Academically and technically considered, diagnostic, surgical and other skills of science is today far advanced. The knowledge of human body and its reactions to both external and internal stimuli is outstanding. All efforts of science are today concentrated on longevity of life. Man attitude will undergo a radical change when it is recognized that physical body is merely a channel of soul or its instrument of expression in the world of matter. Future scientific technology therefore will focus on prevention of disease and keep the instrument sound and efficient.
Scientific researches aggressively pursue ways to make effective vaccines for deadly diseases like AIDS, tuberculosis and malaria. Science play a significant role in understanding the immune system and may discovers new ways to treat the diseases like diabetes, asthma or allergies. For training scientific researchers will go to become leading medical researchers and educators at universities, hospitals, nursing and pharmacy schools, public health schools and medical research laboratories all over the country. Scientists are rapidly gaining an understanding of the biochemical process of aging and degenerating diseases associated with aging like cancer or brain deterioration.
These diseases appeared to be caused by accumulative damage to DNA in the cells. Science is completely different from trial and error and experiments are performed and preferably controlled in science. In science experiments are double blind it means neither the patient nor the experimenter knows who is getting the treatment and who is not. There is a great dichotomy in the state of medical science today. Modern medicine is greatly able to take care of many health problems.
Drugs not only provide quicker relief from pain, but there is so much profit generated and pharmaceutical companies do their best to discredit any nutritional approach to correcting disease. Profit generated by the drugs, radiation and surgery from the treatment of disease are so large that medical system do not change even when science is shows that these treatments are not effective. Department of agriculture have play a significant role in health.
