Health includes physical, social and mental well being. There are umpteen factors which affect the health directly or indirectly. Some of the main factors include Climatic Changes ,environment , Society which is discussed elaborately later .Human beings are exposed to climate change through changing weather patterns  and indirectly though changes in water, air, food quality and quantity, ecosystems, agriculture, livelihoods and infrastructure . These exposures can cause death, disability and suffering and sick health that means uncomfortable conditioned health increases vulnerability and reduces the capacity of individuals and groups to adapt to climate change. Populations with high rates of disease and frailness cope less successfully with stresses of all kinds, including those related to climate change. Environmental change poses unique challenges to human health. Unlike health threats caused by a particular toxin or disease pathogen, there are many ways that a change in environment can lead to potentially harmful health effects. There are direct health impacts from heat wave, ailments caused or exacerbated by air pollution and airborne allergens, and many climate-sensitive infectious diseases. Realistically assessing the potential health effects of climate change must include consideration the power to manage new and changing climate conditions. Whether or not the healths risks are increased due to climate change are realized will depend largely on responses and underlying vulnerability. The probability of aggravated health risks due to climate change points to a need to maintain a strong public health infrastructure to help limit future impacts.

Human biology binds physical and mental state of a person. Social being plays a pivotal role in assessing the anatomy of health. Social determinants of health” grew out of researchers’ search for the specific mechanisms by which members of different socio-economic groups come to experience varying degrees of health and illness. Everywhere, individuals of different socio-economic status show profoundly different levels of health and incidence of disease. Factors such as income, social status, education, literacy (health literacy to be specific), culture and even gender in some cases .This depends mainly on the economy of the country i.e., the amenities and health care they can provide to their citizens. Mainly the developing countries such as India, Sri Lanka   depends more on this factor. And countries such as Germany, USA, and Cuba take care of the people health by having compulsory health insurance.
