Climate Change and Its Effects on Human Health

Climate change will also affect human health. The frequency of infectious diseases like diarrhoea, dysentery, cholera and typhoid fever will increase. According to the report of the World Health Organisation, there will be an increase in respiratory and heart related diseases due to climate change. Human health is impacted by climate change both directly and indirectly. Direct harm, disease, and even death can be brought on by extreme heat waves, increasing sea levels, changes in precipitation that lead to flooding and droughts, and powerful hurricanes. Via environmental changes, the consequences of climate change can also have an indirect impact on health. For instance, respiratory and cardiovascular problems may be negatively impacted by worsening air pollution levels. Temperature and precipitation variations can affect the survival, dispersal, and behaviour of insects and other animals, which can modify the transmission of infectious diseases. Changes in precipitation, storm surge, and sea temperature may cause an increase in illnesses associated with drinking water. In addition to affecting food safety, climate change exposes people to tainted foods that can cause foodborne illnesses.
