The warmer temperatures brought about by changing climate has led to an increase in intensity and frequency of natural calamities. This has made certain populations like -the children and the senior age group ( less able to regulate their body temperatures), people in developing countries ( with inadequate infrastructure to face climate change),and people in low-income group( with no access to air conditioning)- more vulnerable. Higher temperatures impact human health and safety. It has been observed that the heat-related deaths have gone up worldwide because of the  impact of weather pattern we are experiencing. Moreover, heat waves are typically followed by a period of time when air gets stagnant and polluted, adversely affecting the general health. Wildfires and heat also lead to rise in Carbon dioxide levels. All these factors combine to aggravate the allergen levels and ground-level ozone in the air. These present severe health risks like lung tissue damage, reduced lung function and inflamed airways. The poor air quality affects the home environment indoors too, and causes asthma and other such respiratory and cardiovascular health issues.

Additionally, the seeping of allergens into groundwater leads to stomach and intestinal illnesses. The toll these natural calamities take on mental health is apparent by the number of depression and post- traumatic stress disorder cases reported in such affected regions. Climate change, thus,  has a huge and wide-ranging impact on physical and mental health of community. Needless to say, it calls for investment in health infrastructure globally.
