The effects of climate change on human health are often invisible in the short term. However, they can have serious consequences for human health over the long term, hence the importance of observing their correlation. According to the WHO, climate change could cause 250,000 more deaths each year from 2030.

• Each year there is an increase in the surface temperature of the globe. According to experts, these temperatures could increase from + 1 ° C to + 5 ° C during the 21st century.
  Increasing temperature increases the frequency of phenomena such as heatwaves and droughts that have direct effects on human health. They are the cause of the increase in cases of "sunburn", dehydration and hyperthermia. Under these conditions, physiological adaptation becomes more and more complex.
• Ozone is one of the indicators of air quality. This gas attacks the ocular and respiratory mucous membranes. This causes dry coughs, asthma attacks and reduced lung function. Likewise, sulfur dioxide (SO2) is rapidly absorbed by moist surfaces of the mouth and nose. It causes awareness of respiratory infections. The same is true for fine particles. Numerous scientific studies have also shown that chronic exposure to these particles increases the risk of developing cardiovascular and respiratory diseases.
• Increasing water temperature and increasing its evaporation causing regular precipitation, promote the development of toxic bacteria, pathogens. These factors are responsible for the growth of cases of water-borne illnesses and cases of food-borne infections.
• Epidemiological studies demonstrate a correlation between the frequency of pollen allergies and air pollution. The latter makes pollens more allergenic and contributes to the increase in the pollination period.
