Increased allergy season
Climate change has an effect on the length of the allergy season, lengthening the allergy season by 25 days in some areas since 1995. This is mainly due to the fact that climate change is causing warmer and longer summers. This creates something called "super pollen" that is larger and more allergenic. Climate scientists predict that pollen counts will double by 2040, as a result of climate change.
 
Increased disease
Climate change has an effect on the amount of disease, lessening the amount of disease-carrying pests that are killed. This is due to the fact that climate change shortens winters. This decreases the kill rate of certain disease-carrying animals, unfortunately increasing diseases in the world, such as the West Nile virus, Lyme disease, and malaria are seeing breakouts. While all these diseases have some sort of medication you can take to stop the disease from killing you, climate change can cause all diseases to increase in amount, but I won't go into detail on the specific diseases. This bacteria can also contaminate drinking water. 
 
Temperature-related injury becomes more common
Climate change is obviously causing the planet to be hotter. Climate change also causes more frequent and intense heat waves, which makes your home area even hotter. This can lead to heatstroke. In addition, hot temperatures correlate with kidney, respiratory and cardiovascular disorders.
 
Increased smog
A warmer atmosphere increases the formation of ground-level ozone, or smog, in polluted regions. Smog creates problems with lungs and triggers asthma attacks. Smoke from wildfires, which climate change causes, further downgrades the quality of the air.

Under-nutrition
Climate change can lead to under-nutrition. This is due to the fact that climate change causes agricultural deterioration. This can lead to not enough plants being grown, and an overall food shortage. American and United Kingdom climate studies show that harvests of cereal grains including wheat, maize, and rice, decreased by an average of nine to ten percent during heat waves and droughts from 1964 through 2007. Other studies show that children are experiencing stunted growth and are wasting at an increasing rate. In addition, climate change is causing rising sea levels, and potentially flooding areas with good, fertile soil that would have been used for farming. This would also lead to an overall food shortage.
