Climate Change Effect on Health

4 min read

It is well documented that climate change can have a negative impact on health. Heatwaves, air pollution, infectious diseases, and malnutrition are just a few of the factors that could have a negative effect on the health of a person. This article will discuss these issues, as well as the social determinants of health.


Heatwaves are a real threat to our health and wellbeing. These high temperatures can cause a wide range of physical, mental and social effects. They can also increase the risk of wildfires, power outages and damage crops and livestock.

Although climate change is already having an impact on our environment and quality of life, it’s the effect of heatwaves on human health that we’re really concerned about. Adaptation strategies ranging from local to national levels can help reduce the impacts.

A heatwave is an unusually hot day when air pressure at ground level is higher than average. The temperature may be a few degrees above normal or above or below the average temperature.

Heatwaves are expected to become more frequent and intense, increasing the chances of illness. One study found that in the United States, average daily maximum temperatures are projected to rise 10 degF by 2050.

Infectious diseases

A growing body of evidence suggests that climate change is a factor in the transmission and spreading of infectious diseases. Some studies suggest that warmer temperatures may help spread diseases such as West Nile fever, zika and dengue. But the specific mechanisms by which these diseases are transmitted remain undetermined.

The relationship between climate change and infectious diseases is complex and involves the impact of human behavior, the biological characteristics of pathogens and the health of their hosts. Climate changes also affect the routes of transmission, distribution and survival of disease pathogens.

A recent study by a team of researchers at the University of Hawaii at Manoa explored the impacts of climate hazards on disease transmission vectors. It was published in the peer-reviewed scientific journal Nature Climate Change.

Air pollution

Air pollution is a significant environmental hazard that has been shown to impact human health. It causes a wide range of adverse health effects, including heart and lung disease, systemic inflammation, and respiratory infections.

Climate change will likely affect air quality, as well as the concentration and distribution of various air pollutants. This is due to changes in meteorology, atmospheric transport, and pollutant deposition. The impacts of climate change on air pollution and health are currently being studied.

Using data from several studies, we examine the relationship between climate change and air pollution. We review recent evidence and identify knowledge gaps.

Air pollution has been linked to cardiovascular mortality, lung cancer, and respiratory infections. As temperatures rise, ozone-related mortalities are expected to increase. However, the effect of climate change on other air pollutants is less certain.


Climate change affects health and malnutrition in many ways. It causes droughts, changes the availability of food, and increases the risk of infectious diseases. In some regions, it is even causing near-famine conditions. The effects of climate change on child nutrition are particularly pronounced.

One in every three children around the world suffers from malnutrition. This includes stunting, a condition characterized by low birth weight and developmental delays. Many experts warn that the nutritional value of fruits and vegetables is eroding as a result of a changing climate.

Malnutrition is a major contributor to global obesity. Increasing temperatures also drive a higher prevalence of overweight and obesity. Some studies also indicate that poor diets contribute to epidemic infectious diseases.

The World Bank’s recent report suggests that a new global treaty on food systems should be created similar to the tobacco control treaty. Such a treaty would limit the influence of the food industry in policy making and mobilize national action towards sustainable food systems.

Social determinants of health

The social determinants of health are the nonclinical factors that determine access to medical care and quality of life. These include education, socioeconomic status, neighborhood, environment, and social policies.

Health care coverage is one of the most important social determinants of health. However, coverage alone is not enough to improve health outcomes. It is critical to address the full range of social factors that contribute to health inequities.

Many studies have found that the social and economic factors are the primary drivers of health outcomes. Although the health care system has traditionally been viewed as a key driver of health, more attention is now being paid to the non-health sectors, such as food and water.

Climate change affects health in many ways. It causes more extreme heat, floods, and injuries. Climate change also threatens the availability of food and water, leading to increased rates of vector-borne diseases, zoonoses, and illnesses. In addition, climate change worsens the trend of poverty. Children are particularly vulnerable, and will disproportionately experience negative health effects.
