Effects Of Climate Change On Human Health

Let’s have a look at several insights focusing on the impact of climate change on human health: 

1. Direct and Indirect Health Impacts of Climate Change

Climate change has an impact on health in various ways. These include direct impacts, like extreme weather situations or shifts in temperature, and indirect effects, which happen when alterations occur within natural systems, such as crop failure due to changes in the ecosystem, expansion of disease vectors and migration of people. Further, a manifestation of the impact can be: 

• Based on the changing severity or frequency of health problems people are already experiencing.
  
  

• Cause new or unexpected health problems in people, like Suppurative lung disease or conditions that have not previously been experienced. 

These mechanisms make people more susceptible to diseases and injuries, as well as contribute to issues with their jobs and mental health. They also increase the risks related to lack of resources and migration.

2. Climate Change and Emerging Diseases

Climate change is a major factor in the emergence of diseases in new parts of the world, such as Nipah Virus Infection and Swine Influenza. Changes associated with global warming may affect the survival, reproduction, abundance, and distribution of pathogens, vectors, and hosts. Extreme weather events can result in ideal conditions for the spread of infectious diseases such as cholera. As global temperatures rise, so do diseases that were once confined to warmer regions.

3. Vector-Borne Diseases and Climate Change

Pathogens that transmit through vectors are becoming a growing threat to human health. And now they are on the rise. Many emerging infectious diseases originate in these tropical regions, where high temperatures suit the life cycles of both pathogens and vectors. 

For instance, in the case of climate change, mosquitoes and their related diseases like malaria, dengue fever or Zika could possibly propagate and endure at higher latitudes and altitudes. Additionally, increased rainfall might lead to breeding places for vectors (mosquitoes) multiplying further, thus increasing the parts of the world coming under threat from these deadly illnesses.

4. Fundamental Health Factors Affected by Climate Change

Climate change affects some of the fundamental factors that affect human health, including:

• The safety of shelter

• Air quality

• Quality, safety, and supply of drinking water

• Food availability

• Levels of nutrition in foods

5. Predictions and Statistics

While climate change keeps happening, scientists predict more health problems related to it. The World Health Organization (WHO) says that experts think some effects of climate change will cause about 250,000 more deaths every year from 2030 to 2050 because of conditions like:

• Heat wave stroke 

• Malnutrition

• Diarrhoea

• Malaria

6. Reports and Findings

As per the IPCC Fifth Assessment Report, climate change is an alarming danger to human health. It will amplify existing hazards like injuries and illnesses from more intense heat or variable temperature changes. Around the world, 400,000 early deaths are connected with climate change yearly. The report also states that between 2030 and 2050, approximately every year, about 250,000 extra deaths might happen because of impacts caused by climate change.

7. Climate Change and Migration

Climate change may also play a role in migration, as it can push rural populations towards urban areas. However, residing in cities can increase the danger of sickness due to congestion and hotter weather.

Expert’s Advice 

Climate change poses many threats to everyone's health and well-being. It has an impact on the things we eat, breathe, drink, and shelter ourselves from. Climate change can also affect people's health and well-being by changing the frequency or intensity of extreme weather events and the spread of some diseases.

The Final Say 

The impact of climate change on human health is profound, and it poses significant risks to human health in many ways. Natural disasters and extreme weather events can cause injuries, mental health problems, and increased risk of infection and death. Damage to infrastructure can also cause setbacks in long-term health and well-being. Addressing climate change is critical to limiting these effects and health risks.

FAQs

1. Who is at more risk of developing health problems due to climate change?

Children and older people, as well as people in less economically developed areas, are at greatest risk of health problems related to climate change.

2. How can climate change affect human health? 

Climate change puts people at greater risk of diseases, as it causes higher temperatures, more rain and runoff, and hurricane effects. Health problems might involve gastrointestinal issues like diarrhoea, how it affects the body's nervous and breathing systems, and damage to the liver or kidneys.

3. What are the health effects of climate change?

Some health effects of climate change include:

• Increased heat-related illnesses

• Spread of vector-borne diseases

• Worsening air quality

• Food and water insecurity

• Mental health impacts
