The impact of climate change consists of rising sea levels, changes in precipitation, warming temperatures, and increases in the intensity or frequency of various extreme weather events. All these impacts have tremendous effects on human beings’ health by affecting the food, water, air, and the weather we all experience.
Moreover, the severity of these health effects will depend on the capability of safety systems and public health to prepare or address these climate-changing threats along with other factors like an individual’s age, behavior, economic status, and gender. Though, the health effects of climate change will vary upon how sensitive people are too health threats, where they live, how much they are exposed to climate changes, and how their immune system is able to adapt to the change effectively.
It is seen that people living in developing countries may be more vulnerable to health threats globally. However, climate changes still pose a significant threat to the lives of people in healthier nations. However, specific populations like pregnant women, children, people with low incomes, and older adults are more vulnerable to climate change threats. So, without further ado, let us discuss the significant impacts of climate change on health effects.
- Extreme Heat
Extreme heat air temperatures directly contribute to respiratory and cardiovascular deaths, most probably among older adults. Moreover, an increase in heat level can also raise the ozone and other contaminants in the air that intensify respiratory and cardiovascular diseases. Besides, a higher temperature can also increase pollen and other aeroallergens in the air, which can trigger asthma problems in human beings. If you look at the rise in the current temperature, it is expected that the situation will worsen in the foreseeable future.
- Variable Rainfall And Natural Disaster Patterns
Worldwide, the frequency of weather-related disasters has tripled over the course of 50 years, and every year, these disasters have led to more than 70000 deaths, mostly in developing countries. Increasingly extreme weather events and rising sea levels will destroy medical facilities, homes, and other vital services.
However, almost half of the world’s population is living within 50 km of the marine. And people might be forced to move to higher altitudes to reduce the chances of climate change-related disease, but it will heighten the risk related to the health effects like infectious diseases and mental diseases.
On the other side, variable rainfall can affect the purity of the water supply, increasing the chances of diarrheal disease, which has led to the death of over 600000 children under the age of 5 years. Simultaneously, flood increases the contamination level of the fresh water and heightens the risk of water-related diseases.
- Infection Pattern
The health effects of climate change include diseases transmitted through snails, insects, or other cold-blooded animals. Moreover, climate changes can increase the level of transmitted diseases through vector insects, and It might also alter the geographic range, which can significantly increase the transmitted disease.
These are the top significant impacts of climate change on the health of human beings.
