Climate change is one of the most pressing issues facing humanity today. It is caused by the release of greenhouse gases into the atmosphere, which trap heat and warm the planet. Climate change is already having a significant impact on human health, and is expected to become an even greater threat in the future.
One of the ways that climate change is impacting human health is by creating new diseases and making existing diseases more widespread. This is due to a number of factors, including:
- Changes in temperature and precipitation patterns: Warmer temperatures and more extreme weather events can create conditions that are more favorable for the spread of diseases. For example, mosquitoes, which can transmit diseases such as malaria, dengue fever, and Zika virus, are able to survive in warmer climates and can spread diseases to new areas.
- Melting permafrost: Permafrost is frozen ground that contains a vast amount of organic matter. As the planet warms, permafrost is melting and releasing greenhouse gases into the atmosphere. This melting is also releasing ancient viruses and bacteria that have been trapped in the permafrost for thousands of years.
- Increased human-animal contact: Climate change is displacing people and animals from their traditional habitats. This increased contact between humans and animals can lead to the transmission of new diseases from animals to humans. For example, bats, which are known to carry a number of viruses that can cause disease in humans, are moving into new areas as the climate changes.
In addition to creating new diseases and making existing diseases more widespread, climate change is also exacerbating the health impacts of existing diseases. For example, air pollution, which is worsened by climate change, can trigger asthma attacks and other respiratory problems. Heat waves can also lead to heat-related illnesses and deaths, especially among the elderly and people with chronic health conditions.
Here are some of the specific diseases that climate change is creating or making more widespread:
- Mosquito-borne diseases: Climate change is expanding the range of mosquitoes and increasing the transmission of mosquito-borne diseases such as malaria, dengue fever, Zika virus, and chikungunya virus.
- Tick-borne diseases: Climate change is also expanding the range of ticks and increasing the transmission of tick-borne diseases such as Lyme disease, Rocky Mountain spotted fever, and ehrlichiosis.
- Foodborne diseases: Climate change is increasing the risk of foodborne diseases by creating conditions that are more favorable for the growth of bacteria. For example, warmer temperatures can allow bacteria to grow on food more quickly.
- Waterborne diseases: Climate change is also increasing the risk of waterborne diseases by contaminating drinking water supplies with bacteria, viruses, and parasites. For example, flooding can cause sewage to overflow and contaminate drinking water supplies.
- Respiratory diseases: Climate change is worsening air quality and increasing the risk of respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), and lung cancer.
- Heat-related illnesses: Climate change is increasing the frequency and severity of heat waves, which can lead to heat-related illnesses such as heat exhaustion and heat stroke.
What precautions can be taken to protect against diseases caused by climate change?
There are a number of precautions that can be taken to protect against diseases caused by climate change. These precautions include:
- Reducing mosquito bites: This can be done by using insect repellent, wearing long sleeves and pants when outdoors, and avoiding areas where mosquitoes are present.
- Preventing tick bites: This can be done by using insect repellent, wearing long sleeves and pants when outdoors, and checking your body for ticks after being outdoors.
- Handling food safely: This can be done by washing your hands thoroughly before and after handling food, cooking food to a safe temperature, and keeping food refrigerated.
- Drinking clean water: This can be done by boiling or filtering water before drinking it, and avoiding drinking water from sources that are potentially contaminated.
- Reducing air pollution: This can be done by driving less, using public transportation, and using renewable energy sources.
- Staying hydrated and cool during hot weather: This can be done by drinking plenty of fluids, avoiding strenuous activity during the hottest part of the day, and staying in the shade or in air conditioning.
In addition to these individual precautions, public health officials can also take a number of steps to protect against diseases caused by climate change. These steps include:
- Surveillance: Monitoring for the spread of diseases and identifying new diseases that may be emerging due to climate change.
- Prevention: Implementing programs to prevent the spread of diseases, such as mosquito control programs and food safety programs.
- Preparedness: Developing plans to respond to outbreaks of diseases.
- Resilience: Building
Here are 10 daily hacks to safeguard yourself from climate change diseases:
- Use insect repellent. This is one of the best ways to protect yourself from mosquito-borne diseases such as malaria, dengue fever, Zika virus, and chikungunya virus. Apply insect repellent with at least 20% DEET to all exposed skin when outdoors, especially during dawn and dusk when mosquitoes are most active.
- Wear long sleeves and pants. This is another good way to protect yourself from mosquito bites and tick bites. If you must be outdoors during mosquito season, wear long sleeves, pants, and a hat.
- Check for ticks. After being outdoors, check your body for ticks, especially in areas where they are common. If you find a tick, remove it immediately with tweezers.
- Wash your hands often. This is a simple but effective way to prevent the spread of foodborne and waterborne diseases. Wash your hands thoroughly with soap and water before and after handling food, using the bathroom, and changing diapers.
- Cook food to a safe temperature. This will help to kill harmful bacteria that can cause foodborne diseases. Use a food thermometer to make sure that meat is cooked to the proper internal temperature.
- Drink clean water. Avoid drinking water from sources that are potentially contaminated. If you are unsure about the safety of the water, boil it for at least one minute before drinking it.
- Reduce air pollution. Use Masks regularly to prevent Air pollution which may exacerbate respiratory diseases such as asthma, COPD, and lung cancer. To reduce your exposure to air pollution, avoid driving if possible, use public transportation, and walk or bike whenever possible.
- Stay hydrated and cool during hot weather. Heat waves can lead to heat-related illnesses such as heat exhaustion and heat stroke. To stay safe during hot weather, drink plenty of fluids, avoid strenuous activity during the hottest part of the day, and stay in the shade or in air conditioning.
- Be aware of your surroundings. Climate change is increasing the frequency and severity of extreme weather events such as floods, storms, and wildfires. If you live in an area that is prone to extreme weather events, be aware of the risks and have a plan for what to do in case of an emergency.
- Stay informed. The more you know about climate change and its associated health risks, the better equipped you will be to protect yourself and your loved ones. Stay informed about the latest research and recommendations from public health officials.
By following these daily hacks, you can help to protect yourself from climate change diseases.
