Why do we get Ill when there is a change in Weather

Can sudden change in weather cause certain diseases? Climate change is one of the environmental risk factors that most doctors consider when evaluating certain conditions in patients. “Changes in weather are basically a challenge to our immunity.” Our body is accustomed to a certain climate. We we get ill when there is a change in weather could be as a result of our body working hard to adapt. Unfortunately, sometimes it is difficult for our bodies to adjust, which may cause illness.

 

Concepts of weather and climate

Weather

Weather refers to short-term fluctuations (hours to days) in the atmosphere, not long-term or climate change. Weather is usually identified and studied in terms of brightness, cloud cover, humidity, precipitation, temperature, visibility and demeanor. Atmospheric changes occur as weather systems develop from atmospheric instability. However, the characteristics of weather systems are mainly determined by chaotic dynamics, so there is a lack of predictability for more than a few days.

 

Climate

Climate is usually defined as the average weather over a period of time (year) and a specific geographic area. Climate description and quantitative measures include statistical information on various climate variables. Due to the long time scales involved, these may include information about climate variability and extreme events. Climate involves changes in the interaction between the different components of the climate system, the atmosphere, the ocean, sea ice, and the land and its characteristics. It is said that the atmosphere is coupled with the biosphere and the ocean. Forests are part of the biosphere on land and are described as carbon sinks because they remove carbon dioxide from the atmosphere for photosynthesis. The ocean also serves as a sink, but heat is stored in its deep layers.

 

The following are the six health conditions that may be caused by sudden changes in weather

Environmental health issues have traditionally focused on the toxicological or infectious risks of local factors to human health. As we enter the next millennium, it is becoming more and more obvious that interference with natural ecosystems poses new risks to health. In the past 20 years, population growth and the spread of industrialization have been unprecedented in human history, leading to the accumulation of greenhouse gases in the atmosphere and beginning to affect the world’s climate.

  1. Upper respiratory tract infections and diseases
  2. Chronic sinus and throat problems
  3. Seasonal asthma and bronchitis are caused by cold air
  4. Seasonal allergies to pollen
  5. Cold and flu outbreaks
  6. Muscle and joint injuries

 

Impact of climate variability

The distribution and seasonality of important infectious diseases are likely to be affected by climate change. In sub-Saharan Africa, the epidemic of meningococcal meningitis has been erupting during the hot dry season and subsides shortly after the start of the rainy season. In contrast, many vector-borne diseases are limited to the rainy season. For example, most deaths from malaria usually occur at the end of the rainy season, although this is not the case in some parts of the world.

 

Classification of health effects

The potential effects of climate change on population health have been determined according to whether these effects are caused by direct effects of climate variables (such as temperature rise or weather variability), or through changes in indirect mechanisms (such as infectious factors) or mediated by ecological destruction. Physical hazards to human health include heat stress and extreme weather events; exposure to air pollutants and infectious diseases, especially water-borne and vector-borne microorganisms, and effects on food productivity and pollen and spore levels in the air.

Air pollution

Sulfate levels have been found to be significantly related to relative humidity in summer. The resulting concentration of acidic aerosols is a strong predictor of respiratory causes of hospital admissions in summer. At the peak of pollution, summer smog (which mainly includes ozone and acidic aerosols) is related to half of all respiratory admissions. Therefore, these atmospheric chemical reactions are essential for understanding the potential health risks under changing climatic conditions (including temperature and humidity).

 

Vector-borne disease-malaria

As we all know, malaria is affected by weather conditions. The humid and humid environment provides conditions for the breeding grounds of malarial mosquitoes and prolongs their life span. Temperature determines the speed at which mosquitoes develop into adults, determines the frequency with which they suck blood (and therefore acquire parasites), affects the survival of adults, and determines the incubation time of parasites in mosquitoes. *Waterborne diseases Waterborne diseases are particularly sensitive to changes in the hydrological cycle. In developing countries, water shortages cause diarrhea through poor sanitation. The weak or those with reduced adaptability are at greatest risk.

 

Aeroallergens

The outdoor air concentration of many air borne allergens (pollen, spores, mold, etc.) depends on the season of the year. Patterns of seasonal allergic diseases, such as asthma and allergic rhinitis (hayfever), may be affected by the effects of climate change on aviation allergens. Outpatient visits for hay fever coincide with the onset and duration of the pollen season; on the other hand, the worsening and seasonal distribution of asthma are more complicated. In temperate climates, asthma peaks during the pollen season and later in the year, while in tropical regions, asthma increases during the rainy season.

 

Conclusion

Any change in the components of the climate system, whether from internal or external forcing, may lead to climate change. Changes in the external components of the climate system may be caused by natural events such as volcanoes or human activities, such as increases in greenhouse gases, changes in atmospheric aerosol content, or extensive and sustained deforesting activities (thereby destroying important carbon sinks). Among all components, atmospheric circulation is mainly responsible for regional changes in climate variables, such as wind, temperature, and precipitation, whether in the normal range or extreme.
