Fog not only obstructs vision while participating in traffic, but it also poses many dangers to humans as it contains many toxic pollutants. Let’s find out about the effects of fog on health and prevention methods through the following article!
1 Impact of fog on health
Fog is a natural phenomenon caused by water vapor rising and condensing into small water droplets suspended in the air. However, fog in big cities is often very harmful to health due to the high risk of containing toxic substances from air pollution.
Polluted fog affects the respiratory system
The first impact of fog on health that needs special attention is its impact on the respiratory system of any individual, from infants to the elderly, from females to males.
When fog is too dense, it greatly affects people with respiratory problems such as asthma, making the condition worse. The reason is that when you inhale foggy air, your lungs are exposed to cold, moist air that causes chills and irritations.
Individuals with weak immune systems or respiratory diseases also make the body more vulnerable to illness or more severe disease when exposed to polluted fog.
Impact of fog on health
Polluted fog can cause eye irritation
Exposure to polluted fog is prone to cause eye irritation, infections, eye pain, and uncomfortable redness.
Fog can worsen joint pain
People with joint problems often experience more pain on days with heavy fog because the combination of low temperature and humidity causes joint stiffness, making the condition more severe.
Moreover, low air pressure can also cause already damaged tissues to become more painful and heavier.
In addition, during winter, many people tend to be less active, leading to stiff and less flexible joints, which can cause surrounding tissues and muscles to become tense and painful.
Fog can worsen joint pain
Fog can affect heart health
People with heart disease often feel uncomfortable due to high humidity in the early morning due to fog, especially the elderly with poor circulation, with a higher risk of heart failure in the morning due to the effects of fog.
Moreover, when the temperature drops, blood vessels contract, forcing the heart to work at full capacity to pump blood throughout the body.
Fog can affect people’s mood
People with seasonal depressive symptoms often feel more uncomfortable and unsettled when there is a lot of polluted fog. The dark, gloomy outdoor atmosphere makes them feel more tired and despondent.
