The onset of dermatitis and the onset asthma are linked.
Inhaled allergic substance, asthma onset.
Skin attacked, dermatitis onset.
The difference, inhaled or hit.
Air pollution is said that increased allergies.
This time pick up about exhaust fumes, pollen, dust storm.
Air pollution is an alteration of the levels of quality and purity of the air due to natural or anthropogenic emissions of chemical and biological substances.
Today, tens of thousands of known or suspected air pollutants, sometimes acting in synergy with each other as well as with other parameters (temperature, wind, etc.), are taken into account.
Air pollution involved not only a substance but also other factors.
First : exhaust fumes
This study is very interesting.It is not comparison at different place, it is at same place.
The alternative transportation strategy implemented during the 2008 Summer Olympic Games in Beijing (China) provided an opportunity to study the impact of the control measures and weather conditions on air quality and asthma morbidity. The average numbers of outpatient visits for asthma were 12.5 per day at baseline and 7.3 per day during the Olympic events.This study used Olympic.
A lot of people come there during Olympic season.
Therefore, traffic regulation was done in Beijing.
Result, it is written that asthma patients decreased,and air pollution proved cause of asthma.
Second : pollen
Global warming affects the onset, duration, and intensity of the pollen season as well as the allergenicity of the pollen. Studies on plant responses to elevated atmospheric levels of CO2 indicate that plants exhibit enhanced photosynthesis and reproductive effects and produce more pollen.
Due to global warming, became pollen season longer and intensity of pollen in the air has increase.
Increased CO2 increase pollen too.
There is the data that growth range is widening.
Third : dust storm
Dust storm events were associated with asthma and respiratory admissions to hospitals in many studies. However, the effect varies among published studies. Although many studies have shown a significant increase in asthma exacerbations and hospital admissions, others have shown only mild association with no statistical significance between asthma outcomes and dust storm exposure.Put it simply, desert storms related to asthma. It can not prove why it happens.
Cause is known in Japan.
Similarly, pollens have been attributed to worsen asthma exacerbations during seasonal dust storms. Watanabe et al., showed worsening asthma symptoms during dust dispersion period, defined as the dust storm day plus the next 6 days in April in Japan, when Japanese cedar pollen levels were increased, which was more common in patients with allergic rhinitis or atopy than in those without.
Ceder pollen season and dust storm peak is same.
Increase asthma patients.
Dust storm and pollen is skin of enemy.
Please be careful.
Ragweed pollen is increase all over the world.
Stop climate change is very hard.
I think that better than myself correspond.
Thank you for reading.
