Today the topic of climate change flooded the world. And it can not but rejoice,because the more we know about the problem, the more we learn about the methods and ways of its decision. Global warming affects not only the animals that lose their accustomed habitat, but also us. Scientists concerned about the impact of climate change on human health. First and foremost, this applies to people with allergies. According to recent studies, climate change will exacerbate the symptoms and frequency of allergic diseases.
Why the climate is changing on Earth?
The scientific community agree that the climate is changing rapidly. Blame the anthropogenic factor — the direct human impact on the environment. Population growth, deforestation, the use of a large amount of land for agricultural purposes and the gigantic scale of the production of very different products have a detrimental impact on the climate.
A large number of emissions into the atmosphere of our planet, contributes to the increase in the average temperature, which in turn can lead to catastrophic consequences in the near future. Today, however, experts are also concerned about the impact of climate change on human health. A gradual temperature rise and record-breaking heat wave that took place in July this year, can significantly degrade the quality of life of many people around the world. Scientists say that one of the first climate change will be felt by allergies.
As climate change may cause allergies?
Those who are familiar with the myths of Ancient Greece know that ambrosia called food of the gods that granted them power. In fact, ragweed is a weed that looks like a shrub.
This is all very nice if not for one thing — in today’s world there is such a disease as ambrosial hay fever. Pollinosis is called a seasonal Allergy that affects people during the flowering of some plants. Hay fever manifests as sore throat, nasal congestion, itching and redness of the eyes. Pollinosis is often accompanied by or complicated by asthma.
Despite the fact that there are a large number of plants, the pollen of which causes the development of allergies, today the attention of specialists focused to ragweed. More facts about climate change you will find on our channel in Yandex.Zen.
Ambrosial hay fever is the main threat to the health of Allergy sufferers
Ambrosial hay fever cause quarantine weed native to North America. In Russia, the plant was in the early twentieth century. In the South, ragweed blooms from late July to mid-October, causing allergies. Externally, the ambrosia is reminiscent of the green and yellow bushes. Power allergens this little weed is superior to its dimensions: one plant can produce up to 1 billion pollen grains, to the detriment of those who suffer from pollen allergies.
A global increase in temperature positively affects growth and flowering of ambrosia, which greatly complicate the lives of a large number of people. Extra warm 30 days, is expected to prolong the life and blooming period of ragweed and other plantsthat cause hay fever.
Allergists say that the number ambrosial plants over the last few years has increased as a consequence of the longer growing season. According to Stanley Fineman, MD, former President of the American College of Allergy, asthma and immunology, in the last few years there is a trend to increase the number of ambrosial plants. This is partly due to the increase in the duration of the season and the General warming of the climate.
In 2018 a study published in the journal PLOS ONE, researchers from the University of Washington and the University of Massachusetts showed that ragweed will expand its reach as a result of increasing temperature. Using machine learning, researchers have estimated that in about 35 years, and the ecological habitat will shift North that will cause hay fever in the regions where it was not observed before.
How are allergies and climate
Climate and allergies are associated not only with longer vegetation periods. Another part of the problem lies in the fact that ragweed thrives with higher levels of carbon dioxide. Therefore, the more carbon dioxide in the atmosphere, the better it grows and blooms ambrosia. A study published in 2000 showed that ragweed is increased in size when exposed to more carbon dioxide. Also, these weeds produce more pollen.
And you suffer from hay fever or pollen not afraid of you? Let's discuss methods of treatment and prevention of allergies in the comments and with members of our Telegram chat.
Seasonal allergies are more than sneezing, watery eyes and runny nose. The researchers found that as the deterioration of seasonal allergies, worldwide, a growing number of cases in the hospital because of allergies and asthma especially frequent similar cases in individuals under the age of 18 years. Recall that an Allergy is the trigger the occurrence of asthma.
