Large amounts of a specific type of bacteria from outdoors may decrease the child's risk of developing asthma, reports a new study.

‘Exposure to specific outdoor microbes protects against asthma. Hence, exploring nature with children more often can increase microbial exposure and decrease asthma risk.’

However, the study was unable to identify individual bacterial taxa that provide protection against asthma.Read More..





It remains unclear why exposure to microbes protects against asthma. Earlier studies have found that high diversity of microbes is of particular importance in protecting against asthma.
THL's study, published in June, also showed that farm-like microbiota of the child's home protected children from asthma also in urban homes.
Finns spend 90% of the time indoors - contact with natural microbiota has decreased
On average, Finns spend 90% of the time indoors and more and more often in an urban environment. This means less contact with natural microbiota. The diversity of bacteria protects against asthma, but certain soil microbes protect even more effectively.

"If we want to develop products that protect against asthma, such as microbes that you can bring home or place on the skin, it would have been helpful to identify individual asthma-protective bacteria. However, our results help to restrict the bacteria that should be studied more." Increased contact with nature is beneficial.
