Small filter on the nose reduces symptoms by more than 50 percent
When the temperature rises, millions of people suffer from a pollen allergy like every year. The typical complaints such as runny nose, sneezing and reddened eyes can often be alleviated by proven home remedies for hay fever or medication. However, antihistamines can sometimes lead to unpleasant side effects such as severe fatigue, headaches or dizziness. A newly developed “nasal filter” could offer a new alternative, because it is said to significantly minimize the complaints.

Nose clip works like a filter and repels pollen
A nose clip as a remedy for hay fever? What sounds strange at first may be an effective aid for people with allergies to bollards in the future. As the Danish University of Aahaus reports, a recent study has shown that symptoms can be reduced by more than 50% in this way. The results were recently presented at the annual congress of the “European Academy of Allergy and Clinical Immunology” (EAACI) in Barcelona.

For the examination, the team of scientists led by Torben Sigsgaard and Peter Sinkjaer Kenney from the University of Aahaus examined a total of 65 allergic subjects who wore a special nose clip for two days each. Basically, it works like a filter, in that an almost transparent braid prevents pollen from entering the nose, but is not particularly difficult to breathe.

Subjects with a functional filter experience a significant decrease in complaints
Previously, the researchers had divided the participants into two groups, one with a functional and the other with an ineffective bracket. Over the next two days, Torben Sigsgaard and his team now observed the extent to which the classic hay fever symptoms such as a constantly runny nose, constant sneezing or reddened, burning eyes occurred in the test subjects and also documented their mood. The scientists came to a significant result because those who wore a functioning brace were significantly better off than those with a filterless placebo.

Particularly effective as a preventive measure
"The nasal filter reduced a number of the most common symptoms of hay fever such as sneezing, runny nose and watery eyes by more than half," said Professor Torben Sigsgaard in the Aarhaus University report. The clip had proven to be particularly effective as a preventive measure: “If the participants started using the filter before the onset of symptoms, the effects were even clearer. We regard this as an indication of a preventive effect of the nasal filter, ”Sigsgaard explains. Anyone who had used the small tool as a preventive measure was therefore free from symptoms such as sneezing and watery eyes all day long. After all, there was an 84 percent reduction in runny noses compared to the placebo group. The improvement in complaints from the use of the small brackets is thus greater than those achieved in similar studies regarding medical treatments, the message said.

“In addition, the participants with the functional nasal filters did not feel bad overall, although the pollen content in the air was significantly higher on the second day than on the first,” explains Peter Sinkjaer Kenney. This indicates "that the benefits of the pollen filter are getting better as the pollen in the air rises." In addition, it was shown that the brace was apparently able to reduce fatigue by more than 50% compared to the placebo group.

"This is interesting because sleepiness is one of the best known side effects of some commonly used antihistamines, and the allergy itself can also cause fatigue," said Sigsgaard. Accordingly, the “wake-up effect” could mean the greatest added value of the nasal filter for many sufferers - but it is not yet clear when it will be available for purchase. Previously, another study with more than 1000 allergy sufferers should bring new insights into the user-friendliness of the clip. According to the researchers, these would soon be published in the journal "Journal of Allergy and Clinical Immunology". (No)
