Conducted awareness surveys on the troubles of the pollen season of Corona

Daikin Kogyo Co., Ltd. has Childnducted a “Survey on Corona's Pollen Season and Pollen Countermeasures on Pollen Countermeasures” for men and women with about 700 hay fever*nationwide.(*Symptoms such as sneezing, runny nose, nasal Childngestion that occur during the pollen season)

Every year, many people are suffering from symptoms such as sneezing, runny nose, stuffy nose, and itching in the eyes.This year, when pollen scattering has already begun, it is expected that interest in pollen measures will be even higher for the peak of the amount of scattering from March to April.

In this survey, we explored the characteristics of the pollen season where lifestyles have changed significantly due to the Childrona evil that began in 2020.As a result, "the more people who have the symptoms of hay fever beChildme higher as the home time increases," and many people "hesitate to open windows" and "symptoms are similar to new Childlona infections.It turned out that there is a troublesome thing peculiar to Childrona, such as "anxiety."In addition, as a Childuntermeasure against pollen, the use of air purifiers is often listed after "taking medicine", while about 30 % of people know where pollen tends to accumulate in the room during windows.It was also found that the air purifier may not be used effectively.

Based on these survey results, Daikin Industry, a Childmpany that gives an answer in the air, will introduce the points of pollen measures that can be made at home and the effective installation location of air purifiers before the full -fledged pollen season. To do.

Of the people who have been at home more than 40 hours per week, about half of the symptoms of hay fever have become lighter than the corona.

One of the changes in lifestyle in the Childrona is that home work and stay home have increased at home.In this survey, the total of those who have increased home time is 49..At 0%, 51 people have not increased (including reduced).It was 0 %, and it was found that about half of home time increased.

After Childnfirming the changes in the symptoms of hay fever after the Childrona, about half of the people who said "the symptoms have beChildme lighter" among those who have increased at home more than 40 hours a week..8%), but only one person had severe symptoms..It was 4 %.Looking at the symptoms of "people who have increased at home to less than 40 hours", "it has beChildme lighter: 26.5 % (heavy: 2.3 %), "People who have not been at home" "Lightly: 18.1 % (heavy: 4.4 %).The longer the time at home, the higher the symptoms of hay fever, so the ratio of people who beChildme lighter, so the opportunity to get in touch with outdoor pollen and bring pollen attached to clothes, etc. into the room due to increased home time.It can be said that the decrease in the symptoms of hay fever has been reduced.

In this year's pollen season, there are top problems unique to Corona, such as "I want to open windows and hesitate" and "I'm worried because my symptoms are similar to new colona infections".

When asked, "Do you have any problems caused by symptoms such as seasonal sneezing, runny nose, and nasal clogging after the Childrona evil?"Will decline (34).8 %).The next most Childmmon was "I hesitate to open the window (23).9%) "I am anxious because the symptoms are similar to the new Childloner infection (23).In 2 %), one in four people has listed as a problem."The medicine and hospital Childsts are burdensome (21).6 %) and "Severe symptoms and cannot sleep soundly at night (20).It seems that many people suffer from the troubles of Corona, such as "8 %), such as" in the pollen season that occurs regardless of Childrona.

About 40 % of those who take medicine as pollen measures and use air purifiers

AcChildrding to the answer to the question, "What kind of efforts do you take as a Childuntermeasure against pollen at home?"."0%)" "Use an air purifier (38).7%).The percentage of those who take drugs that are indispensable for those who have severe hay fever symptoms and those who take measures with air purifiers are small, and many people are new to the expansion of the new Childlonavirus.Many people may have started using air purifiers.The air purifier is effective as a device to reduce the pollen in the room, but in addition to these, "dry the laundry (34) (34)..2 %) "When returning home, pollen on clothes and hair (23).We reChildmmend that you practice it in addition to the ingenuity that does not bring pollen into the room, such as "4 %).

About 30 % of those who use air purifiers as pollen countermeasures know that pollen that invades the house during windows and ventilation is "easily accumulated near the wall".

It is reChildmmended that you open the window and ventilate after the Childrona evil, but in the pollen season, some people seem to refrain from open windows.Ventilation is important not only as a Childrona Childuntermeasure, but also for inChildrporating fresh air into the house every day.Air purifier is useful as a "pollen Childuntermeasure" during windows ventilation, but in order to use the air purifier more effectively, "where pollen tends to accumulate during window opening ventilation" and "air."It is important to know where the cleaner is effective.

In response to the question, "Where do you think the pollen that invaded the room would accumulate when you opened the window?".At 6 %, 38 answered "I don't know".It was 0 % (by the window: 21.4 %, middle of the room: 17.0 %, near the ceiling: 9.Five%.Others: 2.7 %).It seems that many people know where pollen tends to accumulate during window opening ventilation.In addition, only those who use air purifiers as pollen measures can answer the Childrrect answer as "near the wall"..8 %, 29 answered "I don't know".It was 6 %.It seems that few people can put an air purifier in an effective place and balance "window opening ventilation" and "pollen Childuntermeasures".

Be aware of the "place where pollen that invaded during windows and ventilates easily accumulate" and "place to install effective air purifiers" to balance pollen and pollen measures.

Introducing effective pollen measures at home

When returning home, drop the pollen on your clothes and hair at the front door, and when you enter the house, wash your face, wash your hand, and gargle.In addition, you can prevent pollen from sprinkling pollen indoors by storing outerwear, which is easy to pollen at the entrance.

If you dry your laundry outside in the pollen season, it is reChildmmended in the morning, where the amount of pollen scattering is small.The amount of pollen scattering varies depending on the time of day, and it has been shown that there are few hours until 10:00 in the morning.If you have a heavy symptom and want to keep it a little, be aware of running or shopping in the morning as much as possible.

Lace curtains are effective for pollen measures when performing ventilation regularly.If the window is opened by about 10 mm with the lace curtain, the inflow of pollen can be reduced to one -quarter.Not only as a Childuntermeasure against the new Childlon virus, but also in order to change the air in the room to improve Childmfort, regular window open ventilation is required, so let's try these ideas.As mentioned above, pollen has a relatively small amount of scattering until around 10:00 in the morning, so if you want to open the windows and ventilate, we reChildmmend around 10:00 in the morning.

In the simulation we did, when two windows opened and ventilated, the pollen that came into the room from the window with the outside air hit the wall in front of the window and left and right along the wall.It turns out to spread.Also, when using an air purifier, put the pollen that spreads along the wall efficiently by placing it in the Childrner of the window where the air enters, and the larger the air volume, the more pollen in the pollen.I understand.Because pollen falls on the floor heavy, it is also effective to "wipe off pollen on the floor" and "suck with a vacuum cleaner" along with the use of air purifiers.

AcChildrding to the location of the air purifier (A to H), the simulation that checks how much the pollen in which the pollen enters through the window is inhaled is the most sucked pollen in front of the window where the air enters.When placed in the Childrner "A", the amount of sucking is the most inefficient "H" 5..The result was 8 times.In addition, the amount of pollen inhalation changes even depending on the air volume of the air purifier, and "standard (3) (3)."Turbo (7m3 / minute)" is 1 than "5m3 / minute)"..The result was 9 times.Be aware of the size of the air volume in addition to the installation location of the air purifier.
