Hinoki pollen dispersal is at its peak. A large amount of hay fever is expected to be dispersed over a wide area this weekend, so people with hay fever need to take all possible precautions.
6 (Sat), there is a risk of large amounts of scattering over a wide area.
On 6 (Sat), pollen scattering will be suppressed in southern Kyushu due to rain. In northern Kyushu, Shikoku, and Honshu, the number of cases is expected to be “high” or “very high.”
Cherry blossoms will be in full bloom in Tokyo on Thursday, April 4th, and many other places from Kyushu to Kanto are also in full bloom. However, the scattering of cypress pollen has reached its peak in a wide area. I’m sure many of you are making plans for cherry blossom viewing this weekend, but if you suffer from hay fever, please take all possible precautions.
7 (Sun) is also likely to be scattered mainly in Honshu
On the 7th (Sunday), southern Kyushu and Shikoku will have “less” cases, and northern Kyushu and Kinki will have “slightly more”. In other regions, the forecast is “high” or “very high.”
Although the area will be a little smaller compared to 6 (Sat), there will be places where there will be a large amount of scattering.
Until when is the peak?
The peak period for cypress pollen is approximately 1 to 2 weeks. In many places, it will last until mid-April. In Sendai, the amount of cypress pollen scattered is small, and there is no expectation that there will be a clear peak.
Full-scale pollen dispersal, where pollen counts of 10 or more per square centimeter are observed, will not begin until early April in Kyushu, and mid-April in many areas from Chugoku and Shikoku to Tohoku. Parts of the Tokai region are expected to last until late April. However, even after full-scale dispersal has finished, there will still be days when pollen will be slightly scattered in various places until around early May. If you have symptoms of hay fever, please continue to take precautions.
Pollen countermeasures when going out
To alleviate the symptoms of hay fever, it is important to avoid pollen. Wear a mask and glasses, and dress wisely.
① Glasses
Experiments have shown that the amount of pollen entering the eyes is reduced by approximately 40% compared to when not wearing glasses, and by approximately 65% when using glasses for hay fever with protective covers.
② Mask
I think many people use it to prevent infectious diseases, but it can also reduce the amount of pollen you inhale by about one-third to one-sixth. It is important to choose a mask that fits your face. It is also known that applying gauze to the inside of the mask (inner mask) further reduces the amount of pollen entering the nose.
③ Ideas for clothing
In general, clothing made of wool attracts pollen more easily than cotton or synthetic fibers, making it easier to carry pollen indoors. Wool attracts pollen about 10 times more easily than cotton. When going out, avoid wearing woolen clothing on the outside and choose jackets made of smooth material.
