To solve the problem that the cause of pollinosis is extremely trivial; the
pollen dispersal rates in each prefecture and the associated incidence rates of pollinosis are inconsistent; even though people living in towns surrounded by cedar trees are exposed to yellow
pollen floating around like a mist every day, the number of pollinosis sufferers is not surprisingly high; the rate seems to be about the same as in urban areas, or even lower; prefectures with many mountainous areas and rugged
terrain have fast-flowing rivers that wash
pollen downstream; this is why mountainous prefectures have fewer pollinosis sufferers; prefectures located in flat areas, such as the Kanto Plain, have poor river flow, which causes pollen to stagnate and become
tap water, resulting in high rates of pollinosis; Yamanashi Prefecture's basin
water flow is poor, resulting in stagnant water and pollen-laden
tap water; and identifying the cause first leads to a solution.SOLUTION: As I mentioned earlier, I believe that pollinosis is caused by pollen contained in water, and I think that it is important to investigate this. If we understand that
tap water contains pollen, I think that we will naturally be able to find a solution, and pollinosis will disappear.SELECTED DRAWING: None
