Hay fever in Japan
Hay Fever in Japan
Hay fever (pronunciation: /heɪ ˈfiː.vər/), also known as allergic rhinitis (pronunciation: /əˈlɜːr.dʒɪk raɪˈnaɪ.tɪs/), is a type of inflammation in the nose which occurs when the immune system overreacts to allergens in the air. The term "hay fever" originated in England, where some people had an allergy to hay and developed a fever.
In Japan, hay fever is commonly referred to as kafunsho (pronunciation: /ka.fɯɴ.ɕoː/), and is a widespread condition affecting many Japanese people, particularly during the spring season. The primary cause of hay fever in Japan is the pollen from sugi (Cryptomeria), commonly known as the Japanese cedar, and hinoki (Chamaecyparis obtusa), or the Japanese cypress.
Symptoms
The symptoms of hay fever include sneezing, runny or stuffy nose, itchy or watering eyes, and itchy throat, mouth, or skin. In Japan, the hay fever season typically starts in February and lasts until April, coinciding with the pollen release period of the sugi and hinoki trees.
Treatment
Treatment for hay fever in Japan includes over-the-counter medication, prescription medication, and allergy shots. Over-the-counter medication includes antihistamines, decongestants, and nasal spray. Prescription medication includes steroid nasal sprays, leukotriene modifiers, and immunotherapy injections.
Prevention
Prevention methods for hay fever in Japan include staying indoors on high pollen days, wearing sunglasses to protect the eyes, and wearing a mask to prevent inhalation of pollen. In recent years, the Japanese government has also been promoting the planting of less allergenic tree species to reduce the amount of pollen in the air.
