冬に人々が風邪やインフルエンザにかかる理由はいくつかあります。理由の1つは、冷気自体が鼻に発生する免疫応答を損傷することです。もう1つの要因は、天気が歓迎されなくなるにつれて、屋内でより多くの時間を過ごすことです。この呼吸器ウイルスの伝播の増加は、秋や冬の間、風邪やインフルエンザなどの上気道感染症の発生率が高くなります。
There are a few reasons why people get colds and flu more often in winter. One reason is that cold air itself damages the immune response occurring in the nose. Another factor is that we spend more time indoors as the weather becomes less hospitable. This increased transmission of respiratory viruses leads to a higher incidence of upper respiratory infections such as colds and flu during fall and winter.
