風邪の原因 Cause of cold






There may be mental or physical reasons for that, but in my case, it would be carelessness.

Recently, I caught my second cold in the short period of time of a month, which was caused by wearing too light clothing at breakfast in the hotel and falling asleep on the Shinkansen.

Both colds could have been prevented if I had worn a jacket over my clothes, so I can only say that I was careless.

I missed two meetings last week, partly because of preventing transmission to others.
