Is it true that having a fan in our room running at night can have adverse effects on our health? Also, can having air conditioning in this hot weather help asthma?

Hello Mrs.,In fact, by reducing the humidity of the air, an air conditioner can make life easier for asthmatics in these hot weather periods. As for your question about the spinning fan, to my knowledge and according to my research, there is no evidence that it has any negative effects on our health.
