The weather has turned cold recently, and I often sneeze in the morning and evening, as if it was the same last year. Not in summer, but now I often sneeze at 20 degrees. What's the problem?

There are several reasons to consider.

1. May be allergic to something.

The air is dry and cold.

In the first case, there is no good way. You can pay attention to whether there are any plants blooming recently.

In the second case, you can wear a mask and try it, but you should pay attention to the cleanliness of the mask. It is best to scald it with boiling water every other day.

If not, you can go to the hospital for consultation.
