My nose clogs, throat irritates when i take sweets and fruits in winter ,why?
The establishment of allergic reactions are usually multifactorial. For example, A and B are brothers and allergic to hay pollen. Both went to a farm. A sneezed five times, and B sneezed many times and his nose got clogged. We say that A is less sensitive to hay pollen than B.


Two weeks later, A visited the same farm alone. Now he got clogged nose too. There are two possibilities: On his second visit, the density of hay pollen in the farm was higher, or his health condition was weaker. This means, the threshold to make the allergic reaction occur was lower.


Now going back to your question, you might be allergic to different kinds of fruits. If you eat them in summers, nothing happens. In winters, however, your threshold is lowered by cold temperature. Eating those same fruits, your nose clogs.
