because we put air from our mouth and the tea gets cold
Hot vapors are rising from the tea. When you blow these vapors away more can rise faster to replace them. Thus more hot vapor (and thus more heat) can leave the tea while you are blowing than when you are not and the tea cools faster.
This is the process which some use in the preparation of Tea.

Sugar dissolves faster in hot tea because the increase in temperature speeds up the kinetic energy of the sugar molecules, causing them to move more rapidly and collide with the water molecules more frequently. This leads to quicker dissolution compared to sugar in cold tea where the molecules move slower.
