Fresh water has a LOT of oxygen dissolved in the water, and especially in cold seasons where the water is colder and has a higher concentration of oxygen.
You know how when you let a cup of water sit out in the open and air bubble start to appear on the side of the glass? That's the oxygen coming out of the water.
When a fish is placed in such fresh water, those air bubbles can form on the fish and on their gills and that oxygen can actually burn their gills. :O Hence why if you can, let the water age. Usually I leave my water to age for about 6 hours before i put my fish back into the water. By then all the air bubbles have formed on the side of the tank and won't form on the fish.
I forgot where I read it (I'll go fishing for the source) >.<;; I'm not sure if it's just oxygen or a combination of several gases, but apparently those air bubbles burn their gills... and that would make sense. :/ I mean personally I'd like to reduce the stress caused by water changes for my fish. And if those air bubbles hurt them, it'll probably stress them out.
[edit:] Found it!

Most people also prefer to age their water for atleast 24 hours. This helps to get the extra oxygen out from running it from the tap. The bubbles from unaged water can result in gill burn if they get on your betta.
@Romad: Oh! I totally forgot about that! Dx Jeez! Thanks xD!
@Dramaqueen: :D Thanks! That's a good one!
@Jupiter: I don't know Dx but probably...
Yeah, personally I don't like under gravel filters but I think I was probably using the one I had wrong >_>;; or something... but APPARENTLY they're very good D: But I think it's still good subject to write about.
