Reszing shrinks the image down to a smaller size. This is done through resampling the image. The resulting smaller image contains less information in it than the original and so it loses quality.

You can think of an image size as a room's size and the image itself as the stuff in a room. If you shrink the size of the room down, you also shrink the amount of stuff you can hold. So the smaller the image size, the less information in the image there is.

What you might want to try is to copy the original file and save it under a different name, then work on that copy. That way, you aren't risking the loss of image data in the original file when you resize the copy.
