It's difficult for me to take a breath. How can I swim with my head always over water?
The easiest way to swim with your head out of the water is to swim Breaststroke.
The body position for breaststroke allows your legs to be deep in the water and your head, mouth and nose out of the water, and the stroke to still be effective. You will need a strong leg kick to keep you up and moving. A long stretch forward with your arms after each arm pull will also help.
