I was recently swimming underwater moving a dead body from the wall of Riften. I put on my helmet on that has the water breathing enchant. After a minute or so underwater I start hearing my character choking and losing health, I looked around to see if I was being attacked just in case. I was not, I surfaced and my health started to regenerate. Has anyone else encountered this problem with the water breathing enchant?

I forgot to add I had removed my helmet anfd re-equipped it, yet it still happened.

Is this a helm you enchanted?

I have that enchantment on my helmet and that as never happened to me.

I can't say I've ever experienced that glitch.
