No fall damage in worldguard regions?

I have a private server and I'm planning on going public soon so I need to work out a couple kinks. One of the problems I have is in my spawn region you can get hurt from falling. In order to prevent this from happening I allowed the invincible flag. That solved the no falling damage problem but created a new problem. I now could not regenerate health in the spawn. (the heal-delay and feed-delay flags are both 1 and the feed-amount and heal-amount flags are both 1) The invincible flag seemed to lock the health and hunger in place preventing players from regenerating health while in the spawn. Here are the possible flags btw. So does anyone know how to prevent players from being affected by falling damage while at the same time allowing them to regenerate health.

Anybody?

Just use the invincible flag and put a heal sign in the entrance to spawn or in the center.
