How do I restore my Health?

You practice previous material to restore it (i.e. if you tap on Global Practice and complete it, you should earn Health bars again). Each lesson practiced will restore one bar. Or you can take a break and let it refill on its own. Five bars is considered “full” Health. For those who still want to binge on Duolingo without taking a break or taking the time to review lessons, Health can also be refilled with Gems.
