Health regeneration

Health Regeneration is a Champion statistic that defines the rate at which health is naturally restored over time. Health Regeneration is measured in-game by a stat called HP5 (Health Per 5 seconds). HP5 describes how many hit points are restored in a 5-second window. The actual healing effect from regeneration is applied every half-second, not every 5 seconds. This stat is similar to Mana Regeneration, although health regenerates more slowly than mana. Health regenerated over time is considered to be a form of healing for the purposes of healing increases or decreases, and for the sake of the "Healing Done" stat at the end of game screen. There are many items, abilities, and buffs which can increase HP5 either permanently or temporarily.
