The Health Meter in Horizon Zero Dawn
The Health Meter is a HUD item displaying Aloy's current/maximum health pool, represented both numerically and by the large red gauge. Aloy's health decreases whenever she sustains damage from enemy attacks or environmental hazards, such as fire and long falls. Once the gauge drops to 0%, Aloy dies and the player is sent back to the location of their last save.
If Aloy's health falls below 25% she can automatically regenerate it back up to the 25% mark if she avoids damage long enough for the recovery period to begin. Lost health can be restored by using the Medicine Pouch or consuming Health Potions and Full Health Potions via the quick-access tool wheel. The Banuk Werak outfits from Horizon Zero Dawn: The Frozen Wilds provide passive healing over time.
