Health, also known as Hit Points or HP, is a stat in Dark Souls.
Health is a numerical stat that represents the survivability of the player. It depletes when damage is received and can be restored by healing. When it reaches zero, death occurs.
The main way of increasing Health is through adding points to the Vitality stat when leveling up.
It can also be passively raised while wearing the Tiny Being's Ring, Ring of Favor and Protection or the Mask of the Mother. These items can be stacked to further increase Health.
Conversely, Health is lowered if the player is cursed, or if they equip the Dusk Crown Ring. These effects can be stacked, as well.
