In The Legend of Zelda: Tears of the Kingdom, Link’s health is represented by Hearts. Each Heart represents a portion of Link’s health, and he can have a maximum of 30 Hearts. Hearts can be increased by finding and completing Heart Containers, which are scattered throughout the game world.
Having more Hearts is important because it allows Link to take more damage before dying. This can be especially helpful in boss battles or other challenging areas of the game. Additionally, some items and abilities in the game require a certain number of Hearts to use.
