Hearts

Hearts are the health meter for the player in the Survival modes. Each heart is composed of halves, so this means the player can take 20 hit points before dying.

Hearts can be lost by falling from a height larger than 3 blocks (You lose .5 hearts per block past 3. EX: If you fall 4 blocks you receive .5 damage, if you fall 10 blocks you receive 3.5 damage), getting tackled by a monster mob, getting shot with an arrow, being on fire, suffocating underwater or inside a block and explosions. In Survival mode, eating a Red Mushroom will cause the player 1.5 hearts of damage due to the poison. When the meter has 2 or less hearts left, it will begin to shake to notify the player that they need to restore their health.

Hearts can be regained by eating food items, Pork, Grilled Pork, Apples, Mushroom Soup, Brown Mushrooms (only in Survival), Bread and Golden Apples. Setting the game mode to Peaceful will cause the heart meter to slowly replenish itself until full again. Armor can be crafted to prevent some damage taken.
