Simple Guide to Minecraft/Heath & Hunger

In Minecraft, the health gauge and monitor show the player's remaining health. It consists of a row of 10 heart icons, where each heart is divided into two halves, representing one health point each. In most game modes, including Survival, Hardcore (Java Edition only), and Adventure, as well as for mobs (in-game creatures), the health meter is displayed using these hearts. Each heart represents two hit points, and when players or mobs take damage, they lose hit points. The damage can be a fraction of a heart, but anything less than 1 heart is not shown on the health bar. The maximum health points for a player are usually 20.

In Hardcore, hearts have it different texture.The Poison effect makes your hearts turn yellow while slowly damaging you, same with the Wither effect. Freezing in powder snow turns your heart icy blue.

Hunger is a player-specific feature (that doesn't apply to mobs) that affects certain abilities like health regeneration and sprinting. The player's hunger level is displayed as a hunger bar, located opposite the health bar, and consists of ten drumsticks. Each half of a drumstick represents one hunger point or half-unit of hunger, making a full bar equivalent to twenty hunger points. Hunger is replenished by eating food and decreases when the player performs actions like sprinting, digging, or attacking. The player's hunger level determines health regeneration and sprinting ability. When hunger is at 18 drumsticks, health regeneration occurs, but if it falls to 6 drumsticks, the player can no longer sprint. If the hunger bar reaches zero, the player's health starts to deplete. It's important to note that hunger does not deplete in Peaceful difficulty and regenerates if not at the maximum value.

The Hunger effect is received by eating rotten flesh, and it turns your hunger bar green/yellow. When you have the Hunger effect, your hunger depletes faster.
