Respiration in Minecraft is a helmet enchantment that lets you stay underwater longer by slowing how fast you lose air bubbles and slightly reducing drowning damage.

What Respiration Does (Quick Scoop)

  • Increases the time you can breathe underwater before you start taking damage.
  • Works only when it’s on a helmet (including turtle shells).
  • Slightly reduces how fast you take drowning damage when your air is gone, giving you a few extra moments to escape.
  • Activates automatically as long as you’re wearing the enchanted helmet—no extra buttons or items needed.

Exact Underwater Time

By default, you can stay underwater about 15 seconds before you start drowning. Respiration adds extra time based on level:

  • Respiration I: +15 seconds (about 30 seconds total underwater).
  • Respiration II: +30 seconds (about 45 seconds total).
  • Respiration III: +45 seconds (about 60 seconds total).

This makes underwater exploring, mining clay, looting ocean ruins, or fighting guardians much safer.

How You Use It

  1. Get a helmet (any type, including turtle shell).
  1. Enchant it with Respiration using:
    • Enchanting table,
    • Anvil with an enchanted book, or
    • Commands in creative worlds.
  1. Wear the helmet in your armor slot—Respiration is now active automatically.

Think of Respiration as your basic “scuba mask” enchantment: it doesn’t let you live underwater forever, but it stretches your breath long enough to actually build, mine, and explore without constantly panicking for air.

TL;DR: Respiration is a helmet enchantment that increases your underwater breath time by 15 seconds per level (up to 60 seconds total at level III) and slightly slows drowning damage, making underwater exploration much easier.
