# Respiration Enchantment in Minecraft: What It Does and How to Use It

_Published October 16, 2026_

Respiration extends underwater breathing time and cuts the odds your air ticks down at all — the exact numbers per level.

Respiration extends how long you can stay underwater before you start drowning — and also cuts the odds of losing air each tick you're submerged.

## What Respiration actually does

Each level adds roughly 16 seconds to how long your air supply lasts before you start taking drowning damage: about 32 seconds total at level I, 48 at level II, 64 at level III (vs. 16 seconds with no Respiration at all). Separately, it also reduces the *chance* your air supply ticks down at all on a given tick — 50% at level I, ~67% at level II, 75% at level III — meaning both effects combine to make underwater time last considerably longer.

## How to use it

Respiration is for anyone spending real time underwater — ocean exploration, monument raids, underwater builds — without constantly surfacing for air. It has no interaction with Aqua Affinity (which speeds up mining underwater instead of extending breath) — many players run both on the same helmet.

## Well-known builds that use it

Respiration III is part of [The Ideal Helmet Enchantments](/guides/ideal-helmet), alongside Protection, Aqua Affinity, Thorns, Unbreaking, and Mending.

## Frequently asked questions

**How much extra time underwater does Respiration III give?**

Around 64 seconds total before drowning damage starts, versus 16 seconds with no Respiration — plus a separate 75% chance each tick that your air supply doesn't tick down at all.

**Does Respiration help with mining speed underwater?**

No — that's Aqua Affinity's job. Respiration only extends how long you can stay submerged before drowning; many players run both enchantments on the same helmet since they don't conflict.
