How to breathe while swimming

Feeling short of breath while swimming can have several causes, including holding your breath, a rushed exhalation, lifting your head, kicking hard or swimming faster than you can sustain. Beginners can first practise a relaxed underwater exhalation and an unhurried rhythm.

Short answer

Exhale gently through your nose, mouth or both while your face is in the water. Turn to the air without straining, take a controlled breath in, then return the face to the water and resume the exhale. The suitable rhythm depends on the stroke, pace and learner.

Breathing while swimming: breathing out underwater and taking a quick breath in above the surface
Breathe out steadily underwater so you only need a quick breath in.

A common timing mistake

Some learners hold their breath while their face is underwater, then try to breathe out and in while their mouth is clear. This leaves little time to inhale and can make the breathing cycle feel rushed. A gentle underwater exhalation can make the next inhalation easier to time.

Breathing drills, in order

  1. Bubbles at the wall. In shallow, supervised water, put your face in and exhale gently for a comfortable duration. Lift, recover your breathing and repeat without straining.
  2. Bobbing. In chest-deep water where you can stand, lower while breathing out and rise to breathe in. Pause between repetitions; do not use rapid repeated breathing or prolonged breath-holding.
  3. Side breathing at the wall. Holding the wall, face in, exhale, then turn your head to the side (one ear stays in the water) and breathe in. Turn back and exhale.
  4. Kickboard breathing. Kick with a board, face in, turning to the side to breathe every few kicks.
  5. Add it to freestyle. Breathe as one arm pulls back, turning your head with your body.

Freestyle breathing for beginners

  • Turn, don't lift. Rotate your head to the side. Lifting it forward sinks your legs.
  • Keep one goggle in the water. That's about how far to turn.
  • Breathe with the arm. Turn as the arm on that side finishes pulling back, and return your face as the arm swings forward.
  • Pick a workable pattern. Breathing every 2 strokes on one side may simplify timing for some learners. Bilateral or other patterns can be introduced according to comfort, technique and goals.

Common breathing mistakes

ProblemFix
Running out of breath after a few strokesExhale fully underwater; don't hold your breath
Swallowing waterTurn a little more, and breathe from the corner of your mouth in the "pocket" beside your head
Legs sink when you breatheTurn your head instead of lifting it; keep looking sideways, not forwards
Water in the noseKeep a gentle stream of bubbles out through your nose
Stroke stops when you breatheKeep your leading arm stretched out in front while you turn

Breathing in breaststroke and backstroke

In breaststroke, you breathe in as your arms pull and your head rises naturally, then breathe out as you glide. In backstroke your face stays out, but a steady rhythm (in on one arm, out on the other) still helps.

Practise safely

Practise in water shallow enough to stand in, at a pool with a lifeguard or a capable adult watching you. Never practise breath-holding or floating alone in deep water. Children need close, age-appropriate supervision by a responsible adult.

Technique source

Swim England’s front-crawl breathing drills separate exhalation, kicking and full-stroke coordination. Beginners should practise only in conditions appropriate to their ability and avoid breath-holding challenges.

Common questions

Should I breathe out through my nose or mouth?

Either can work. Exhale gently through your nose, mouth or both, choosing the option that feels controlled and helps you keep water out.

Why do I feel tired so quickly when swimming?

Possible technique factors include holding your breath, lifting your head, kicking hard or swimming faster than you can sustain. Tiredness and breathlessness can also have non-technique causes. Stop if you feel unwell, dizzy, have chest pain or unusual breathlessness, and seek qualified medical advice.

Is it okay to breathe on one side only?

Yes, especially while learning. Practising the other side later may improve adaptability and stroke symmetry, but the appropriate breathing pattern depends on comfort, skill and goals.
