Effective Breathing Techniques for Open Water Swimming

Effective breathing in open water swimming means mastering bilateral breathing, controlled exhalation, and sighting rhythms that keep you calm and efficient. Unlike pool swimming, open water demands adaptability — waves, currents, and cold water all challenge your breath control. Start with a steady exhale underwater, inhale quickly to the side, and build a rhythm that matches your stroke rate. With practice, these techniques become instinctive and dramatically reduce fatigue.

Effective Breathing Techniques for Open Water Swimming

Core Breathing Fundamentals for Open Water

Bilateral Breathing

Bilateral breathing — alternating which side you breathe on — balances your stroke and keeps you swimming in a straight line, crucial in open water without lane lines. Aim to breathe every three strokes as a baseline. This pattern forces a complete exhale underwater, maximising oxygen exchange and reducing the breathlessness that catches many swimmers off guard in open water conditions.

Controlled Underwater Exhalation

Many swimmers hold their breath underwater without realising it, which causes carbon dioxide to build up quickly and triggers a panic response. Train yourself to exhale steadily through your nose and mouth the moment your face enters the water. By the time you rotate to breathe, your lungs are already partially emptied and ready for a full, efficient inhale.

Adapting Your Breathing to Open Water Conditions

Breathing in Choppy Water

Choppy conditions demand a higher breathing frequency and a lower head position during the inhale. Rather than lifting your head high, rotate your body more aggressively and use the bow wave created alongside your head to create a natural air pocket. Practise this in the pool by deliberately swimming closer to a lane rope to simulate the small wave effect before race day.

Sighting and Breathing Together

Sighting — briefly lifting your eyes forward to spot a buoy — disrupts your breathing rhythm if done poorly. The most efficient technique is to sight on the inhale: lift your eyes just above the waterline before rotating fully to breathe. This combines two movements into one fluid action, reducing drag and keeping your breathing pattern consistent even during navigation checks.

Breathing Drills to Build Open Water Confidence

Essential Drills to Practise

Targeted drills build the muscle memory you need before stepping into open water. Incorporate these regularly into your pool sessions:

  • Hypoxic sets: Breathe every 5 or 7 strokes to build CO2 tolerance.
  • Catch-up drill: Slows the stroke, forcing deliberate and timed breathing.
  • Sighting drill: Every 6 strokes, lift eyes forward then rotate to breathe.
  • Broken rhythm sets: Alternate breathing sides each length to improve bilateral comfort.
  • Cold water entry practice: Simulate the cold-water gasp reflex by briefly submerging your face in cold water before outdoor swims.

Managing the Cold Water Gasp Reflex

Cold water triggers an involuntary gasp reflex that can cause water inhalation if you enter unprepared. Before your swim, splash cold water on your face and neck to acclimatise your body gradually. Controlled breathing — slow inhales and long exhales — activates your parasympathetic nervous system and helps override the panic response within the first 30 to 60 seconds of immersion.

Post-Swim Recovery and Skin Care After Open Water Sessions

Why Open Water Swimming Is Tough on Your Skin and Hair

Open water exposes your skin and hair to UV rays, salt, algae, and environmental pollutants in ways that pool swimming does not. After every open water session your skin needs genuine care, not just a rinse. Salt and environmental residue strip your skin barrier, leaving it dry and reactive. A proper post-swim routine with swim-specific products makes a real difference in how your skin and hair recover between sessions.

The TRIHARD Post-Swim Routine

Start with Travel Kit - After-Swim Body Wash Extra Boost to cleanse environmental residue and help refresh your skin after open water exposure. Follow with Travel Kit - Pre & Post Swim Body Lotion to replenish moisture and hydrate skin that has been stressed by salt and sun. For your hair, the Travel Kit - Swimmers Shampoo Extra Boost and Travel Kit - Pre & Post Swim Conditioner work together to cleanse and restore softness. If you regularly compete outdoors, The Ultimate Swim Care Kit covers every step in one complete package. Open water swimmers who want a convenient travel solution should consider the Variety Travel Kit - 32 Sachets — perfect for race weekends and training camps away from home. After long sessions in goggles, apply Goggle Marks Soothing Gel to help soothe the sensitive skin around your eyes. If you experience persistent skin irritation after open water swims, ask a pharmacist or doctor about suitable over-the-counter options. If symptoms persist, spread, or worsen, see a doctor or dermatologist.

Frequently Asked Questions

How often should I breathe during open water swimming?

Most swimmers breathe every 2 to 3 strokes in open water, adjusting to every 2 strokes in rough conditions. Prioritise a consistent rhythm over a fixed number to stay relaxed and efficient.

Can anxiety affect my breathing in open water?

Yes. Pre-race anxiety raises your breathing rate and can trigger hyperventilation. Practise slow, deliberate breathing drills on land and in cold water to train a calm response before competition.

Does TRIHARD make products suitable for open water swimmers?

Absolutely. TRIHARD's swim-care range is designed for all swimmers. The Ultimate Swim Care Kit and Variety Travel Kit are ideal for outdoor and open water athletes.
