Swimming in Cold Water — What’s the Best Technique?

May 8, 2026

Quick Answer

To swim in cold water effectively, use a vertical stroke with minimal body rotation, keeping your head above water for air. This reduces heat loss from the core and promotes a steady breathing rhythm. A horizontal body position helps conserve energy.

Breathing and Relaxation Techniques

When swimming in cold water, breathing is crucial for maintaining a steady heart rate and conserving energy. The horizontal body position described above helps to reduce energy expenditure. To breathe efficiently, practice taking slow, deep breaths through your mouth and nose, with a pause between each breath to avoid hyperventilation. Aim for 2-4 breaths per arm stroke.

Efficient Strokes in Cold Water

Choose a stroke that suits your skill level and promotes efficient heat retention. The horizontal stroke, also known as the “freestyle,” is ideal for swimming in cold water due to its low energy expenditure and minimal body rotation. For a more efficient freestyle, focus on a wide, streamlined body position and use the hips to generate power. Aim for 20-25 arm strokes per minute to maintain a steady pace.

Additional Tips for Endurance Building

When training in cold water, prioritize building your endurance over speed or distance. Start with shorter intervals (25-50 meters) and gradually increase the distance as you acclimate to the water temperature. To increase your swimming endurance, incorporate strength and flexibility exercises, such as push-ups, squats, and arm circles, into your training routine.
