How to stay afloat in deep water
Learn how to stay afloat and survive in deep water, even if you are not a confident swimmer. In this beginner swimming lesson, Vladimir from ISWIM explains how breathing affects buoyancy and shows a simple survival position that helps you keep your face above the water, save energy, and call for help. You will see what happens when you hold a full breath, release half of the air from your lungs, and fully exhale. You will also learn how to turn onto your back, stay calm, and use gentle movements of your hands and legs to reach a nearby wall, float, boat, or another safe object. This lesson is helpful for anyone learning how to float, overcome a fear of deep water, improve water safety, or learn basic swimming survival skills. Always practise swimming and floating skills in a supervised pool with a qualified instructor or lifeguard present. Never practise alone.

Frequently Asked Questions
Is this lesson suitable for beginners?
Yes. The video breaks the skill into manageable steps. Begin with the easiest supported version and progress only when you can stay relaxed and in control.
How often should I practise this skill?
Short, focused practice is usually more productive than repeating the skill until exhausted. Work on one or two details at a time and stop while you can still maintain calm breathing and good control.
Do I need a swimming instructor?
Video lessons can clarify technique and help you prepare, but an instructor can see your individual movement, correct unsafe habits and adapt the progression to your current ability.
