Flotation Features of Your Body
Let’s start with a basic principle of physics: anything with a higher density than water will sink in water. The human body is, by weight, roughly two-thirds water. This means your density is similar to that of water. Therefore, you shouldn’t have to do much, if any, work to float on top of the water.
That said, your body composition can affect your natural ability to float. Very generally speaking, men tend to have greater muscle density than women. People with greater muscle density, or very lean muscle (a very low ratio of fat to muscle fiber), will have a greater tendency to sink. So, if you are young, a man, or a very athletic woman, good mechanics and technique will help you a lot. Nevertheless, your body still wants to float more than it wants to sink.
Your lung capacity can also make a difference in how easy it is for you to stay on top of the water. People with a higher lung capacity will float somewhat more easily, for two reasons. First, they have a larger pocket of air in their chest. And second, they tend to have more oxygen circulating throughout their bodies. Oxygen is less dense than water, so the more oxygen you have in your body, the more buoyant you will be.
Now that you know why your body might be more or less inclined to float, here are three ways you can improve the way you float in water.
