This happens because your body is less dense than water. It is the very same reason why a helium filled balloon will float upward in air. Helium is less dense than air, and so the more dense air settles under the balloon and moves it up; the balloon is 'seeking' the surface of the air mass that it is floating in.
Another way of thinking about this: If you could measure out the amount of water that weighs exactly the same as your body weight, you will find that the volume of that water is less than the volume of your body. Same weight in a smaller volume-- that means the water is more dense than your body. The density of water is really called specific gravity, but the concept is the same.

NOTE: This turns out to be very useful as a way of measuring over-all body fat, or the Body Mass Index. Some people can be standing in 3 or 4 feet of water, exhale the air from their lungs as completely as possible, and have time to float down to the bottom of the pool and lay there for a moment before coming up for air. Others cannot do this, no matter how hard they exhale. The difference is the amount of body fat. body fat is less dense than muscle, so it works to keep the body at or near the surface.
What else can I help you with?
What is an example of floating?
If you lay on your back in water without moving, you will float.
How do you survive a rapid?
Lay on your back and float down. Once you hit calm water then get out of the water. Remember, you can only be in the water for 15 mins. before your body will shut down!! And don't die.
Do humans float if they lay flat on the surface of the water?
Yes, humans can float if they lay flat on the surface of the water due to buoyancy. When a person's body displaces enough water, the upward force exerted by the water (buoyant force) counteracts the weight of the body, allowing them to float.
Define supine float in swimming?
A supine float is floating in the water on your back with head above water.
Can chickens lay eggs under water?
No they cant, and even if they were to try the egg would float
How can a ship float if it is more dense than water?
A ship can float because shape allows more surface area in the water allowing it to displace more water, when an object (the ship in this case) displaces more water than its weight it floats, if it displaces less water it sinks (a rock for example). a good example of this is say you are at the pool when you lay flat on your back in the water you float however if you tuck into a ball you begin to sink.
What is your weight when float on water on back?
Your weight is the same on land as on the water.
How does a water tank float switch work to regulate the water level in a tank?
A water tank float switch works by using a buoyant float that moves up and down with the water level in the tank. When the water level rises, the float also rises, triggering a switch to turn off the water supply. When the water level drops, the float lowers, turning the switch back on to refill the tank. This helps regulate the water level in the tank automatically.
Can jeremejevite float on water?
Jeremejevite does not float on water.
Art Carney quote about floating on your back?
When the tides of life turn against you, And the current upsets your boat, Don't waste those tears on what might have been, Just lay on your back and float.
What will happen if a ball is pushed under water and then released?
It would simply float back to the surface!
What are the results of can water float on water?
Yes, water can float on water. This is because of surface tension, which allows objects with a lower density than water to float on its surface. Items like boats or water bugs can float because of this phenomenon.
