How do divers dive and float freely in the water

Divers are influenced by gravity and buoyancy under water. When the two forces are equal, the diver keeps balance in the water and can be suspended in the water, neither rising nor falling. When they reach this state, they can go up and down freely by kicking the flippers or controlling the buoyancy to control the inflation and deflation of the vest.

Diving should be a hard downward stroke, not a natural sinking. It's the same as swimming forward, only in a downward direction. If you are on the water, first jump up to make your body out of the water, then use the falling speed to immerse your whole body in the water, turn around quickly, put the water down with your hands, and pedal the water. Generally, you can dive more than 3 meters after swimming for three or five times.

Precautions:

Add more water before diving. Because the compressed air breathed during diving is filtered to protect diving equipment from oxidation, it makes people feel dry. Moreover, every time the regulator breathes such dry air, it will consume twice as much water as normal breathing, which will increase the loss of water in the body in actual consumption.

Don't drink. Alcohol is a diuretic, which inhibits the release of some hormones that control water in the body. But that doesn't mean you can't drink, or drink less, enough is enough.

People's Daily Online-China Navy divers left the cabin at 330m underwater, creating a saturated diving record.
