Why do divers enter the water feet first?
In this diving competition, divers enter the water feet first because of the high risk of head injury. The water stops the divers in less than a second and they rarely go deeper than 4 m.
What happens if divers return to the surface of the water too quickly?
Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. … But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage. In extreme cases, it can cause paralysis or death if the bubbles are in the brain.
How do divers enter the water?
From there a backward roll is the easiest and safest way to enter the water. In a larger boat, divers don fins standing up in a gangway or on a platform and enter the water feet first, with what we call a giant stride. If you jump in face first from a boat you risk displacing your mouthpiece and face mask.
Why do divers shower after each dive?
Why divers shower
“Divers shower in between dives typically just to keep themselves and their muscles warm,” he says. They usually rinse off in water that’s warmer than the pool. … air temperature on the pool deck may be a little chilly, so the shower can help keep muscles warm.

Why do divers enter the water with flat hands?

Why do scuba divers spit in their masks?
Decreasing the surface tension and creating a moisture film prevents fogging. … As a surfactant; saliva decreases the surface tension of the droplets. The water from the condensation does not mound up as beads or droplets but, instead breaks to form bigger droplets that just roll away into the mask.
