High water pressure (at depth) causes nitrogen to be dissolved into the bloodstream. Ascending too fast can cause the nitrogen gas to 'bubble out'. These bubbles can cause the diver to suffer a heart attack - with possibly fatal consequences. If a diver rises no faster than the air bubbles they're breathing out, it gives the body time to dispel the nitrogen through the bloodstream and out through the lungs.

Divers fall backwards from a boat because it is often the easiest way to make a deep water entry from a small boat or rib.
The deeper the diver goes, the higher the pressure is.
Hypobaric conditions occur when divers ascend to higher altitudes or depths, leading to a decrease in pressure, which can cause issues like decompression sickness. Conversely, hyperbaric conditions are experienced when divers descend into deep waters, where increased pressure can lead to nitrogen narcosis and oxygen toxicity. Proper training and adherence to safety protocols, including gradual ascent and using mixtures of gases, are essential to mitigate risks associated with both hypobaric and hyperbaric environments. Understanding these conditions helps divers safely explore deep-sea environments.

Free divers do but scuba divers do not need to. Scuba divers take their air with them and would have no need to hyperventilate.
