Human physiology of underwater diving is the physiological influences of the underwater environment on the human diver, and adaptations to operating underwater, both during breath-hold dives and while breathing at ambient pressure from a suitable breathing gas supply.
The buddy may get into difficulty due to inattention or incompetence, and require a rescue that is hazardous to the rescuer. The buddy may get into difficulty and mishandle the situation or panic, creating an incident that is hazardous to both divers. Diving with a buddy is known to be competent and who can be trusted to behave responsibly. [62]

Hard hat diving is any form of diving with a helmet , including the standard copper helmet, and other forms of free-flow and lightweight demand helmets .
Manufacturers are continuously improving diving equipment to allow deeper, longer and safer diving operations, but the equipment still has ergonomic limitations and can exert significant stress on the diver: [1] Regulators require increased breathing effort. Protective suits restrict mobility.
The diving depth record for offshore diving was achieved in 1988 by a team of professional divers (Th. Arnold, S. Icart, J.G. Marcel Auda, R. Peilho, P. Raude, L. Schneider) of the Comex S.A. industrial deep-sea diving company performing pipe line connection exercises at a depth of 534 meters of sea water (msw) (1752 fsw) in the Mediterranean ...
It is designed for decompression diving executed deeper than standard recreational diving depth limits using trimix as a "bottom mix" breathing gas. There have been three iterations of UTD Ratio Deco, The latest as of 2021 is RD 3.0, which has less emphasis on deep stops than RD 2.0.
In deeper diving, the scrubber needs to be bigger than is needed for a shallow-water or industrial oxygen rebreather, to provide longer dwell time, because of this effect. At low temperatures the scrubber reaction will be slower, and may not remove enough carbon dioxide if the dwell time is too short.
Scuba diving therapy is a type of treatment that consists of a variety of scuba diving activities and exercises. Essential elements are increased body awareness , social bonding, and breathing techniques.
