Underwater diving is the human practice of voluntarily descending below the surface of the water to interact with the surroundings, for various recreational or occupational reasons, but the concept of diving also legally extends to immersion in other liquids, and exposure to other pressurised environments.

Temperate water is water cooler than tropical, and warmer than "cold water". For diving purposes this can be considered the temperature range in which a full wetsuit is acceptable thermal protection for most divers for most diving activities. The range of 10 to 25 °C (50 to 77 °F) could generally be considered temperate water for diving.
Much of the science covering underwater habitats and their technology designed to meet human requirements is shared with diving, diving bells, submersible vehicles and submarines, and spacecraft. Numerous underwater habitats have been designed, built and used around the world since as early as the start of the 1960s, either by private ...
An immediate obstacle to human activity under water is that human lungs cannot naturally function in this environment. Unlike the gills of fish, human lungs are adapted to the exchange of gases at atmospheric pressure. Any penetration into the underwater environment for more than a few minutes requires artificial aids to maintain life.
The study also concluded that it would be impossible to eliminate all minor contraindications of scuba diving, as this would result in overwhelming bureaucracy and bring all diving to a halt. [174] Human factors in diving equipment design is the influence of the interaction between the diver and the equipment on the design of the equipment on ...
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 science of underwater diving includes those concepts which are useful for understanding the underwater environment in which diving takes place, and its influence on the diver. It includes aspects of physics, physiology and oceanography. The practice of scientific work while diving is known as Scientific diving.
Remotely operated vehicles and autonomous underwater vehicles are also used for the exploration of flooded caves, as they do not risk human life and have a far greater operating depth range. [ 9 ] Underwater cave mapping is complicated by both a lack of access to the surface for GPS positions, darkness, with short line-of-sight, and limited ...
