	~~'''~~Underwater Diving''' is the practice of descending below the water's surface to interact with the environment. Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not naturally adapted to the underwater environment, but have developed different methods to extend the depth and duration of their dives.		== Underwater Diving ==

	~~==Types of Underwater Diving==~~		Underwater diving is the practice of descending below the water's surface to conduct various activities, such as exploration, research, or recreation. It encompasses a range of techniques and equipment, from simple breath-hold diving to complex [[saturation diving]] operations.
	Underwater ~~diving can be categorized into two main types: [[recreational diving]] and [[professional diving]]. Recreational~~ diving is ~~done for enjoyment and has a number~~ of ~~disciplines, including [[scuba diving]], [[freediving]], [[snorkeling]], and [[spearfishing]]. Professional diving, on~~ the ~~other hand~~, ~~includes diving roles~~ such as ~~[[commercial diving]]~~, ~~[[military diving]]~~, and [[~~scientific~~ diving]]~~, which are undertaken for reasons related to employment or research~~.

	===~~Scuba Diving~~===		=== History ===
	[[~~Scuba diving~~]] ~~is a form~~ of ~~underwater~~ diving ~~where~~ the ~~diver uses~~ a ~~self-contained underwater breathing apparatus (scuba) to breathe underwater~~. ~~It is perhaps~~ the ~~most well-known form~~ of ~~recreational~~ diving.		The history of underwater diving dates back to ancient times, with early divers using [[reed]]s to breathe underwater. The development of diving bells in the 16th century marked a significant advancement. In the 20th century, the invention of diving, allowing divers to explore the underwater world with greater freedom.

	===~~Freediving~~===		=== Types of Diving ===
	[[Freediving]] involves diving without breathing apparatus, relying on the diver's ability to hold their breath until resurfacing. This practice is ancient and has evolved into competitive sports and is also used in underwater hunting.

	===~~Commercial~~ Diving===		==== Recreational Diving ====
	[[~~Commercial~~ diving]] ~~involves diving as part of one's job~~, often ~~related to underwater construction~~, ~~salvage~~, ~~or inspection work. Commercial divers may use a variety of diving equipment~~, ~~including surface-supplied diving systems~~.		Recreational diving is primarily for enjoyment and includes activities such as [[scuba diving]], [[snorkeling]], and [[freediving]]. It is often conducted in warm, clear waters and involves exploring coral reefs, shipwrecks, and marine life.

	==~~Physiology of~~ Diving==		==== Technical Diving ====
	~~Underwater~~ diving ~~subjects the body to increased pressure~~, ~~leading~~ to ~~various physiological effects~~. ~~The most significant of these is the increased pressure of gases~~, ~~leading to the potential for~~ [[~~decompression sickness~~]] ~~(DCS) if not managed correctly~~. ~~Divers must also manage the potential for~~ [[~~nitrogen narcosis~~]] ~~and oxygen toxicity~~.		Technical diving involves more advanced techniques and equipment, allowing divers to go deeper and stay underwater longer. It includes [[cave diving]], [[wreck diving]], and [[deep diving]]. Technical divers often use mixed gases like [[trimix]] or [[heliox]] to manage the risks associated with deep dives.

	===~~Decompression Sickness~~===		==== Commercial Diving ====
	[[~~Decompression sickness~~]] ~~occurs when dissolved gases (mainly nitrogen) come out of solution in bubbles~~ and can affect virtually any area of the body, including the joints, lungs, heart, skin, and brain. Divers prevent DCS by following decompression schedules or using dive computers to monitor their exposure.		Commercial diving is performed for industrial purposes, such as underwater construction, inspection, and maintenance. It often involves the use of specialized equipment like [[diving bells]] and [[saturation systems]].

	==Diving ~~Equipment~~==		==== Military Diving ====
	~~The equipment used in underwater~~ diving ~~varies depending on the type of diving and the conditions. Basic equipment~~ includes ~~a mask, fins~~, and~~, for scuba diving, a diving cylinder and regulator~~. ~~More specialized equipment can include dry suits or wetsuits for thermal protection, dive computers for monitoring decompression limits,~~ and ~~underwater navigation tools~~.		Military diving includes operations conducted by naval forces, such as [[explosive ordnance disposal]] and [[underwater demolition]]. Military divers are trained to perform in various environments and conditions.

	==~~Safety in Diving~~==		=== Equipment ===
	Safety is a paramount concern in underwater diving. Divers are trained in emergency procedures, including buddy diving practices, and the use of safety equipment such as [[dive flags]] and surface marker buoys. The use of dive tables or dive computers is essential to plan dives within safe decompression limits.

	==~~Environmental Considerations~~==		==== Breathing Apparatus ====
	~~Underwater diving offers~~ the ~~opportunity to observe marine life and environments firsthand. However, divers must be conscious~~ of ~~their impact on aquatic ecosystems~~. ~~Practices such as good buoyancy control~~, ~~not touching marine life, and avoiding the disturbance of sediments~~ are ~~important to minimize the environmental impact of~~ diving.		Divers use different types of breathing apparatus depending on the type of diving. [[Scuba]] (self-contained underwater breathing apparatus) is the most common for recreational diving, while surface-supplied systems are used in commercial diving.

	==~~See Also~~==		==== Diving Suits ====
	* [[~~Underwater environment~~]]		Diving suits protect divers from cold water and hazardous environments. [[Wetsuits]] and [[drysuits]] are commonly used, with drysuits providing better insulation in cold conditions.
	* [[~~Diving physics~~]]
	* [[~~Diving medicine~~]]		==== Other Equipment ====
	* [[~~Diving hazards and safety~~]]		Additional equipment includes [[fins]], [[masks]], [[buoyancy compensators]], and [[dive computers]]. These tools help divers navigate, communicate, and monitor their dive profiles.

			=== Safety ===
			Safety is a critical aspect of diving. Divers must be aware of potential hazards such as [[decompression sickness]], [[nitrogen narcosis]], and [[barotrauma]]. Proper training, equipment maintenance, and adherence to dive plans are essential for safe diving practices.
