We're taught to never hold our breath on ascent, no matter if it's an out of air emergency ascent situation or a normal ascent to the surface. The last breath we take in, at depth , grows in volume as we ascend. If we didn't constantly breathe with that all important exhalation, air in the aveoli (air sacs) of our lungs would grow in volume to the point they popped. You now get to drown in your own blood. \n By never holding out breath, we keep the pressure differential down to a minimum between ambient and internal.\n As for taking a deep breath before going down, it doesn't matter. We breathe at a normal rate, just like you are now and as long as we're not over exerting ourselves, that really doesn't change.\n\n Lol, diver dude, some really far out answers in there,eh?

breath. air is the wrong answer because it doesn't make sense that a man can hold air for long.

Navy Seal.. hands down.  I come from a long line of Army men... and we're very "sink navy" if you get my drift... but everyone admits that the Seals are the toughest.

Even though he did not break the world record, I think what he did was awesome. How many people can say that they can 1st live underwater in a fish tank for 170 some odd hours straight--then (without resting, eating or anything)become chained and hold your breath and remove the chains at the same time. Plus staying underwater for over 7 minutes. That guy is amazing. He definitely didn't fail in his task, he just didn't get as far as he wanted to go.

Competitive free diving, often referred to as "apnea", is generally broken down into three categories; static, dynamic, and depth, with male and female records recognized in each category:\n\nStatic Apnea is timed breath holding and is usually attempted in a pool. \nDynamic Apnea is underwater swimming for distance and has sub-categories for swimming with and without fins. This competition is usually held in a pool. \nThe depth category has four sub-sections:\n\nConstant Weight competition is for self-propelled maximum depth, no weights or lines are allowed. This category is also divided into sections for fins or without fins. \nFree Immersion competition is for self-propelled ascent and descent along a line and is for maximum depth. \nVariable Weight competition uses a weighted sled for descent and divers ascend by pulling themselves up along a line. \nNo Limits competition allows the diver to descend with a weighted sled and ascend with a buoyancy control device, usually an air filled bag with a tether. The world record for the "No Limits" category of competitive free diving is held by Austrian diver Herbert Nitsch. On 2 October 2005 he dived to a depth of 172 m (564 feet), off the coast of Croatia in the Adriatic Sea; surpassing the previous record set by Loic Leferme by 1 meter. The current women's record is held by Tanya Streeter, who dived to 160 m (525 feet) on 17 August 2002. The unofficial record is held by the late Audrey Mestre (170 m) wife of legend Francisco “Pipin” Ferreras; she drowned whilst trying to set a world record of 171 m (561 feet). The unofficial record for men is held by the Belgian diver Patrick Musimu who dove to 209 meters (686 feet), in training, in summer 2005. \nOfficial World Records as of 2006-06-06 (AIDA)\nConstant Weight, women: Natalia Molchanova (Russia), -86 meter.\n\nConstant Weight, men: Martin Štìpánek (Czech Republic), -108 meter.\n\nConstant Weight, women, without fins: Natalia Molchanova (Russia), -55 meter.\n\nConstant Weight, men, without fins: Martin Štìpánek (Czech Republic), -80 meter.\n\nStatic Apnea, women: Natalia Molchanova (Russia), 7m30s.\n\nStatic Apnea, men: Tom Sietas (Germany), 8m58s.\n\nDynamic Apnea, women: Natalia Molchanova (Russia), 200 meter.\n\nDynamic Apnea, men: Tom Sietas (Germany), 212 meter.\n\nDynamic Apnea, women, without fins: Natalia Molchanova (Russia), 131 meter.\n\nDynamic Apnea, men, without fins: Tom Sietas (Germany), 180 meter.\n\nVariable Weight, women: Tanya Streeter (USA), -122 meter.\n\nVariable Weight, men: Carlos Coste (Venezuela), -140 meter.\n\nNo limit, women: Tanya Streeter (USA), -160 meter.\n\nNo limit, men: Herbert Nitsch (Austria), -172 meter.\n\nFree Immersion, women: Natalia Molchanova (Russia), -80 meter.\n\nFree Immersion, men: Martin Štìpánek (Czech Republic), -106 meter

You have to hold your breath and keep your eyes open or wear goggles.\nPut your head down into the water and put your feet up in the air out of the water. It is easy if you can swim under water. Learn that first.

like all natural things there is a resource of oxygen stored in our boby in form of water... if the body is short of oxygen the body tries to convert water into oxygen thus stop from dieing... \n\nwhen you hold your breath initially there is a shortage of air in the body you get unconscious during this period the body starts to convert some amount of water into oxygen... and waits for our body to get external air... \n\nthis is a slow process and if your body is not strong enough to resist... then you can even die immediately...

Sietas also holds the current world records in static apnea of 8 minutes and 58 seconds submerged in a pool without breathing, set on December 12, 2004.\n\nDavid Blaine recently attempted to break the record. He just came short, doing 7 min. 8 secs.\n\n3 mins. is considered very good for freediving spearfishing.\n\nHope this helps.

try drinking water upside down.  You can also hold your breath and chug water at the same time.

It is definitely possible to cry under water, especially if you are using scuba equipment.  Without this equipment, it would be difficult to carry out the normal crying process as sniffling and panting, which are a normal part of the crying process, could not happen.

You are gonna get a lot of answers saying to hold your breath, but that only works sometimes and not with every person. Try holding an ice cube to your throat for about 20 to 30 seconds. Also try holding your nose while you take big gulps of water.

The world record is around 115 feet for a head-first dive.  I have no idea how much more you could do if you went in feet first.

Most people who drown do not have water in the lungs due to a bronchospasm that shuts off the windpipe. He would not have water in the stomach either, because swallowing requires peristalsis through the espophogus. \n\nIam sorry for your loss.

Functionally, fetal hemoglobin differs most from adult hemoglobin in that it is able to bind oxygen with greater affinity than the adult form, giving the developing fetus better access to oxygen from the mother's bloodstream. Although this makes fetal hemoglobin bind oxygen more efficiently, I'm not sure that is why infants can withstand hypoxia better than adults.\n\nInstead I would propose the mammalian diving reflex. Submerging the face into water causes the mammalian diving reflex, which is found in all mammals (including humans, although it is less pronounced), but especially in marine mammals (as, for example, whales and seals.) This reflex puts the body into oxygen saving modus to maximize the time that can be spent under water. The effect of this reflex is greater in cold water than in warm water, and includes three factors:\n\nBradycardia, a reduction in the heart rate (of up to 50% in humans). \nPeripheral vasoconstriction, a decrease in blood flow to the extremities, in order to increase the supply of blood and oxygen to the vital organs, especially the brain. \nBlood shift, the shifting of blood to the thoracic cavity, i.e. the chest between the diaphragm and the neck to avoid the collapse of the lungs under higher pressure during deeper dives. \nThus, both a conscious and an unconscious person can survive longer without oxygen under water than in a comparable situation on dry land. Children tend to survive longer than adults when deprived of oxygen underwater.\n\nThis reaction is similar to the body's reaction to cold water dousing and might be related to temperature biofeedback.
