He thinks by hyperventilating he can stay under the water longer

Hypervenilating removes extra carbon dioxide from the blood.  Our urge to breathe is not driven by lack of oxygen, but by extra CO2 building up; this also affects blood pH, as it forms carbonic acid, so low pH stimulates breathing, too.\n\nThus, the person can hold their breath longer, after hyperventilating.  he / she will not be forced to surface to breathe, to relieve the urge to remove more CO2.\n\nHowever, they will have disturbed their blood pH, which can cause the brain to malfunction, leading to loss of muscular control, and to drowning.\n\nThey might get low on oxygen, too.  Normally, we carry plenty of oxygen in our bodies; even the air we breathe out has plenty of oxygen in it, and can be forced into the lungs of an unconscious person, in "mouth to mouth resuscitation".  IRC the proper name for this is "expired air resuscitation" but I am not sure.

I would suggest that you stop running and investing more time into your swim training. Although swimming involves your cardiovascular system, there is a whole lot more involved in swimming than breathing. If you are not comfortable in the water, your body will tense up. This anxiety often results in having difficulty breathing. \nWork on improving your swim strokes. You could be exerting so much unnecessary energy that you exhaust yourself. Being as hydrodynamic as possible helps. Be streamlined. Your strokes and kicks should be efficient. There is a lot more to swimming than just getting from one point to another in the water.\nYour comparison is like saying that Tiger Woods can hit the golf ball so he should be good in baseball.

Water, being denser, takes heat away from your body at a higher rate than air at the same temperature.

I'll try and bay pacific but you sea it shore is difficult. He's out on his own from what i can fathom, aegean quickly, needing an outlet when his hands are tide. He may hit the rocks but will be fine when his Gal apagos waves to him.

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...

That's just too weird. He should see a doctor;  his peace of mind is reason enough.

Swim under the water.  That builds up more endurance.  Go side to side in the pool.  You can probably go one way without taking a breath.  You definitely need goggles for this. Underwater is often the fastest way because there is less turbulence.

breath deeply and slowly \njust imagine your sitting by a river and you can hear the water running down the stream

Ya, the cold is the body attempting to fix itself.  Just keep him warm, water is gold, all he can handle and just be there for him.

His latest stunt is to break the world record for holding his breath underwater. The old record is 8 minutes, 58 second. Blaine is shooting for 9 minutes.
