On this threads the need to drink is well reported, but he seem that must of the divers drink water... just plain water!
I'm not a doctor, but I use to be a mountain guide, and for 7 years see drink all sorts of weird stuff and they effects. At the mountain school you will get more than 20h on the subject on each of the guide levels. During the entry tests (marathon like but in mountains, with weighted backpacks and timed) I've been able to see the performance of each well know participant (the same people year after year) in function of they drink... four main groups:
-Don't drink enough.
-Drink plain water.
-Drink a complemented drink.
-Drink too much (normally plain water).
Plain water have the inconvenient to need to be digested: your body need to complement it with minerals until the right concentration to enable your body to incorporate it to the blood stream. This, added to sweating and pee will affect your blood composition along a non continue curve, and by then all you body chemistry affecting your performance. On the worst case you can get a water intoxication (talk a bout that at the end) leading to grave disorders.
On the other side complemented drinks (isotonic or hypertonic) have dosed levels of solutes (270-330mOsm/kg iso and + for hyper that normally include salts and carbohydrates. Because non or little digestion is needed, is little effort for the blood stream to incorporate your drink. Be balancing your body losses (sweat and pee) enable a optimum body chemistry... good for your performance!
The carbohydrates on the drink reduce the pressure and balance your body energetic systems. Helps to keep the head clear after prolonged efforts and a prompt recuperation (hyper for recuperation).
Water poisoning come from an imbalance between the intercellular and interstitial fluids. The main protagonist are potassium and sodium and a couple of hormones like ADH (antidiuretic H). Is a long dissertation I will avoid, but the main factor for the imbalance seem to be the loss of sodium by sweat and a hydration based on plain water (no aport in sodium).
The interesting part about the imbalance is that the symptoms include neurological disorder and a loss of blood volume.
I realize that mountain activities at not comparable to diving, but on the other side diving is a delicate balance of the body chemistry, and that's why I'm interested to know what are you drinking!
Please, from beginners to athletes... tell us how you drink; why, what, how and amounts.
Please, people with knowledge... give us your opinion.
