DRINKING ON THE JOB!! (Keeping yourself Hydrated)
Keeping yourself hydrated while diving is one of the most basic and important parts of diving that I just can’t stress highly enough to my friends and SCUBA students!! You may ask your self why?! I’ll tell you here:
Being dehydrated can affect you in many ways while diving and the reason I feel is most important is that it can lead to DCI!But not only that but cramping and a lot of discomfort.
The first way that diver’s become dehydrated is through WATER itself! The cooling effects of water do this to you. To save heat your body reduces the blood flow to your extremeties,which basically act like radiators.With less blood volume in your arms and legs means that your "inside core" will have this extra fluid, where the pooling triggers your kidney’s to get rid of the "excess" water, which your body thinks you have.
Your second way you lose water is through the simple act of breathing! Since water vapour gums up engines and such air compressors remove most of the water that is in air. The result being that most breathing gases be it air, EANx, or Tri-mix have about as much water in them as Kansas in a dry spell. Since it’s so dry each breath that you take from your tank picks up moisture in your lungs and expells it with every breath. So every time you breath you lose a little more moisture.
You can also lose lose a lot of water before your dive which is the third way you can become dehydrated. If you sweat a lot before your dive your body is obviously giving up some of it’s water content. And especially in "tech" diving this is very important as you need more exposure protection for your dive. Putting on your exposure suit in a hot climate, the worse being a HOT DRY CLIMATE, (Drysuits here folks), such as California, the Sinai, Missouri!! You get the point, hot air and cool water!!
And finally your diving lifestyle affects your bodys hydration. Most people tend not to drink enough NON- CAFFIENATED, NON-ALCHOHOLIC fluids before a dive. Caffiene makes you urinate,(pee a lot), and so does alchol the night before,(Especially in vacation mode, really bad on an all inclusive!! :) :)
HERE ARE 5 WAYS TO KEEP YOURSELF DIVING AND NOT DEHYDRATING!!!
1) DRINK BEFORE THE DIVE!!!
Yup, right up to the last minute before you hit the water! And you "tekkies" should make a bottle of water part of your standard gear bag!!!
2) DRINK WATER!!
You want to minimize the amount of caffiene your body has, (see peeing a lot, above). A cup of coffee won’t kill you, but do you really want to risk it with a pot of it before you dive?? Fruit juices, sport’s drinks like Gatorade may have a great taste, but your body absorbs plain old water faster than anything!! (Except maybe an IV, but if you’re that sick you shouldn’t be diving today!!) .
3) DON’T BE AFRAID TO USE DIAPERS OR A RELIEF ZIP IN YOUR DRYSUIT!!!
Some people don’t drink enough before a tek or deco dive thinking they’ll have all of their hang time with their legs crossed. If you can relieve yourself,(P),you won’t be afraid to guzzle right up until the time you jump in for your dive!!
4) DRINK DURING THE DIVE!!
Yes this does take some practice, so try it in confined pool space before you venture out to "Big Blue". And don’t count on drinking the water you’re diving in! YUCK!! Drinking underwater isn’t hard, but it’s not a task taught in your Open Water class. The easiest way to do this is to use a collapsable container, (like a wine skin). If you use a collapsable bottle, put it to your mouth, squeeze in a bit and swallow, keeping it in your mouth, as when you exhale it will re-inflate the bottle making it easier for your next sip!!
Oh yeah, it’s probably best to AVOID eating underwater!! :)
5) DRINK AFTER THE DIVE!!
After a long dive it take’s awhile for your body to feel warm even in the hottest climate, but it doesn’t mean your body isn’t thirsty! So drink up!! Avoid alchohol, unless it’s your LAST dive of the day!! It’s fine to have a beer with the buddies on the way in.
Hope you find my article amusing but informative! That’s what diving is all about!! HAVING FUN!!!
