    Dehydration

    At last! A biker subject upon which I can pontificate with some authority.

    Just to clarify that, I have about 2,000 hours as a glider-pilot.

    A glider is a mini-hot-house with wings. Dehydration is one of the biggest killers of pilots.

    The affects of dehydration are extremely subtle. You 'think' you're doing okay, whereas, when dehydrated, your mind becomes tunnel-visioned. Ergo, you see what you 'think' you should be seeing but, in fact, you're seeing what you 'want' to see.

    Dehydration is a lot like being pissed, except you don't get the buzz. All you get is the loss of focus.

    And around the next corner comes something you weren't expecting, your brain has more or less shut down, even though you 'think' it's still doing normal stuff, and poom! You're another statistic.

    But there's a rule of thumb you can use to avoid dehydration, but first allow me to assert, you simply cannot objectively establish dehydration. It just happens, and it happens at different rates for each person.

    You get to objectively consider it while laying in a hospital bed, or on the road, as you lay there with sundry folk poking you in an eye to see if you're alive. Or some gung-ho type like me who finds a piece of broken mirror to start performing the tracheotomy.

    The rule of thumb is this. Water in/water out. Question. How much in and where does it go?

    Answer. Lots in. And I'm talking litres per hour if you're in leathers or black gear.

    You should be swallowing enough water to allow you to sweat out a lot but still need a piss every two hours.

    If you don't feel the need for a serious piss within any two hours, believe me, you're dehydrated.

    In seriously hot conditions (Christmas/summer) you sweat like nine bastards. This sweat is body-fluid leaving you to join the great circle of life. Yet, as you ride at a reasonable speed, the passing wind evaporates the sweat.

    You 'think' you're doing okay cos you feel cool...in all senses of the word on a bike....Cool you may be, but unless you need a piss every two hours, then you might feel cool but your head is in a very dangerous space.

    At race and track-days (during summer) , given I know a lot about the affects of dehydration...If I don't want a piss after coming off the track from the last round, then I'm a danger to myself and all around me.

    There's a very technical explanation regarding dehydration, and loss of body-salts, etc, but just take the simple advice.

    If you don't feel like you need a piss every hour or so, on a really hot day, dressed in leathers, then drink more water till you do feel the need.

    Coffee and alcohol are diuretics; ergo they strip water from your system and, with it, the salts which are vital to your continued proper brain function.

    And so, when you stop for a double-shot Latte, enjoy it, but drink a litre of water before you saddle-up. You'll be amazed at how you still don't feel like taking a piss, two hours later.

    And remember, the cagers haven't the foggiest idea about dehydration, other than when they watch their tomatoes drying in a dehydrator.

    They sit in their cages, trying to ignore the screaming children, the nagging wife, the vile heat. Their brains are miles away from the task in hand.

    Two dehydrated motorists, (one on a bike, one in a cage) heading toward each other, even 50 Ks apart when the dehydration kicks in, are a fatality waiting to happen.

    You stay hydrated. You lessen the chances of becoming a statistic.

    Another glider pilot! That makes at least 4 of us on here.

    You are absolutely right about dehydration. On long rides I drink plenty of unsweetened fruit juice. Its not just the water loss, but also loss of trace elements through sweat that causes that the lack of co-ordination and degradation of reactions.

    Would gagging and generally feeling like you are going to barf all over your shiny new KBC be because of dehydration?

    I have a health condition which keeps me fairly lethargic but worst of all, keeps me hot which in turn makes me sweat it all out! I am investing in one of these http://www.cycletreads.co.nz/content...l&entryPK=2108

    They by no means 'stop' dehydration but they hold back the sweats and every person I have talked to who has them has sworn by them, especially for motocross when you're wearing yourself out in hot gear.

    I still have my older dririder jacket with support for a hydration pack and ties to hook it up into the helmet, invaluable on hot, hot, hot trips!

    Cool. Great thread, and certainly makes you think about fluid loss and the effect on your body. Particularly pertinent on a bike where air flow does tend to mask the effects of evaporation. Thanks!

    I'm currently working up in Sumatra and sweating buckets. It can be hard to keep up with the necessary water intake to compensate for this. I have had occasional trouble with headaches in the afternoon that I put down to dehydration. I have found a great product here called 'Pocari sweat', you have maybe seen in mocked along with other asian product like 'Cock soup'. Pocari is actually alot like powerade and designed to replace your sweat. The main advantage is that is doesn't have the enormous sugar content of similar western products. I have a can with lunch and continue to drink as much water as I can and it seems to work. You can probably get it in one of the many asian stores, supermarkets, dairies, delis etc.

    Nope. Just go with water-in/water out. You don't need the fancy, expensive drinks. You just need accesss to a tap to fill your water bottle.

    It was a honda bucket at the time wearing full 2 piece leathers with no fluids so it could explain it...could explain why i lowsided the next lap putting some "badges" on my leathers and a tar seal coloured scuffmark on my shiny new KBC with only about 30 mins in it

    Aaaagghh, discovered that stuff in Japan eeeeewwwww. (Sorry to be one of the mockers ). Despite knowing the purpose of it, I just couldn't get into drinking it. The other drink that is so popular there goes by the wonderful name of Kalpis water, which is pronounced like cowpiss water, so you can imagine that we didn't really take a fancy to that either!!

    Great thread and timely for the time if year.

    My missus is a long distance runner so she knows all about this but the fact we are biking and get the cool air can mask the real problem. Great advice mate and will heed accordingly.

    Fanx for the other advice re the corromandel as well.

    Great post. I did a Christchurch to Akaroa and return trip in October. All of the gear on and 27 degrees. Didn't have much to drink. Didn't take a piss for about four or five hours. I knew I was dehydrating but not to the extent that I was. I spent the next day feeling like shit and I knew why. Lesson learned.
