    So today it is 90+ degrees out and I went for a bicycle ride.

    Riding went well at first, but then I stopped sweating. Got light headed and heard a weird tone in my ear. I have a feeling I was very close to passing out. Lucky for me I brought enough water and my half way point was a Subway. Where I could sit in the AC and eat a BMT and drink lots of water.

    I guess my point is hydrate guys.
    And
    Anyone know how much liquids the body can go through in a day?


    BTW, Looking back I can see I was not hydrated when I left the house, but it didn't feel that way. I am tempted to force an extra liter of water down before I leave the house. Worst case scenario is I have to pee myself somewhere along the way.

    I was watching a show about Spec. Ops. on History Channel (or one of the similar stations). They had one guy sweat out something like 2 gallons in an hour or two.

    I don't do much at work but I DO make sure that I'm acclimated to hot weather: I deprive myself of a/c during workdays and only on Sunday afternoon in the truck. I do have an a/c on when I sleep at night.

    On a good 100+ degree day, I'll easily go through two gallons of water. I usually drink a gallon on any given day.

    Sugar/HFCS and caffeine will help to dehydrate you too. I only drink water after my morning coffee and evening whisky.

    You have to maintain your salt level and hydrate too. The body can intake 8 ounces of fluid every 20 minutes. Gatorade is better than water because it has salt in it from what I have heard. I am glad you are ok but you did describe heat exhaustion. I have been close too and it is not fun.

    I think air conditioning has screwed us all up to some point. Lets face it, the sun has always been there and most ppl thoughout history have managed not to fall over dead from it. Ppl seem like they just can't take even fairly mild summer heat these days. I think it is the air conditoning.

    I too only drink water throughout the day, excluding my two cups of coffee in morning and my evening glass of Irish Whiskey. Seems to work out well for me.

    The wife and I have gone through as much as 30 water bottles of H2O and sport drink in a days ride.

    On RAIN '07, it was a million 2 degrees out, we carried four 32oz water bolltles on the bike, plus we both had 100oz camel backs. it's 156 miles, all in one day, in July. There are 3 offical sag stops, and a couple unofficial.. we used 5 that year, and were near out of fluids at EVERY stop. Close to 7 gallons EACH that day.

    Some years the weather isn't to bad, some years... Out of 7 attempts we have 4 official finishes. One non-official, over time limit, but made the whole ride.

    EDIT to add, many if not most, RAAM riders and such actually use a cycloputer with a timer function to remind them to drink every 10-15 minutes.

    Getting dehydrated can really suck. It can go the range of just feeling lousy (like the OP described) to vomitting to passing out to death.

    It is important to hydrate prior to, as well as during, as well as after physical exercise. And a great point was made above about replacing sodium. Taking this a step further, there is a product called 'Ionic Fizz' that you can get at a heath food or sports nutrition store (or Amazon or other net sites). It has calcium, magnesium and potassium in additon to some other nutrients. During the day, and particularly prior to and during a workout I will mix a scoop of Ionic Fizz and a scoop of the Gatorade power together with water (the powder Gatorade is cheaper in the long run). This replaces my H20, my sodium, electrolytes and the other nutrients the brain/body needs to maintain level. Particularly the calcium/magniseum/potassium as this will help prevent cramping.

    The Ionic Fizz comes in different 'berry' flavors and is tasty. Since it is a powder, and since Gatorade can be in a powder it is easy to put some in a zip lock back and put in the BOB or camping back for camping/hikes/emergency situations. It is light and doesn't take up much room. Put a little plastic measuring spoon in the bag and you're all set.

    Goes a LONG way towards keeping you hydrated properly.

    In my 15 years of search and rescue in the Sangre de Christo Mountains of Northern New Mexico, in the summer and usually above 11,000 feet, our rule was if your urine is clear your are OK but if it starts getting a dark color, you are in trouble.

    Most of us would drink 2 quarts of water and then 1 quart of Gatorade (and repeat) to replenish the chemicals, especially salt.

    There is a possibly fatal condition called hyponatremia, where the hiker is fully hydrated but is exhibiting the symptoms of volume shock (which most of you call heat exhaustion). The problem is that the hiker has washed out all the sodium in his/her body and has not replenished the salt.

    The mortality rate of volume shock and hyponatremia is 80%, irrespective of treatment. So, be careful out there.

    Biking can be deceptively dangerous. The sweat wicks and the breeze makes it feel cooler than it is. But the core temp can definitely rise to dangerous levels, especially if you are not fit.

    One more question...

    If I couldn't get to someplace with AC, what would have been the best course of action.

    I had water, could I have soaked the sweat band in water.
    I could have pored some water on my head.
    There was a creek a few miles away. Assuming I could have gotten there, I could have laid down in the creek.

    My doctor told me that my chest pains after working in the heat all day a couple of months ago were from an elecrolite imbalance and got on me about drinking a gatoraide when I did something like that again. Good and timely post.

    Wet towel on the back of the neck will do it.

    My Grandfather always said NEVER to pour ice water over your head. I know you said water but it reminded me about the ice water. He was like a 3rd generation farmer so he knew a thing or 2 about the heat. Always said it could cause death.

    I am guessing I would have gone into shock if I had done that.

    Having been stationed in 29 Palms CA, training and deploying to Iraq twice. I've seen a few heat related casualties.

    Find shade. Lay down. Cool as best you can head, chest, armpits, & groin area. NOT cold water, cool water, or any water. You're trying to lower your core temp, not send yourself into shock.

    Chugging more water at this point helps nothing. You're better off dumping it on yourself and sitting in the shade for 20 minutes to cool down. Sip water. Or better yet, something with the 'electrolyte mix'.

    Think your work is hard at 90+ degrees? Try it with 40-60 lbs of gear, all day long.

    People also need to know that for their dogs if they run with them. I lost a dog years ago because they had plenty of water but not enough salt. I also got sick and you were right about the color of the urine. That taught me a lot about the dangers of not being hydrated properly with sodium too.
