No, actually it's not a myth.

Grumpy McTrumpy

you are right about it not being a myth. It's total nonsense.

umd

You apparently have no idea how the body's temperature regulation works. People who overdress in the winter may sweat more under their heavy clothes but if the body is colder it doesn't need to sweat as much. Also many places tend to be humid in the summer and drier in the winter, and it is humidity that affects whether or not you notice the sweat. When it's hot and sticky you know you ate sweating because it doesn't evaporate as well.

I eat sweat, therefore need no bottles.

Indeed. On a typical summer day - Phoenix, AZ 110 degrees you only notice sweat when you're stopped at a light or going up a steep hill. Rocky Mount, NC 97 degrees you're dripping sweat non-stop.

Grumpy McTrumpy

all he has to do is try my experiment once and that nonsense will be dispelled rather quickly.

I can put out a fair amount of watts without a single fan on me when the room is 48. The same watts at 75 ambient temperature would have me sweating like a damn soaker-hose.

I do have an idea and I have done research on sweat rates in cold weather vs. warm weather. I suggest you take some time to do so as well.

How do you fit a 2-litre bottle in your cage?

carpediemracing 

I bring two bottles on almost all rides, regardless of what "Dog in A Hat" Joe Parkin's buddy told him. His teammate said to him "Why 2 bottles? We can always stop somewhere to get a drink. 2 bottles is for Americans." I paraphrase but you get the gist.

I've gone for 4-5 hour rides without taking a sip. I've also finished off 6+ bottles on the same route on a different day. I've felt idiotic at the end of a 5 hour ride without taking a sip but I get appropriately thirsty afterwards (and I understand the thirst reaction lags behind actual need).

In hot weather I often start 1 hour crits with 3 bottles (1 liquid in a cage, 1 frozen in a cage, 1 frozen in my pocket) and chug most of a 4th bottle just before the start. I rarely finish with any fluids left, and a lot of the time I find myself metering water for the last 4-5 laps.

Show your research.

Remove the effect of clothes and the body will not need to sweat as much to maintain it's temperature. It's simple thermodynamics.

Bottom line is some people overdress in the cold and that traps the heat in.

skol

usually intend on taking 2 on every ride but can usually only find 1 so just go with it

acaurora

I usually take only 1 on my normal group rides, especially given that the rides are fairly relaxed as well as the weather lately. I only take two whenever I know that either the weather will be very warm (i.e., summer), or if the ride I am going on is 1. (new to me + long... i.e., over 50mi) 2. Long in general (over 50mi) 3. Involves lots of climbing 4. Generally anything that seems that it will be very strenuous.

Bottom line is you have to figure out what works for you. Everyone deals with heat differently so it is pretty silly to try to come up with a general rule. I am a very heavy sweater and in the summer when the RH is 80% I can lose 5lbs on a 1.5hr ride that means 2 bottles for anything over an hour ride. In the winter it is not even close when the RH is <60% I will lose <2lbs so 1 bottle is sufficient. That is what works for me. I have come up short a couple of times and believe me I much rather carry extra water than deal with dehydration.

Don't make me describe the color of my pee.

I get it you are not arguing whether you need to drink when it's cold, but about how you sweat. It's too bad you had to go off on a tangent to start an argument rather then stick to what was being discussed.

umd

i didn't go off on a tangent or start an argument, I corrected false information. I responded to a post that said you sweat more when it is cold. That is a myth. I never said not to drink, I said specifically that you still need to pay attention to your hydration. I agree that hydration is often overlooked and underdone in the cold but there is nothing about cold weather that makes someone sweat more than hot weather except for potentially how they dress. Bottom line, keep hydrated and dress appropriately.

umd

And just in case it isn't clear, sweat more = drink more.

Look at the bold part and then go back and re-read my original post. The tangent obviously came from you either seeing what you wanted to see or you mis-reading what I wrote.

Camilo

gotta repeat this one for emphasis

umd

Ok, so go back... original post... you said "you are sweating as much, if not more, as in hot weather."

Yep, that's exactly what I thought you said. Are you denying now that you said you sweat more in cold weather than hot weather?

My reply that it's a myth was appropriate, and I stand by it. There is no tangent here, I replied directly to your words. There was no attempt to "start an argument", I simply corrected you.

As far as your conclusion, you said that to "use as much water in the cold as you would in the heat." My response was to pay attention to your hydration but not to automatically drink as much as you would in the heat. Notice I didn't say don't drink in the cold.

If you dress appropriately (not overdressing) in cold weather you will sweat less than in hot weather, and subsequently you won't need to drink as much. Now if you overdress you may end up sweating more, but that's not because of the weather, that's because of your choice of clothes.

Let's do a though exercise to try to get on the same page: If you go ride wearing shorts, a medium weight base layer, and no arm warmers, are you going to sweat more in 50 degree weather or 80 degree weather? 100 degrees? Assume similar humidity.

Now for some anecdotes. I did a race last summer that was stupid hot. It was well over 100F for most of it, and I've seen reports that put the high in the mid 100-teens. I super-hydrated in the morning after I got up, on my way to the race and immediately before the race, about 3 bottles worth. I started with two bottles and took a "feed" of a fresh bottle on each of the 6 ~11 mile laps. So 7 bottles in the 3 hours of the race. Immediately after I found a friend and drank 2 more bottles (of very refreshing icewater). I waited around for about an hour for the results during which I drank another bottle, then went and got a 24oz smoothie and drank another bottle on the way home. If you are keeping score that's like 14 bottles (numbers are approximate) and when I got home I was down something like 8 pounds (!). On the other hand I can go out and ride 100 miles on a cool day (say low 60s) and only drink a bottle over the 5 hours, come home and only be down about a pound.

So seriously, show your research that shows that " you are sweating as much, if not more, as in hot weather." I'm really interested in seeing your evidence that runs contrary to the laws of thermodynamics and any rational thought.

Let me get this straight, I wrote "...as much, if not more..." and you are now saying "Yep, that's exactly what I thought you said. Are you denying now that you said you sweat more in cold weather than hot weather?" yet you can't understand why I say you are either seeing what you want to see or that you mis-read?

I think it's clear you are simply seeing what you want to see and no matter what I say or post you will find some way to twist it into what you want it to be. The proof is there in black and white for all to see. Therefore it's clearly a waste of my time to discuss this further.

YOJiMBO20

This made no sense.

And it was a waste of time to discuss it further a while ago. But it was fun to read.

umd

you said that in cold weather you sweat as much, if not more, as in hot weather, right?

Where is the misread? You say sweat in cold >= sweat in hot, and I say sweat in cold < sweat in hot.

I understand exactly what you are saying, I'm just saying you are wrong.

The only way you could possibly sweat as much or more in the cold as in the hot is if you you are wearing too much.
