is an 8/7 wetsuit inappropriate for warmer water?

[mjatkins]

It was simply trying to answer YOUR question, which apparently you no longer care about.

You're welcome.

Would you mind clarifying. I have gone back through the posts, and from what I can find my question that prompted you to start interacting with me was "how is this possible?" It was asking how it is possible for the water inside someones wet suit to be heated up to a higher degree than the pee that comes out of them at body temperature. If that is the question you are referring to, I have yet to see a convincing answer. Or are you referring to a different question?

Same question. Yes. The mechanism was explained. Some folks understood. You got snarky. I'm done trying. Maybe someone can explain it to you.

Google "overheating in a wetsuit" - one of the results on the first page is a book "SCUBA DIVING EXPLAINED -Questions and Answers on Physiology and Medical Aspects of Scuba Diving."

Would you mind posting a link to this page, or send it to me in a PM. I have googled "overheating in a wetsuit" and can find no reference to the link you mentioned. In fact i can't find anything that references overheating in a wetsuit, except for pages about triathletes. There is also one page of "glossary" terms that mentions hyperthermia, but makes no mention of how it could occur.

The Glossary is the glossary of the book I mentioned in my post. I care not to purchase it, but the phenomenon would be described in the book. And since the book is on scuba diving.....

Would posting the question in the Scuba Medicine forum and hearing from some Docs help you out?

If you have little water in your suit you can very well heat it above body temp, maybe not by much, but at least to body temp.
This is how people overheat, the water in their suit it not flowing in or out, it's stagnant and heating up to where it longer provides the cooling conductive effect at a fast enough rate.
This is especially true if you're doing strenuous work on the surface and dumping heat from your body, which in turn is being trapped by wetsuit, hood, and booties.

With reference to the OP, if there's no hood and loose suit, no problem.
If it's a tight suit with good seals that keeps little water from moving out once it's in then he may have a problem. Add a hood into the mix and that problem could escalate.
Overheating under water if next to impossible, but surface swims and SI are where the problems are likely to occur.

That's my 2 cents

ok, we can just let u go on and ignore everything, over state the effect of water, and ignore the human body being able to produce heat above body temperature (metabolic heat is what makes us able to be warm blooded, warm blooded meaning we can heat up our bodys past that of the surrounding temperature) and then call our arguements flawed, i love to hear ure evidence about why there flawed by the way.

Certainly, if you know how to get a doctor who is well versed in diving science to come forward and settle this, I think that would be a wonderful addition to this conversation. I look forward to it.

Have you read the book? Just curious.

Now, that sounds reasonable. Under certain circumstances it may be possible to heat up water to our own body temperature. Above body temperature sounds iffy, and I believe that in 75 degree water, as was the pretext of this discussion, it sounds extremely suspect.

Just curious, when you say "that's my 2 cents", do you mean this is your opinion, or do you know it to be a fact?

Thanks

I mean it is based on my opinion from what I've experience. But I have no scientific numbers to back it up.
I have gotten hot and uncomfortable in 65F waters wearing a 4/3 with 7mm jacket, which is why I believe it is possible to be uncomfortable in a 8mm in 75F waters.

My question for you is not weather or not we can heat up our bodies past the surrounding temperature, it is weather we can heat up the surrounding temperature past that of our body.

I am not trying to ignore anything. I am looking for evidence greater than your speculations. If you are offering anything of evidentiary value, it haven't yet recognized it as such. Perhaps site your sources. Since you are making this assertion, I have to believe you have some evidence for it. Obviously it will be much easier for you to prove that your evidence exists than it would be for me to prove that your evidence does not exist. I don't know what your evidence is.

If on the other hand this is nothing more for you than a penis measuring competition, then I am happy to let our discussion end here.
