Is our body waterproof?

The answer to your first question is - no, not entirely. The answer to your second question is - it does, that's why your skin gets "puckered" when you are in the bath for too long.\n\nThe skin has pours that open and close, when you are hot these pours open and you often sweat, this is also how you flush some toxins and bacteria from your system, which is why hot baths are good with mineral oils. It's also one of the dangers of showering in chlorinated water, as the chlorine can seep through the pours of your skin, and slowly poison you.

Thats a mixed and complex question. you first have to look at why you sweat.The body uses some or all of these four processes: radiation,conduction,convection and evaporation to offset and restore normal temp. ( 97.7-100.5 F) Recptor cells in the skin resopnd to change by sending nerve inpluses through the cerebral cortex to the hypothalamus\n( part of the Endocrine system). Its compares the body's set point temp with the new sensed temp. Then sends a signal to,lets say reduce temp, by dilating( forcing more blood then normal) to surface blood vessels ( thats why people look "red" when they sweat), this signals the sweat gland ( the apocrine & eccrine sudoriferous glands) to turn on and flood the skin surface with a mix of salt,oil and water. the high body temp causes the water to change into a vapor, the salt helps with the change from ligued to vapor and the oil helps keep the skin surface soft and "breathable". When the temp returns to around normal for that human, the hypothalamus re-sets the body's temp. point so it can remember it. So the answer would be, NO, you dont sweat while you swim, but you could start sweating when you get out if your still above what your hypothalamus says you should be.You also have to factor in, the water temp,air temp,time of day,age,or for woman your cycle or if you have a problem in the hypothalamus. Long answer for a little sweat. There are even formulas to understand temp thoughout the body's systems.

It is true, the value of the water is less than the harm done by utilizing body heat to melt it to a usable liquid. You need both heat and water to survive, but you will die quicker of exposure than thirst. Where there is snow there is almost always liquid water, water will pool in low lying areas, and the snow above it acts as an insulating blanket keeping it from freezing. Hydrating yourself will help your body function better, and keep you warmer, just don't hydrate at the expense of lowering your body temperature.\nSurvival is often times a simple cost/benefit analysis, making well thought out decisions combined with a bit of luck can save your life.

It depends on how much water you drank during the course of the day. The healthiest numbers as doctors say is 4-6 for well hydrated people but of course everyones water needs are different. Like If you do sports like football or baseball you need a lot of water but if you do swimming you don't because the water is all around you (even though you don't drink it because of chlorine and other chemicals).

Yup, it's A.  The air is saturated with water, so the sweat on your body doesn't have the chance to evaporate to cool you.

The skin on your palms, fingers, soles of your feet, and toes is thicker, so when it absorbs water, the surface of them buckles.  You will find that other parts of your body will wrinkle up as well, usually around the hands and feet.

You can shower, go outside in the rain, etc. You can do anything you want unless you feel like you may lose a contact, like while swimming. As far as eye health, showering has no effect one way or the other.

That is sweet of you to think that.  But, unfortunately, we do sweat.  We are just better at hiding it;)

Your skin gets water logged...too much water and it starts to swell and bloat and wrinkle. Can you imagine what a drowning victim looks like?  Ewwwwww

our body is composed of 90% water

Because water increases your body's electrical conductivity.

Don't cover your body if you will be runnimg. the plastic makes your body sweat, and you lose water from your body. This makes you look less bloated and makes you look good, but if you are running and you have that plastic on, you might lose too much body water and have a problem. not good.

Yes, water is very good for you.  http://www.watercure.com/

Ok obviously this is for a class - so why don't you consult your text book.  The answer will be in there.  Think about it logically too - your skin, in an of itself is a natual barrier.  It is made of tightly packed cells that are keratinized to prevent too much water getting in.  Get the drift...??

I'm not quite sure what you are asking here.\nHowever I can tell you that in order for us to remain whole our blood exerts a pressure of 1 atmosphere on our skin to balance that exerted on us by the air around us.
