activation of cold-sensitive oropharyngeal receptors results in inhibition of vasopressin secretion. Antidiuretic hormone, also known as vasopressin, is a nine amino acid peptide secreted from the posterior pituitary. Injection of small amounts of vasopressin into a person or animal results in antidiuresis or decreased formation of urine, and the hormone was named for this effect. \n\nBasically, coldness activate receptors in your throat that inhibit vasopressin, a hormone that makes your thirsty. This is the reason that women are allowed to eat ice chips during childbirth and not drink water, in case they have to do surgery, the patient will be less likely to bleed if she is dehydrated.

Warm water increases blood flow, and if you prefer cold showers the cold water is stimulating. Also the smell of the soap no matter how light is somewhat therapeutic. There's also the feeling of washing away problems,stress, anger, and all negative things down the drain.

Because in the summer, we lose a lot of sweat yes? =] so, this sweat has to be replaced with water from the body, meaning why we drink more in the summer, BUT, in the winter, we hardly sweat, meaning a build up of water, and bingo, out it comes, its all homeostasis, blood and body temperatures =], Basically, the water in our body cant escape  through the sweat glands, well, cus its winter, meaning it just builds up and puts everything out of balance. So we pee more. In the summer we dont pee asmuch cus water is lost through sweat.

Because the water conucts the heat away from your body very well and thus lowers your body temperature

actually it will, but it needs to be over time.  This is only because your body will burn calories bringing the cold water up to body temp.  It'll be slow, and you'd only lose around 10 lbs or so a year by drinking a few cups a day.

it's usually because your body is just not awake. drinking water as soon as you get up is actually good. it rehydrates you after not drinking anything all night and the fluid also wakes up your brain.

immersion in hot water tends to dilate your blood vessels, as the body tries to send more blood to your outer surfaces in an attempt to absorb some free heat, hence the reddening of the body in warm water\n\nIn cold temperatures, the vessels will constrict as the blood is sent to the inner core to keep you warm.

I was told by a Shaman healer that drinking water at room temperature is best, as well as warm or hot, because it makes its way though the path of the kidneys beeter at room temp.

According to Prevention magazine (German doctors performed a study a while ago, statistics are shown on the first link), water does in fact boost your metabolism. Heck, eating in general boosts your metabolism--some say spicy food revs it up even more. The benefit of water is it's the great zero calories, and I know it helps the function of organs such as the liver and heart. "Drinking water can help you burn fat, beat a fever, improve your complexion, relieve constipation, build muscle, drain a stuffy nose, fight a stomachache, and improve your mood." <msn.com> But does it boost it much as eating soild, healthy food? I would assume it does but as much, but water is important, and with the other benefits, you might as well do it.

Heat = mass x specific heat of material x change of temperature.\nSpecific heat of water is 1. So the amount of heat needed to be added is the mass of the water x the amount of change needed to get to boiling. So cold water does not boil faster. \n\nsalt will cause it to take longer. \n\nPeople think that tea tastes betterr if you start with cold water, which holds more oxygen. As you heat the water, the oxygen comes out. This may look like boiling.

Water is consumed in virtually every metabolic and chemical process your body engages in. Drinking water will fuel those processes and give you more energy. When you excercise (which of course you are, if you wish to lose weight), you comsume vast amounts of water, usually 2-3 times as much as you sweat out, and you sweat more than you think.\n\nThe process of "digesting" water is catabolic, meaning it consumes calories, so drinking water between meals will keep you from binge-eating later and it will burn a small ammount of calories to boot.\n\nWater is the most pure liquid you can drink, the benefits of water go on and on. Everyone should drink several glasses worth every day.

Research recently showed that hoenstly, just drink when you are thirsty. Your body knows what is good for you. Plus, alot of foods contain water as well, so you get it that way as well. \n\nJust make sure to drink water when thirsty instead of soda or tea.

I also heard that drinking cold water speeds up your matabolism, 'cos your body has to work harder to make the water a suitbale temperature for your body to work on

Contrary to what is believed, alcohol may make you feel warmer but it actually lowers the temperature of the body. When alcohol enters the blood, it causes the blood vessels to widen.  More blood flows to the skin's surface.  The drinker's body temperature drops as the increased blood flow to the surface allows body heat to escape.  People who drink alcohol in cold weather to get warm actually accomplish the opposite.\n\nThough carbohydrates are known to be the best source of heat and energy, all what you eat are actually contributing in producing your body heat. So eat a well balanced diet and wear sufficient clothing to combat coldness while you go out. Instead of bringing a flask of scotch on route why not bring a flask of hot drinks instead?☺

What I have always heard is that if you have been working outside alot, and you are hot, that you shouldn't drink really cold water because it can actually mess with your heart.  The cold water becomes a complete "shock" to the heart, and could do some bad for you.
