cold water

I've been swimming a lot lately and after a workout last week, one of the other ladies was asking me about where I got my bathing suit. I couldn't help but notice her skin. I said, "I'm no doctor, but I think you've broken out in hives." She just laughed and said that it always happens when she swims in cold water. I couldn't believed she was so nonchalant about it, since her body looked like a range of moguls on a Black Diamond ski trail. She said it doesn't hurt and always goes away, so she thought it wasn't a big deal.

When I went home, I couldn't get that image of her hive-covered skin out of my mind, so I decided to do a little Internet research. In the medical world, this condition is called physical urticaria. To see the risks it poses, read more

Seventh Generation, a brand of environmentally safe household products, launched a special effort, called Get Out of Hot Water, to get people to pick up some green habits in the laundry room.
The company is asking people to pledge to switch to cold-water washing – and are offering a free copy of their book, Naturally Clean, a guide to healthy nontoxic cleaning, to those who do (while supplies last). You already know that washing in cold water is good for your sheets, but it also has a significant positive impact on the environment. Using a cool cycle, saves 90 percent of the energy used in machine-washing a load of laundry, effectively lowering your carbon footprint by preventing the release of energy-related greenhouse gases. It also can amount to a savings of about $70 in annual household energy bills. Making the pledge (easy as pie) and registering your name and address will make you eligible for the book. For those of you who were concerned that washing in cold water doesn't kill as many germs, Seventh Generation has a new production line, 2X Concentrated Laundry Liquids, which works overtime in cold water, getting clothes "hot-water clean with cold-water efficiency."

We've all done it, we've bought lettuce with the perfectly good intention of turning it into salad, only instead of making a salad, we throw it in to the back of the fridge and forget about it for a while. We come back a few days later and find that the leaves look a bit sad and wilted. Well, what do you do? Do you toss it out? Nope! You soak it! Place washed lettuce leaves in a bowl (preferably stainless steel) filled with cold water, lemon juice and ice cubes. Soak for an hour in the refrigerator, then drain, dry and enjoy! Oh and let's be realistic here folks, if your lettuce is starting to turn to soggy mush, no amount of lemon juice is going to save it.

Oh how I love science. Or should I make that, oh how I love Japan. How about, oh how I love Japanese scientists... An environmental consulting firm based out of Tsukaba, Japan has come up with an amazing new product called "Hotto! Raisu." The product, which amazingly turns cold water into hot rice, is a non-perishable food pack that could be put to good use during a natural disaster.

So how'd they do it?

By subjecting rice to 4,000 times normal atmospheric pressure, the developers were able to preserve rice for long periods in a soft form that holds moisture. When water is poured over an exothermic agent in the pack, steam warms the rice contained within, and after about 15 minutes, the dish is piping hot.

Right now the product is decently priced, (10,000 yen for 30 packs, or approximately $85 for 30), but I don't know if that's cheap enough to be ideal for natural disaster zones. Either way it's still absolutely awesome.

All these years I have been cooking with cold water because I was under the impression (damn you, 5th grade science teacher) that cold water boiled faster than hot water. I have no idea why I was told that, or why I believed it for that matter but I did. The truth is, cold water does not boil faster than warm water, but that is beside the point.

So should we all be cooking with warm water to speed up the process? Think again. Never cook with or consume water from the hot-water tap. This is because hot water dissolves more lead more quickly than cold water, which means you may be consuming more lead than you should be. Houses built before 1986 are the most likely to have lead parts, however even plumbing legally considered lead-free today may contain up to 8 percent lead. While copper pipes replaced lead ones decades ago, fusing pipes with lead was legal until 1991.

Why does it matter? Well, too much lead in the body can cause serious damage to the brain, kidneys, nervous system and red blood cells (it's especially bad for pregnant women and children). So the EPA recommends that you do not use water taken from the hot tap for cooking or drinking, and especially not for making baby formula. If you need hot water, draw water from the cold tap and heat it on the stove. Anytime a faucet hasn't been used for at least six hours, "flush" all the water that has been sitting in the pipes. This could take anywhere from 5 seconds to 2 minutes. When the water stops getting colder, it is "flushed."
