BANG FOR THE BITE
If 10,000 Biters use cold water instead of waiting for hot, in a year we'll save enough water to fill 21,600 bathroom sinks to the brim.
COCKTAIL FACT
The American Society for Microbiology recently found that 1/3 of men didn't wash their hands after using the bathroom.

Do energy and water bills drain your resources?
The Bite
Put a plug in it. Consider using cold water instead of hot to wash your hands, since the cold, hard truth is that cold's usually just as effective.The Benefits
- Saving energy. Every 10-degree drop in H2O temperature saves you 3%-5% on water heating costs.
- Saving water. Most faucets spit out 2 gal per min while you're waiting for the water to warm up.
- Clean hands. With hand washing, the friction and the soap are what really get your hands clean. As far as water temp goes, you'd have to rinse your paws in boiling water to actually kill germs.
Personally Speaking
Most of us usually washed with cold even before we thought about the eco-friendly factor. At last, patience isn't a virtue.Wanna Try?
- The cold-water knob's usually the one on the right.

Contortionist Cleaning
Whether washing your hands in a public bathroom actually gets rid of germs or attaches more to you probably depends on the place, but for my part, I don't really see the point in scrubbing up, only to then put my freshly cleaned mitts on a faucet and door handle that strangers-who-have-touched-god-knows-what have wielded. So if I need to wash hands before, say, eating out at a restaurant, my choices are to a) use a liquid hand-sanitizer or b) wash my hands in the bathroom, then use my forearm and/or elbow to turn on the faucet and turn the door handle on my way out.
I recommend that latter, if you can bust the moves, since it means one less thing to carry around and one less plastic bottle to recycle. If you use a paper towel to dry, you can even use it as a kind of mitten until you've opened the door, then hold the door with your body, crumple the mitten, and shoot for the trash can. It's fun. Try it, and see.

I pride myself on doing all the right things to reduce my energy and environmental footprints, but I'd never thought about washing with cold water. Great tip!
Washing your hands with cold or hot water does not dry out your skin. As you age your sking produces less of the natural oil that helps your skin keep its moisture. Dry indoor air and excessive washing in HOT water causes your skin to become dry.
Two other hot/cold water related tips:
If you own your own place, you can install an electric tankless water heater under your bathroom sink (or other place far from your central water heater). As soon as you turn on the hot water, it turns on and heats the water, so you don't waste all the cold water in the pipe. Google "tankless electric water heater" to see some options. The cheap ones ($150 or less) are adequate.
Another hot water waster is laundry. On your washer, just choose colder water than you'd normally use, e.g. warm for whites and cold for everything else. It saves an enormous amount of energy, and try to tell the difference in how clean your clothes are. If there's a load you absolutely have to use hot water on, then use hot for that one load, and cool things down for everything else.
I have a small "Point of Use" hot water heater ready to install under my bathroom sink. Washing my hands in cold is one thing but washing my face in cold water before bed is just TOO excillerating. I had purchased an Instant tankless heater but returned it because it would have been a major rewiring project. Also liquid hand sanitizers should not be used regularly or they can reduce your natural bacteria fighting ability.(or so I've read).
Another way to save water is to place a large bowl or basin in your sink while washing your hands, and then using the leftovers to water your plants.
Don't worry about the soap - soapy water can actually be beneficial to plants, as the soap breaks up the surface tension of the water and allows it to bind more closely to the soil, so that less water runs through the pot and more is available in the soil when the plant needs it.
I already wash my hands with cold water unless it's really cold. Both the weather and the water. We have a deep water well, and in the deep of winter our cold water is really, really cold. We turn the hot water heater on when we get up and then turn it off about mid-day. That has significantly cut down on our electric bill. I saw a post about tankless water heaters. Funny thing about them. Our water pressure isn't too hot. Our shower is upstairs and when one of us took a shower the water heater would turn off and talk about a cold shower! We solved that by running the bathroom sink while taking a shower. When the water heater broke down and would cost over a hundred dollars to have repaired, we ended up buying an small, electric water heater. After the electric company paid us a rebate, the thing was free. An added plus is that my husband is an electrician--free installation.
I gotta say I disagree with both of your points on this. Most people do not wash their hands long enough to kill many bacteria. If you're washing your hands in cold water, you're likely to wash them for an even shorter amount of time. Also, warm water cuts grease better than cold water.
Also, antibacterial hand-sanitizers are a big environmental no-no. They are causing all kinds of problems in our waterways and helping to create resistant strains of bacteria. if you don't want to tough the door knob after washing in a public place, do the towel or elbow thing. But really, we're all a little bit too germ-phobic these days anyway. And ironically, if we keep using these anti-bacterial cleaners, we might have a reason to be.
My parents turned off the hot water supply pipe to the powder room...the water never got hot in under three minutes there anyway, so guests were just using cold water from the hot water line---which forced hot water from the tank into the long pipe through the house--where it cooled off before it was summoned again. No one ever said anything. The family bathroom--where faces are washed, had hot water--we were told to use only cold for washing our hands, though--and all this was in the 70s.
I don't use warm water for the germ-killing effect because I already knew it is not hot enough. But I believe cold water will have a bad long-term effect on the joints. It will suck to get arthritis in old age because of cold water.
At home I don't have the patience to wait for warm water but in public places the good thing is that the use keeps it warm.
speaking of washing hands,cleanliness, etc. here is what I do mostly at the grocery story, but also at restaurants and so on. Wash your hands in nice soapy (cold) water; dry them on ONE paper towel, making sure it gets some wet-soapy on it; use the towel to open the door handle on the way out of thebathroom - can you imagine how dirty it is? then use it to wipe well the handle of your grocery cart - also probably filthy dirty - keep the towel to use it as you see fit as you shop, then throw it away at checkout. A cleaner way to shop!
I am more than willing to wash in cold water, except when it means freezing my butt off or my kids butt off. Cold water in cold weather is not pleasant and can be painful in my situation.
I didn't use hand sanitizers when they first came out. That's because I have a touch of psoriasis, and those hand sanitizers, being mostly isopropyl (rubbing) alcohol, made my already-dry skin even drier. But now, there are hand sanitizers with aloe. Those are terrific, and they're the ones I use.
Not a bad suggestion, but would be great if Ideal Bite could amend the tip with a recommendation from some objective source for the hand washing time that you need to do to get rid of germs. I think it's something like 20-30 seconds (sing Happy birthday to yourself, and apparently that does the trick) and is it okay to not use soap? is it the time plus the vigorous smooshing of your hands together? but i did go EWWWW when I read the factoid about men not washing their hands after using the little boys room. I sent it to my husband, not that he forgets to wash, but just to remind him anyway. That's a career no-no...
Good post, Recently i bought hands free soap dispenser from BrookStone store at couponalbum.com(http://www.couponalbum.com), on great discounted prices..
