Welcome back everyone! Did you miss us? Well, we certainly miss all of you guys! Anyway, today we're gonna talk about washing hand with only water vs washing hands using water and soap.
according to dailymail.co.uk, there is a test of different hand-washing techniques.
To find out they used a special UV camera to test different hand-washing techniques - from the typical 'rinse and shake' to the 30 seconds recommended by a leading authority on disease control.
First, they rub on a gel known as Glo Germ, which simulates how bacteria cling to your skin. The gel, which is clear but 'glows' under UV light, is used as a visual aid in hygiene training - it's been used for training nurses who are going to be working with ebola patients, for example.
The gel contains particles the same size as bacteria, so any that's left behind (ie, that shows up white in the UV light) gives you an immediate idea of how good your hand-washing technique is. In other words, the whiter the hands in these pictures, the dirtier they are - and the darker they are, the cleaner.
The results may make you think twice next time you're at the bathroom sink...
The whiter the hand, the more bugs left after washing.

covered with germs- shown by white glow. The whiter the hand, the more bugs left after washing
Picture 2 - Rinse and shake
there's no soap or towel, or we're in a rush, so we make do with the merest of rinses under a running tap and a quick shake to get our hands dry.
Rinse and shake doesn't achieve much. after running my hands under the tap for three seconds, my hands show up a glowing white under the camera - suggesting lots of bacteria will have been left there.
Picture 3 - six second wash without soap
six seconds is the average length of time people spend washing their hands, according to research.But this is not long enough to effectively remove bacteria.
Washing my hands for slightly longer has reduced the white areas - the amount of 'bacteria' - on my hands compared with rinse and shake (especially on my palms, not shown), but there is still a high concentration on the backs, around my wedding ring, under my fingernails and in my cuticles.
Picture 4 - six second wash with soap
soap doesnt kill bacteria, it gets rid of them. Proof soap helps- but those fingers are still filthy. when you wash your hands, you should scrub the tips of your fingers against your palms to clean under the nails
Picture 5 - fifteen seconds with soap
the normal time needed to wash hands. As you can see from the picture, there are far fewer white areas than with the typical six-second wash.
The only white areas are the crescents around my cuticles, a patch on the side of my thumb and a streak on the top of my little finger. 'You should wash for 15 seconds because you need that time to clean all the little bits of your hands,' says Dr Ackerley
Picture 6 - thirty seconds with soap
careful technique or washing for much longer you get rid of the remaining few bacteria, but it's getting rid of the majority that matters.
There is a visible difference- there are even fewer white areas. the crescents of bacteria around my cuticles in the 15-second picture have all but gone-though i'm amazed to see there is still a trace.
so, you already know what's the different if you wash your hands just with water and water&soap, right? washing your hands with soap and water is the most effective for washing hands. it get rids more germs on your hands. so which one do you choose? do you still want to wash your hands with water?
p.s be aware, wash with care
