How long does it take to actually wash your hands

First of all, Jenny applied a special gel to her hands, which contains very small particles, approximately corresponding to the size of bacteria. Another interesting feature of this gel is that these particles can glow when exposed to ultraviolet light. Thus, you can fairly accurately determine how much hand washing was able to clean the skin. The lighter the hands in the photo, the dirtier they are, and the darker they are, the cleaner.

Easy rinsing

Many people, especially when in a hurry, find it sufficient to simply rinse their hands. As you can see in this photo, this procedure has little effect on bacteria. A slight darkening is observed only on the tips of the fingers, and the rest of the hand remained practically unchanged.

Six seconds

According to omniscient statistics, most people spend no more than six seconds washing their hands. Are you surprised? However, even this short amount of time can provide good results, especially if you are using soap. The photo shows that the experimenter's skin has acquired a much darker shade, which means it has become cleaner.

Fifteen seconds

Research by Carl P. Borchgrevink, JaeMin Cha, SeungHyun Kim. Hand Washing Practices in a College Town Environment. The University of Michigan found that only 5% of people wash their hands for 15 seconds or more. However, this is exactly how long it takes to remove almost all bacteria from the surface of your hands. In the photo, we see a hand on which only minor specks of gel remain, which indicates its purity.

As you can see, getting your hands wet is not enough to maintain good hygiene. Spend a little more time on this procedure, be sure to use soap, and you will get a really good result.
