Water temperature when washing your hands does not matter

• REGULATION OF A new study*: Washing your hands with cold water for ten seconds led to a decrease in the germ concentration of 1.93 tens of tens (two tens of ten: minus 99 percent). Statistically, there was no statistical difference for the use of water with 40 degrees Celsius (minus 2.01 powers).

• It was similar to 20 seconds of the washing process (cold water minus 2.23 dozens of potentials; hot water minus 2.39 ten potential). However, the stronger effect of the time that washing longer was already statistically significant compared to just ten seconds.

A minute helps best
However, all experimental arrangements were statistically inferior at a minute washing with soap. The number of germs on the fingers can be reduced by 2.68 powers.

The hand flushing for ten or 20 seconds with cold (…) or hot water ‘was considerably worse than the only reference process of the hands of the hands with Sapo Kalinus (potassium soap; comment), but there were no significant differences between the use of cold or hot water in pairs comparison for both times.

Expensive influences the germination reduction
However, the duration seems to have an impact on the reduction of the germ, because the differences between the hand detention times were significant for both temperatures, “the scientists said.
