Whenever you’re sick and you sneeze, you’ve probably got lots of adults telling you to use hand sanitizer. You’re always told it kills microbes. it even says so on the bottle. These are too small to be seen. In fact, for a long time, doctors and scientists didn’t even know that microorganisms existed. They tried many things to stop sickness from spreading. But without knowing about microorganisms.
Using hand sanitizers does not create super germs it’s a bit of a misconception, a lot of times people confuse hand sanitizers with antibiotics.
Antibiotics
What they do is target very specific proteins in a cell and they kill the bacteria slowly so the bacteria can mutate and can generate resistance. Alcohol works in a different way, it works to physically disrupt bacteria it not only disrupts the membrane and literally leads to bursting of the bacterial cell but it also denatures all the proteins within the cell so these are physical mechanisms and they happen fast within a matter of seconds so there’s no chance for the bacteria to mutate or develop resistance to it.
The Microscope
The very first microscope was invented in the 1600s by someone names Antonie van Leeuwenhoek. Now having a microscope meant it was the first time that we could see things as small as bacteria. The very first microscope was invented. It’s so easy for us to carry around these microscopic bacteria and viruses all over our hands without even knowing it. Scientists realize if we could discover ways to kill or remove some of these bacteria then we could stop sickness from spreading.
Hand Sanitizer – Hand sanitizer is one way that we can kill bacteria.
How does it work?
Using a lot of hand sanitizers can leave your hands feeling a dry. That’s because it mostly made of a substance called alcohol.
Alcohol Properties
Alcohol is a substance with many interesting properties. One of these properties is that alcohol dries up the oils on your skin, which is what makes your hands feel dry. But while it’s doing that, it’s also drying up the bacteria on your skin. When these get dried out, their outer layer gets broken open instantly, killing it. Now keep in mind, if your hands have dirt on them, using it will not get the dirt off. For that you still need to wash with soap and water.
Conclusion
Regular cleaning agents (liquids, powders, sprays or granules_ remove dirt, dust, debris, and odors from surfaces. This is an important first step in improving the health of any environment. It does not prevent the spread of disease.
Hand sanitizer kills germs because it’s mostly made of alcohol. And alcohol can break open the outer layer like bacteria or viruses. Doctors recommend using it whenever you don’t have soap and water to wash your hands, so you can keep from spreading it.
There is a significant difference between cleaning sanitizing and disinfecting. For example, cleaning by itself is relatively ineffective at preventing the spread. However, disinfectants and sanitizers have issues with effectiveness for dust and soil, underscoring the importance of cleaning before sanitizing or disinfecting.
