What’s the best way” soap or hand sanitizers?
Sanitizers are the easy and modern way to washing hands that most people use now. As per recommendations the best way to eliminate germs and the best practice to follow is washing hands with soap and water. However in cases when water and soap are unavailable you can use an alcohol-based hand sanitizer which will help kill the germs.
In order to understand this, it is also essential to know how handwashing works with soap and water and with a hand sanitizer. The primary purpose of a hand soap is to remove the bacteria and germs and not kill it, whereas a sanitizer kills the infectious germs. When washing your hands with soap and water the germs get trapped in the natural oils of the skin and get washed away with water. A sanitizer, on the other hand, kills the bacteria by making it ineffective.
In any case, if you have access to water and soap, it is best to follow the traditional means of handwashing. Alcohol-based hand sanitizers are acceptable in cases when water and soap aren’t available as they are for on the go cleaning.
Will ordinary soap do the job or do you need medicated soap?
Washing your hands with soap and water is the most commonly used practice. Using a soap is much more beneficial than just washing hands with water. It is always recommended to use a liquid soap instead of a bar soap because bar soaps, when used by many people tend to get infected or its impact wades off. Some people, however, tend to have skin irritation caused by soap. Such people may need to use soaps that have a different pH and are rather mild.
All soaps are equally effective in killing germs, provided proper and effective handwashing techniques are followed. There is no need to use a specific anti-bacterial or medical soap for this purpose.
There is a lot of concern about hand sanitizers and their real function. What is the truth about them?
Washing hands using soap and water is the best way to reduce the number of microbes in most situations. When the hands are visibly dirty or greasy washing hands with soaps is highly recommended. In case of non-availability of soap and water, for example, while traveling the hand sanitizers will be of some help. However, hand sanitizers cannot remove all microbes on the hands effectively. Hand sanitizers are not recommended for infants and children as they tend to put their hands into their mouths and it can lead to alcohol poisoning. Sanitizers cannot remove harmful chemical contaminants from hands whereas washing hands with soap and water are the best thing to do in such situations.
Can they also kill the good bacteria and harm skin?
Hand sanitizers are widely used today by children and adults equally, in everyday practice. People have sanitizers in their cars, bags, office desks etc. and use it to clean not just their hands but also areas around them.
From our skin to the internal structures within the body, there are bacteria everywhere. The immediate thought upon hearing ‘bacteria’ is infection-causing agents. What most people fail to realize is that there are two types of bacteria; good bacteria and bad bacteria. The good bacteria are also known as probiotics and protect the body from diseases and allow the body to stay immune.
It is true that hand sanitizers kill not only the bad but also the good bacteria which live on the skin acting as the first line of defense against germs. Presence of these good bacteria is important as they prevent and protect the skin from major injury. The absence of these bacteria on the skin causes skin inflammation.
Sanitizer does not necessarily harm the skin, although alcohol-based sanitizers may harm cause skin irritation in those who have sensitive skin.

Washing hands is a family activity that both parents and children should always practice. Unfortunately some adults overlook the importance of hand washing and set a wrong example to children. Many a times children do not listen to parents when they are asked to clean their hands before eating, after using the toilet or when they come home after playing. It is an instruction worth repeating to children as it is a simple and the best way to keep away infection. So it is the responsibility of adults to reiterate the importance of hand washing to children.
