    Many healthcare workers know that washing hands is important to prevent the spread of infectious disease. 1. During a study conducted by Nicas and Best at Berkley University, they counted the number of times people touched their face with their hands. 2.Whether we are aware of our actions or not, most of us can agree that we touch our face with our hands frequently enough.

Imagine that you are able to record a full day of your actions. Better yet, reflect on what you did when you woke up yesterday morning. Let me give you an idea of my previous morning. I was woken by the alarm clock at 6 am. 3.Then I checked my phone for messages, turned on the TV for my morning news, started making my coffee and finally hit the shower. It wasn’t even 5 minutes from the time I awoke and I already touched different objects. The point of this is to be aware that even in our homes we are exposed to germs in places we don’t realize.

Luckily, the human body has amazing defense against harmful germs. 4.Our white blood cells are like soldiers coming to the rescue. Unfortunately, there are a lot of areas on our face that do not have the protection of skin such as the eyes and mouth. There’s a reason to every wise proverb and our parents annoying us to wash our hands before dinner is not for nothing.

5.If you have children, it is even more important to set the example because children are known to learn from adults. Let’s start a good habit of washing hands.
