Think about all the surfaces, items, clothing, etc, that you touch within a two hour period. If you really think about it, it is kind of gross! Toilets, computers, sinks, doors, doorknobs, stair railings, grocery carts, car handles, phones; and how many of these items have been touched by other people, some of whom may have not washed their hands.
The Center for Disease Control says hand washing is the best way to prevent the spread of microorganisms and infection. This is very important with flu season quickly approaching. The CDC says there are millions of microbes on our hands. Some are harmless, but some can cause illness. Hand washing with soap and water can greatly reduce the spread of germs and bacteria.
The mechanical action of scrubbing loosens the dirt and microbes on our hands, the soap picks it up and binds to the microbes, and then the water rinses it away. Since it is the friction that loosens the dirt, the CDC recommends washing hands for at least 15-20 seconds. If you sing the "Happy Birthday" song, this should cover the amount of time. Does it make a difference what type of soap is used?
The CDC says no. Anti-bacterial or just plain soap, either are good since again it is the friction that is most important. A good tip is to make sure the water temperature is just right, so you can feel comfortable enough to last the 15-20 seconds. Also, if the water is too hot, it can cause your skin to crack or chap, witch leaves room for microbes to enter and cause infection.
Hand sanitizers are also good when soap and water are not available, but make sure to also rub them in, and it should take about 15-20 seconds for your hands to dry.
According to a study on U.S. Navy recruits conducted by Naval Health Research Center washing hands five times a day at least, decreases respiratory illnesses with 45% compared with the year before.
