The Science of Handwashing: Effective Techniques for Germ Elimination

Frequent hand washing is an efficient way of preventing the spread of germs and disease. Of course, it must be done properly. Cutting corners will diminish its effectiveness.

Misconceptions

• Simply soaping up and running your hands under water for a few seconds does not constitute proper hand washing. It's a specific process that, while simple, must be followed in detail to promote good health. In addition, antibacterial soap does not provide any advantage over regular soap, according to MayoClinic.com

Hum a Tune

• Wet your hands with running water, and then apply soap. Rub your hands together for 20 seconds (humming "Happy Birthday" twice through will help you if you prefer not to count). After rinsing thoroughly, dry your hands with an air dryer or towel. If you can, dry with a disposable towel and then use it to turn off the faucet.

Alternative

• In lieu of running water and soap, hand sanitizer is a viable option as long as it has at least 60 percent alcohol, according to the Centers for Disease Control and Prevention. Use the recommended amount, and rub over your hands until completely dry.
