Why is hand washing so important?

Regularly washing your hands is an important measure for preventing the spread of germs which cause diseases. In most situations, washing your hands with soap and water according to the correct technique, is enough to leave them hygienically clean. However, many people do not wash their hands properly, even if they do use soap and water. It’s important to be familiar with the correct technique so you know how to remove germs effectively each time you wash.

Correct hand washing technique with soap and water

To wash your hands correctly:

  • Before washing hands, remove rings as well as jewellery like bangles you wear on your wrists. Plain rings can be left on, but you should remove all other jewelry, including your wristwatch;
  • Ensure any cuts on your hands or wrists are covered with a waterproof dressing like a plaster (band-aid);
  • Wet your hands thoroughly with water. Either hot or cold water can be used as evidence suggests that they are equally effective for removing germs from the hands;
  • Apply liquid or bar soap to your hands. Use enough soap so that it creates a thick lather over your hands when you rub them together. If using an alcohol based wash instead of soap and water, you’ll need a palmful to wash your hands properly;
  • Rub your hands together to lather the soap. While lathering move your hands away from the running water to ensure the soap is not washed away before it has time to wash away the germs on your hands. This is important as the soapy lather works to suspend dirt and germs so they can be easily washed away. Lather the back and front of your hands, your wrists and your fingernails, ensuring you don’t miss any spots. Commonly missed spots include finger tips, between fingers, thumbs and wrists;
  • Wash all parts of your hands thoroughly for 15-20 seconds;
  • Rinse your hands thoroughly under running water so the germs wash away. Do not use a bowl of stagnant water for rinsing. Keep your hands down to ensure that the contaminated rinse water drains down the sink and does not run up your wrists and elbows;
  • If the tap needs to be turned off manually, cover your hand with a disposable paper towel to turn off the tap. This helps prevent your hands from being re-contaminated with germs on the tap.

It is also important to thoroughly dry your hands after each wash, as wet hands are more likely to pick up germs from the environment. The best way to dry your hands is to:

  • Use a disposable paper towel;
  • Pat your hands dry, don’t rub them. Rubbing your hands can cause skin damage;
  • Do not use a multiple use towel as the towel may harbor germs which can re-contaminate your hands;
  • Hot air dryers which are commonly found in public toilets may also be used to dry your hands. However, they are not recommended if you work in healthcare settings such as a hospital, unless their design has been proven to prevent the spread of germs.

The hand washing procedure should take 40-60 seconds.

Washing with antimicrobial soap

If you are a nurse, doctor or other healthcare professionals, you may need to wash your hands with antimicrobial soap before touching a patient. To wash with antimicrobial soap you should follow the above steps, but use a soap with antimicrobial activity instead of normal soap. You will need to lather and wash your hands with the anti-microbial soap for 60 seconds (not 15-20 seconds as per the standard procedure).

Other tips for keeping hands hygienic

Other tips which may help ensure your hands are hygienic include:

  • Keep your finger nails short and clean. Artificial or long fingernails make hand hygiene difficult because dirt and germs get caught under the fingernails. Ideally nails should be trimmed to <0.5cm long so that soap can get under the nails during hand washing;5
  • If you use sponges or clothes for washing your hands they must be washed frequently with bleach. Clothes and sponges provide moist surfaces, ideal for the growth of micro-organisms.
