Even if our hands look clean, they can still be covered with millions of germs. Germs are microbes that are invisible to the naked eye. Germs on unwashed hands cause illnesses, for example pneumonia and diarrhoeal diseases. Washing hands with soap is one of the most important ways to keep ourselves healthy and stop these germs from spreading from one person to another.
When to wash hands
- Before eating food
- Before, during, and after preparing food (especially after handling raw meat)
- Before and after caring for someone who is sick
- Before and after treating a cut or wound
- After using the toilet
- After cleaning up a baby or child who has soiled himself or herself, or used the toilet
- After touching animals, animal feed or animal waste
- After touching rubbish
- After blowing your nose, coughing or sneezing
Many people wash their hands with water alone. However, this is not enough to remove germs. Using soap breaks down the grease and oils on our hands that carry the most germs.
Problems with soap use
Soap left near hand washing facilities often goes missing. It is too valuable a resource to leave around, yet it needs to be available wherever hand washing takes place, in the home or in public places such as schools. Soap on a rope is often the best option.
However, it is not enough to have soap in the home. We need to wash our hands with soap at important moments to prevent germs spreading (see box above).
A household bar soap can be used on the hands. A special type of soap for washing hands is pleasant but not essential. If soap isn’t available, then ashes or an abrasive agent such as sand can help cleanse hands.
- Think about ways your community could improve local, affordable soap supplies.
How to wash hands
1. Hand washing does not depend on having a tap with running water. Improvisation is the key! A tippy tap, a bowl and jug, and a bore hole are all good options. Running water is best but not essential.
2. The temperature of the water is not important.
3. Wash all hand surfaces: palms, backs, wrists, finger tips and between fingers. The order does not matter.
4. Keep fingernails short so they are easier to keep clean.
5. It is important to dry hands properly before touching anything. Use a clean cloth or shake them in the air. Damp hands pick up more germs than dry hands.
6. If water is difficult to come by, wash hands whenever the opportunity arises.
Building low-cost or no cost hand washing stations can help people take the step from simply understanding the importance of hand washing to actually practising hand washing with soap. The Tippy Tap is widely promoted and used for hand washing around the world. It’s simple, cheap, and allows hand washing with only a little water. It is also easily adaptable to suit local situations and preferences.
Other types of hand washing stations are being developed in a number of countries. The design stage is very important.
- Designing a hand washing station must take people’s preferences and practices into account.
- Many tests may be necessary before the best design is found.
- A universal design for a hand washing station may not be possible.
You will need paper and pencils or pens
Ask the children to draw round their hands, one hand with the palm down and one hand with the palm facing up. Once they have an outline, they should remove their hands from the paper and draw on fingernails and any lines and creases they see on their hands.
- Explain how sickness spreads through unseen germs on our hands.
- Ask the children to look closely at their hands.
- Ask them ‘where might the germs be hiding?’
- Ask them to imagine they have put their hands in some soil. Ask them ‘where does the soil stick?’ The answer will be under the fingernails and in the creases of the hands. You could demonstrate this on your own hands with soil, and follow it by washing your own hands with soap so the children can see how it should be done.
On the pictures of their hands, the children should draw where the germs might be hiding. It doesn’t matter how they choose to draw the germs.
Use this activity to help children think about when to wash their hands. Help them understand that their hands need washing when they look dirty and sometimes when they look clean but may have germs on them. Emphasise the importance of washing hands thoroughly with soap to get the germs out of the creases and from under the fingernails.
Ideas for using this article
- Use it like a poster that you can refer to and pass around a group during discussion or training.
- Use the ‘Five fingers – count to five’ when training others.
- Develop the children’s activity. Children can also learn the ‘Five fingers – count to five’.
