When teaching personal hygiene it's useful to explain what germs and bacteria are, and how they affect a person's health. Teach proper hand washing, dental care and bathing techniques.
When teaching hygiene, exercises that show how the spread of germs happens are helpful. Covering a person’s hand with chalk and having them shake hands with another person shows how easily and quickly germs are spread from one person to another.
When teaching hand washing, demonstrate how to thoroughly wet the hands and lather with soap. Proper lathering should take about 20 seconds, and some people hum a short song such as "Happy Birthday" to help remember how long to lather the hands.
Teaching when it is necessary to wash the hands is also important. Make a list that includes appropriate times to wash hands, like before preparing food, after using the bathroom, and after sneezing or coughing.
Dental hygiene is an important topic, which includes brushing teeth and flossing. Demonstrations of proper brushing and flossing techniques are crucial to proper teaching. Dental dye tablets can show residual plaque and help improve brushing technique.
Demonstrations of how to use shampoo, deodorant and body wash are helpful to people lacking personal hygiene skills. Having the person pick out their own bath products can make the process more fun.
