How many times a day does a person need to do hand washing?

Answer 1

A person does not "need" to wash their hands on a daily basis, but rather "should" wash their hands whenever circumstances dictate.

These instances include:

• when your hands are dirty
• before eating or touching food (like if you're helping cook or bake, for example)
• after using the bathroom
• after blowing your nose or coughing
• after touching pets or other animals
• after playing outside
• before and after visiting a sick relative or friend

So the conclusion is that, you need to wash your hands a lot.

Probably every three to four hours or so.
