Washing our hands is an important practice to remove dirt, germs, and harmful substances. It involves using soap and water to clean the surfaces of our hands thoroughly. This process helps prevent the spread of illnesses, especially during cold and flu season. To wash hands effectively, wet them with clean water, apply soap, and scrub for at least 20 seconds. Make sure to clean between fingers, under nails, and around wrists. Rinse well and dry with a clean towel or air dryer. Regular handwashing is essential for maintaining good hygiene and health.
