Lather your hands by rubbing them together with the soap. Make sure to lather the backs of your hands, between your fingers, and under your nails.

Rinse your hands well under clean, running water.
Dry your hands using a clean towel or air dry them.

What Should I Do if My Hands are Dry or Cracked?

Dry or cracked hands can be more susceptible to infections. To prevent this, use moisturizing soap and apply a moisturizer after washing your hands. Also, avoid using hot water, which can dry out your skin. If your hands are severely cracked or dry, consult a healthcare professional.

How Can I Teach Children About Hand Hygiene?

Teaching children about hand hygiene is essential. Make it a fun activity by singing a song while washing hands, using colorful posters to illustrate the steps, or rewarding them with stickers for remembering to wash their hands. Lead by example and make hand hygiene a regular part of your family's routine.
