Wash Your Hands Long Enough
The Apple Watch helps you keep your hands virus-free with a new handwashing feature that Apple added to watchOS last year. The handwashing feature automatically detects when you begin washing your hands and starts a 20-second countdown timer. This 20 seconds of scrubbing with soap and water helps ensure your hands are sanitized and free from the coronavirus that causes COVID-19. You can turn on the handwashing option in the settings app on the Apple Watch.
