Wash Your Hands Properly: 20 Seconds with Soap

The Problem

You quick-rinse your hands and call it done. You get sick 3-4 times per year.

The Hack

Wet hands, apply soap, scrub all surfaces (palms, backs, between fingers, under nails) for 20 seconds (sing Happy Birthday twice). Rinse and dry with clean towel.

Why It Works

Brief rinsing removes fewer than 50% of germs. Soap dissolves the lipid membrane of viruses and bacteria, and 20 seconds of friction physically removes pathogens. This reduces illness by 50-60%.

Pro Tips

• 20 seconds = sing Happy Birthday twice
• Soap type doesn't matter — antibacterial isn't more effective
• Key moments: before eating, after bathroom, after public spaces
• Hand sanitizer (60%+ alcohol) when soap isn't available
