Hand Washing: the original infection defense

Hand Washing — the original infection defense. Hand hygiene remains one of the most effective ways to reduce respiratory and gastrointestinal infections. Soap and water physically remove pathogens, while the time spent scrubbing matters more than water temperature. Scrubbing for 20 seconds, including under nails and between fingers, is the standard recommendation. It fits real life, which is exactly why it survives long after motivation fades. Researchers point to shifts in gene expression, circulation and waste clearance. Pair it with something you genuinely enjoy and adherence takes care of itself. For most adults, wash hands after returning home, before eating and after coughing or sneezing. Guard the habit the way you would guard a real appointment.
