Wash Your Hands at Transition Points, Not Just When They Look Dirty

Your hands pick up far more than you can see. The most effective handwashing habit isn't about visible dirt — it's about transition points: coming home, before eating, after public transport, after touching shared surfaces, before touching your face. These are the moments when germs actually move from the world to your body. You don't need to be obsessive about it. Just build the reflex at key transitions, and you'll cut down on colds, stomach bugs, and random infections significantly.
