Get obsessive at the sink
First, know that it’s not the antibacterial ingredients in liquid soap that help fend off the virus; studies have shown basic bar soap works just as well. And it’s not very hot water, either. Short of boiling temperatures your skin can’t tolerate, research shows that cold, lukewarm and hot water are equals in this fight. What actually helps fend off flu is the physical friction of rubbing your hands together for at least 20 seconds at a time — yeah, that’s a while: One study showed that people typically spend a mere six seconds at it. And you need to wash more often than you may consider reasonable in a day. If you followed the Centers for Disease Control and Prevention guidelines for when to lather up and scrub, you’d be at the sink more than a dozen times a day: before and after preparing food, prior to every meal, after every visit to the toilet, of course, but also in about 10 other instances that include handling any garbage or feeding your pet. Where experts say your technique is likely to otherwise break down: skipping the backs of your hands or not washing under your nails, where a high concentration of microbes is found. If you can’t scrub this intently when, say, you’re getting off a train and rushing to a meeting, use hand sanitizer as a stopgap, but check that it contains the 60 percent alcohol that’s needed to make it effective at fighting flu germs.
Stop touching your face
Yes, you can get the flu if someone coughs on you or, possibly, if you just stand close to someone who’s sick (so says a recent University of Maryland study showing how the tiniest particles of the virus may move through the air, not just through respiratory secretions). But just as often, you catch the flu by your own hand. So guard the entry points and don’t scratch your nose, rub your eyes or absentmindedly chew your nails, and be especially watchful of touching possibly contaminated surfaces … and then touching your nose, mouth or eyes. Germs can live on something like a phone or computer for up to 24 hours (which makes antibacterial wipes for the office a good idea).”
