Whether it’s that compulsive hand-sanitizing colleague or a packet of miracle powder at the drugstore, advice on how to fend off flus and colds during the dark months is everywhere. While some of it works, much of it is a total waste of time.

See which of these you subscribe to and tally up your own score—our experts say if you hit 35 or more, you’re pretty well protected; if less, it’s time to stock up on oranges.
