7 Things You Don't Know About Colds
You know the germiest places in every room
and could write a tutorial on hand washing, but you'll still be surprised by the sneaky ways colds affect us.
You can drink milk.
You've been told that drinking milk doesn't cause a sick person to make more mucous
and that the phlegmy feeling you may notice is the liquid temporarily coating your irritated throat. Still, you figure there's no harm in easing up on the dairy until your nose has stopped running—or until cold season is over. This strategy really
won't help, says Collins, and it could backfire. She explains that the vitamin D in milk can also boost your energy while your body is fighting off pathogens, and the liquid will keep your tissues hydrated. What's more, vitamin D spurs cell growth and helps keep your immune system working optimally
—potentially preventing you from getting sick in the first place. Those who are still firmly anti-milk (for whatever reason) can get their vitamin D from fish like swordfish, salmon and tuna, or from fortified orange juice or cereal.
