Water, water everywhere

Why is it so important to drink water when you are sick or exposed to others who may become sick? Water lines our respiratory passages, and our digestive tract. Both of those organ systems are our main defense against germs. If those systems are dry and unhealthy, it’s easier to let germs take hold. Plus, we tend to get dehydrated in winter because the air is drier and we have the heat on. Outdoor winter activities can be just as dehydrating as those in the summer.
