It's time to drink up!
No, I don't mean alcohol, even though it does seem to be the season for that sort of thing.
It's also the season for a friendly reminder about the importance of staying hydrated during winter activities.
Not surprisingly, it's much easier to keep proper hydration in mind when it's 90 degrees and we're sweating up a storm while playing tennis or going for a run than when we're skiing or snowshoeing in the subfreezing cold.
But body fluids can be lost during exercise in the cold just as easily as in the heat. You know those vaporous exhalations that are a trademark of winter breathing? That's water being lost. Cold weather also makes us urinate more frequently, promoting dehydration.
It's always a good idea to drink plenty of fluids, preferably water, before and during any vigorous cold-weather activity. Remember, if you wait until you feel thirsty to start drinking, it's too late — you're already dehydrated.
Cheers, and have a merry Christmas.
