WASHINGTON — In the hot sticky mess that is the Washington summer,
drinking a lot of water is essential. But it’s just as important in the
winter — and especially if you plan on standing outside in the cold.
“During the winter months, people tend to consume less amounts of water than
they would in warmer months,” says Jody Miller, an
exercise physiologist with Women’s Health and Support Services in Potomac,
Maryland.
She says she sees it all the time in her practice, and finds that many people
think if they are not sweating, they don’t have to worry about dehydration.
But the fact of the matter is, we lose moisture in our body with each breath –
– especially when we are breathing frigid, dry air.
“We notice that in our skin, when we feel hungry when we are just really
thirsty,” says Miller, adding that for those who exercise regularly, “it can
impact our workouts in just so many ways.”
It’s estimated that human bodies are up to 60 percent water, which is a vital
nutrient for every single cell. It also lubricates joints, regulates the
internal body temperature, protects the brain and spine, and helps flush out
waste.
Symptoms of mild
dehydration include a dry, sticky mouth, decreased urine and headaches.
Severe dehydration is a medical emergency that can cause low blood pressure,
rapid heartbeat and even delirium or unconsciousness.
How much water each person needs varies a bit, but a good rule of thumb is
just to get plenty of fluids and eat foods high in water such as fruits and
vegetables.
Miller says water can also help keep calories in check during the holiday
season, since people sometimes feel hunger when they actually need fluids.
She says at holiday parties “it can be a great strategy to have one glass of
water or seltzer with every alcoholic beverage.”
