Beware of Dehydration This Winter

What you need to know about hydration and aging

During the summer, you're not likely to forget a cool glass of water. But do you remember to stay hydrated in the winter too? Thirst isn't as obvious in the winter. But you need to stay hydrated even during colder months.

As you age, you might not feel thirsty as often. Don't let your body fool you: Dehydration can be a common reason that seniors are hospitalized. Learn to recognize the signs of dehydration.

What is dehydration?

When your body doesn't have enough water, that's dehydration. It can be caused by diarrhea, vomiting, sweating too much, a fever, or simply not drinking enough water. It can cause serious problems like strokes, kidney stones, high blood pressure, muscle spasms, and more. Staying hydrated has many benefits like looser joints and supporting your liver and kidneys. 

You're at higher risk if you're older or have certain chronic illnesses. Watch out for signs like:

  • Feeling very thirsty

  • Dry mouth

  • Muscle cramps

  • Dry skin

  • Dark-colored urine

  • Feeling tired

  • Dizziness

Tips for staying hydrated

We have tips to help you fight dehydration. First, remember that you may feel hungry when you're thirsty. Make sure you keep a water bottle near you. Most adults need 8-12 cups of water, so sip and drink water with your meals throughout the day. It might be harder to notice dehydration in cool air. Because you're not hot or sweaty, dehydration can sneak up on you. For more advice about avoiding dehydration, contact your local VA dietitian.
