Wunderbar Hydration in Hot Weather for Older Adults: How to Stay Healthy This Summer
In the summer, when it gets hot, staying hydrated is especially important—particularly for older adults. The body loses a lot of fluid in the heat, and as we age, we often don’t feel thirsty until it’s too late. That’s why it’s easy to end up not drinking enough without even realizing it. This guide explains in simple terms what you should keep in mind.
Why Staying Hydrated Is So Important as You Age
Our bodies need water for everything to function properly—circulation, thinking, and digestion. In hot weather, you sweat more and lose even more fluid as a result. If this fluid isn’t replaced, you may feel dizzy, tired, and confused.
Important to know: As we age, we feel less thirsty. This is completely normal, but it has a consequence—we often don’t drink enough, even though our bodies need more. Experts say: Older adults tend to drink too little rather than too much.
How much should you drink?
On normal days, about 1.5 liters spread out over the day is sufficient. On hot days, organizations specializing in older adults recommend 2 to 3 liters because you lose more fluid through sweating.
One important exception: If your doctor has told you that you may only drink a certain amount due to heart or kidney issues, then stick to that advice and ask how you should manage during hot weather. This recommendation applies to healthy older adults, not to everyone.
How to Drink Enough Without Thinking About It
Since thirst isn’t always a reliable indicator, it helps to make drinking a regular habit:
- Set times: a glass with every meal, plus a few set times to drink throughout the day.
- Always within reach: Place a carafe or bottle where it’s clearly visible. You’re more likely to drink what you see.
- Drink the right things: water, unsweetened herbal or fruit tea, or juice mixed with plenty of water (one part juice, three parts water).
- Not ice-cold: Very cold drinks make your thirst go away faster—you’ll drink more if they’re lukewarm or at room temperature.
- Limited coffee, no alcohol: Both tend to dehydrate the body.
Warning Signs — Pay Close Attention Here
Dehydration is setting in. Watch for:
- dry mouth, dry lips
- dizziness or headaches
- fatigue, confusion, or restlessness
- dark urine and less frequent urination
If these signs appear: first, take a moment to calmly drink some water and sit down in a cool place.
Call 112 immediately if someone suddenly becomes confused, seems barely responsive, is having difficulty breathing, or loses consciousness. This could be a heat-related emergency and must be treated quickly.
Keep Your Home Cool
Drinking water alone isn’t enough in extreme heat. Keep your rooms cool:
- Below 26 degrees during the day, if possible; cooler at night
- Only ventilate when it’s cooler outside than inside—that is, early in the morning and late in the evening
- Keep windows shaded during the day with roller shutters, blinds, or curtains
Be Cautious with Medications
Some medications—for example, those for high blood pressure or diuretics—affect how the body copes with heat. If you take medication regularly, talk to your doctor about what you should be aware of during the summer. Store medications in a cool place; never leave them in a hot car.
For Family Members: How You Can Help
If you’re caring for an older person, there’s a lot you can do—without being overbearing: on hot days, briefly check to see if they’ve had enough to drink, place a bottle within easy reach together, or set up a gentle reminder. Some people use a hydration reminder app for this, which gently prompts them to drink and lets the family know that everything is okay. The goal is always the same: to help the older person get through the summer safely and remain independent.
