Why staying hydrated is harder, and more important, as we age
Dehydration is common and serious
Up to 40% of older adults are chronically under-hydrated. Dehydration can cause confusion (often mistaken for dementia), falls, UTIs, kidney problems, and hospitalization. Yet thirst sensation decreases with age, so they don't feel thirsty even when they need fluids.
Gently pinch the skin on the back of the hand and let go. In a hydrated person, skin snaps back immediately. In dehydration, it stays "tented" for a few seconds. Note: This test is less reliable in elderly due to normal skin changes.
Urine color is a good hydration indicator:
Note: Some medications and vitamins can change urine color.
Practical strategies that work
Most older adults need 6-8 cups (48-64 oz) of fluids daily. May need more if:
Note: Some conditions (heart failure, kidney disease) require fluid restrictions. Check with doctor.
Place a water bottle or cup within reach at all times. Out of sight = out of mind.
Use phone alarms, medication times, or meals as cues to drink.
Water, tea, coffee, juice, milk, soup, popsicles. Whatever they'll drink counts.
Watermelon, cucumbers, oranges, grapes, soup, yogurt, jello all contribute fluids.
Some prefer ice water, others room temperature or warm. Ask what they like.
Sipping throughout the day is easier than drinking large amounts at once.
Glass of water first thing in morning, with each meal, with medications, at bedtime.
Lemon, cucumber, or fruit slices make water more appealing to some.
Cutting fluids doesn't solve incontinence, it concentrates urine, which irritates the bladder and can make leakage worse. Better strategies:
Severe dehydration often requires IV fluids in a medical setting.
