One of the sneaky things about getting older is that your body may stop reminding you that you need to drink.
In other words, “I'm not thirsty” doesn't necessarily mean “I'm well hydrated.”
As we age, several things can make dehydration more likely:
💧 Our thirst response becomes less sensitive. You can need fluids without getting that strong HEY, DRINK SOMETHING signal you may have had when you were younger.
💧 Our kidneys aren't quite as good at conserving water. With age, the kidneys generally become less able to concentrate urine when the body needs to hang onto fluid.
💧 We tend to have less total body water. And here's where one of my favorite subjects makes yet another appearance: muscle. 😂 Muscle tissue contains substantially more water than fat tissue. As we lose muscle with age, we also lose some of our body's water reserve.
That means a relatively small fluid loss can have a bigger impact than it once did.
Dehydration can show up as fatigue, headache, dizziness, weakness, confusion or a drop in blood pressure—and dizziness plus reduced strength and balance is a particularly lousy combination as we get older.
So what do we do?
Don't rely entirely on thirst.
Keep water where you'll actually see it. Drink regularly throughout the day. Have some with meals. Pay extra attention when you're exercising, spending time in hot weather, sick, or losing more fluid than usual.
And—yes, here I go again—keep working on maintaining your muscle. 💪
Strength training isn't just about looking toned or lifting heavier things. Maintaining lean mass is part of maintaining the resilient, functional body we want to carry with us as we age.
So if that water bottle has been sitting beside you untouched for the last four hours because “I'm just not thirsty…”
This is your reminder to pick the dang thing up. 😂💧
