The episode, word for word
That's the most common pushback I get when I talk about hydration. People say, "Neil, I'm not not drinking water. I drink coffee in the morning. I have tea at lunch. I grab a bottle of water at some point during the day. I'm not walking around like a dried-out sponge in the Sahara."
And I believe you. You're probably drinking some water.
But here's the problem: some water isn't enough. For most people with T1D, "some water" is about 2, 4 cups a day. And the protective threshold, the point where hydration actually starts reducing your complication risks, is closer to 8, 10 cups.
That's a gap of 4, 8 cups. And that gap is costing you.
Today we're talking about how to add just three more glasses to your day, and why it matters more than you think.
My name is Neil Greathouse, and this is Your Best T1D Year.
Alright, welcome to Week 5 of the Hydration Challenge: Refilling What T1D Drains. If you're just joining us, you're not behind. Jump in right now. Drink more water than you did last week.
So let's talk about the pushback. Because I've been getting messages from people saying, "I already drink water. Why isn't that enough?"
Here's the truth: most people with T1D drink about 2, 4 cups of plain water per day. That's not zero. That's something. But it's not enough to move the needle on long-term health.
The research shows that drinking 8, 10 cups per day, about 2, 2.5 liters, is where you start seeing real benefits:
Lower vasopressin (which stabilizes blood sugar)
Better kidney protection (50% lower CKD risk at 3.2 liters/day)
Improved cognitive function
Faster insulin absorption
So if you're drinking 2, 4 cups now, you're not at zero. But you're also not at the protective threshold. You're in the gap. And closing that gap is easier than you think.
Let's say you're drinking 3 cups of water per day right now. Your goal is to get to 6. That's three more glasses. That's it.
Here's how:
Glass 1: Morning Anchor
Drink one full glass of water as soon as you wake up. Before coffee. Before checking your CGM. Before scrolling Instagram.
Keep a glass or a bottle on your nightstand. Fill it before bed. When your alarm goes off, drink it.
Why? Because you've been dehydrated for 6, 8 hours. Your body needs water first. Coffee is a diuretic, it makes you pee more. So if you start your day with coffee, you're compounding dehydration before you've even rehydrated from the night.
Water first. Coffee second.
That's glass one.
Glass 2: Midday Reset
Set an alarm for 2pm. When it goes off, drink one full glass of water.
Why 2pm? Because that's when most people hit the afternoon slump. You're tired. You're distracted. You're thinking about snacks. And a lot of that fatigue is dehydration, not hunger.
Drinking water at 2pm resets your energy. It clears brain fog. It keeps your insulin absorption steady for the rest of the day.
That's glass two.
Glass 3: Pre-Meal Hydration
Drink one full glass of water 20 minutes before dinner.
Why? Because it increases subcutaneous blood flow, which helps your mealtime insulin absorb faster. It also helps your kidneys handle any post-meal blood sugar spikes.
Plus, it's an easy habit to stack. You're already prepping dinner. You're already thinking about your meal bolus. Just add water to the routine.
That's glass three.
Three more glasses per day doesn't sound like much. But over a week, that's 21 extra glasses. Over a month, that's 90 extra glasses. Over a year, that's over 1,000 additional glasses of water your body didn't have before.
And those 1,000 glasses add up:
Lower vasopressin = more stable blood sugar
Better kidney function = lower complication risk
Improved cognitive function = fewer brain fog moments
Faster insulin absorption = more predictable corrections
You shouldn't have to overhaul your entire life just to protect your kidneys. And you won't need to, if you just add three more glasses to your day.
Real quick, if you're thinking, "Neil, I'm already overwhelmed. I can't add one more thing," I need you to hear this.
