Why I Switched to Warm Water in the Morning | Dr. Dennis Weekly Skip to main content

For years, I had a simple, go-to answer when asked during health talks:
“Drink whatever makes you feel good — we’re warm-blooded mammals, after all.”

That was my response — consistent, confident, and grounded in physiology. Whether the question came from an eager nursing student, a curious conference attendee, or a fitness enthusiast, I would shrug off the warm water hype and say, “If cold water wakes you up and feels right, go for it.”

But now… I’ve changed my mind.

🌅 My Morning Routine — Then and Now
For most of my adult life, I’ve started my day with cold water. Usually before a jog. The idea was simple: it felt refreshing, it “shocked” me awake, and it became a ritual.

But over time, something started to feel off. I’d notice a kind of sluggishness in the first 15–30 minutes of my morning run. A tight belly. A strange internal resistance. I brushed it off as age, schedule fatigue, or stress. Then — after yet another question about warm vs cold water during a corporate wellness talk — I decided to do what I hadn’t: actually test it.

The next morning, instead of reaching for the cold bottle in the fridge, I poured myself a mug of warm water.

Just warm — not hot, not boiled. The kind of warmth you’d expect from a caring grandmother offering comfort after a long day.

What happened after shocked me.

I felt lighter, more alert, and strangely, clearer-headed. My jog was smoother. My breathing was more rhythmic. No tight belly. No internal tension. Just flow.

And I’ve never gone back.

💧 But What’s Really Happening?
Here’s what I’ve learned — from experience, and now reinforced by science:

Warm water kickstarts your digestion gently.
It preps the gut without shocking it. Think of it like warming up your car engine — smoother start, better performance.

It promotes blood flow and circulation.
Warm water expands blood vessels slightly, improving flow — which may explain the improved physical performance and alertness I felt.

It supports detoxification.
Overnight, your body works hard — cleaning up waste, balancing hormones, and recharging cells. Warm water helps flush out that metabolic waste without triggering cold-shock response in your system.

It aligns with your core temperature.
Remember how I used to say, “We’re warm-blooded mammals”? Well, that’s still true. But that’s also exactly why warm water works better — it aligns with our natural body rhythm and doesn’t disrupt it.

🔄 Changing My Belief, Publicly
As someone who speaks on stages, writes policies, and trains health professionals, it’s not always easy to say, “I was wrong.”

But medicine, like life, is about evolution. I’ve now integrated this warm water habit into my own lifestyle and into my recommendations to others.

So if you’ve asked me this question in the past and heard the “just drink what feels right” answer — here’s the update:

“Start with warm water. Your body will thank you.”

💬 Try It Tomorrow
Here’s a simple 5-day challenge I give to clients and friends now:

Each morning, within 10 minutes of waking up, drink 300–500ml of warm water.

No lemon. No honey. Just warm, clean water.

Pay attention to your energy, digestion, mood, and clarity.

If you feel even half as good as I did, you may just change your habit for life.
