Why Warm Nutrition Matters: The Digestive Science Behind Hot Drinks

Cold drinks can feel refreshing. But for a lot of people, they also feel a little jarring, especially on an empty stomach. 

If you’ve ever downed an iced coffee or cold smoothie first thing in the morning and felt a little sloshy, you probably know what we mean. It’s slightly uncomfortable in a way that’s hard to explain but easy to recognize.

So does temperature affect digestion? And are warm drinks actually better for digestive comfort than cold ones?

Let’s take a closer look at why hot drinks may feel easier on your gut, and where bone broth fits into the bigger picture of warm nutrition.

☯️ DO HOT DRINKS HELP DIGESTION? TRADITIONAL MEDICINE SAYS YES

In Traditional Chinese Medicine (TCM), the stomach is often compared to a “cooking pot” or “digestive fire.” For your body to extract nutrients, that “fire” must be hot enough to break down food.

According to practitioners, drinking warm water helps sustain that fire, while iced drinks are seen as throwing water on it, which may lead to bloating, fatigue, and sluggish digestion.

But is there any science to back this up?

🫖 ARE WARM DRINKS BETTER FOR DIGESTION? 

A recent 2025 study became the first in the US to directly link cold and hot dietary consumption to multiple health outcomes.[*] In it, researchers examined more than 400 Asian and white adults across the US. 

They discovered that higher cold drink consumption among Asian participants during the summer was associated with increased anxiety, more sleep disturbances, and greater feelings of abdominal fullness.[*]

In contrast, white participants who drank more hot beverages in winter reported lower levels of depression, improved sleep quality, and fewer digestive symptoms.[*]

Tianying Wu, the study’s lead author, said, “Something as simple as the temperature of what we eat and drink can have real impacts on health.”[*] 

🔥 SO, HOW DOES TEMPERATURE AFFECT DIGESTION?

Digestion isn’t just about enzymes and nutrients. Your digestive system is tightly connected to your nervous system, and it’s sensitive to cues like stress and temperature.

That’s where things get interesting — because warmth and cold don’t send the same message to your gut.

⚡ COLD DRINKS: SOMETIMES MORE JOLT THAN HUG

Cold drinks wake things up. They’re stimulating and honestly great when you’re trying to feel more alert or power through an afternoon slump.

But that same jolt isn’t always what your digestion wants, especially if you’re sipping something icy first thing in the morning, on an empty stomach, or during already stressful days.

Some research suggests that cold beverages may increase digestive discomfort for people with more sensitive guts, including those prone to bloating or IBS-type symptoms.[*] 

☕ WARM DRINKS BRING THE COZY

Your vagus nerve is basically the main highway of your parasympathetic nervous system, also known as your body’s rest-and-digest mode. Its fibers send information between your brain, heart, and digestive system.[*]

When that system is active, everything softens a bit. Muscles unclench. Blood flow shifts toward your gut instead of preparing for fight-or-flight. And your digestion can just do its thing.

Warmth is part of this story. According to studies, the sensory neurons in your gut are highly responsive to temperature, with many of them activating specifically when things warm up.[*] 

That helps explain why warm drinks usually feel calming for your stomach. They don’t magically fix digestion, but they can help your body relax enough for digestion to feel smoother, steadier, and less reactive.[*]

🍵 WHAT ABOUT WARM AND HOT DRINKS FOR CONSTIPATION?

Your digestive tract relies on steady, wave-like muscle contractions (called peristalsis) to move food through your stomach and intestines.[*] When those muscles are tense or sluggish, digestion can feel… stuck.

Warm drinks help those muscles relax and move more smoothly.[*] Research suggests warm and hot beverages also speed up gastric emptying, meaning food moves out of your stomach more efficiently than it does with cold drinks.[*]

When food lingers too long, you’re more likely to feel bloating, pressure, or that heavy, uncomfortable feeling after meals. 

That’s why warm and hot drinks often show up in chats about digestion, bloating, and upset stomach. The warmth supports normal movement patterns without irritating or overstimulating your system, which can be super helpful when digestion feels slow or backed up.

So if warm drinks tend to feel easier on your gut, using bone broth for digestive health is a natural place to zoom in next.

🍲 BONE BROTH FOR DIGESTION: SIMPLE SCIENCE, REAL COMFORT

Bone broth is easy for a lot of stomachs to get along with. And while there are tons of science-backed benefits of bone broth for gut health, today we’re focusing on one question:

Is bone broth good for digestion? 

YES, BECAUSE IT’S GENTLE NUTRITION

Bone broth starts with a simple process: slowly simmering animal bones (and sometimes connective tissue) to pull amino acids, collagen, and minerals into a warm, savory broth. Nothing fancy or aggressive.

That simplicity is a big part of why bone broth tends to feel easy to digest. Here’s what’s working in its favor:

✅ It’s liquid. Liquids are already easier for your digestive system to handle than solid foods. There’s no chewing, no mixed textures, and less mechanical work required up front. For many people, that alone makes digestion feel smoother.

✅ It delivers real nutrition without heaviness. Bone broth provides protein in liquid form, which can feel more approachable than dense or complex meals, particularly when your appetite is low or your tummy feels sensitive. 

Our Instant Bone Broth provides 10 grams of protein per serving. So you’re getting nourishment without asking your stomach to do extra work. 

✅ The ingredient list stays short and familiar. Bone broth is typically made from just a few whole-food ingredients. That simplicity can help reduce sensory overload for your gut and make it easier to nourish yourself without relying on heavily processed options.

YES, BECAUSE IT KEEPS YOU HYDRATED

Dehydration can lead to constipation and more difficult bowel movements (sorry for the TMI).[*]

When you don’t drink enough fluids, your gut starts pulling extra water from your food as it moves along. This can make things drier, slower, and harder to pass. And that’s a recipe for bloating and discomfort.

Bone broth helps because it hydrates and brings backup.

Along with fluid, bone broth naturally contains electrolytes like sodium, potassium, and a bit of magnesium. Electrolytes help your body hold onto water and even support the muscle contractions your digestive tract uses to keep things moving.[*]

It’s why drinking bone broth for bloating, digestive issues, or just better gut health often feels more supportive than water alone.

📝 HOW TO DRINK BONE BROTH FOR GUT HEALTH AND DIGESTIVE COMFORT

Now that the link between bone broth and digestive health makes sense, let’s talk about how to actually use it for warm, nourishing drinks.

LET IT FIT WHERE IT FEELS EASY

Bone broth doesn’t need to be consumed in excess to be useful. Many people find it works best:

• In the morning, before solid food or instead of coffee

• Between meals, when you want something satisfying without full-on snacking

• During stressful days, when digestion feels a little more reactive

• When you’re bloated or not quite hungry, but still want nourishment

• After dinner, as a warm way to wind down and curb late-night grazing

These are moments when your digestion wants support, and bone broth fits without forcing anything. And if you like a little variety, a few small flavor tweaks go a long way.

KEEP IT WARM, NOT SCALDING

Warm means comforting — not tongue-burning hot.

Bone broth is best sipped slowly at a temperature that feels pleasant and grounding. Some research suggests that warm beverages in the range of 130-160°F tend to hit that sweet spot.[*] 

This gives your body time to register the warmth, take a minute to relax, and ease into digestion, instead of reacting to something too hot or rushing the process.

CONSIDER A BONE BROTH CLEANSE OR FAST

A short bone broth cleanse or fast can create a pause when your gut feels bloated, unsettled, or irritated. 

By temporarily removing harder-to-digest foods, bone broth becomes the main input, giving your gut a break while still providing nourishment. 

Because it’s warm, hydrating, and easy to digest, some people use this approach as part of a short reset for bloating, digestive discomfort, or leaky gut support.
