Can a Warm Bath Help with Constipation?

Constipation affects around 1 in 7 adults in the UK, often leading to bloating, discomfort, and straining. While dietary fibre, hydration, and physical activity are first-line treatments, many people are surprised to learn that a simple warm bath may help relieve constipation symptoms.

In this article, we explore how warm baths can support digestion, reduce abdominal tension, and offer a gentle, natural way to help get things moving.

What Is Constipation?

Constipation is typically defined as having fewer than three bowel movements per week, hard or lumpy stools, or difficulty passing stool.

Common causes include:

• Low-fibre diets

• Dehydration

• Sedentary lifestyle

• Stress or anxiety

• Certain medications

Warm baths won’t replace medical treatment for chronic constipation, but they can be a soothing home remedy to support your overall digestive health.

How Do Warm Baths Help with Constipation?

1. Relaxing Your Abdominal Muscles

Warm water increases circulation and relaxes the smooth muscle tissue in your abdomen. This can reduce cramping, bloating, and help the intestines move stool more effectively.

2. Stimulating Bowel Movement (Peristalsis)

Warmth can encourage peristalsis—the natural, wave-like motion of your intestines that pushes stool along the colon. For some people, this gentle stimulation can prompt a bowel movement soon after soaking.

3. Reducing Constipation from Stress

Stress and anxiety disrupt digestion via the gut-brain axis. A warm bath is proven to lower cortisol, which helps reduce gut inflammation and improve bowel regularity.

4. Supporting Hydration Through Skin Absorption

Although not a replacement for drinking water, soaking in warm water may provide minor skin-level hydration, which complements your fluid intake and supports smoother bowel movements.

Can Epsom Salt Baths Help with Constipation?

Yes—Epsom salts contain magnesium sulfate, which may offer a mild laxative effect when absorbed through the skin (although more research is needed). Magnesium helps:

• Relax the colon

• Soften stool

• Encourage smoother movement through the bowels

How to use:

• Add 1-2 cups of Epsom salt to a warm bath

• Soak for 15–20 minutes

• Repeat 2–3 times per week as needed

💡 Tip: Always check with a GP before using Epsom salts if you have kidney problems or sensitive skin.

Warm vs Hot Baths: Which Is Better?

Both warm and hot baths can be effective, but extremely hot baths may cause dizziness or skin irritation. Stick to a comfortable 37°C–39°C temperature to maximise benefits without risk.

How to Incorporate Warm Baths into a Constipation Relief Routine

To improve results, combine warm baths with:

• A high-fibre diet (e.g. wholegrains, vegetables)

• At least 6–8 glasses of water daily

• Regular movement or walking

• A relaxing bedtime routine to reduce gut tension

🛁 Try soaking in a warm bath after dinner to help stimulate digestion before bed.

When to See a Doctor

While warm baths offer temporary relief, speak to a GP if you experience:

• Constipation lasting more than 3 weeks

• Blood in stool

• Unexplained weight loss

• Severe or sudden abdominal pain
