Can Running Make Eczema Worse?

Running is great for your heart, your lungs, and even your mood. But if you have eczema, you might notice something else after a jog itchy, red, irritated skin. So does running make eczema worse? The short answer is: it can, but it doesn’t have to. Let’s break down what’s really going on between cardio and your skin, and how you can keep moving without triggering a flare-up.

Why Eczema Flares Up During Exercise

Eczema, also known as atopic dermatitis, is a chronic condition that makes your skin dry, sensitive, and prone to inflammation. When you’re working out especially during cardio like running your body heats up. You start to sweat. That’s where the trouble begins.

Sweating and eczema don’t always get along. Sweat is salty and can dry out your skin even more. It can also irritate your already-sensitive skin barrier, leading to itching and redness. If your sweat mixes with bacteria or if it dries and leaves salt behind, an exercise eczema flare up can happen fast.

Here are some common eczema triggers during exercise:

• Increased body heat
• Sweating and salt buildup
• Friction from clothing or repetitive movement
• Outdoor allergens like pollen
• Chlorine from pool workouts

If you’ve noticed your eczema gets worse after running, one or more of these factors could be to blame.

How Running Can Affect Your Skin

Running boosts circulation and helps flush toxins, which sounds like a good thing for your skin. But if you’re running with sensitive skin, the benefits can come with challenges.

Let’s look at how running and eczema interact:

• Heat buildup: Your skin gets warmer as you run, which can trigger itchiness
• Moisture loss: Sweat evaporates and pulls moisture from your skin, leaving it dry
• Friction: Seams, straps, and skin-on-skin contact can cause micro-tears or irritation
• Environmental exposure: Running outside means contact with pollen, pollution, and sun all possible eczema triggers

So does running worsen eczema? It depends. For some people, cardio can actually improve skin by reducing stress and inflammation. For others, it leads to flare-ups. The key is learning how to manage it.

Tips for Running with Eczema

You don’t have to give up your workouts. With a few smart adjustments, working out with eczema can be more comfortable and less risky for your skin.

1. Prep Your Skin Before You Run

Think of your skin like your gear. It needs prep too.

• Apply a light, fragrance-free moisturizer about 30 minutes before your run
• Use a barrier cream on areas prone to chafing like underarms or behind knees
• Avoid heavy ointments right before running they can trap heat

2. Choose the Right Workout Clothes

Your clothing matters more than you think. To prevent irritation:

• Wear loose, breathable fabrics like cotton or moisture-wicking blends
• Avoid rough seams or scratchy tags
• Wash workout clothes in fragrance-free, hypoallergenic detergent

3. Keep Sweat in Check

You can’t stop sweating, but you can manage it.

• Gently blot sweat with a clean towel while running
• Take breaks in the shade or indoors to cool down
• Shower right after your run to rinse off salt and bacteria

4. Moisturize After Your Workout

Post-run care is just as important as pre-run prep. After your shower:

• Pat your skin dry with a soft towel
• Apply moisturizer while your skin is still slightly damp
• Use products made for sensitive or eczema-prone skin

This step helps lock in hydration and calm any irritation before it gets worse.

The Link Between Cardio and Skin Health

Here’s some good news. Regular cardio may actually help improve your skin over time. Exercise boosts blood flow, reduces stress, and can support your immune system. All of these are good for managing eczema.

So while cardio and skin health can be a tricky combo, it’s not all downside. The key is knowing how to balance your routine with your skin’s needs.

What Causes Eczema Flare Ups When Running?

Everyone’s skin is different, but here are some common causes of eczema flare ups during cardio workouts:

• High heat or humidity
• Cold, dry air
• Wearing the wrong fabric
• Not moisturizing before or after running
• Letting sweat sit too long on your skin
• Using fragranced or harsh body products

If you’re not sure what’s causing your flare-ups, keep a skin journal. Track your runs, your skincare routine, and how your skin reacts. Patterns will show up fast.

Should You Stop Running If You Have Eczema?

Not necessarily. In fact, quitting exercise completely could make things worse. Stress is a major eczema trigger, and running helps lower it. Plus, regular movement supports your overall health, which affects your skin too.

Instead of quitting, try adjusting:

• Run during cooler times of day
• Switch to lower-impact workouts on flare-up days
• Focus on indoor cardio if pollen or pollution is high outside

You can still stay active and protect your skin. It just takes a bit more planning.

Quick Takeaways

• Running and eczema can be a tricky mix, but it’s manageable
• Sweating, friction, and heat are the main triggers during exercise
• Prep your skin before and after workouts to prevent flare-ups
• Choose breathable fabrics and avoid harsh products
• Running is still good for your skin if you manage the risks
