Yes. Shower soon after a run, once you've walked for a few minutes to cool down. Dermatologists suggest showering immediately after a workout, and if you can't, changing out of your sweaty kit is the next best thing. But maybe you're wondering whether the 40 minutes you just spent on the sofa in damp shorts was a problem, or what to do when there's no shower nearby.
This article is part of our runner's hair and body care guide. We make 3-in-1 bars, we're not doctors, so every health fact comes from a source listed at the end.
Should you shower right after a run?
Yes, as soon as you reasonably can. The dermatology advice is to consider showering immediately after your workout, because this may rinse away bacteria that can cause acne. Put in everyday terms, there's a reason showers typically follow a five-mile run. Sweat, natural oils and dead skin cells build up on your skin, and that creates an environment for bacteria and fungi to thrive and produce an unpleasant smell. If you've ever opened a kit bag two days after a long run, you've met the result.
So "right after" is the goal. Just not the very second you stop your watch.
How long should you cool down first?
Give it 5 to 10 minutes of easy walking. After exercise your heart is still beating faster than normal and your body temperature is higher. Stop dead and you can feel light-headed, because your heart rate and blood pressure drop rapidly. The heart health advice: slow to a walk for 5 to 10 minutes.
You probably know the other reason from experience. Jump under the water the moment you get in, and you step out still glowing, pulling a clean T-shirt over a back that's already damp again. So walk the last few hundred metres and drink some water first.
What happens if you wait?
None of the sources we checked gives a deadline in minutes, so we won't invent one. What they do describe is what can build up while you sit around in damp kit:
- Smell. Armpits, feet and groin are particularly prone, because they stay warmer and have more sweat glands, which promote bacterial growth.
- Breakouts. Dermatologists describe sweat pimples as the result of oil, bacteria, heat and friction working together to clog your pores.
- Chafing. Doctors list promptly removing wet clothes among their tips to prevent chafing. Wet shorts don't stop being wet shorts just because you've sat down.
- Feet. Wet or sweaty feet make you more likely to get athlete's foot.
Notice what these have in common: the damp kit, more than the missing shower. That's also why the dermatologists' fallback is to change out of your workout clothes. (Alexandre here, the founder. As someone who sells bars for a living, I'll be honest: what you wash with matters far less to me than you getting out of that wet T-shirt.)
Still, "shower as soon as you can" only works if your wash kit is where you are. The club shower is no use if last week's bottle leaked into your towel and you quietly stopped packing it. That's the gap a solid bar fills: one bar for hair, body and face, with nothing in it to spill.
Shampoo, body and face wash, all in one bar. Cooling, refreshing and designed for those always on the go.
Whatever you wash with, the next question is the dial on the wall.
Hot, warm or cold: which shower is best?
Warm and short is the safe default. Dermatologists say the water should be warm, but not too hot, because very hot water can dry out your skin and make it itchy. The advice is also to keep showers under five minutes.
What about a cold shower for tired legs? A review of 17 small trials found some evidence that cold-water immersion reduces muscle soreness after exercise, compared with rest. But it tested immersion in water below 15°C, so cold baths rather than showers, and rated the study quality as low. Our reading: finish cool if you like how it feels, and don't worry if you don't.
Put together, it looks like this:
| Your situation | What to do |
|---|---|
| Shower at home or at the club | Walk 5 to 10 minutes, then a short, warm shower |
| A drive or ride home first | Dry top and dry socks before you set off |
| Straight to work, only a sink | Change fully, then wash face, armpits, groin and feet |
| No shower until tonight | Full change now, proper wash later |
What if you can't shower straight away?
Change first, then wash the important bits when you can. Keep a dry top, underwear and socks in the car or at the bottom of your work bag, and those days stop being a problem.
When a sink is all you have, the only areas you consistently need to wash are your face, armpits and groin, and the standard health advice on body odour adds your feet.
The office is where it gets fiddly, because your running bag is suddenly also your work bag. A shower gel that pops open next to your laptop charger is nobody's idea of a good morning. A solid bar in a ventilated tin or mesh pouch has nothing in it to leak.
Shampoo, body and face wash, all in one bar. Keep your hair and skin healthy on the go. Monoï-infused scent with a touch of vanilla. Designed for those always on the go.
Bar or bottle, each situation has its own tricks. If your run ends at your desk, read running before work: a 10-minute office shower routine. If it ends at a finish line, race day toiletries has the bag list. And for hair, there's how to wash your hair without a shower.
Do you need to wash your hair after every run?
No, not automatically. Dermatologists advise washing your hair based on how often it gets dirty or oily: possibly every day if you have straight hair and an oily scalp, and when needed, at least once every 2 to 3 weeks, if your hair is dry, textured, curly or thick. So the shower after a gentle 30 minutes doesn't have to be a hair wash. We go deeper in how often runners should wash their hair, and washing your hair when you train every day covers the daily version.
What should be in your bag?
Five things, and you're covered almost anywhere.
- A small towel, the one you always forget.
- Flip-flops. The standard health advice is to wear them in changing rooms and showers to avoid athlete's foot.
- Dry clothes, socks and underwear included.
- A sack for wet kit.
- Something to wash with.
That last one is where bags get crowded. Shampoo, shower gel and face wash are three bottles to remember, which is usually how they end up staying at home. One solid bar covers all three.
Shampoo, body and face wash, all in one bar. Cooling, refreshing and designed for those always on the go.
Whichever you pack, let it dry between runs (how to store a soap bar explains how). The same goes for your cap and headband, which get their own guide in sweaty caps and headbands.
Summary
Should you shower right after a run? Yes: cool down for 5 to 10 minutes, then take a short, warm shower. If you have to wait, change into dry clothes and wash when you can.
Keep a towel, flip-flops, dry clothes and something to wash with in your bag, and the question mostly answers itself.
Frequently asked questions
How long after a run should you shower?
As soon as you've cooled down. The heart health advice is 5 to 10 minutes of slower walking after exercise, and dermatologists suggest showering immediately after a workout.
Is it bad to shower immediately after running?
The shower isn't the issue, stopping suddenly is. That can make you light-headed. Walk for a few minutes first.
What happens if you don't shower after a run?
None of the sources we checked gives a deadline in minutes. What they describe is what can build up while you sit around in damp kit: smell, sweat pimples, chafing and a higher chance of athlete's foot.
Why do you get spots after running?
Dermatologists describe sweat pimples as the result of oil, bacteria, heat and friction working together to clog your pores. Showering immediately after a workout may rinse away bacteria that can cause acne.
What if you can't shower after a run?
Change out of your running kit, which is what dermatologists suggest. Then wash your face, armpits and groin, the areas that need consistent washing, at the first sink you find.
Is a cold shower better after a run?
Not proven. A review found some evidence that cold-water immersion reduces muscle soreness after exercise, but the trials were small and low quality, and they tested cold baths, not showers.
Should you take a hot shower after a run?
Warm and short is the safe default. Very hot water can dry out your skin and make it itchy, and the advice is to keep showers under five minutes.
Should you wash your hair every time you run?
Not automatically. Dermatologists advise washing your hair based on how often it gets dirty or oily, so the shower after a gentle 30 minutes doesn't have to be a hair wash.
What should you pack for a shower after a run?
Five things: a small towel, flip-flops, dry clothes with socks and underwear, a sack for wet kit, and something to wash with.
Can you use one bar for hair and body after a run?
That's what a 3-in-1 bar is: one solid bar for hair, body and face. Every Rinsed bar contains fragrance (Parfum). See how to use a shampoo bar.
