Short answer
Yes, a shower after an infrared sauna is a good idea. It rinses off sweat before the bacteria on your skin turn it into body odor, and it helps you cool down comfortably. There is no fixed waiting time: rest a few minutes, drink water, then rinse with lukewarm or cool water and moisturize if your skin feels dry.
Why shower after an infrared sauna?
An infrared session makes you sweat, and that sweat stays on your skin when you step out. Cleveland Clinic recommends rinsing off afterward: a shower washes away sweat, helps you cool down comfortably, and you will smell better too.
The smell is the main practical reason. According to Cleveland Clinic, sweat itself is odorless. Body odor appears when the water, salt and fat in sweat mix with the bacteria that live on your skin. Washing removes the sweat and some of those bacteria before an odor develops.
You may read that a post-sauna shower washes “toxins” out of open pores. The sources we checked do not support that. Think of the shower as hygiene and comfort, not as part of a cleanse.
Is it bad not to shower after a sauna?
It is not dangerous. If you are at home and plan to shower soon anyway, a short delay is fine. But sweat that dries on your skin and soaks into your clothes and towel is exactly what bacteria break down into body odor, so do not get dressed for the day or go to bed without at least a quick rinse.
In shared saunas, washing is also basic etiquette. InfoFinland tells sauna-goers to shower well before going in and to wash again after leaving the sauna for the last time. Many gyms have similar rules; 24 Hour Fitness, for example, requires members to shower before using its saunas. See should you shower before or after a sauna for the full routine.
How long should you wait to shower after an infrared sauna?
No official guideline sets a waiting time. Harvard Health advises cooling down gradually after a sauna and drinking two to four glasses of cool water. A practical routine is to sit for a few minutes, drink water, and shower once you have stopped sweating heavily, so you do not start sweating again as soon as you get dressed.
If you feel dizzy or light-headed when you stand up, sit or lie down before you shower and get help if it does not pass. Our guide to feeling dizzy or weak after a sauna explains what to do.
Warm, lukewarm or cold water?
| Water | What it is like | Keep in mind |
|---|---|---|
| Warm | Relaxing, good for washing off sweat and oil | Keep it short; the AAD suggests 5–10 minutes in warm, not hot, water if your skin is dry |
| Lukewarm or cool | Helps you feel less hot without a shock | A comfortable default for most people |
| Cold | Part of Finnish sauna tradition between rounds | Harvard Health advises cooling down gradually; ask your doctor first if you have a heart condition |
In Finland, a cold shower or a dip in the sea between rounds is common, as MyHelsinki describes. That is a matter of tradition and preference. If you want to try contrast showers or a cold plunge, start gently and read our guide to an ice bath before or after the sauna first.
A simple post-sauna routine
- Leave the sauna when you have had enough. Cleveland Clinic suggests beginners start at about 110°F for 5 to 10 minutes and that even experienced users keep sessions to about 20 to 30 minutes.
- Drink water. Harvard Health suggests two to four glasses of cool water after each sauna.
- Sit for a few minutes until you stop sweating heavily.
- Shower for 5 to 10 minutes in lukewarm or warm water. Use a gentle cleanser where you need it most, such as armpits and groin.
- Pat your skin dry with a clean towel and apply moisturizer while your skin is still slightly damp.
- Put on clean clothes and wash the towel and anything you sweated into.
Skin care after the shower
Heat and long, hot showers can leave skin feeling dry. The American Academy of Dermatology recommends limiting showers to five to ten minutes in warm water, patting your skin dry instead of rubbing, and applying a fragrance-free cream or ointment while your skin is still damp. Our guide to skin products before, during and after a sauna covers what to use, and do saunas dry out your skin explains why some people notice dryness.
Who should be careful
Harvard Health advises avoiding alcohol and medications that impair sweating before and after a sauna, and asking a doctor first if you have heart disease or uncontrolled high blood pressure. Cleveland Clinic says to leave right away if you feel dizzy or sick. For more on the rest of your routine, see what to do after an infrared sauna.
