Short answer
There is no safe UV tan, and changing the order of a sauna and a sunbed does not remove UV risks. For self-tan, follow the exact product’s development and aftercare instructions; a first rinse is not a universal sauna clearance. Skip sauna bathing while sunburn is healing.
UV tanning, sunburn and cosmetic self-tan are different situations. This guide separates them instead of recommending a combined tanning-and-sauna routine. It is general information, not medical advice.
Should you use the sauna before or after tanning?
Neither order makes UV tanning safe. The FDA explains that a UV tan is a sign of skin damage. We do not recommend a sauna-before-sunbed schedule or a waiting time that supposedly removes that risk.
If you are spending time outdoors, protect your skin from UV independently of any sauna visit. A sauna is not sunscreen, and feeling cool after a session is not evidence that UV exposure is safe.
Can you use a sauna after tanning or sunbathing?
Do not use the absence of redness immediately after sun exposure as a safety test: the FDA notes that sunburn effects can develop later. If you have sunburn, avoid sauna heat while it heals. The NHS sunburn guidance focuses on cooling and protecting the skin, not adding heat:
- sponge sore skin with cool water or take a cool bath or shower
- apply a soothing aftersun cream or spray, such as aloe vera
- stay out of the sun until all signs of redness have gone
- get medical help if you feel unwell or the skin swells badly or blisters
Heat can also leave skin feeling dry. Our guides on whether saunas dry out your skin and whether an infrared sauna can burn your skin cover that in more detail.

We do not recommend either order with a tanning bed. The NHS sun-safety guidance advises against sunbeds. A sauna before or after one does not remove the risks of UV exposure.
Some medicines also make skin more sensitive to light. The NHS lists tetracycline antibiotics as one example, including sensitivity to sunbeds and sun lamps. If you take any regular medicine, ask your pharmacist before sunbathing or tanning.
Can you use a sauna after a spray tan?
A first shower is not a universal clearance. Follow the development and aftercare instructions for the exact product or professional treatment. For example, St. Tropez distinguishes its Classic, Express and no-rinse ranges and gives different instructions about rinsing and sweating. These directions concern cosmetic colour development; they do not establish medical fitness for sauna use. If your instructions do not address sauna or steam, ask the product maker or salon before combining them.
Does a sauna make you tan?
Sauna heat is not a UV-tanning treatment. Cosmetic self-tanners are different again: they add colour without intentional UV tanning. Redness after heat should not be treated as a desirable tan or a reason to stay longer. For background, see does a sauna make you tan and infrared saunas and tanning.
Sun protection is separate from sauna timing
- Do not plan UV tanning as the next step in a sauna routine.
- Use shade and protective clothing outdoors; do not rely on sunscreen alone.
- If you shower after sauna use, treat that as washing, not a tanning preparation step. See showering around sauna use.
- Before you go into the sun, apply sunscreen. The NHS recommends at least SPF 30 and at least 4-star UVA protection.
- Reapply after sweating, swimming or towel drying, and spend time in the shade when the sun is strongest.
Apply sun protection whenever UV exposure requires it, including before an outdoor journey to a sauna. Reapply after sweating, swimming or towel drying; do not postpone protection simply because a sauna session is planned.
FAQ
Should you use the sauna before or after tanning?
Neither order makes UV tanning safe. We do not recommend combining a sauna session with a sunbed or deliberate sun tanning.
Can I go in the sauna with sunburn?
No. Avoid sauna heat while sunburn heals. Seek medical advice for blistering, swelling or feeling unwell rather than trying to treat the burn with heat.
Can I use a sauna after a spray tan?
Follow the exact product or salon’s development and aftercare instructions. Different products have different rinse and sweating instructions, so the first shower is not a universal sauna clearance.
Does a sauna help you tan?
No. Sauna heat is not a UV-tanning treatment, and redness from heat is not a goal to pursue.
Does sweating in the sauna remove sunscreen?
Sweating and towel drying can affect protection. Reapply sunscreen as directed and protect your skin whenever you are outdoors; do not delay protection until after a planned sauna.
