Safety, contraindications and screening
Can I have an ozone sauna session during my period?
No. Menstruation is a contraindication for ozone sauna sessions. If you are having your period, wait until it has finished and then book as normal — there is no additional waiting time afterwards. Operators ask about it at intake as a routine screening question, alongside pregnancy, medication and the rest of your health history.
The position. Do not have an ozone sauna session while you are menstruating. Wait until your period has finished, then book as you normally would. Nothing else changes: there is no reduced ozone level or shortened session that makes it suitable, and no extended wait once the bleeding has stopped.
Why it is on the list. Ozone thins the blood, which is the reason active bleeding from any site sits on the contraindication list, and menstruation falls under that heading. The heat is a second factor: a 30-minute steam session widens blood vessels and raises heart rate.
For operators. This is an ordinary screening question and it should be asked in the same tone as any other, at each visit rather than once at sign-up.
- Ask directly, and record the answer on the intake form.
- Where the answer is yes, offer the next date after her period is due to finish. Do not offer a reduced-intensity session instead.
- Where a client also reports unusually heavy bleeding, a clotting disorder, anticoagulant medication or a recent gynaecological procedure, refer her to her doctor before booking at all.
- Moving a session costs nothing on theBooking.site — bookings can be moved or rebooked at no additional charge by the outlet — so rescheduling need not be an awkward conversation.
Related exclusions. Pregnancy is separate and absolute: no sessions at any point in a pregnancy, and none until after the birth and after breastfeeding has stopped. Active bleeding from any other site, platelet disorders including haemophilia, and thrombosis are permanent exclusions rather than timed ones. The list of who should not use an ozone sauna carries the rest.
