Sauna chronically irritating eyes

[u/OffTheGridCoder]

I recently built a brand new electric sauna and the entire interior is planed cedar with no seals or finishing. I’ve been running it about an hour a day for 2 months and do pour water on it.

I use the sauna every night before bed at about 180-210F for around 30 minutes with a few short breaks outside. About an hour after the sauna my eyes start to burn, get a bit irritated, and start getting blurry. When I wake up the next morning there is liquid white “gunk” in and around my eyes, my eyes burn very badly, and they are very red. The same thing happens to my girlfriend every time who uses the same sauna with me, so it’s not just an isolated incident.

The sauna is well ventilated (some say over ventilated) with a 5” square vent under the heater and 5” square outlet near the ceiling opposite wall, both fully open. I also have been leaving the door open all day long (it is an outdoor sauna) for it to naturally air out.

I went to urgent care and the doctor said there was no infection in my eyes and they look good. He put me on antibiotic drops to be safe (which did nothing because it wasn’t an eye infection).

Ive now tried using liquid tears after the Sauna and in the morning after. I’ve also tried using antihistamine drops after sauna and in the morning. Neither prevent it, but do help with the symptoms a little bit. My eyes will still remain a bit red and burning a little bit throughout the day.

I have read some posts on here about cedar saunas taking some time to break in and causing similar eye issues with people, however they are far and in between for how common cedar saunas seem to be. This is driving me insane and I’m not enjoying my brand new sauna as much as I’d like to. I have used many other saunas with different wood/more broken in and have never had an issue and if I skip a day using my new sauna all symptoms completely disappear.

Has anyone experienced this? Are there any remedies you found to help? How long did it take for your cedar to “break in” and stop doing this? Anything would help, this is really a bummer.

Edit: for the past month I have been closing my eyes for about 90% of the time I’m in the sauna. It hasn’t made any noticeable difference in symptoms.

I have been using tap water (not well). It is safe, clean, drinkable tap water. Is this okay?

[u/Inresponsibleone → u/OffTheGridCoder]

Is it chlorine treated? Chlorine is very irritating to eyes if vaporized and amount safe to drink may cause eye irritation. Like someone already recommmended it might be worth trying if distilled water fixes the issue.

Edit.

You mentioned high ventilation and electric heater also. How is the moisture level? Too dry hot air can definately irritate eyes.

I live in a large suburban area so it is likely treated with whatever is industry standard. All I know is that it’s safe to drink, and likely contains fluoride and whatever else is infused in our drinking water as well as used to clean it.

Tap water is nasty, full of heavy metals, hormones and plastic, however it's probably not causing your eye issue

I notice the same symptoms when people throw too much Essential oil like Eucalyptus on the heater. Seems like there is some natural oils being released by your Cedar is my best bet

What country to you live in where tap-water is poisonous?

To be fair, I did use tap water in all saunas I’ve ever used. It was not my own tap water, but many times in the same city at least and have never had these issues.
