I have used sauna for several years about 4-5 times per week - it helps me tremendously with depression and insomnia. Post vitrectomy, I am carefully considering all of my prior activities before resuming. I am concerned that the heat may cause the scleral buckle to degrade over time - decades maybe - but I wish to avoid having another surgery to remove/replace it if possible. I use sauna at 150-160 F. and stay in for about 15 minutes - just enough to break a nice sweat. Thank you.
