It’s interesting, there’s a ton of good publicity around sauna use, but not a lot of discussion around the pitfalls.

I’ve used the sauna off and on for a few years – and the biggest issue I run into are headaches after use.

Initially I thought I wasn’t drinking enough, and tried to hydrate myself out of the problem.

Whilst that may have been the case a couple of times, in general, it doesn’t work for me.

Instead, my best guess is that I’m staying in the sauna too long for my brain to cope.

What exactly is the physiological limit – I’m not sure. Probably something to do with the vasculature, and how the veins + heart respond to heat.

It’s definitely something to take seriously.

Now, my current approach is to bring a stop watch into the sauna with me, and try to figure out the sweet spot in terms of timing.

And then longer term, once I find a suitable thermometer, I’d like to cross-check the timing with the temperature.

If you’re in the same boat, and getting headaches, do take them seriously, and try to carefully figure out your upper limit of heat exposure.
