The United States seems to be the only place where the sauna is not enjoyed as a meditative and restorative part of your routine. People show up in their sneakers and fully clothed with headphones blaring, scrolling facebook and instagram, instead of taking some time to unplug and just enjoy the moment (and let the people around them do the same).
I go to the sauna after my workouts to meditate and have some quiet thinking time to allow my body to enter a recuperative parasympathetic state... but I have yet to have a dry sauna session where there isn't at least one person in there listening to loud headphones, possibly even tapping their feet to the beat.
So I'm making a call to everyone - leave your devices in your lockers. Not only is it better for you to unplug and get used to some "unentertained" time (seriously, it's only 15mins for the average person), it's not putting unnecessary heat wear on your device. It's also considerate to the people who have to share the sauna with you.
