Apparently there are more saunas in Finland than cars, with just about every home having one installed somewhere in the basement or yard. Having sat in several Finnish saunas in my time, I can confirm that they’re hot. Very hot. And as for this idea that you have to run out into the sub-zero snow to cool down afterwards? Madness, is all I’ve got to say.

But when you think about it, these hot rooms are quite inefficient. Each and every one of us is a walking heat source (y’know, 37 degrees C?), so why shouldn’t we utilise that to keep ourselves healthy? Cue the Everlast Sauna Suit. This two piece, PVC suit with elasticated waist will not only make you look like a visiting alien invader from Mars, but will also help you sweat away the pounds while you exercise. Priced between $15 and $26 depending on size.

Just don’t wear one near Roswell, New Mexico!
