I don't think the Luddites were against creature comforts or worker safety. While folks currently invoke their name as you have, in fact the term Luddite refers to "a member of any of the bands of English workers who destroyed machinery, especially in cotton and
woolen mills, that they believed was threatening their jobs (1811–16)."
Workers of that era believed in and employed various forms of 'workplace protection' rudimentary though (and uncomfortable) they might have been.
Donning a smock is hardly the same as opposing automation and the loss of one's livelihood. Not having air conditioning in one's car is "suffering?" (e.g. "
the bearing or undergoing of pain, distress, or injury.")
If one wears his shirt inside-out, turns the collar inside, buttons the collar as well as those below and does not tuck his (or her) shirtails in her (or his) skirt, one can likely avoid the suffering using a large old paint-stained shirt. I've found that I can simply move the button on each sleeve to have the cuffs fit snuggly about my wrists - out of the way of the spinning blank, bit or blade at hand.
I condition the air in my shop by judiciously opening (and closing) windows or doors and, in extreme cases, powering up the three recycled ceiling fans mounted above me. I admit to employing a propane 'torpedo' heater in the dead of Winter and adding long johns to the mix, above. (I do NOT operate teh heater while working in teh shop. I run it for fifteen minutes or so to heat the interior and contents, then shut it down to come in and work - I insulated the heck out of the shop when I built it. Once I heat it up, it's good for a couple of hours easy.)
