Sat in a damp London flat, with condensation permanently dripping down the windows (despite the dehumidifier running virtually 24/7), I struggle to relate to a world where you would deliberately want to put moisture into the air.
We run our aircon on the de-humidify setting haha
Also because our winters never get cold enough to freeze all the moisture out of the air - I experienced that when living in an alpine village that turned into a giant ice box over winter / early spring (Arthur's Pass), but that was a village of 37, the rest of NZ is not experiencing that.
Heck, I used to run two dehumidifiers in a previous house of mine during winter, just because the amount of condensation and dampness we got was ridiculous and very unhealthy.
