Turbulence and cabin temperature
 

No reference but I agree with compressor stall, remember when using North Sea ferry services in winter, the inside cabin was no place to be if one was feeling even only slightly nauseous, the cabin would be hot and airless and possibly foul smelling. Out on deck a blast of cold fresh air restored one to feeling normal very quickly. I too would crank the cabin temperature down a few degrees if in prolonged turbulence.

This is for smaller aircraft pilots, but the principles still apply: https://www.aopa.org/go-fly/medical-...otion-sickness

Motion sickness is the body's natural response to a disconnect between the middle ear's balance mechanism and other body senses of motion (muscle "position sensor" nerves, vision). In our evolution before "vehicles", the most likely cause for such a disconnect was ingesting poisonous food, so the evolved response is to empty the stomach ASAP. Perceived warmth (fever), a subnormal amount of oxygen (think: cyanide) and smells (rotted food) also make the body believe it is poisoned, so removing as many of those cues as possible is good.

That depends. I've seen some skippers do crazy things with the AC of the airplane. Ranging from not selecting APU bleed before main door opening in a 30ºc destination (and before external AC being connected) to "save fuel/money/whatever" to others going crazy with it and selecting 18-19ºc for the whole cabin (and flightdeck!) on a red-eye flight "because cold makes them not fall asleep". Jeez.

I'm a big supporter for pax comfort and try to do as many things as possible within reason to make an enjoyable experience for the pax. Certainly having the proper temperature aids in comfort and I gather that this "technique", so to speak, would be for a case of a somewhat prolonged turbulence. Don't know how other things, for example speed, would come into the equation as a slower speed can make a turbulence feel more "rhytmic" instead of plain bumpy. Perhaps a combination of various factors or methods can aid to counteract motion sickness.

I just recalled that many moons ago when I was a kid and used to travel by car with some family members, who are quite prone to get motion sickness, they used to lower the windows of the car whenever they started to feel it kick in. It did help them to a certain extent; I don't see a reason why it shouldn't work on an airplane too...

OOhhh, lovely :) Our bunch insist that we fly around with a minimum of 25 degs and often we'll be asked to turn it a bit more. It seems that Asians are cold blooded and anything below that temp they'll start to freeze. It's absolutely ridiculous when you're in the cabin, it's hotter than Hades and the cabin crew come around offering blankets. If you're at the back of the aircraft then you won't get offered a blanket because they've all been taken.

Hand-in-hand with that goes the number of requests for seats etc to be cleaned because of vomit. Believe me, more than I ever had in previous airlines where the absolute max was 23 degs.

I'm a firm believer that you can always put more clothes on, but there's only so much you can take off before the police turn up. Erring towards too cool a cabin would be my preference.

Obviously it will depend on the aircraft. Some aircraft the cabin temp. is controlled only from the flight deck but on larger aircraft each zone can be regulated by the cabin crew as well, within certain limits, defined by where the controls are set on the flight deck. From my experience it is possible to lower the cabin temperature significantly using the flight deck controls. Again, my experience only but I find hot, stuffy air round my face at any time is uncomfortable.

Pretty standard in a 737. The point at which the cc in the rear galley are complainng of the cold is right about when you have it perfectly set for the pax. Overheated 737s often seem to be a result of flight deck setting temps to suit occopants of the rear galley rather than the cabin.
