This may not be the right forum for this question, but I almost always experience temporary nausea when entering the cabin of a larger passenger plane (e.g. A320). It hits me as soon as I enter the cabin and can be quite debilitating. Strangely enough it tends to dissipate almost completely after about 5 minutes inside the cabin.
Does anyone know what might be causing this? My only thought is that is has to do with the air inside the cabin as even the smell of the cabin when boarding (but still on the boarding ramp) causes the nausea to occur.
Additionally, I'm open to any suggestions for how to reduce this effect... I fly quite often and have learned to put it up with this sensation but I would greatly appreciate not having to go through this anymore.
