With the subs, the air blowing on your face at all times from the portholes is supposed to help claustrophia.
I tried that trick when we lived in a dinky converted garage on a Wyoming llama ranch one summer. The sleeping space had a ceiling so low that it was maybe four inches from the end of your nose. Impossible to sleep from that clawing, closed in, heart-pounding feeling.
I dragged in a fan and aimed it on us. It did help to have a constant flow of air.
