Air Conditioning Sickness

🔊This unit's early lessons described cold as one of the six excesses, an external factor traditionally understood to enter the body and disrupt its normal warmth. Air conditioning sickness is a modern label for an old pattern applied to a distinctly modern setting: prolonged exposure to artificially cooled air, especially after the body has been overheated, is described using the same cold-excess framework used for any other cold exposure, rather than treated as a separate, unrelated modern ailment.

🔊The traditional reasoning follows a specific sequence: a body that has just been sweating in the heat has its pores open, in a state traditionally described as more vulnerable to invasion precisely because the usual protective barrier is relaxed. Stepping directly into strongly air-conditioned air at that moment is traditionally read as inviting cold to enter through those open pores far more easily than it would through a body that had time to cool down gradually and close them again first.

🔊This is one more instance of a broader principle repeated throughout this unit: the six excesses were never meant to describe only naturally occurring weather. A modern room cooled well past outdoor temperature is, from this framework's perspective, simply another source of the same cold excess a sudden winter chill would produce — which is why the traditional advice attached to this pattern is unusually simple and unusually modern-sounding at the same time: let the body cool down gradually and let the pores close before stepping into strong air conditioning, rather than moving from one extreme straight into the other.
