Incident Record Concerning Fan Speed Bedtime
Subject adjusted fan speed after lying down, initiating a documented sequence now classified as standard procedure.
Incident Summary
At an unspecified hour prior to sleep, the subject entered a lying-down position and immediately identified the fan speed as incorrect. The fan had been running at this speed for the preceding forty minutes without complaint. The lying-down position changed the assessment.
Subject adjusted fan speed. Sleep resumed approximately eleven minutes later, following a brief period of re-evaluation.
Timeline
Prior to incident: Fan operating at speed set during waking hours. No objections recorded.
Incident onset: Subject achieves horizontal position. Fan speed, previously acceptable, becomes the primary environmental concern.
Response phase: Speed adjustment performed. A second adjustment occurred six minutes later. Speed was returned to a value close to the original.
Resolution: Subject determined that the first speed was correct after all. This determination was not available at the time of the first adjustment.
Contributing Factors
People change fan speed after lying down because body temperature seems to use a different standard in bed. This standard has not been calibrated against any external measure. The standard is proprietary.
The first accommodation for fan speed bedtime looks harmless and removes a little uncertainty. The accommodation becomes teachable over time, so newcomers in shared sleeping arrangements learn the protocol without anyone naming it.
The ritual is intended to make sleep easier, yet it gives wakefulness one more detail to manage. This is a known outcome. It has not changed the behavior.
Classification
Under the governing rule, fan speed bedtime is considered stable once removing it would require an explicit conversation. No such conversation has been initiated. The incident is therefore not classified as an incident.
It is classified as procedure.
Actions Required
None. No one may correct fan speed bedtime unless they are willing to own the replacement procedure. No one has volunteered.
Later, ignoring fan speed bedtime appears reckless even though the rule was invented from habit. This finding is noted for the record.
