Field Notes on Bedtime Water Calculation

FIELD NOTES: BEDTIME WATER CALCULATION Observation Date: Most nights Subject: The person who is neither asleep nor getting water

22:43

Lights off. Position established. Eyes closed. This is a stable configuration and represents a promising start.

22:47

Thirst noted. Not acute. A presence, rather than a demand. The person does not get up.

22:47 to 22:53

The calculation phase. The subject is observed to be performing, without visible activity, the following analysis: if water is consumed now, sleep onset will be delayed by the time required to retrieve the water, drink it, and return to position. Furthermore, water consumed at this hour has a probability of requiring a bathroom visit at approximately 2 AM to 4 AM, which would constitute a second interruption.

Against this: thirst is currently rated a 3 out of 10. At what point does thirst become a 6 out of 10, which is the threshold at which sleep is impacted by the thirst rather than by the retrieval of water for the thirst?

The calculation is not about water. It is about how much wakefulness can be created by addressing thirst versus how much can be created by not addressing it.

22:53

Subject does not get up.

23:11

Subject is still awake. Thirst is now estimated at 4 out of 10. The calculation runs again. It reaches the same conclusion. The glass is close enough to be accessible and far enough to require getting up, which is the exact design that created the problem.

23:19

Water retrieved. Consumed. Return to position.

Observation

Bedtime water calculation has acquired standing. It is present every night that thirst is present. The calculation always runs. The outcome varies. The running of the calculation is the invariant.

Nobody installed this behavior. It arrived with the combination of a glass of water, a bed, and a person who would have to get up to reach one of them. The procedure for the next similar night begins the moment the first instance resolved.
