Definition
Sleep artefacts are external props and routines — mask, earplugs, temperature, supplements, weighted cover — that protect sleep continuity when chosen deliberately.
Origin
Sleep hygiene traditions accumulate tools that reduce sensory interruption and stabilise the sleep window. Performance operators treat them as engineering, not superstition — and test dependence like any other stack.
Mechanism
Artefacts lower arousal and sensory leak so sleep onset and continuity improve. The failure mode is identity fusion: “I cannot sleep without X.” Mastery is using the kit for elite recovery and training nights with a thinner kit (Master of Opposites).
Applications
- Keep artefacts for high-load weeks; schedule one thinner night.
- Treat glycine, mask, earplugs as variables in a journal — not permanent law.
- Protect the sleep floor before chasing focus millimetres.
