A property's sleep environment, measured.
Most hotels invest heavily in the visual experience of a room. Light, sound, scent, texture, and temperature often receive less attention, despite being the primary drivers of whether a guest sleeps well.
The Z Lab Sleep Audit is a structured assessment of that environment, measured against specific thresholds and shaped by circadian research.
Each property is assessed across three pillars. Every criterion within each pillar is measured against specific, science-backed thresholds.
Temperature, lighting, blackout capability, noise isolation, and bed quality. The physical conditions that determine whether the brain can initiate and sustain sleep.
What a property provides for the night. From sleep accessories to considered treatments, rituals, and in-room programmes that help a guest prepare for rest.
The team's ability to guide guests on sleep. Awareness of the psychological factors that influence rest, and the confidence to turn that knowledge into conversation.
