Abstract Introduction The circadian timing system regulates diurnal sleep–wake rhythm. Previously, we showed that, in patients undergoing elective surgery, is altered and post‐operative sleep quality reduced. However, how the of surgical procedure affects disturbance what other factors affect this remain unknown. Methods Single‐centre prospective observational study investigating influence surgery on adult (≥18 years) surgery. Sleep–wake was measured from three nights before until seven after with a daily sleeping log. Primary outcome midpoint shift between morning afternoon surgeries. Secondary outcomes included affecting changes subjective quality. Results We 259 patients: 144 underwent procedures (08:00 h–12:00 h) 115 (12:00 h–17:00 h). Both groups had significant phase advance night when compared (mean − 00:41 h, 95% CI −00:27 h to −00:54 p < .001, for mean 00:28 −00:09 −00:46 = .003, surgery). there no between‐group difference 00:13 −00:35 h–00:09 .25). Reduction also similar. Phase larger an evening chronotype or lower pre‐operative Decline chronotype, longer better Conclusion Our results suggest that 08:00 17:00 does not modulate effect anaesthesia rhythm low risk delirium.
