Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Abrupt changes to one's lifestyle disrupt biorhythms. Acute effects are well known from jet lag where transmeridian travel leads to insomnia, fatigue, irritability, gastrointestinal symptoms and other complaints. Several studies in the hospital environment reported dampened and misaligned biorhythms, suggesting that the inpatient experience is replete with circadian disruptors. However, comprehensive assessments of how circadian clocks are affected in intensive care and how this predicts post-operative recovery and risk are largely missing.
