Primary Outcome Measures

Name	Time	Method
<p>To determine the quality, quantity and distribution of sleep in healthy<br /><br>subjects in different environments.<br /><br><br /><br>Sleep-related parameters (using EEG: Rechtschaffen & Kales (R&K) manual scoring)<br /><br>• Number of arousals (and awakenings) per hour<br /><br>• Total sleep time (any sleep stage other than awake, derived from EEG)<br /><br>• Sleep efficiency<br /><br>• Sleep continuity </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>To investigate the correlation between stressors present in the ICU environment<br /><br>and continuity of sleep, in healthy subjects.<br /><br><br /><br>Percentage of arousals caused by sound<br /><br>• Correlation between sleep continuity and environmental parameters<br /><br><br /><br>Environmental parameters:<br /><br>• Sound levels (decibel and amplitude of spectral components)<br /><br>• Reverberation time<br /><br>• Light levels (Lux)<br /><br>• Light frequencies<br /><br>• Temperature (degrees Celsius</p><br>
