Sleep Normalization
Sleep disturbance is one of the most persistent and clinically significant challenges in early recovery [25].
Sauna and contrast therapy improve:
• Depth of sleep [23,24]
• Time to sleep onset [23]
• REM and slow-wave sleep percentages [23]
• Nighttime anxiety and restlessness [25]
Better sleep → improved mood → better engagement → stronger outcomes.
