Thermodynamic Exposure and Sleep in Military Cadets
This study is looking at how cold-water immersion, using a high heat sauna, or a combination of both might affect sleep and mood in military cadets. Researchers want to see if these activities can improve how well you sleep and your overall psychological health. They will use wearable devices like the Oura Ring to track sleep and other body information, along with questionnaires. You might be able to join if you are a military cadet at The Citadel, between 18 and 30 years old, and have a smartphone with the Oura Ring app. The study plans to enroll 45 participants, but its current recruitment status is unclear.
- Study design
- This is an interventional pilot study with 45 military cadets, who will be randomly assigned to one of three groups: cold-water immersion, high heat sauna, or a combination of both.
- What's involved
- You would participate in a 7-day baseline period, followed by 14 daily sessions of either cold-water immersion or high heat sauna, or both, depending on your assigned group.
- Compensation
- Not stated in the trial record.
- Follow-up
- Your sleep and mood will be assessed at the end of the baseline period (Day 7), after one week of intervention (Day 14), and at the end of the intervention phase (Day 28).

What this trial measures
- Sleep EfficiencyEach night of the baseline monitoring period (7days) and intervention phase (14days)
Percentage of sleep period spent asleep measured by the Oura Ring (percentage, %)
- Pittsburgh Sleep Quality IndexAt the end of the baseline monitoring phase (Day 7), end of intervention week 1 (Day 14), and end of intervention phase (Day 28)
Self-reported sleep quality
- Brief Mood Introspection ScaleAt the end of the baseline monitoring phase (Day 7), end of intervention week 1 (Day 14), and end of intervention phase (Day 28)
Self-reported assessment of mood consisting of 16 mood adjectives. Participants rate each adjective on a 4-point likert scale (1 = definitely don't feel, 4 = definitely feel). The scale uses a combination of direct and reverse scoring so that higher scores reflect more favorable mood states (max = 64).
