About this trial

This pilot study investigates the effects of cold-water immersion, traditional sauna use, and their combination on sleep architecture and psychological health in military cadets. The study uses wearable technologies including the Oura Ring to collect objective sleep and physiological data.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

None

Disqualifiers

Medical contraindications to continuous wearing of the Oura Ring.

Current diagnosis of neurological conditions that impact vascular blood flow or the individual's ability to regulate temperature.

History of cardio-vascular conditions or history of poor blood circulation.

History of heat stroke or known sensitivity to hot/cold environments.

Trial outcomes

Primary outcomes

1

Sleep Efficiency

Percentage of sleep period spent asleep measured by the Oura Ring (percentage, %)

Time frame
Each night of the baseline monitoring period (7days) and intervention phase (14days)
2

Pittsburgh Sleep Quality Index

Self-reported sleep quality

Time frame
At the end of the baseline monitoring phase (Day 7), end of intervention week 1 (Day 14), and end of intervention phase (Day 28)
3

Brief Mood Introspection Scale

Self-reported assessment of mood consisting of 16 mood adjectives. Participants rate each adjective on a 4-point likert scale (0 = definitely don't feel, 3 = definitely feel). The assessment captures 2 core dimensions of mood valence (pleasant v. unpleasant) and arousal (active v. calm).

Time frame
At the end of the baseline monitoring phase (Day 7), end of intervention week 1 (Day 14), and end of intervention phase (Day 28)

Secondary outcomes

1

Total Sleep Duration

Total duration of sleep period measured by the Oura Ring (seconds, s)

Time frame
Each night of the baseline monitoring period (7days) and intervention phase (14days)
2

REM Sleep Duration

Duration of sleep period spent in REM sleep measured by the Oura Ring (seconds, s)

Time frame
Each night of the baseline monitoring period (7days) and intervention phase (14days)
3

Deep Sleep Duration

Duration of sleep periods spent in deep (N3) sleep (seconds, s)

Time frame
Each night of the baseline monitoring period (7days) and intervention phase (14days)
4

Light Sleep Duration

Duration of sleep period spent in light (N1 or N2) sleep (seconds, s)

Time frame
Each night of the baseline monitoring period (7days) and intervention phase (14days)
