NCT ID NCT07201935
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tests whether cold-water immersion, sauna use, or a combination of both can improve sleep quality in 45 military cadets. Participants will do 14 daily sessions of one of the therapies while wearing an Oura Ring to track sleep. The goal is to see if these temperature-based treatments can boost sleep efficiency and mood.
