What this trial studies
This is a pilot interventional program that asks emerging adults aged 19–22 to attend a 2-hour sauna session once per week for eight weeks, either alone or with a friend. Participants will complete weekly online surveys and receive text-message contact to track attendance and acceptability. The study focuses on feasibility outcomes: how acceptable the design is to participants and how well they adhere to weekly sauna visits and survey completion. Clinical outcomes such as changes in loneliness are explored in this formative phase to guide larger future trials.
Who should consider this trial
Good fit: English-speaking adults aged 19–22 with elevated loneliness who can provide consent and attend weekly in-person sauna visits in San Francisco are ideal candidates.
Not a fit: People who have heat intolerance, are pregnant or lactating, use nicotine regularly and cannot abstain, already engage in frequent social sauna practices, or cannot attend weekly sessions in San Francisco are unlikely to benefit.
Why it matters
Potential benefit: If successful, the program could reduce feelings of loneliness and increase social connection for participating emerging adults.
How similar studies have performed: Some research links sauna and other thermal therapies to improved mood and reduced depressive symptoms, but direct trials targeting loneliness in emerging adults are limited and this application is relatively novel.
