Using sauna therapy to treat Long Covid symptoms

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This trial investigates the use of whole-body hyperthermia in a sauna-like environment as a potential treatment for Long Covid symptoms. It will enroll 21 participants who will be randomized into two groups experiencing different temperature conditions. The primary focus is on the feasibility and acceptability of the treatment, as well as its effect on reducing fatigue, a common symptom of Long Covid. Participants will be monitored for 4 to 6 weeks to assess the duration of any observed effects.

Why it matters

Who can join: the full rules

Inclusion Criteria:

1. 18-65 years of age
2. English language proficiency
3. Ability to provide informed consent
4. Ability to lie supine (on back) for 2 hours (required for sauna sessions)
5. Must have had clinically suspected COVID-19 and a positive antibody test or a documented SARS-CoV-2 infection (a positive reverse transcription polymerase chain reaction test) at least 12 weeks prior to Screening (Note: clinician judgment can override lack of positive COVID test with clear Long Covid onset and presentation)
6. The Patient Reported Outcome Measurement Information System Fatigue-Short Form v1.0 -Fatigue 7a (PROMIS F-SF43) raw score of 21 or greater at Screening (onset of fatigue confirmed post-infection as in other studies of PASC)
7. Individuals of childbearing potential must use an acceptable form of birth control.

Exclusion Criteria:

1. Fatigue for known reasons other than PASC (e.g. longstanding diagnosis of Chronic Fatigue Syndrome pre-dating Long Covid, low thyroid, multiple sclerosis, AIDS related fatigue, mononucleosis), as determined by clinical discretion of study investigators
2. Known hypersensitivity to infrared heat exposure, significant history of heat stroke
3. Breastfeeding, pregnancy or planned pregnancy during study
4. Active suicidal intent
5. History of bipolar disorder, psychotic disorders, eating disorders, obsessive compulsive disorder, and/or substance use or dependence (within the last year), as per the Mini-International Neuropsychiatric Interview (MINI)44
6. Positive urine toxicology screen for illicit drug use
7. Any serious unstable medical condition
8. Inability to fit into the sauna device. Morbid obesity (BMI \> 40) and/or body shape that might increase the risk of cutaneous burning from the device (because of skin being too close to the heat).
9. Back pain that would interfere with ability to lay on hard surface
10. Using medication that might impact thermoregulatory capacity and cannot be held for an appropriate length (at least one half-life) as determined by clinician judgment prior to receiving WBH treatment
11. Breast Implants
12. Claustrophobia that would interfere with ability to remain in sauna
13. Unsafe cardiac status as defined by abnormal ECG reading at screening visit or as determined by study doctor or subject's physician
14. History of or current diagnosis of thrombosis or thrombophilia
15. History of hemophilia
16. History of febrile seizures or seizure disorders
17. Any new treatments/medications for long-COVID that have started in the past 3 months
18. A subject who in the opinion of the Principal Investigator would not be able to safely complete the study or would jeopardize study integrity.
