This study is testing if a treatment called water-filtered whole-body hyperthermia (WBH) can help people with post-COVID syndrome, which often causes tiredness and affects daily life. WBH involves gently heating the body with special light, while giving 10 liters per minute of oxygen. The study lasts 2 weeks with 2 sessions each week, plus a 3-month follow-up. Around 60 people, split into two groups, will join. One group will get a gentle version of WBH; the other gets a mild form.
Researchers will check blood before, during, and after treatments to look at immune and inflammation markers. Participants will also answer questions and keep a diary about sleep, energy, and pain levels for 15 weeks. Interviews will be done with some participants by phone after treatments to learn more about their experiences.
- Study duration: 2 weeks of treatment and a 3-month follow-up.
- You need to be 18-75 years old and have a confirmed post-COVID diagnosis.
- Participants will document their daily activities and symptoms.
