Heat therapy: a new hope for long COVID sufferers?
NCT ID NCT06928116
First seen Jun 27, 2026 · Last updated Jul 17, 2026 · Updated 1 time
Summary
This study tests whether at-home lower-body heat therapy can help older adults (ages 50-90) with long COVID improve their walking ability and overall physical function. Participants will use heat therapy at home, and researchers will measure changes in walking distance, physical performance, and blood vessel health. The goal is to find a safe, easy option for those who struggle with exercise.
