The following video is quickly making rounds via social media.
The video claims Dr. Dan Lee Dimke has found that raising the temperature of the sinuses to 56°C (133°F) for 15 minutes is an effective cure for upper respiratory viruses, specifically SARS-CoV-2, the virus causing COVID-19. Several methods for achieving this provided in the video are (1) a hot desert (simple, but not accessible to general world populations), (2) a sauna (more accessible), and (3) using a hair dryer (more accessible than a sauna to many, but more complicated to perform).
Because the WHO, CDC, and general media have not yet advocated this solution. Are there any peer reviewed studies regarding the efficacy of heating the sinuses as a treatment for COVID-19, or more generally upper respiratory diseases?
I found this review from this answer, but that review is limited to treating symptoms, not the actual cause of respiratory infection. The review is also legitimately questioned in the answer's comments
