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

  • Passing hot air through the nasal passage would not actually raise the temperature of the sinus membranes, throughout, to that temperature. So how does one raise the sinus temperatures to 133/56 without serious harm to the patient/subject? I mean, throw me in a 400 degree oven for an hour and you'll probably kill the virus.... – PoloHoleSet Mar 25 at 16:19

"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?"

No. None that I could find. Since the virus is systemic, including deep in the lungs, where it causes pneumonia as the most dangerous manifestation of COVID-19, I don't see how "heating the sinuses" could possibly work as a cure in general. Maybe as symptom relief... in the sinuses. (But that has been discussed here before.) Heating someone's lungs to 56C is probably extremely unsafe, if not outright lethal because

Temperatures above 49°C lead to irreversible cell damage as a result of protein denaturation. This thermal destruction process is markedly dependent on time.

So yeah, the usual joke about the treatment being successful, but the patient succumbing applies here.

As far as I know, the only cure candidates for COVID-19 that are seriously being tried (i.e. in genuine/non-crackpot medical settings) are antiviral drugs, after showing promising results in vitro. But even for antiviral drugs, there's the question whether:

Can the drug, which is given intravenously into the bloodstream, reach the cells it needs to clear the respiratory infection?

“We don’t know if the amount of remdesivir that’s going to get into the lungs is enough to get the virus down,” said Andre Kalil, an infectious disease specialist at University of Nebraska Medical Center and an investigator in the NIAID-sponsored trial. “This is part of the reason we’re doing the study.”

(Vaccines are also under development/trials, but that's not a cure if you have an illness already. Monoclonal (and even polyclonal) antibody therapy, which [roughly speaking] is the equivalent of a vaccine after you are sick already, is also being considered for COVID-19.)

  • Reading the original claim - I think it refers to breathing in air that is above 136 degrees, not raising the internal temperature, as this is commonly done in a sauna. – Mayo Mar 23 at 15:32

The linked video was taken down. While searching for an original link, it appears the original source is now (partially) disclaiming the efficacy of the treatment: https://future-world.com/mcatalog/stop-covid-19-now/

This doesn't answer the original question as asked so I will leave this question open in search of studies of the efficacy of using heat to treat COVID-19/general upper respiratory infections.
