We in the sauna community are trying to digest the interesting report from Dr. Rogert Seheult, MD. (Thanks Jeff P., Sara, and Mike, and a few others for passing this along).
Many of us have been taking saunas for decades, and few of us have suffered from major colds or flus. But this is anecdotal, and not clinical. Dr. Seheult, in this video below, takes us through well researched studies and analysis of how hot/cold therapy may boost immunity – and fight off the effects of Covid-19.
You can skip to around the 2:00 mark to learn more about the immune system. The immune system is like our country’s Armed Forces. There are a lot of threats that can affect the human body. And the body fights back in multiple ways.
The virus is able to “down regulate” our immune system. When our innate immune response is a critical factor in disease outcome.
Monocytes (part of the innate immune system) and “Natural Killer Cells.” – two terms we may need to learn more about.
Suppressed innate immune response is what is making people sick.
Thermal infected fever monocytes. A thermal effect of fever directly activates monocytes.
Immune changes of humans during cold exposure effects of prior heating and exercise. 1990
Dr. Seheult “heat can improve the immune system, then subjecting to cold can actually enhance the immune system, especially the innate immune system which .. that’s the portion that is effected with Covid-19. exposure to cold.”
Statistical increase in white blood cell count.
Thermal stress dampens analogous to a natural fever.
Check out Dr. Seheult’s chart of current Nordic Countries Covid-19 reported affects:
And if this isn’t enough, he brings Japan into the mix, a country where thermic bathing is also very popular. Causation or correlation? Not sure, but it gets one thinkin’, especially as:
Fever can actually reduce the cytokine storm and improve the innate immune system.
The Austrian study: in six month time, there was significantly fewer colds with the sauna group. Regular sauna bathing probably reduces the common cold.
