Ok anybody use a sauna as have an interesting read.

Is Sauna Temperature Enough to Kill Coronavirus?
Coronaviruses (MERS-CoV) died when under environmental circumstances of 56 degrees Celsius (132 degrees F) for 25 minutes. Increasing the temperature to 65 degrees Celsius (149 degrees F) was even better and only one minute was needed to kill viruses. No killing was observed after 2 hours at 25 degrees Celsius (77 degrees F).
The dried virus on smooth surfaces retained viability for over 5 days at temperatures of 22-25 degrees Celsius (72-77 degrees F) and relative humidity of 40-50%, typical of air-conditioned environments. However, viruses died quickly at higher temperatures and higher relative humidity (38 degrees Celsius – 100 degrees F – and relative humidity greater than 95%). This explains why Malaysia, Indonesia or Thailand with high temperature and high relative humidity environments do not have major community outbreaks of SARS.
At a relative humidity of 75%, infectivity of the coronavirus was very sensitive to temperature, decreasing two orders of magnitude between 19 and 25 degrees Celsius (77 degrees F).
At 4 degrees Celsius (39 degrees F), coronaviruses live up to 28 days but they can be inactivated at low levels of 20% relative humidity. The inactivation was more rapid at 20 degrees Celsius (68 degrees F) at all humidity levels. The viruses were inactivated more rapidly at 40 degrees Celsius (104 degrees F) than at 20 degrees Celsius. When high numbers of viruses are deposited on surfaces, coronaviruses causing both GI symptoms and respiratory symptoms may survive for days on surfaces.
SARS-coronaviruses may be shed into the environment and transferred from environmental surfaces to hands of patients and healthcare providers. Once contaminated, hands can then initiate self-inoculation of mucous membrane of the nose, eyes, or mouth.
Coronavirus infectivity was completely lost after 14 days of incubation at 22 degrees Celsius (72 degrees F), 33 degrees Celsius (91.4 degrees F), or 37 degrees Celsius (98.6 degrees F) but remained constant at 4 degrees Celsius (39.2 degrees F) for the same length of time.
SARS coronavirus is inactivated at 56 degrees Celsius (132.8 degrees F), reducing the titer to below detection.
Based on these points alone, a sauna does seem like it would be hot enough to kill the coronavirus. Traditional saunas are generally in the range of 150-175 degrees F. Infrared saunas use a lower temperature of 120-140 degrees F. These temperatures will kill coronaviruses.
Thus, if an infected person with coronavirus went into your sauna, you could kill the virus by the heat.
If you have been exposed to coronavirus, no doubt the virus is on your skin. It could be killed by the temperatures in the sauna. The more virus particles you kill, the quicker your recovery because the virus isn’t reproducing.
However, if the virus has infected your lungs, it’s unlikely the sauna will help treat the virus. By the time the hot air reaches your lungs, it is much cooler. Surely, it’s warmer than normal and might help, but it’s unlikely to cure the virus in one sitting.
There are additional benefits to regular sauna use that will promote good health and could offer additional defense against sickness. "
