Finland and Russians spent a lot of time in saunas, looking at the death to recovery stats they fare a lot better than Iran, cold and dry now.
Bodys natural defence to the flu is to sweating and fever.
Cheap steam inhaling machine is almost a must have in times like this.
BS.
Once you have the virus inside the body, it's too late.
Moist air makes the virus fall to the ground faster, so it can't move around in the air.
The warmth is not responsible as much as the high UV radiation in summer, which damages the hull (shell) of any coronavirus. Inside the body it's 37 degree celsius, and the virus can replicate in this hot-moist environment. Above 40° it's over for the little bastard, but this is also critical for the human heart and brain. We're speaking body core temperature here, by the way.
Think twice.
If summers UV radiation won't help contain the virus by killing it, we're pretty fucked. Let's hope the best.
Emergency rooms are desinfected with robots carrying UV-C lamps. If temperature and humidity were the reason for the virus to die off, they would be decontaminated with hot steam. God, please think!
EDIT: The virus likes to spread indoors. Like the flu and many other respiratory pathogens. Indoors almost no UV-C radiation is present. T.h.i.n.k....
Yes it is very dry indoors with central heaters, or electric, some put moisturisers on the radiator to make air quality better.
