I thought that a dry environment - outside was safer for me - in that the viruses are carried in droplets of water in the damp uk winter air.
Though then I read that if you have central heating you should have a bowl of water underneath to put moisture back in to the air. I realise that this is indoors where you have some control over the people you come into contact with. Why is moisture in the air good?
I read in the British Lung Function magazine this morning that the dry cold air as found on the Continent (Seasonal Shopping article) is especially bad for some lung conditions. Then also that the moisture droplets get bigger when the weather is colder and that this can cause more problems.
Apologies to anyone trying to fathom out what I am on about. Basically I just want to avoid going out - when possible - in the worst type of weather for my asthma and especially the type of weather when viruses are more able to survive and get inside my lungs.
