I've got mild asthma, nowt so bad that I need an inhaler for, although I do need to stop and rest on hikes now and again for the tightness to go away, normally a couple of minutes does the trick.
Anyway, I found that I do better in winter without central heating. The shock of walking outside from a warm house really tightened the tubes, so one year when I was ultra skint, I just added layers rather than putting the heating on and I noticed that my chest wasn't tight any more going from inside to out.
When it's really cold, having a scarf that I can pull up and over my nose works very well.
It seems as if my breath warms the material and the dampness helps humidify the air coming in.
If you want to try life without central heating you need to turn it off
now. As the weather gets colder your body adapts, if you wait until proper winter to turn it off, you will be cold.
Kids adapt the best, their bodies don't seem to have our inbult preconceptions.
Another bonus of no central heating is the less likely hood of getting ill. I used to get at least three colds each winter but now, without central heating, I haven't had a single one for the past five years, not one cold.
Turned it off and feeling cold?
Put another layer on, remember thinner layers are better than one thick jumper.
Sometimes you get the shivers even with plenty of thin layers... take a hot bath
I tell you another thing, if you live in a terrace your neighbours will keep you warm, about 15deg's on the thermometer
