it's totally related to humidity.
The air inside has the same dew point as the air outside. If
the air outside is at 45degF and it's saturated (100%
humidity, ie it's raining) and you bring that air inside and
warm it to 70degF, it will now have a relative humidity of
<5% - ie about the humidity you have in a desert and
in forests, has all the firefighters on alert.
If you have synthetic blankets, after you turn the lights
out, rub the blankets vigorously together - you'll see
flashes of light.
My skin starts coming out in a rash each winter (about Nov,
when the weather changes), and my lips crack.
It seems most people don't do well in really low humidity
It would be nice if work places maintained a reasonable
humidity in winter but they don't. Philip Greenspun (find
with google) recommends it for good productivity in winter.
The cure is humidity - move to Florida or Galveston. If
you're staying here, you can make your house safe if you run
a humidifier about 1/2gal/day in a normal sized house (used
distilled, not filtered water, otherwise you'll be injecting
nano-sized particles of silica into the air - and your
lungs). It keeps my skin under control, and stops the
blankets from lighting up.
After you step out of the car, hold the key and touch it
against the metal of the door before you press the lock. As
for computers, I touch a metal part of the case (not just
the paint) before I insert or remove cables, zip disks,
