I find these comments to be surprising.

I've just assumed that it was understood that too low humidity has the  
effect of drying out the protective mucous layer on our nasal membranes  
making them and us more susceptible to cold and flu viruses, not to  
mention the "crusty nose" syndrome, dry itchy skin, dandruff etc.

Further, lower humidity has the effect of increasing the rate of  
transpiration from our bodies so that at the same temperature, some people  
may feel colder.

These are experiential observations rather than conclusions based on  
peer-reviewed scientific research.

Me ? I like the feel of 45-60% interior RH in winter, which I don't find  
at all surprising given that our bodies are roughly that percentage water.

As Forrest Gump would say "Stupid is as stupid does" ... or something like  
that.
