Q: This is my first time in the USA during winters. The heater is switched on the entire day at home. I also make it a point to switch on the humidifier. However, it is a bit difficult for me to breathe. Do let me know is it a matter of concern and what should I do?

A:The use of humidifier should help. If despite that there is dryness in nose, you can instill saline nasal drops a couple of times and adequately hydrate yourself by taking sips of water at intervals.
