I've long suffered with dry skin and sore throats. I never knew but these are usually caused by low humidity. Using a humidifier in the winter and on chilly nights helps quite a bit. I found this really cool site that gives a lot of useful information and advice on whole house humidifiers as well as single room.
I didn't know there were different types of humidifiers, http://www.humidifierinformation.com/different-types-compared.php. Nor did I know that
there were so many features, http://www.humidifierinformation.com/desirable-features.php. There is also a lot to learn about the perfect humidity level, http://www.humidifierinformation.com/optimum-humidity-levels.php.
Check out this site and learn how you can stop having to deal with cracked lips, itchy eyes and even sinus headaches, along with dry skin and sore throats.
