The low humidity and heated air being very dry I do tend to have dry itchy skin. I learned from Deepak Chopra what to do for it. Here is a link from long ago about the full body oil rub.

Normally I rub the oil on and 10 minutes later take a shower. Here is a link for a better method if you are not in a hurry. Very relaxing and feels ooohhh sssooooo good!

If interested, there is a lot more around the net about the oil rub. Google search: https://www.google.com/webhp?sourceid=navclient&ie=UTF-8&rlz=1T4GGNI_enUS554#q=sesame+oil+body+rub+deepak+chopra
Good luck and for what it is worth, just got through rubbing with sunflower oil, leaving on 10 minutes and showered. Oh my do I feel great!!!!
