Does rubbing one's hands disinfects or sterilizes?

At your own risk, this is not a medical advice.


Does rubbing hands (Karate Kid style) disinfects or sterilizes due to the high local temperature? Is the peak temperature very high?


Is the local temperature created very high as one can smell an almost burned odor at the palms? This is happening even after rubbing hands for a few seconds.


Does rubbing also get rid of dead cells together with dirt?


Is this related to the recommendation by medical doctor Giangos Karavis in his book of performing daily air bath, sun bath, rubbing the bodyskin with a clean dry towel or hands for general well being?


Is another method of cleaning hands using sea water due to salt and iodine?
