Kanpu masatsu (乾布摩擦, literally ''dry towel friction'') is a Japanese custom where one rubs a dry towel along the body to create warmth and friction, particularly in cold weather, to promote good health or ward off disease. Although it physically remembles a vigorous sponge bath, kanpu masatsu is not a form of bathing as its goal is to warm the skin by friction and not to cleanse or wipe the body. Kanpu masatsu is often practiced in a group environment, particularly among children in schools where it is sometimes part of a morning exercise routine. Popularly imagined to prevent disease, especially colds and flu, like many folk beliefs its effectiveness is unclear, though there is some evidence it may be mildly helpful. A 2012 study of 24 males at the Department of Immunology, Niigata University School of Medicine found changes in lymphocyte and granulocyte levels versus a control group and concluded that kanpu masatsu is a "''mild aerobic, systemic exercise that might affect the immune system via the autonomic nervous system.''" 〔Acton, Q. Ashton. Issues in Biomedical Engineering Research and Application: 2013 Edition. ScholarlyEditions, 2013, p. 1005.〕 A 2002 study at Central Aizu General Hospital of bedridden elderly patients reported possibly beneficial results, concluding "''This technique may be used to reduce a variety of complications caused by the decreased immunity observed in bedridden old patients.''"〔Pubmed. http://www.ncbi.nlm.nih.gov/pubmed/12218940〕 ==See also== *Culture of Japan *Massage therapy *Radio calisthenics 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kanpu masatsu」の詳細全文を読む スポンサード リンク
