Natural therapy is the treatment method utilizing natural environments such asclimate, geographical features, hot springs and the blessings of nature. One of the naturaltherapies, climatherapy is conducted at the climatic stations where climate is deﬁned
according to their locations from the sea levels ; +) sea climate (thalassotherapy), ,)lowlands and the level ground climate (up to -** m above sea level), -) moderate mountainclimate (-**ῌ+,*** m) and .) high mountain (+,*** m-) climate. Especially, moderate andhigh mountain climate are well combined with walking, which is referred as “Terrainkur”
and applied to the patients from diabetes mellitus, obesity and to rehabilitation forischemic heart disease. In an addition, forest environment is pretty good for relaxation.
Just walking in a forest made more decrease in blood glucose levels in diabetic patients
than those obtained after cross-country ski race or treadmill walking. Balneotherapy isalso one of the natural therapies. It uses subterranean products, such as hot spring water,gases, mud, as well as climatic factors as therapeutical elements. This therapy isconducted by combination of hot spring water bathing, various thermo- and hydrotherapies, physical exercises, drinking, inhalation, etc., as the complex therapy. During .-weekbalneotherapy, blood glucose levels decreased with a circaseptan (about 1 days) rhythmical change without any oral medication or insulin administration. Moreover, stressrelieving e#ects by balneotherapy was observed. Natural therapy should be used more
widely to prevent diseases and for health promotion.
