Modern Shower

Basically a Scottish shower consists in alternating application of hot and cold water during a shower session. In the most reduced form, it may consist only of one alternation, that is, applying cold water after a usual hot water shower. It is thought that the alternation of heat and cold improves blood circulation, that is beneficial for instance in rheumatic disorders. The application of cold after heat is well documented in the sauna article paragraph Health risks and benefits/with cold exposure.
Installation
Installation of a shower requires several water transportation pipes. These include the pipe for hot water, cold water, and the drainage pipe.
