Hygiene

Unclean skin favors the development of pathogenic organisms – the dead cells that continually
slough off of the epidermis mix with the secretions of the sweat and sebaceous glands and the
dust found on the skin to form a filthy layer on its surface. If not washed away, the slurry
of sweat and sebaceous secretions mixed with dirt and dead skin is decomposed by bacterial
flora, producing a foul smell. Functions of the skin are disturbed when it is excessively
dirty; it becomes more easily damaged, the release of antibacterial compounds decreases,
and dirty skin is more prone to develop infections. Cosmetics should be used carefully because
these may cause allergic reactions. Each season requires suitable clothing in order to facilitate
the evaporation of the sweat. Sunlight, water and air play an important role in keeping the skin healthy.
