sea air
In 1753, Dr. Richard Russell popularized the idea that sea air was beneficial to one's health and nervous system in his writing A Dissertation Concerning the Use of Sea-Water in Diseases of the Glands. By the 19th century, it was generally accepted that the air, in addition to the actual water, had health benefits, but this belief was not backed by science.
