At the end of the nineteenth century, there was quite a craze for deep breathing exercises as the remedy for many ills. It was also suggested that,if done properly, these exercises could help keep the body warm.
On the 28th February 1888, the Dundee Evening Telegraph advised, "Throw the shoulders well back, and hold the head well up. inflate the lungs slowly, the air entering entirely through the nose. When the lungs are completely filled, hold the breath for ten seconds or longer and then expire it quickly through the mouth. After repeating this exercise whilst one is chilly, a feeling of warmth will be felt over the entire body, and even in the feet and hands. It is important to repeat this exercise several times a day and especially when in the open air. Don't forget."
