Steam inhalation — as it’s called — isn’t exactly some new solution to clean out the body’s airways. There are loads of benefits for both children and adults, especially the sick. For those with bronchial and sinus infections, allergies (especially related to foreign substances), and even the plain old common cold: Breathing in moist, hot air is an excellent aid. On top of this, singers know that dry vocal cords are the bane of any voice. Steam inhalation makes the vocal cords more flexible, less irritated, and reduces overall swelling. In short, if you don’t have your own personal sauna, the next best thing is to hold your face over a steaming bowl of hot water and put a towel over your head to trap in the steam.
On the Paul McCartney website, McCartney says that he learned about the benefits of steam inhalation way back when The Beatles first hit Hamburg, Germany in the 1960s. Acclaimed singer and pianist Little Richard used to do it before going on stage, and we all know how easily he hit high notes. Specifically, McCartney does his mini-steam bath an hour before going on stage, and then does that classic, mom’s solution for cleansing the throat: He gargles with salt water.
As a side note, McCartney said in the Q&A that he also tackles stage fright by checking to see how quickly his shows sell out. If tickets sell faster it “gives you a confidence and I think I can probably relax, they probably like me.”
