This might suggest that if you are a vocal overdoer, that it might make your apnea worse. (suggesting that if you are straining your voice a lot, it might make your apnea worse.) Additionally, if you are a heavy smoker, you might also be making your apnea worse.
Link HereThe vocal folds are two folds of tissue narrowing the windpipe that can open widely for breathing and close for speaking and singing. These folds are covered with a tissue that is similar to the moist lining on the inside of the lip. When you speak the vocal folds move together in order to vibrate, but it is actually the lining that does most of the vibrating. The actual vocal ligament itself moves much less. This lining is designed to vibrate many times per day, but it does have limits. At some point, with extensive use, the vocal fold lining suffers much the same way that the skin of you hands suffers if you have to dig ditches all day with a shovel. The lining swells and may thicken with continued use. Like skin, if you rest your vocal folds, the acute swelling may resolve. More chronic swelling may not completely resolve.
This link shows swelling as a result of smoking as the cause of swelling.
