A deeper voice in the morning is an inevitable result of a good night’s rest. During sleep, the tissues in our throat collect fluid, which is also what causes our eyes to look puffy when we just wake up. Our lack of vocal cord use during the night also causes mucus to build up during the hours we spend asleep.
