Good morning, why does my voice sound lower when I wake up?

Have you ever noticed that your voice often sounds lower and hoarser right after waking up? It's actually completely normal. While you sleep, your vocal cords aren't used for a long time, and breathing overnight can make your throat drier. There might also be some slight swelling around the vocal cords. Therefore, when you first wake up, the vibration state of your vocal cords is different from usual, which can make your voice sound lower. Usually, after drinking some water and speaking a few words to let your body slowly wake up, your voice will gradually return to normal. So, if your first words in the morning sound particularly low, there's no need to question your life.
