'Sleepiness' is a word that describes the feeling of being tired and wanting to rest or sleep. You might feel sleepiness when you haven't had enough sleep or when you've been doing an activity that makes you feel tired, like exercising or working. It's important to pay attention to your sleepiness because it can affect your ability to focus and think clearly. If you're feeling very sleepiness, it's a good idea to take a nap or get some rest so you can feel more alert and energized.
