There is a reason for being energetic. Some people are born with less sleep time, so sleeping only 6 hours a day can ensure energy. On the other hand, sleep quality also affects a person's sleep effect. Everyone needs different sleep time, and the sleep time needed at each stage is also different. Usually, the elderly need less sleep time every day. If you can fall asleep quickly when you sleep, and can ensure a deep sleep, then naturally you can make your sleep quality higher. Even if you don't sleep that long, you can still be full of motivation, but if you sleep, it's hard for you to enter a state of deep sleep, and it's always easy to wake up, so no matter how long you sleep, you will feel more sleepy. So those who are energetic and don't need much sleep time have a very high quality of sleep, and these people can better enter the state when they sleep.
