Trash sleep vs good sleep

• Falls asleep while watching TV or listening to music.
• Force yourself to go to sleep and wake up to the "point", but the "point" is always changing.
• After waking up naturally, forcibly extend the sleep time.
• Do not sleep at night, rely on daytime or weekends to make up for sleep.

The scale of good sleep

• Able to fall asleep within 10-20 minutes, and the time to fall asleep for a long time is less than 10 minutes (long-term sleep time longer than 30 minutes is insomnia).
• Not waking up on a good scale or waking up occasionally (e.g. to urinate), but quickly falling asleep within 5 minutes until the next morning
• No startled dreams during nighttime sleep, and soon after waking up from dreams, they are forgotten.
• After waking up in the morning, you will be full of energy, relaxed and happy, without fatigue, and with high work efficiency.
