It is usually healthy to sleep for 7 hours every day, but due to different personal conditions and physical qualities, everyone's sleep time is different. Some people sleep for a short time, usually 7 hours' rest can meet the body's demand for sleep, but it is best for young people to meet 8 hours' sleep, usually from 22: 00 to 6: 00, which is more suitable for the human body. Reasonable sleep time is also beneficial to their own health and better liver.
If you feel that you don't have enough sleep, you should take more rest, try to avoid staying up late, keep your work and rest habits regular, and you need to do some physical exercise to strengthen your physique, avoid eating spicy food and eat more fresh fruits and vegetables.
