People of different ages sleep for different lengths of time and have different bedtimes and wake-up times. Generally, it is most appropriate to go to bed before 10-11 pm and get up at 6-7 am. The general population can sleep for 6-8 hours, and can decide to rest and wake up at different times according to their specific conditions. It is usually recommended to go to sleep before 11 p.m. because after 11 p.m. the organs of the body need to rest and detoxify, and if you do not sleep, it will affect the heart function, brain function, endocrine function, etc. A long stay up late can also easily lead to cardiac arrest, lack of energy, endocrine disorders, and even interference with immunity. For adolescent patients, it is necessary to extend the rest time appropriately. Long sleep at night is beneficial to the release of growth hormone, which helps the organism grow. Doctors suggest that you should try to go to bed early and get up early, avoid staying up late, develop a good work and rest schedule, have a good biological clock, and if you have poor sleep, you can take oral medication to improve sleep as prescribed by your doctor.
