The time to go to bed at night should depend on the age group, with children recommended to go to bed at 8-9 pm and teenagers and adults recommended to go to bed at 10-11 pm. It is impossible to generalize the best time to go to sleep at night for different age groups. Children are in the growth stage and need to sleep for 8-10 hours a day, so it is recommended to go to sleep around 8-9 pm every night. Sleeping before 9 pm helps to release growth hormone and promote children’s growth and development. 11pm to 3am is the prime time for sleep, adolescents should not sleep less than 8 hours a day, while adults should maintain 6-8 hours of sleep a day. Therefore, for adults, if you go to bed at 10 pm, you will have entered the deep sleep period at 11 pm, and your body is in the liver detoxification stage, so teenagers or adults should try to fall asleep before 10 pm. In daily life, we need to pay attention to the combination of work and rest, and we can use hot water to soak our feet before going to bed to help improve the quality of sleep.
