What time is golden sleep?

The length of sleep required varies by age. For most adults, it takes six to eight hours to get enough sleep. Older people sleep less, perhaps five to seven hours, while children need more sleep, perhaps eight to ten hours. Infants need more sleep. For most adults, it is more scientific to go to bed at 10 p.m., sleep time can be from 10 p.m. to 6 a.m., the elderly can go to bed earlier, some can go to bed at 9 p.m., and children may go to bed earlier, can go to bed at 8 p.m. to 9 p.m. This is more scientific, it is best not to fall asleep after midnight.
