2./kloc-For adults aged 0/8 to 64, it is better to sleep for seven to nine hours a day, or only six or ten hours a day, but the specific time period varies from person to person.
People over the age of 3.65 are generally advised to sleep for about seven or eight hours, but some elderly people get up early in the morning and only sleep for about five hours a day. How long you should sleep depends on your state after sleep. If you only sleep five hours a day and you are still full of energy the next day, it means that your body can sleep five hours.
