Is it okay to sleep 12 hours a day?
We often say that people need 7-9 hours of sleep, but some people require more sleep to feel rested. As adults, their nightly length of sleep tends to be 10 to 12 hours. This sleep is very normal and of a good quality. It is simply much longer than most people because of their natural biological clock.May 6, 2021
