Depending on your age, 8 hours might not be enough to keep you from feeling sleep deprived. That feeling you have when you haven’t gotten enough rest. The desire to just lay down and close your eyes. The constant need to yawn. Or that overall “fuzzy” feeling when you just can’t seem to focus. But if 8 hours is the recommended time that an adult sleeps, why is 8 hours sometimes not enough? It’s more than the amount of sleep that we are getting, but the quality of sleep that is important.
Quality of sleep matters. Personally, I lay in bed for 8 hours each night, but I am not sleeping for that duration. First is the time it takes me to fall asleep. Then there are the times during the night that I wake from my sleep, such as when I need to use the restroom or if something else has woken me. Another factor to take into account is the type of sleep I am getting.
