Many people these days underestimate the importance of a good night rest. There is a large portion of population that sleeps at irregular hours. Sometimes, we also tend to sleep only a few hours per day. We might not realize that if we neglect sleep then there are going to be consequences. We should try to sleep to least 8 hours per day on a comfortable bed. I heard that guests sometimes like to sleep on guest air beds. You should also keep in mind that it is important at what hour you go asleep. Generally, most people benefit the most from sleeping if they go to sleep before midnight. Even if a person sleeps 8 hours, but goes to asleep at a very late hour, then he might still be tired. Keep in mind that sleep deprivation causes fatigue, learning and concentration difficulties. It can also cause accidents. That is why never underestimate the important of a good night sleep.
