Being unable to sleep is an extremely serious problem. The agony of the time spent working to get to sleep during the middle of the night, a time when talking with others is not an option, is something that only the person experiencing it can understand. There are many different factors involved in difficulty sleeping, but a phenomenon seen often in students is "psychophysiological insomnia." Psychophysiological insomnia is a condition where some event or matter becomes the initial cause of sleeping difficulty, but the inability to sleep continues even after the issue has become resolved. For instance, when a very important job interview is coming up the following day, or the All-Japan Championships are approaching, or an important national exam will be held soon, everybody experiences nervousness and an inability to get to sleep. This difficulty sleeping is caused by excessive stress and is only temporary, and thus it does not require treatment. However, there are cases where even after the event or matter becomes resolved, the individual still remains anxious over whether or not he or she will be able to sleep. This condition is referred to as psychophysiological insomnia.

There are cases when general sleeping medication is used as treatment, but it's necessary to obtain a prescription from a qualified physician. People who suffer from this type of insomnia tend to gradually become fixated on sleep. There are also cases when they think to themselves, "Well, I didn't sleep well last night, so I'll sleep a little extra tonight," or they try to make up for a sleepless night with a nap. These strategies will not necessarily improve the sufferer's insomnia. We have listed some points of advice that will preserve a healthy sleep schedule as well as improve insomnia.
