Recognizing the amount of sleep our body needs is an important part of managing insomnia. Many, but not all, insomnia sufferers have trouble falling asleep at bedtime.
There can be several reasons for this type of problem. One possibility is that the sufferer is overestimating how much sleep his or her body needs. For example, let’s say your body needs seven hours’ sleep, but you think it needs eight. Every morning your alarm goes off at 7:00. Every night you try to fall asleep at 11:00. In this case, your efforts to fall asleep at night may fail for an hour. (Alternatively, you might fall asleep with out any trouble, but wake up an hour “early” each day.) This is sometimes misinterpreted as insomnia, when really it is better understood as misjudging your body’s needs. Some people think that everyone needs eight hours of sleep per night, but in reality there is variability in how much sleep our bodies need.
