ABSTRACT
What causes sleeplessness? Most people have problems sleeping from time to time. Our sleep problems often start after an upsetting life event, or they can be caused by our lifestyle. Many psychological problems can also upset sleep. These include anxiety, depression, anger, guilt, shame and stress at school or in relationships. For example, if we have depression, we may find that it takes us several hours to get off to sleep. We then may wake up several hours earlier than normal feeling as if we haven’t rested at all.
