Mental Rest

Mental illness, or also known as mental disorder, according to wikipedia, is a psychological or behavioral pattern associated with distress or disability that occurs in an individual and certainly is not a part of normal development.

Such phenomenon is believed to be caused by two types of factors. Firstly, in many cases, individuals who suffer from mental disorders are resulted from genetic vulnerabilities. In other cases, environmental stressors, such as working pressure, family tensions, negative social influences and etc, appear to be another common factor.

Now, there is another new branch of exploration as far as mental illnesses are concerned. Young healthy adults aged between 17 and 24 years old, and who got less than an average of 5 hours' sleep appear to have threefolds of risk in developing mental illness, comparing to those who sleep for about 8 or 9 hours each night averagely.

Such study involved participants from countries such as New South Wales and Australia. Professor Glozier, who took charge in the mentioned study, stressed that sleep disturbance appears to be an important symptom in mental disorders, for example depression.
