One day, I had this discussion with 2 of my blind friends about the sleep problems that some blind people have, and the difficulty they encounter when they try to adjust to a certain time difference. Imagine how it is painful and torturous thing when you have a kind of disorder in your sleep pattern. All of us know how this can affect our performance and concentration on our work as professionals, or our studies as students. I decided to ask more about the problem and Google it to see if it is a real or it is nothing more than a discussion between me and my friends.
Surprisingly, I found more than one article and more than one study tackled this issue. In addition to many things a blind person need to cope with in life is this sleep problem. Studies show that some of the completely blind individuals or who don’t have any light perception suffer from a kind of sleep disorder called circadian rhythm disorder. When a normal person gets exposed to light during daytime and darkness at night, the body produces melatonin which stabilizes our normal sleep patterns. Lacking this normal production of melatonin can badly affect the biological clock of the blind who may suffer from sleep problem.
I am actually not a psychiatrist or a psychologist but I found interesting articles tackling this topic so I like to share them with you. Perhaps they can give you more elaboration about what i am trying to say. Sleep Disorders in Blind People is an interesting and easy article, I really recommend you read it.
For those of you who are more interested about the medical aspect of the issue, I also found this more specialized article Sleep Disorders in Blind Patients: News From the Lab, for the Clinic
I don’t want you to understand that all blind people have this problem although it seems that it is some how common. This is also what the studies showed. I just want to share this, it may be important for somebody and of course it is still relevant to the challenges that some blind individuals have to cope with in life.
