In some cases, people may find themselves sleepless for as long as a day and a half and in extreme cases, even more.

Causes of Non 24 Hour Sleep Wake Syndrome

Although Non 24 Hour Sleep Wake Syndrome often affects blind people, it can also affect sighted people. In some reported cases, the syndrome was said to result due to a head injury or a previous neurological disorder.

Several experiments suggested that the syndrome is somehow linked to the functioning of Retina. People having light sensitivity issues were found more vulnerable to Non 24 Hour Sleep Wake Syndrome. It was concluded that the brain does not react well to intense light.

Interestingly, light is said to synchronize the body clock and hence people with even the minimal visibility are seldom subjected to the syndrome. However, for blind people, as there are no photic signals that reach the brain, the body clock does not sync and hence the sleeping schedule is expected to be disrupted.

In some extreme cases, hypnotism and sleep stimulant were also used and were found effective against this syndrome.

In case of blind people, drugs and medicines are also prescribed. Several researches also indicate that use of melatonin is also effective in reducing the effects of Non 24 Hour Sleep Wake Syndrome.
