Sleep disorder

Disorder of the sleep-wake-pattern

These days, many people live and work surrounded by artificial light of a relatively low intensity, for example approximately 500 lux.

This may be light enough for our eyes to be able to see but for our brain it remains night. We need at least 2,500 lux in order to positively influence the hormones and neurotransmitters in our brain.

The consequence: the rhythm occurring naturally in the body is not in harmony with the day/night rhythm of the majority of the population. Millions of people experience this in a way whereby their normal performance levels are somehow impaired and day to day problems occur more and more often.

People who suffer from an irregular sleep-wake-pattern are often so tired during the day that they have to sleep and then, as a result, are unable to sleep at night.

The extreme are night people - "owls"- who suffer from delayed sleep-phases; they cannot get to sleep until long after midnight. They therefore feel the next day that they have not had enough sleep; they feel tired for a long period of time and do not become active until the afternoon.

The extreme morning people - "larks" - torment themselves with advanced sleep-phases. They go to bed in the early evening and get up very early the next morning. "Larks" have problems because they become too tired too early in the evening and awake at an extremely early hour the following morning.

Shift-workers and travellers between the continents and time zones can also say a thing or two about disorders of the sleep-wake-pattern (jet lag syndrome).

With light therapy using DAVITA light boxes it is now possible to considerably alleviate the disorders of the sleep-wake-pattern and the resulting negative effects.

Having had a good night’s sleep and being concentrated - DAVITA light boxes can help you.
