Colour Temperature Change Its Relationship to Health

From the Latin circa (about) dies (a day), the circadian rhythm is the twenty-four-hour cycle of light/dark, wakefulness/sleep to which most human physiologic processes are set. At regular intervals each day, the body tends to become hungry, tired, active, listless, energized. Body temperature, heart-beat, blood pressure, hormone levels, and urine flow rise and fall in this relatively predictable, rhythmic pattern - a pattern initiated and governed by exposure to sunlight and darkness. 

However, in the absence of natural light our body clocks may lose or gain a little time. This in turn could lead to the desynchronization of different rhythms. For example, in the absence of sufficient environmental light the sleep-wake and associated rest-activity rhythms may lengthen to a cycle of between 30 and 48 hours, while the temperature rhythm may remain at a period of, say, 25 hours.

In the absence of correction from the daylight cycle provided by the sun, the biological clock tend go out of sync affecting our physical and mental health.

 Such desynchronization of the body's intricate rhythms is suspected to trigger problems:

 Ø      hormonal imbalances,

Ø      sleep disorders and

Ø      mood disturbances

 

Light has a great impact on synchronizing our circadian rhythms.

What we do is to use the natural daylight to "fine-tune" our body clock (or to apply a correction), so that the body clock is in synch with the external environment.

The benefits of full spectrum a obvious. But do we have the same light intensity over the day?

 The sun wakens us in the morning with a colour temperature of 3.400 º K which increases to 5.500 º K by midday, in order to decrease again to 3400 º K towards the evening.

These changes in the colour temperature and the brightness have important functions with regard to our body biology and its rhythm of rest and activity.

 By way of effecting changes in the colour temperature, connected with the intensity fluctuations, the Uni-Lux Daylight-System  imitates the natural daily rhythm from raise dawn to sunset glow.
