Biological clock

Our biological clock is the congenital mechanism in humans that regulates various periodic bodily functions.

This internal clock is set by external influences, especially by sunlight or daylight.

Nerve pathways link the biological clock to the outside world via the retina of the eye. In this way, light signals can reach the epiphysis or pineal gland, in which they can regulate the release of melatonin, the "sleep hormone". By systematically going to bed late (shift work), by making a long flight in east-west direction (jetlag), or by switching between summer and winter time, the biological clock can become disrupted. It then takes several days before we feel well again. Staying up longer gives less distortion than getting up earlier. For example, in successive shifts, it is important to apply as much as possible a morning-evening-night rotation schedule, not the other way around.

In addition, in home, work, and nursing environments, the sleep-wake rhythm can be negatively affected by light intensities that are (too) low or by specific light colors.

Ocular light controls the rhythm of many body processes, such as the sleep-wake rhythm. As a result, light is the most important time controller of the human biorhythm.

MediluX closely follows the latest developments when researching the functions of the biological clock and the control and lighting technology, which can be used to control the light color and light intensity when necessary.
