Chronobiologie

Tagesrhythmus

Definition von circadianen Rhythmen

Chronobiologie ist ein Zweig der Biologie, der sich mit zirkadianen Rhythmen beschäftigt, also den biologischen Rhythmen, die über einen Zyklus von 24 Stunden schwanken.

Die zwei Arten von zirkadianen Rhythmen:

  • Physiologische Rhythmen: Wach-Schlaf-Rhythmus, Körpertemperatur usw.
  • Biologische Rhythmen: Melatonin, Cortisol, Wachstumshormone.

Diese verschiedenen Rhythmen sind alle miteinander synchronisiert und werden von unserer biologischen Uhr gesteuert, die sich im superchiasmatischen Kern befindet, der wiederum im Hypothalamus unseres Gehirns untergebracht ist.

The biological clock is based on three synchronizers :

Melatonin, also called the “sleep hormone”, which is secreted by the pituitary gland (which gives information about the alternation of day/night) and “resets” the body with its environment.  

Light (alternation night/day) if it is received by the eye receptors in a sufficient quantity and if it is made up of good wave lengths (blue light)  

Lastly, social factors (family life, leisure, sports, etc.) also serve as synchronizers. The main circadian rhythm is the alternation of wake/sleep but other rhythms exist which vary from day to day : body temperature, our cortisol level, melatonin secretion, etc... The body also searches for a temporal balance between itself and the outside world. When our internal clock is no longer synchronized with the actual time, a pathological situation follows, of which the principal symptoms are trouble sleeping, waking up and temperament.

The Luminette reproduces the beneficial effects of the sun and stimulates specific receptors, located in the eyes, which activate the energizing response that light has on the body. It will help you to fight against slumps in energy, allowing you to feel more in shape and it will have a regulatory effect on your sleep patterns.
