Cronobiología

Ritmos circadianos

Definición de ritmos circadianos

La cronobiología es una rama de la biología que estudia los ritmos circadianos, es decir, los ritmos biológicos que fluctúan a lo largo de un ciclo de 24 horas.

Los dos tipos de ritmos circadianos:

  • Ritmos fisiológicos: patrón de vigilia-sueño, temperatura corporal, etc.
  • Ritmos biológicos: melatonina, cortisol, hormonas de crecimiento.

Todos estos diferentes ritmos están sincronizados y controlados por nuestro reloj biológico, ubicado en el núcleo superquiasmático, que a su vez se encuentra en el hipotálamo dentro de nuestro cerebro.

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.
