Comment le cortisol perturbe le sommeil et ce que les données probantes suggèrent
Le cortisol suit un rythme circadien précis, et lorsque ce rythme est altéré par un stress chronique, il peut en résulter un sommeil fragmenté, des réveils matinaux précoces et un cycle auto-entretenu de dérégulation hormonale. Comprendre les mécanismes à l'origine de cette perturbation ouvre la voie à des stratégies pratiques et fondées sur les données probantes pour restaurer une architecture normale du sommeil.
Créé avec l'IALa relation entre le cortisol et le sommeil n'est pas fortuite. Le cortisol est une hormone dotée d'un rythme quotidien étroitement programmé, et lorsque ce rythme est perturbé, les conséquences touchent presque tous les aspects de la santé métabolique et neurologique. Pour de nombreuses personnes, le fait de se réveiller à 2 h ou 3 h du matin, en état d'alerte et dans l'incapacité de se rendormir, peut être l'expression directe de cette dérégulation hormonale plutôt qu'un simple problème comportemental.
Créé avec l'IAL'architecture circadienne du cortisol et son importance pour le sommeil
Le cortisol ne se maintient pas à un niveau fixe tout au long de la journée. Selon Thomas DeLauer, il suit une courbe circadienne, augmentant progressivement à partir d'environ 2 h du matin et atteignant son pic environ 30 minutes après le réveil. Cette montée matinale est un événement physiologique normal et nécessaire, fournissant le signal d'éveil qui aide le corps à passer du sommeil à l'état de veille. Le soir, en revanche, devrait représenter le creux de cette courbe, lorsque le cortisol descend suffisamment bas pour permettre au système nerveux parasympathique de prendre le dessus et au sommeil de s'installer.
