Les bases neuroscientifiques des effets du thé sur la santé mentale

Derick E. Vergne

Abstract

Les composés du thé pourraient bénéficier à l'humeur et au sommeil en agissant sur des voies neurotransmettrices communes. Il a été démontré que le thé vert à faible teneur en caféine améliore la qualité du sommeil et réduit la fatigue chez les adultes d'âge moyen et les personnes âgées. Les composants du matcha pourraient moduler le circuit de la peur via la régulation de la dopamine et de la sérotonine. La L-théanine pourrait réduire l'anxiété et améliorer le sommeil sans induire de sédation, potentiellement par modulation sérotoninergique et GABAergique. Associée à l'épigallocatéchine gallate (EGCG), elle pourrait également influencer l'activité du BDNF. Les extraits de thé pourraient agir sur l'axe intestin-cerveau en favorisant la diversité du microbiote, en réduisant l'inflammation et en soutenant la régulation des neurotransmetteurs.
