Bostezo excesivo - Overview

Nombres alternativos

Bostezo en exceso

Definición:

Bostezar consiste en abrir la boca involuntariamente mientras se realiza una inhalación profunda y prolongada de aire, lo cual generalmente se hace como resultado de somnolencia o cansancio. El bostezo excesivo es el que sucede con más frecuencia de la que se esperaría, incluso si la somnolencia y el cansancio no están presentes.

Consideraciones:

El bostezo es una respuesta normal a la fatiga y a la somnolencia, pero el bostezo excesivo puede ser ocasionado por una reacción vasovagal. Dicha reacción es causada por la acción de un nervio, llamado el nervio vago, sobre los vasos sanguíneos y puede ser indicio de un problema cardíaco.

El bostezo normal se puede presentar cuando alguien más bosteza.
