Respiración lenta: calma en cinco minutos

3 minutos de lectura

La tensión no te suelta en todo el día, la irritación salta por cualquier tontería y por la noche la cabeza sigue «trabajando». La respiración lenta es una de las formas más sencillas de calmar el sistema nervioso. Funciona sin fuerza de voluntad y sin condiciones especiales.

Por qué funciona

Una inspiración lenta y, sobre todo, una espiración larga pasan el sistema nervioso del modo «alarma» al modo «calma». Es un reflejo: no hace falta convencerse. Unas seis respiraciones por minuto durante solo cinco minutos aumentan la variabilidad del pulso y bajan las hormonas del estrés.

Los métodos conductuales —la respiración, la atención plena, la terapia cognitivo-conductual— enseñan al sistema del estrés a calmarse solo y superan en eficacia a los suplementos «antiestrés». «Adaptógenos» es una palabra de marketing, no un grupo de medicamentos.

Cómo hacerlo

Hombros relajados, respira con la barriga. Si te mareas, respira menos profundo y un poco más rápido.

Quién debe tener más cuidado

Con asma, respira con calma, sin retener el aire ni hacer fuerza. Si empieza una crisis, para y usa tu medicación habitual.

Qué puede estorbar

Qué esperar

Fíjate en con qué frecuencia te invaden la tensión y la irritación. Si tienes anillo o reloj, puedes comparar la variabilidad del pulso en días con respiración y sin ella: es una señal de recuperación, no una medición de hormonas. Registra cómo te sientes en VIA-L.

Si no ayuda

Si el bajón, la irritabilidad o la ansiedad duran más de dos semanas y te impiden hacer vida normal, es motivo para ir al médico. Más en el artículo «Irritabilidad, apatía, “nada me alegra”».
