Cansado, ansioso, hinchado, dolorido, mal dormido: la mayor\u00eda de las personas los tratan como problemas separados.

Probablemente no pienses en ellos como conectados.<\/span><\/p>

El cansancio que el sue\u00f1o no arregla, los pensamientos ansiosos que no se calman, el intestino que act\u00faa sin motivo, las noches en que est\u00e1s despierto.\u00a0<\/span><\/p>

Los dolores, los resfriados frecuentes, la sensaci\u00f3n de que no est\u00e1s corriendo bien.<\/span><\/p>

La mayor\u00eda de las personas tratan estos problemas como problemas separados y los persiguen con soluciones separadas, a veces con un especialista diferente para cada uno.<\/span><\/p>

\"Cuando veo a alguien con ese grupo completo, no veo seis problemas\", dice el experto en cerebro. \"Veo un sistema desequilibrado. Casi todos esos s\u00edntomas son lo que parecen cuando un solo nervio, el que se supone mantiene a tu cuerpo calmado y regulado, deja de hacer su trabajo.\"<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

Ese nervio es el vago, y la idea es m\u00e1s simple de lo que suena.<\/b><\/p>

Tu sistema nervioso tiene dos modos: un modo de estr\u00e9s que te hace vibrar, y un modo de recuperaci\u00f3n que te calma y te repara.<\/span><\/p>

Est\u00e1s destinado a moverte con fluidez entre ellos.<\/span><\/p>

El vagus corre por el lado recuperado y act\u00faa como freno.<\/span><\/p>

Cuando ese freno se debilita, algo que los m\u00e9dicos llaman desregulaci\u00f3n del sistema nervioso, o deterioro del nervio vago, su sistema se atasca inclin\u00e1ndose hacia el estr\u00e9s y no puede reiniciar.<\/span><\/p>

Y como el vagus llega a casi todos los sistemas principales, el coraz\u00f3n, los pulmones, el intestino, el sistema inmunol\u00f3gico y el cerebro, un vagus da\u00f1ado no aparece en un solo lugar. Aparece en todas partes.<\/span><\/p>

Por eso un nervio puede disfrazarse de seis problemas no relacionados.<\/b><\/p>

Normalmente no es que el nervio est\u00e9 roto, sino que su tono ha ca\u00eddo y el sistema ha perdido el equilibrio.<\/span><\/p>

La parte alentadora, a la que volveremos, es que se puede entrenar el tono vagal.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Est\u00e1s atrapado en un c\u00edrculo vicioso de pensamientos negativos<\/h2>

Las mismas preocupaciones juegan en un bucle.<\/span><\/p>

Repasas la conversaci\u00f3n, ensayas el peor escenario y rodeas el mismo pensamiento, y ninguna cantidad de razonamiento hace que se detenga.<\/span><\/p>

Esta es una de las se\u00f1ales m\u00e1s claras de un freno vagal d\u00e9bil.<\/b><\/p>

Tu detecci\u00f3n de amenazas est\u00e1 destinada a se\u00f1alar un peligro y luego hacer silencio una vez que haya pasado.<\/span><\/p>

Cuando el vagus no puede hacer que vuelvas a bajar, esa alarma se mantiene encendida, por lo que tu mente sigue escaneando y centr\u00e1ndose en las mismas preocupaciones, que es exactamente lo que es un ciclo de pensamiento negativo.<\/span><\/p>

El interruptor sigue ah\u00ed.<\/span><\/p>

Tu sistema nervioso acaba de perder el acceso f\u00e1cil a \u00e9l.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

La niebla no se despejar\u00e1.<\/span><\/p>

Pierdes el hilo a mitad de la oraci\u00f3n, la palabra que quieres no vendr\u00e1, y organizar un pensamiento simple se siente como andar por el barro, as\u00ed que ordenas en lugar de enfrentar el peque\u00f1o esfuerzo de cocinar.<\/span><\/p>

Esta es la niebla mental, y es una de las se\u00f1ales m\u00e1s comunes de un sistema nervioso desregulado.<\/span><\/p>

Cuando tu sistema est\u00e1 atascado en el modo de supervivencia, aparta recursos del cerebro pensante y los dirige hacia la alarma, por lo que el pensamiento claro y organizado es lo primero que hay que hacer.<\/span><\/p>

El tono vagal bajo tambi\u00e9n est\u00e1 vinculado a la inflamaci\u00f3n de bajo grado que deja tu cabeza pesada, lenta y nublada.<\/b><\/p>

As\u00ed que la niebla no es pereza o falta de concentraci\u00f3n.<\/span><\/p>

Un entrenamiento duro, una semana estresante o una enfermedad menor te golpea y te mantiene all\u00ed mucho m\u00e1s tiempo del que deber\u00eda.<\/span><\/p>

La recuperaci\u00f3n es el lado del modo de recuperaci\u00f3n de tu sistema nervioso que vuelve a entrar en acci\u00f3n, y la variabilidad de la frecuencia card\u00edaca, el n\u00famero que sigue tu anillo o reloj, es esencialmente una lectura en vivo de lo fuerte que es tu tono vagal.<\/span><\/p>

Conclusi\u00f3n?<\/i><\/b><\/p>

Un HRV bajo o estancado es una de las se\u00f1ales m\u00e1s claras y medibles de que el nervio est\u00e1 da\u00f1ado, porque significa que tu sistema tarda en calmarse despu\u00e9s de cualquier cosa que lo empuje.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Te cuesta conciliar el sue\u00f1o, te despiertas a las 3 de la ma\u00f1ana, te rechinas los dientes o te despiertas despu\u00e9s de una noche entera sin sentirte descansado.<\/span><\/p>

El sue\u00f1o profundo y reparador es la parte m\u00e1s parasimp\u00e1tica de tu noche, la etapa que el vago est\u00e1 destinado a recorrer.<\/span><\/p>

Cuando el nervio est\u00e1 da\u00f1ado, y el sistema permanece medio alerta despu\u00e9s del anochecer, no puedes caer en ese sue\u00f1o profundo, y la estructura de la noche se desmorona.<\/span><\/p>

Hinchaz\u00f3n, calambres, el balanceo entre lento y urgente, un intestino que reacciona al estr\u00e9s antes de que incluso lo hayas registrado.<\/span><\/p>

El vagus es el principal cable de comunicaci\u00f3n entre tu intestino y tu cerebro.<\/b><\/p>

Cuando est\u00e1 da\u00f1ado, esa l\u00ednea se vuelve ruidosa y las se\u00f1ales se cruzan, por lo que la digesti\u00f3n falla y el intestino reacciona de manera exagerada a las cosas que deber\u00eda manejar en silencio.<\/span><\/p>

Dolores difusos, un cuerpo que se siente inflamado o una oleada de resfriados y bichos que no puedes sacudir.<\/span><\/p>

Uno de los trabajos m\u00e1s tranquilos del nervio vago es actuar como freno a la inflamaci\u00f3n y ayudar a regular tu respuesta inmune.<\/span><\/p>

Cuando el nervio est\u00e1 da\u00f1ado, ese freno se debilita, por lo que la inflamaci\u00f3n es menos controlada, dej\u00e1ndote dolorido, m\u00e1s sensible al dolor y m\u00e1s propenso a enfermarte.<\/span><\/p>

\"Este es el replanteamiento con el que quiero que la gente se vaya\", dice un experto en cerebro l\u00edder. \"Deja de tratar los s\u00edntomas como una lista. Empezar a preguntar por qu\u00e9 el sistema que los subyace est\u00e1 desregulado. Corregir la regulaci\u00f3n, y la lista tiende a acortarse por s\u00ed sola.\"<\/span><\/p>

Y aqu\u00ed est\u00e1 la parte alentadora que se prometi\u00f3 antes: el tono vagal no es fijo.<\/span><\/p>

Se comporta como un m\u00fasculo, y se puede fortalecer.<\/span><\/p>

Es exactamente por eso que la estimulaci\u00f3n del nervio vago se ha trasladado de la cl\u00ednica a algo que se puede hacer f\u00e1cilmente en casa.<\/b><\/p>

Los vagos, de todos los lugares, se encuentran en tu o\u00eddo externo, por lo que una se\u00f1al suave aplicada justo all\u00ed puede alcanzarlo sin nada invasivo.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
