Cómo el trabajo de la respiración transforma las emociones y el cerebro

¿Y si la clave para transformar la mente y las emociones estuviera en algo tan simple como el aire que entra y sale de los pulmones? La ciencia empieza a confirmar lo que antes parecía intuición: respirar de manera consciente no solo oxigena el cuerpo, también puede modificar la forma en que pensamos, sentimos y gestionamos nuestras emociones. Lejos de ser un acto mecánico, el llamado breathwork se posiciona como una práctica poderosa que impacta directamente en el bienestar emocional y en el funcionamiento del cerebro.
En los últimos años, investigadores han profundizado en cómo técnicas intensivas, especialmente combinadas con música evocadora, logran provocar cambios medibles a nivel corporal y mental.
Un experimento pionero, basado en técnicas avanzadas de imagen y monitoreo fisiológico, permite ver con claridad inédita el impacto real que una sesión guiada de respiración puede tener sobre el miedo, las emociones y las conexiones cerebrales.
¿Puede una sesión de respiración intensa acompañada de música cambiar lo que sentimos y pensamos en solo veinte minutos? Eso buscó demostrar Amy Amla Kartar y su equipo de la Brighton and Sussex Medical School. El estudio, publicado en PLOS One, combinó tecnología de neuroimagen y monitoreo fisiológico para medir objetivamente el impacto del breathwork.

El ensayo incluyó a personas en casa, en laboratorio y dentro de un resonador magnético. Todos realizaron ciclos de 20 a 30 minutos de respiración rápida continua con música seleccionada.
Luego, reportaron sus sensaciones mientras los investigadores medían variabilidad de la frecuencia cardíaca y flujo sanguíneo cerebral. “Queríamos entender, desde lo subjetivo hasta lo fisiológico, cómo el trabajo de la respiración transforma la actividad interna”, explicó Kartar.
Los resultados, presentados literalmente en el artículo, muestran que la intensidad de los estados alterados de conciencia se relacionó de manera directa con la activación del sistema nervioso simpático, medido por una disminución de la variabilidad de la frecuencia cardíaca.
Al mismo tiempo, la resonancia magnética reveló una reducción significativa del flujo sanguíneo en el opérculo izquierdo y la ínsula posterior —zonas asociadas a la percepción interna del cuerpo y la respiración—, mientras se observó un aumento progresivo del flujo en la amígdala derecha y el hipocampo anterior, regiones implicadas en el procesamiento de memorias emocionales.

El equipo de la Brighton and Sussex Medical School destacó: “Los cambios más profundos en el flujo sanguíneo cerebral se asociaron con sensaciones de unidad, éxtasis y liberación emocional, conocidas colectivamente como ‘oceanic boundlessness’”. Los participantes reportaron una disminución del miedo y de las emociones negativas, y no se registraron efectos secundarios desfavorables.
En el estudio, la mayoría de los participantes experimentó lo que la ciencia llama oceanic boundlessness: una sensación intensa de unidad, paz y claridad mental, acompañada de la pérdida del miedo y una percepción ampliada de sí mismos.
Este fenómeno, definido y medido en investigaciones internacionales como una categoría científica —y no como una marca o término exclusivo—, suele aparecer en prácticas religiosas profundas y en estudios con psicodélicos, pero aquí surge solo con el trabajo de la respiración y música evocadora.
“Muchos describieron una profunda conexión y tranquilidad, lo que confirma que el breathwork puede ser una herramienta potente para modificar el estado emocional”, subrayó Amy Kartar. Lo más relevante: no se observaron efectos negativos, lo que respalda la seguridad del método.

Esta investigación marca la primera vez que se utiliza neuroimagen para mapear en tiempo real las modificaciones cerebrales durante el trabajo de la respiración guiada.
El Dr. Alessandro Colasanti, investigador principal, indicó: “El breathwork es una herramienta poderosa y natural de neuromodulación. Regula el metabolismo en todo el cuerpo y el cerebro, y tiene un enorme potencial como intervención terapéutica transformadora para condiciones que suelen ser tanto angustiantes como incapacitantes”.
El estudio incorporó no solo reportes subjetivos, sino también variables fisiológicas objetivas, como la variabilidad de la frecuencia cardíaca y los patrones regionales de flujo sanguíneo cerebral. Esta aproximación fortalece la solidez de los hallazgos y sienta bases para futuras réplicas e investigaciones adicionales.
Según los autores, aún persisten “preguntas abiertas” que requieren estudios con más participantes y grupos de control capaces de aislar el efecto específico de la música. “Nuestro estudio es de carácter exploratorio y requiere replicación con muestras más numerosas y grupos de control que permitan aislar el efecto específico de la música”, advirtió Kartar.

A pesar de las limitaciones, los datos reunidos ofrecen una validación sólida de cómo el trabajo de la respiración —potenciado por la música y un entorno seguro— puede generar cambios medibles en el cerebro y las emociones, señalando un horizonte nuevo para el desarrollo de terapias clínicas no farmacológicas.
Respirar es un acto tan antiguo como la humanidad misma, pero la ciencia revela ahora la profundidad de su influencia en la mente y el cuerpo.
El trabajo de la respiración o breathwork emerge como una técnica capaz de transformar la relación entre la subjetividad y los procesos fisiológicos. Como concluye Amy Kartar: “Fue emocionante explorar un área tan novedosa; aunque muchas personas reconocen anecdóticamente los beneficios del breathwork, este estilo ha recibido muy poca atención científica. Estamos profundamente agradecidos a quienes participaron y permitieron avanzar en el conocimiento”.
A la espera de nuevos estudios, la respiración guiada se perfila como una vía accesible, segura y poderosa para fortalecer la salud emocional.

Iran moves hundreds of millions in crypto during nationwide internet blackout, report reveals

NEWYou can now listen to Fox News articles!
EXCLUSIVE: Cryptocurrency infrastructure linked to Iran’s Islamic Revolutionary Guard Corps (IRGC) continued operating during the country’s nationwide internet blackout after the Feb. 28 U.S.–Israeli strikes, a cyber intelligence report reviewed by Fox News Digital claims. It allowed hundreds of millions of dollars in crypto to move out of the country.
Omri Raiter, founder and CEO of RAKIA, a cyber intelligence firm that develops data analysis platforms used by governments and security agencies, told Fox News Digital his team began monitoring Iranian cryptocurrency activity in real time after the attacks and quickly detected a surge of funds leaving Iranian-linked crypto accounts.
«We’ve seen a surge of funds since the first hours of the war,» Raiter said. «It started with tens of millions in the first hours, and it grew to hundreds of millions and more. Money was just flowing out from Iranian crypto accounts.»
Wallets linked to the IRGC received more than $3 billion in cryptocurrency in 2025, according to the internal report based on blockchain intelligence data cited by RAKIA. The report also cites publicly available data from blockchain analysis firm Chainalysis, which estimated Iran’s cryptocurrency ecosystem reached $7.78 billion in activity in 2025.

Raiter said the data suggests Iran has developed a significant crypto-based financial infrastructure capable of operating even during heavy sanctions and communications shutdowns.
«The IRGC has been financing proxy operations through the very same crypto corridors that sanctions were designed to shut down,» Raiter said.
The U.S. Department of the Treasury sanctioned cryptocurrency exchanges tied to Iranian actors Jan. 30, marking one of the first times the U.S. targeted entire digital asset platforms rather than individual wallets for sanctions evasion linked to the Islamic Revolutionary Guard Corps.
Treasury Secretary Scott Bessent said the move was part of a broader effort to disrupt financial networks connected to Tehran, Iran.
«The Treasury will continue to pursue Iranian networks and corrupt elites who enrich themselves at the expense of the people,» Bessent said in a Treasury press release in January. «This also applies to attempts by the regime to use digital assets to circumvent sanctions.»
The recent surge appears to reflect two parallel trends: funds moving to support Iran’s regional proxy networks and money being moved by individuals connected to the regime seeking to protect their personal wealth, according to RAKIA’s analysis.
«The proxy war funding and the personal capital flight are two sides of the same coin,» Raiter said. «They move through the same pipelines.»

Raiter said the firm identified cryptocurrency flows connected to networks previously associated with Iran-backed groups.
«Some of the accounts we saw are connected to areas where money historically flows to proxy wars,» he told Fox News Digital, citing activity linked to Lebanon and Yemen.
«Some of it could be people inside the IRGC trying to move their own money,» Raiter said. «But when you see the scale and the timing, it looks coordinated.»
The report produced by RAKIA claims the activity continued even after Iran imposed a sweeping internet shutdown across the country. National connectivity dropped to roughly 1% of normal levels during the blackout, according to internet monitoring group NetBlocks.

Despite that shutdown, RAKIA researchers said they detected more than 1,100 active cryptocurrency nodes operating inside Iran.
«When the internet is at one percent and you still see over a thousand active crypto nodes, you’re not looking at retail users,» Tom Malca, RAKIA’s head of cyber and AI research, said in the report. «Those nodes require dedicated bandwidth, stable power and deliberate exemption from the shutdown.»
RAKIA researchers said the activity suggests specialized infrastructure continued operating even as millions of Iranian civilians were cut off from the internet.
Most of the nodes were concentrated in the Tehran–Qom corridor, according to the report, an area that includes major government and IRGC institutions. Smaller clusters were detected in Iranian cities, including Isfahan, Mashhad, Tabriz and Kermanshah, according to the analysis.

RAKIA said its investigation relied on a combination of network monitoring and publicly available blockchain intelligence.
The Iranian mission to the United Nations in New York declined to comment on the report’s claims.

Florida Republicans send SAVE Act–style proof-of-citizenship voting bill to DeSantis’ desk

NEWYou can now listen to Fox News articles!
Florida lawmakers are sending Republican Gov. Ron DeSantis a strict elections bill modeled after the federal SAVE America Act strongly championed by President Donald Trump that mandates voters verify their citizenship when registering.
Lawmakers in Tallahassee, Florida, in the GOP-dominated state House approved the measure in a 77–28 vote Thursday, hours after the bill passed the Republican-controlled state Senate 27–12. The votes in both houses of the Florida legislature were nearly entirely along party lines.
DeSantis, a supporter of what he calls «the Florida version of the SAVE Act,» is expected to sign the measure when it reaches his desk.
«Although Florida has already enacted much of what the federal legislation contemplates, this will further fortify our state as the leader in election integrity,» the governor highlighted in a social media post.

The developments in Florida come as the federal bill faces an uncertain future in Congress.

The SAVE Act, which stands for Safeguard American Voter Eligibility, narrowly passed the GOP-controlled House in February mostly along party lines. But it’s stalled in the Senate, where Republicans hold a 53–47 majority in the chamber, far short of the 60 vote threshold needed to pass the bill.
The federal bill would require strict voter ID and proof-of-citizenship requirements across the country. Republicans say the bill is necessary to secure election integrity.
While polls indicate the vast majority of Americans — regardless of the political affiliation — support voter IDs at the polls and preventing noncitizens from voting in federal elections, Democrats argue the bill is not needed, since citizenship already is a requirement to vote and instances of noncitizen voting are rare.

Democrats and voting rights groups also claim that the federal bill would create unnecessary barriers, making it harder for voters to cast a ballot.

Trump, who is intent on holding the Republican congressional majorities in the 2026 midterm elections, said earlier recently that the federal bill should be the top priority in Congress and that if passed, it «will guarantee the midterms» for Republicans.
But the Florida bill’s proof of citizenship requirement wouldn’t take effect until January, after the November 2024 midterm elections. And the bill also doesn’t limit the Sunshine State’s allowance for excuse-free mail-in-voting.
Trump has long railed against mail-in-balloting.

The Florida measure also would prevent college students from using their student IDs when voting in person, but that provision wouldn’t take effect until 2027.
«This bill creates real barriers for everyday Floridians, especially those with the fewest resources,» Democratic state Sen. LaVon Bracy Davis of Orlando argued in a social media post. «It will disproportionately impact working families, seniors, and college students who want to exercise their voice and right to vote.»

And Florida Democratic Party Chair, Nikki Fried charged, «In the cover of night, Florida Republicans made it harder for U.S. citizens to vote.»
«While Democrats, civic groups, and voters voiced their concerns to stop this harmful policy, Republicans decided citizens’ voices didn’t matter and voted to disenfranchise hardworking Floridians,» she added.
The bill would make Florida the most populous state in the nation to mandate proof-of-citizenship to register to vote.
Arizona and Kansas enacted similar requirements in the past two decades, and Louisiana passed a law two years ago.

Proof-of-citizenship bills passed recently in the South Dakota and Utah legislatures, and are awaiting the governors’ signatures.
And in 2024, New Hampshire mandated that all first-time voters show proof of citizenship when registering.
