Meditation and yoga can 'reverse' DNA reactions which cause stress, new study suggests

Summary:
Mind-body interventions (MBIs) such as meditation, yoga and Tai Chi don't simply relax us; they can 'reverse' the molecular reactions in our DNA which cause ill-health and depression, according to a study.


Mind-body interventions (MBIs) such as meditation, yoga and Tai Chi don't simply relax us; they can 'reverse' the molecular reactions in our DNA which cause ill-health and depression, according to a study by the universities of Coventry and Radboud.

The research, published in the journal Frontiers in Immunology, reviews over a decade of studies analysing how the behaviour of our genes is affected by different MBIs including mindfulness and yoga.

Experts from the universities conclude that, when examined together, the 18 studies -- featuring 846 participants over 11 years -- reveal a pattern in the molecular changes which happen to the body as a result of MBIs, and how those changes benefit our mental and physical health.

The researchers focus on how gene expression is affected; in other words the way that genes activate to produce proteins which influence the biological make-up of the body, the brain and the immune system.

When a person is exposed to a stressful event, their sympathetic nervous system (SNS) -- the system responsible for the 'fight-or-flight' response -- is triggered, in turn increasing production of a molecule called nuclear factor kappa B (NF-kB) which regulates how our genes are expressed.

NF-kB translates stress by activating genes to produce proteins called cytokines that cause inflammation at cellular level -- a reaction that is useful as a short-lived fight-or-flight reaction, but if persistent leads to a higher risk of cancer, accelerated aging and psychiatric disorders like depression.

According to the study, however, people who practise MBIs exhibit the opposite effect -- namely a decrease in production of NF-kB and cytokines, leading to a reversal of the pro-inflammatory gene expression pattern and a reduction in the risk of inflammation-related diseases and conditions.

The study's authors say the inflammatory effect of the fight-or-flight response -- which also serves to temporarily bolster the immune system -- would have played an important role in humankind's hunter-gatherer prehistory, when there was a higher risk of infection from wounds.

In today's society, however, where stress is increasingly psychological and often longer-term, pro-inflammatory gene expression can be persistent and therefore more likely to cause psychiatric and medical problems.

Lead investigator Ivana Buric from the Brain, Belief and Behaviour Lab in Coventry University's Centre for Psychology, Behaviour and Achievement said:

"Millions of people around the world already enjoy the health benefits of mind-body interventions like yoga or meditation, but what they perhaps don't realise is that these benefits begin at a molecular level and can change the way our genetic code goes about its business.

"These activities are leaving what we call a molecular signature in our cells, which reverses the effect that stress or anxiety would have on the body by changing how our genes are expressed. Put simply, MBIs cause the brain to steer our DNA processes along a path which improves our wellbeing.

"More needs to be done to understand these effects in greater depth, for example how they compare with other healthy interventions like exercise or nutrition. But this is an important foundation to build on to help future researchers explore the benefits of increasingly popular mind-body activities."

No es nada nuevo,, la mente es un órgano que actua sobre otros órganos y celulas...

" In the past two decades, mind–body interventions (MBIs; refer to Table A1 for a list of abbreviations frequently used throughout this paper) have been gaining empirical support and recognition by mental health professionals. While some MBIs, such as yoga, Tai Chi, and Qigong, have a strong physical component, others like meditation and mindfulness, breath regulation techniques, and the relaxation response (RR) are mainly sedentary. Despite the variability in these techniques, they all seem to produce various psychological benefits on healthy and clinical populations, such as the reduction of perceived stress [e.g., Ref. (1)], the alleviation of depression [e.g., Ref. (2)], decreases in anxiety [e.g., Ref. (3)], or to help in coping with a chronic medical disease [e.g., Ref. (4)]. However, it is less clear what are the mechanisms underpinning the self-reported benefits of MBIs. Neuroimaging studies suggest that MBIs increase gray matter in the brain regions related to emotion regulation, learning, memory, self-referential processes, and perspective taking (5–7). However, a recent meta-analysis on structural and morphological brain changes associated with one type of MBI (meditation) casts some doubt on the generalization of such results, as different techniques and length of practice are associated with different neural patterns (8)."


Todavía no se sabe qué es la mente... muchos piensan que es el cerebro, otros piensan (con suficientes pruebas) que la mente es otra entidad, asociada al cerebro...

Lo que para algunos nos queda en claro es que la fuerza de voluntad, a pesar de que puede estar influenciada por muchos mediadores químicos (endógenos y exógenos), en su esencia poco tendría que ver con el cerebro en sí mismo...

¿Es el cerebro el creador de los fenómenos psíquicos o estamos ante un cambio de paradigma inevitable?

"Todos los días, información científica nueva surge, que no puede ser explicada usando el modelo clásico Newtoniano (se refiere al causa efecto material), y está exigiendo que surja un nuevo paradigma (científico) que pueda explicar fenómenos como la telepatía, clarividencia, presentimiento, precognición, experiencias fuera del cuerpo, sanación psíquica, comunicación posterior a la muerte, experiencias cercanas a la muerte y la reencarnación.

El paradigma materialista que considera que el cerebro es la única causa de la Conciencia y de los fenómenos psíquicos está siendo desafiado por un nuevo paradigma que parece demostrar que no existe una relación de causa efecto entre la actividad cerebral y los fenómenos psíquicos, sino una correlación entre ambos, ya que estos fenómenos pueden experimentarse sin el cuerpo y apareciendo su origen en una memoria - extracerebral (¿Campo Cósmico, Conciencia Cósmica?). Por supuesto, el cerebro claramente participa en la manifestación de la Conciencia, pero esto no significa que se pueda concluir que el cerebro crea la Conciencia. Recientes hallazgos nos obligan a considerar un aspecto, no físico, sino espiritual y transpersonal. "

Hace decadas que el funcionamiento cerebro se estudia como redes de informacion y no con la mecanica de Newton. Los "fenomenos " de la telepatia, reencarnacion y otras magufadas no necesitan explicarse porque ni siquiera hay pruebas (cientificas) que existan.
