Research has shown that focused attention (FA) meditation can combat stress, and that open monitoring (OM) can help with emotion regulation. A more advanced technique, known as “nondual” or “open awareness”, begins to dissolve the illusory distinctions between oneself and the rest of the world, and can even provide meditators with flashes of creative or spiritual insight.

Nondual awareness is a state of mind that helps people to think outside their boxes – the “boxes” being our established mental models of how the world works and our place in it.

We build these mental models through learning over the course of a lifetime. They are invaluable, but over time they can become increasingly rigid and unfit for purpose. Rather than helping, they perpetuate old habits and preclude fresh insights.

What happens in your brain as you become more aware of how the mind works?

It’s perfectly normal to experience emotions such as anger, frustration and anxiety as you sit in front of your computer fielding work messages. The trouble starts when these feelings spiral out of control, causing chronic stress and harming your mental and physical wellbeing.

Meditations that involve open monitoring or “OM” (such as the guided meditation below) teach us to notice when negative thoughts and feelings arise – then simply let them go. We learn to become more aware of these mental events without getting involved with them.

What happens in your brain and body during focused attention meditation?

In focused-attention (FA) meditation, the meditator directs their attention towards a neutral bodily sensation, and gently returns it to that sensation whenever they notice that their mind has wandered. In Shamatha meditation, for example, the focus of attention is the sensations associated with breathing in and out.

Focusing our attention in this way helps to replace the fight-or-flight response with the relaxation response. This kind of meditation activates the “parasympathetic nervous system”, which is the branch of the autonomic (or “involuntary”) nervous system that restores calm after an immediate threat has passed. The parasympathetic nervous system slows our breathing and heart rate, for example, and promotes digestion.

What happens in your brain as you check your emails?

The “fight-or-flight” response evolved in our distant ancestors to prime their hearts, muscles and lungs for action, giving them that vital extra boost to escape ravenous predators or see off aggressive rivals. After the immediate threat had passed, a “relaxation” or “rest and digest” response kicked in to restore their overexcited bodies to a state of calm better suited for more restful activities, such as feeding and grooming.

But in modern humans, technologies such as social media and email can keep our fight-or-flight response constantly switched on by continually presenting us with stimuli that provoke feelings of excitement, fear or aggression.

Can acid dissolve the social isolation of autism and Asperger’s syndrome?

Aaron Paul Orsini felt utterly alone in the world: emotionally numb and devoid of any sense of connection with anybody, including himself. Sunk deep in depression since his teens, he spent much of his time alone in his bedroom, as he puts it, “trying to figure out how the game of being human worked … I kept going to therapy. I kept reading books. I kept working at my desk job. I kept trying new medications. I kept failing, time and time again, with the simple act of identifying the emotional needs of myself and others.”

He spoke to his therapist about his struggles to maintain contact with friends and make new ones, “and how even one-on-one moments felt very confusing at times. I was physically close to people such as my girlfriend, but still very much emotionally distant, from her, myself, and really, everyone in my life.”

At 23 he was at last given a diagnosis that made sense of his tortured efforts to connect socially: autism spectrum disorder. But while the revelation was intellectually interesting, he says, it left him in precisely the same bind: unable to make sense of his own emotions or others’, “feeling irretrievably broken” and increasingly having thoughts about ending it all.

Meditation brightens mood by pumping up dopamine levels

In an age of instant gratification and limited attention spans, why would anyone take up meditation? Perhaps for its soothing, stress-busting effects? Focusing on their breath or a mantra, even beginners start to notice the calming influence of their body’s “relaxation response”, the physiological flipside of the adrenaline-fuelled fight-or-flight response. Among other things the relaxation response slows respiration and heart rate, eases muscle tension and lowers blood pressure, and the changes are associated with a quieting of the brain’s “default mode network”, responsible for mind-wandering, rumination and worry.

But can that really be the whole story?

A peaceful mind is a wonderful thing and for many this is the biggest incentive to meditate regularly – not least for those of us prone to anxiety and depression – but there is another, related benefit that has received scant scientific or medical attention: meditation can be pleasurable, even ecstatic. In the Buddhist meditation known as jhana, for example, the early stages are characterised not only by feelings of peacefulness, but also joy and happiness.

A puke bucket and an ancient medicine: is ayahuasca the future of PTSD therapy?

I’m sitting on a blue plastic, wipe-down mattress with my back to a wooden pillar. Within arm’s reach on the floor is a small torch to light my way to the toilet during the night, on the other side an orange plastic bucket to puke into. As the light fades my four companions, each with his or her own plastic mattress and bucket, disappear from view while on every side the barks, croaks, growls and cries of jungle life grow louder. Twenty minutes ago I gulped down a draught of the bitter psychedelic brew known as ayahuasca and I have convinced myself that I can feel its hot, unstoppable progress through my body, from my seething guts into my veins and onwards to my brain.

This is hardly a recreational drug experience, what with the nausea, vomiting and diarrhoea, not to mention the possibility of a truly terrifying trip, yet thousands now beat a path to Peru, Ecuador and Brazil every year to drink ayahuasca. Some are just looking for an exotic thrill, but others hope for enlightenment and healing from this ancient plant medicine. In the past few years, many of them have been war veterans desperate to escape the nightmares of post-traumatic stress disorder.

Mindfulness shows promise in the treatment of schizophrenia

I’ve known Andy (not his real name) since we were at college together in the 1980s. In those days he was a drummer in his own Heavy Metal band, a bundle of untamed energy. His friends joked that he reminded them of Animal from the Muppets. Above all else he loved partying and being the centre of attention. But the sudden death of his father halfway through his course hit Andy hard. He started to spend more and more time alone in his room with his books, obsessively reading and thinking. Pastimes that had once given him pleasure no longer held any appeal.

The old, extroverted Andy never returned, and shortly after graduating – ejected from the relative calm, stability and familiarity of college life – he began to suspect he was the target of a conspiracy involving the government, the military and several people we knew. Fearing for his life, he lashed out at a stranger in a public park and wound up in a police cell. A few weeks later he was diagnosed with paranoid schizophrenia and sent to a secure psychiatric hospital. Continue reading “Mindfulness shows promise in the treatment of schizophrenia” →

Surely there’s a middle way between drugs and psychotherapy for treating mental illness?

Xanax and Valium pills

“Do you have Valium? I’m worried I won’t be able to sleep again tonight.” In truth, when I sent this text to a friend late one afternoon last April, I was more than worried. I was petrified. I hadn’t slept for three nights and knew perfectly well my mental health was deteriorating.

Meditation research: from “career suicide” to mainstream science

Meditating at sunset

“Disbelieving and hostile” is how Herbert Benson describes the reaction of fellow cardiologists at Harvard Medical School in the early 1970s when they learned he was studying the physiological effects of transcendental meditation. They thought he’d sold out to the hippies. “I had to conduct two careers at that time,” the 80-year-old told me over the phone from Boston. “One as a cardiologist and the other as ‘my crazy thing’.” At one point there was a real possibility he could be thrown out of Harvard.
