Meditate – Rick Hanson, PhD


Can you come home to yourself?

The Practice:
Meditate.

Why?

Meditation is to the mind what aerobic exercise is to the body. Like exercise, there are many good ways to do it and you can find the one that suits you best.

Studies have shown that regular meditation promotes mindfulness (sustained observing awareness), whose benefits include decreased stress-related cortisol, insomnia, symptoms of autoimmune illnesses, PMS, asthma, falling back into depression, general emotional distress, anxiety, and panic, and increased immune system factors, control of blood sugar in type 2 diabetes, detachment from reactions, self-understanding, and general well-being.

In your brain, regular meditation increases gray matter (neuronal cell bodies and synapses) in the:

  • Insula – Handles interoception (sense of your own body); self-awareness in general; empathy for the emotions of others
  • Hippocampus – Key role in personal recollections, visual-spatial memory, establishing the context of events and calming down both the amygdala (the alarm bell of the brain) and production of stress hormones like cortisol
  • The prefrontal cortex (PFC) – Supports the executive functions, self-control, and guiding attention

Regular meditation also:

  • Increases activation in left PFC, which lifts mood
  • Increases the power and reach of very fast, gamma range brainwaves, which promotes learning
  • Preserves the length of telomeres, the caps at the ends of DNA molecules; longer telomeres are associated with fewer age-related diseases (This was found in a three-month retreat, and may not apply to meditation in general.)
  • Reduces cortical thinning due to aging in the insula and PFC

Meditation is the quintessential training of attention. Since attention is like a vacuum cleaner – sucking its contents into your brain through what’s called β€œexperience-dependent neuroplasticity” – getting better control of your attention is the foundation of changing your brain, and thus your life, for the better.

The research summarized above just scratches the surface of the benefits of meditation. It is you saying to the world (and yourself): I’m going to step off the hamster wheel now. This time is for me. It is a way to center on being rather than doing (what a relief!). And a way to see the mind streaming along, transient and insubstantial, an unreliable basis for lasting happiness, not worth chasing after or struggling with.

The minutes I spend meditating are usually the best ones of my day. They feel like coming home. It’s good to be home.
