The Scientific Power of Meditation
Summary
TLDRMeditation's impact on the body is profound, as it activates brain regions linked to reduced anxiety, depression, and increased pain tolerance. It enhances empathy, alters brain wave frequencies like Alpha waves to alleviate negative emotions, and physically changes brain structure by increasing gray matter in areas associated with learning and emotion regulation while decreasing it in the stress-related amygdala. It also improves heart rate variability, immune function, and even extends telomere length, reducing the risk of diseases. Meditation complements a healthy lifestyle, offering cognitive and cellular benefits.

Q & A
What are the primary benefits of meditation as discussed in the script?
-Meditation offers a range of benefits including reduced anxiety and depression, increased pain tolerance, improved memory, self-awareness, and goal setting. It also enhances empathy, reduces negative moods, and can physically change brain structure and function.
How does meditation affect the Default Mode Network in the brain?
-The Default Mode Network is activated during meditation, which is when the mind is at rest and not focusing on the outside world. This activation is linked to improvements in memory, self-awareness, and goal setting.
What differences were found in the brains of Buddhist monks compared to new meditators?
-The region of the brain associated with empathy was found to be much more pronounced in Buddhist monks compared to new meditators.
How does meditation influence brain waves?
-Meditators have higher levels of Alpha waves, which are associated with reduced feelings of negative mood, tension, sadness, and anger.
What physical changes in the brain can be observed after a meditation program?
-After 8 weeks of a meditation program, gray matter density increases in areas associated with learning, memory processing, and emotion regulation. Conversely, the amygdala, which deals with stress and fear, shows a decrease in gray matter.
How does meditation impact blood pressure and heart rate variability?
-Meditation can decrease blood pressure and increase the variability of heart rate, which is critical for the efficient transport of oxygen and carbon dioxide throughout the body.
What effect does meditation have on the immune system, as per the flu virus study mentioned?
-In the study where both meditators and non-meditators were given the flu virus, meditators were able to produce a greater number of antibodies and had increased immune function.
How does meditation affect cellular health, specifically telomeres?
-Meditation can lead to significant increases in telomere length, which are protective protein complexes that help reduce DNA damage and lower cell death. This is particularly beneficial as shortened telomeres are linked to various diseases.
What role does the enzyme telomerase play in the effects of meditation on telomeres?
-The enzyme telomerase is believed to be directly affected by psychological interventions like meditation, particularly by decreasing stress. It counteracts telomere shortening by adding DNA to the shrinking telomeres.
Is meditation a substitute for medical advice or a healthy lifestyle?
-No, meditation is not a substitute for medical advice or a healthy lifestyle. It should be considered a complementary practice that can enhance overall health when combined with proper medical care and lifestyle choices.
What is the metaphor used in the script to describe the effect of meditation on the brain?
-The script uses the metaphor of 'working out' the brain to describe the effects of meditation, suggesting that just as physical exercise builds muscles, meditation can enhance brain function and overall health.
Outlines
π§ The Impact of Meditation on the Brain and Body
Meditation has been practiced for millennia for its spiritual, emotional, and physical benefits. Scientifically, it increases activity in brain regions linked to reduced anxiety, depression, and increased pain tolerance. The Default Mode Network, activated during restful states, enhances memory, self-awareness, and goal setting. Empathy is heightened in experienced meditators, such as Buddhist monks, compared to novices. Meditation also increases Alpha brain waves, which are associated with reduced negative emotions. After eight weeks of meditation, studies show denser gray matter in areas related to learning and memory, while the amygdala, responsible for stress and fear, shows decreased gray matter. Meditation also improves heart rate variability, crucial for oxygen and carbon dioxide transport, and boosts immune function, as seen in meditators' response to the flu virus. On a cellular level, meditation can increase telomere length, reducing DNA damage and cell death, which is linked to diseases like cardiovascular disease, diabetes, Alzheimer's, and cancer. Psychological interventions, particularly stress reduction, affect the enzyme telomerase, which can counteract telomere shortening. While not a medical substitute, meditation offers additional health benefits, akin to exercising muscles for overall health.

Transcripts
For thousands of years people have practiced meditation for spiritual, emotional, and physical
well being.
But from a scientific perspective, how exactly does meditating affect your body?
Does it really do anything?
It all starts in the brain!
During meditation, brain-scans see increased activity in regions directly correlated with
decreased anxiety and depression, along with increased pain tolerance.
The Default Mode Network, in particular, is activated when oneβs mind is at rest and
not focusing on the outside world, and has been found to improve memory, self awareness
and goal setting.
Want to be more caring to your friends and family?
When scientists compared the brains of Buddhist monks to new meditators, they found the region
of the brain associated with empathy to be much more pronounced in the monks.
It also literally changes your brain waves - and we can measure these frequencies.
Meditators have higher levels of Alpha waves, which have been shown to reduce feelings of
negative mood, tension, sadness and anger.
And if that wasnβt enough, it also physically changes our brain shape and size.
Studies found that after 8 weeks of a meditation program, gray matter was more dense in areas
associated with learning, memory processing, and emotion regulation.
And yet the amygdala, which deals with stress, blood pressure and fear, had decreased gray
matter!
When we look at the entire body, not only do we see decreased blood pressure, but it
can also increase the variability of your heart rate.
While this may sound harmful, it actually plays a critical role in properly transporting
Oxygen and Carbon Dioxide throughout your body.
Think your getting sick?
In a study where both meditators and non-mediators were given the flu virus, meditators were
able to produce a greater number of antibodies and had increased immune function.
If we go a little deeper, we can even see changes on a cellular level.
Your chromosomes have protective protein complexes called telomeres, which help reduce damage
to your DNA and lower cell death.
And a shortened telomere length has been linked to several disease such as cardiovascular
disease, diabetes, Alzheimerβs and cancer.
Amazingly, when cancer survivors completed a meditation program, their bodies showed
significant increases in telomere length.
Itβs believed that psychological intervention, particularly decreasing stress, has a direct
effect on the enzyme telomerase, which has been shown to counteract shortening by adding
DNA to the shrinking telomeres.
Of course, meditation is not a substitute for other medical advice or a healthy lifestyle
- we donβt want you leaving this video thinking it will cure cancer.
But much like hitting the gym can grow your muscles and increase your overall health,
it seems that meditation may be a way of βworking outβ your brain with extra health benefits.
And since your brain controls, well...all of you, why not relax and say βomβ every
once in a while.
And if you like working out your brain, be sure to get our AsapSCIENCE book which is
now available for pre-sale at asapscience.com/book!
Weβve got answers to your most asked burning questions, persistent rumours, and unexplained
phenomenon!
