🧠 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.

Keywords

💡Meditation

Meditation is a practice where an individual uses a technique such as mindfulness or concentration to train attention and awareness, with the aim of achieving mental clarity and emotional calmness. In the video, meditation is explored as a means to improve physical, emotional, and spiritual well-being, with scientific evidence supporting its positive effects on the brain and body.

💡Default Mode Network (DMN)

The Default Mode Network is a network of brain regions that are active when the brain is at rest and not focused on the outside world. It plays a role in mind-wandering, self-referential thinking, and is associated with improved memory, self-awareness, and goal setting as mentioned in the script when discussing the effects of meditation.

💡Alpha Waves

Alpha waves are brain waves with a frequency between 8 and 12 Hz, associated with a state of wakeful relaxation. The video highlights that meditators have higher levels of Alpha waves, which are linked to reduced negative mood, tension, sadness, and anger, illustrating the calming effect of meditation.

💡Gray Matter

Gray matter refers to the parts of the brain and spinal cord consisting mainly of neuron cell bodies, as opposed to white matter which consists of the myelinated axons. The script notes that meditation can increase the density of gray matter in areas associated with learning, memory processing, and emotion regulation, suggesting that meditation can enhance cognitive functions.

💡Amygdala

The amygdala is an almond-shaped part of the brain involved in processing emotions, particularly those related to fear and stress. The video script indicates that meditation can lead to a decrease in gray matter in the amygdala, which may contribute to reduced stress and fear responses.

💡Heart Rate Variability (HRV)

Heart Rate Variability is the variation in time between successive heartbeats. It is a measure of the heart's ability to adapt to the body's changing needs. The script suggests that meditation can increase HRV, which is beneficial for the proper transportation of oxygen and carbon dioxide throughout the body.

💡Immune Function

Immune function refers to the ability of the immune system to defend the body against infections and diseases. The video mentions a study where meditators produced a greater number of antibodies and had increased immune function after being given the flu virus, indicating that meditation can bolster the immune system.

💡Telomeres

Telomeres are protective caps at the ends of chromosomes that help prevent damage to the DNA. The video script explains that meditation can lead to an increase in telomere length, which is associated with reduced cell death and a lower risk of diseases such as cardiovascular disease, diabetes, Alzheimer's, and cancer.

💡Telomerase

Telomerase is an enzyme that can add DNA to the ends of chromosomes, counteracting the shortening of telomeres. The video suggests that psychological interventions, such as meditation, can affect the activity of telomerase, thereby potentially slowing down the aging process and reducing the risk of age-related diseases.

💡Cellular Level

The cellular level refers to the scale at which cells, the basic structural and functional units of living organisms, operate. The video script discusses how meditation can have effects at the cellular level, such as influencing telomere length and protecting DNA from damage, which underscores the profound impact of meditation on overall health.

💡Psychological Intervention

Psychological intervention refers to therapeutic or educational strategies aimed at improving mental health and well-being. The video highlights that meditation, as a form of psychological intervention, can decrease stress and have a direct effect on telomerase, an enzyme that helps maintain telomere length and, by extension, cellular 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 one’s 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 wasn’t 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, Alzheimer’s and cancer.

Amazingly, when cancer survivors completed a meditation program, their bodies showed

significant increases in telomere length.

It’s 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 don’t 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 ‘working out’ your brain with extra health benefits.

And since your brain controls, well...all of you, why not relax and say ‘om’ 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!

We’ve got answers to your most asked burning questions, persistent rumours, and unexplained

phenomenon!

Whether you’re a huge science fan, or just a curious mind, the book has something for

everyone, and we’re so excited for you to read it and show off to your new found knowledge

to all your friends!
