What happens to your brain when you meditate?
Nowadays, people see meditation as a treatment for illness.
But what really happens in your brain when you meditate?
Let's find out together in this video.
You can't see or touch tension,
but you can feel its effect on your mind and body.
In short, tension increases your heart rate,
your respiratory rate, and increases blood pressure.
When you meditate,
your mind produces too much of the hormone cortisone.
Too much contact with this hormone
can affect your brain function, immune system, and other organs.
Tension can cause headaches,
anxiety, depression, cardiovascular disease,
and even early death.
Although you can't get rid of the root of tension,
you can reduce its effect on your body.
One of the easiest and most effective techniques to reduce tension is meditation.
A program where you focus your attention on the inside
to create a deep relaxation state.
Although meditation has been practiced for thousands of years,
its health benefits are relatively new and promising.
A 18-year-long meditation course
by the Wisconsin-Madison Center for Mental Health
was recently announced.
The results show that the brain of a Buddhist monk
who meditates daily
has reduced the aging process by 8 years
compared to other groups of objects being observed.
The project began in the 1990s
based on the relationship between the psychologist Richard Davidson
and the Dalai Lama.
Davidson, the founder of the Mental Health Center,
began to create a connection between positive emotions
and the health of the brain.
Since then, he has focused his attention on meditation.
Davidson said,
The Dalai Lama encouraged me to practice this traditional meditation method
and study it with scientific tools.
If we find that meditation is really beneficial,
this method will be widely popularized.
The study uses MRI and a special machine
to estimate the age of the brain
through the brain image of a Buddhist monk.
Davidson and the main scientist Nagesh Arnuru
studied the mind of the Tibetan Buddhist monk
Janggir Mingo Rinpoche for 18 years.
Davidson said,
The goal is to understand
whether there is a difference in the aging speed
in the brain of experienced Buddhist monks
compared to new practitioners.
Rinpoche was examined for the first time
in 2002 at the age of 27.
At that time, he completed 9 years of meditation.
He was examined again at the corresponding ages
of 30, 32, and 41.
The last examination was done
when he returned after a 4.5-year journey.
His brain was estimated to be 33 years old,
which is 8 years younger than the actual age.
Researchers compared Rinpoche's brain
with the brain of a group of subjects being closely monitored.
The results showed that
the brain of the monk was aging slower than the others.
The importance of this discovery is too obvious.
Even with the wrong frequency plus or minus up to 2-3 years,
Davidson said,
If the benefits of meditation are calculated over time,
this will have a great impact on health and happiness.
Especially now,
amid the coronavirus pandemic,
everyone can benefit from meditation.
It is designed to remind us
that goodness comes from ourselves.
I think the most interesting thing
is that we can influence our brain
and change the speed it ages
through doing things that are good for health.
Researchers said
they were excited to see how Rinpoche's brain
would develop
and how this research could improve overall health.
What happens to your brain when you meditate?
Meditation develops different areas in your brain.
Your brain develops through neural connections.
Neural cells process information in your brain
to create neural pathways
that are responsible for your thoughts,
feelings, and actions.
When you continuously do an activity,
you strengthen the neural connections
to help develop the areas in your brain.
This process is similar to meditation.
While the research on meditation is still in its early stages,
some early research has found that
meditation can lead to
an increase in the level of gray matter in the cornea,
which is an important area of the brain
for memory and other areas of the brain,
as well as an increase in the thickness of the brain
in the frontal lobes,
increasing the level of gray matter
and the left side of the cornea
to support learning, awareness, and memory,
which leads to a better retention of activities
and a better concentration of actions.
The increase in the frontal lobes
and the thickness of the brain
allow for the function of awareness,
attention, and self-awareness.
Over the past decade,
researchers have found that
if you focus on breathing,
the brain will reconstruct itself
to make it easier to focus.
If you practice calm acceptance while meditating,
you will develop a brain
that can recover better from stress.
And if you meditate while nurturing
love and confidence,
your brain will develop
in a way that you feel more natural
when connecting with others.
Christopher Rowe, a psychologist
at Harborview Children's Hospital,
said that if you look at the results
from 6 to 12 months after meditation,
from 20 to 30 minutes a day,
you can see changes
in the brain structure
as well as changes in function.
Stimulating the nervous system
Another benefit of meditation
is that it can neutralize
your nervous system
or fight back.
When you encounter a threat,
your nervous system
releases stress hormones
to help you get rid of
or fight back the stress.
When the danger passes,
your nervous system
will activate and allow you to rest.
According to Rowe,
through meditation,
you are basically stopping
your nervous system
and activating your nervous system.
During this time,
it can help reduce pain,
emotion, stress, and anxiety.
He also emphasized
how to neutralize your nervous system
through meditation
can reduce emotional response
by realizing
how not to judge
what happens to you
while meditating
and then let it pass.
You can avoid fighting
or running away
Meditation can help you
improve your ability to focus
in two ways.
First, it can help you
focus better on something specific
while ignoring the distractions.
Second, it can help you
have more possibilities
to perceive what is happening
around you,
help you have a fuller
view of the present time.
Some of the most interesting
studies on meditation
at the Quartzman Laboratory
on Image and Behavior
at the University of Wisconsin
in Madison,
together with Richard Davidson
and the Laboratory on Neuroscience
at the University of Wisconsin
have shown that
meditation focuses
on one thing
such as breathing
or looking at a object
and activating important areas
of the brain to control attention.
This is also true
for novice meditators,
short-term practitioners,
experienced meditators
whose activation is even stronger
in these areas
if meditation focuses on
the attention of the brain.
Experienced meditators
with more than 44,000 hours
of meditation practice
show less activation
in these areas
even though their effect
on the attention of the brain
is much stronger.
This shows that
people can increase
their ability to focus
immediately by learning
a simple meditation technique
and it can even
make more progress.
To see if meditation
reduces the lack of attention,
participants have to
perceive two things
happening in a row
published in the magazine
Plos Biology.
It is revealed that
the meditation training
has improved the ability
to perceive the two changes
of the participants
without reducing the accuracy.
Brainwaves
monitoring brain activity patterns
showing the correct changes
at each point
in the brain activation process
show that
the meditation training
uses less mental energy
to focus on the first goal
which helps the mind
to free itself
to perceive the next thing
which makes it easier
to focus on the brain.
The final result
shows that
meditation can increase
our ability to control
the limitations of the brain
especially for those
who have limited
mental energy.
Although your attention
is a limited source,
you can learn to do more
with the mental energy
you have with meditation
to reduce stress for you.
The study also shows that
meditation can help people
who are confused.
Philippe Gaudin,
director of Stanford University
Psychological Applied Neuroscience
The common practice is
to realize the present moment
by focusing on the sound,
breath, feeling in the body,
thinking, feeling, observing
without judging
and trying to change
what you perceive.
In his research,
those who participate in
a 8-week meditation course
to reduce stress
meet once a week
in a classroom
to practice yoga
with body awareness
as well as to discuss
the experience in daily life.
Before and after meditation,
those who participate
are brainwashed
by an MRI
which examines the function
of the brain,
not the structure of the brain.
The MRI monitors which brain
consumes more energy
during meditation
The brain scans in Gaudin's research
show a surprising pattern.
After meditation,
those who participate
are more active in the brain
related to processing information
when they react to negative statements
about themselves.
In other words,
they pay more attention to negative statements
than what they did before meditation.
They also show a reduction of activity
in the nuclear core,
an area related to stress and anxiety.
The research shows that
many discoveries about meditation
teach people with anxiety
how to deal with thoughts
and sad feelings
without being stopped.
Most people ignore
uncomfortable or negative thoughts
about them.
The MRI shows that
people with anxiety
are learning how to observe
negative thoughts
without reacting

All meditators
have different emotional reactions to sounds.
Meditators with more experience
show that
the brain reacts more
in important areas
to deal with physical sensations
and emotional reactions,
especially with painful sounds.
Researchers also observe
an increase in heart rate
with brain changes.
These discoveries show that
meditators have real empathy
and meditators with experience
feel more self-aware.
In other words,
self-awareness seems to make the brain
open more naturally to connect with others.
These techniques
may have benefits
other than the experience of self-awareness.
A study by Professor of Psychology
Barbara Fredrickson
and her colleagues
at the University of North Carolina,
Chapel Hill and Michigan
shows that
a 7-week study
also increases the daily experience
of participants in joy,
gratitude and hope.
The more people participate in meditation,
the better they feel.
Participants also say
they feel more self-acceptance,
are supported by society,
have a purpose in life
and satisfaction in life,
while rarely experiencing
real and emotional symptoms.
This study provides strong evidence
that self-awareness
can open a more meaningful connection
to life.
Although meditation
can cause surprising changes
in your brain and vision,
it doesn't happen overnight
and it's not a cure-all.
Learn how to let go
of your expectations.
Simply put, meditation
is a difficult experience,
but it's really important.
The more you practice in a moment
the better you will get.
