The brain-changing benefits of exercise | Wendy Suzuki


What if I told you there was something
that you can do right now that would have an immediate,
positive benefit for your brain including your mood and your focus? And what if I told you that same thing
could actually last a long time and protect your brain
from different conditions like depression,
Alzheimer’s disease or dementia. Would you do it? Yes! I am talking about the powerful effects
of physical activity. Simply moving your body, has immediate, long-lasting
and protective benefits for your brain. And that can last
for the rest of your life. So what I want to do today
is tell you a story about how I used my deep
understanding of neuroscience, as a professor of neuroscience, to essentially do an experiment on myself in which I discovered
the science underlying why exercise
is the most transformative thing that you can do for your brain today. Now, as a neuroscientist,
I know that our brains, that is the thing in our head right now, that is the most complex structure
known to humankind. But it’s one thing
to talk about the brain, and it’s another to see it. So here is a real preserved human brain. And it’s going to illustrate two key areas
that we are going to talk about today. The first is the prefrontal cortex,
right behind your forehead, critical for things like decision-making,
focus, attention and your personality. The second key area is located
in the temporal lobe, shown right here. You have two temporal lobes in your brain,
the right and the left, and deep in the temporal lobe
is a key structure critical for your ability to form and retain new long-term
memories for facts and events. And that structure
is called the hippocampus. So I’ve always been fascinated
with the hippocampus. How could it be that an event
that lasts just a moment, say, your first kiss, or the moment your first child was born, can form a memory
that has changed your brain, that lasts an entire lifetime? That’s what I want to understand. I wanted to start and record
the activity of individual brain cells in the hippocampus as subjects were forming new memories. And essentially try and decode how
those brief bursts of electrical activity, which is how neurons
communicate with each other, how those brief bursts either allowed us
to form a new memory, or did not. But a few years ago,
I did something very unusual in science. As a full professor of neural science, I decided to completely switch
my research program. Because I encountered something
that was so amazing, with the potential to change so many lives that I had to study it. I discovered and I experienced
the brain-changing effects of exercise. And I did it in a completely
inadvertent way. I was actually at the height
of all the memory work that I was doing — data was pouring in, I was becoming known in my field
for all of this memory work. And it should have been going great.
It was, scientifically. But when I stuck my head
out of my lab door, I noticed something. I had no social life. I spent too much time
listening to those brain cells in a dark room, by myself. (Laughter) I didn’t move my body at all. I had gained 25 pounds. And actually, it took me
many years to realize it, I was actually miserable. And I shouldn’t be miserable. And I went on a river-rafting trip —
by myself, because I had no social life. And I came back — (Laughter) thinking, “Oh, my God,
I was the weakest person on that trip.” And I came back with a mission. I said, “I’m never going to feel
like the weakest person on a river-rafting trip again.” And that’s what made me go to the gym. And I focused my type-A personality on going to all the exercise
classes at the gym. I tried everything. I went to kickbox,
dance, yoga, step class, and at first it was really hard. But what I noticed is that after every
sweat-inducing workout that I tried, I had this great mood boost
and this great energy boost. And that’s what kept me
going back to the gym. Well, I started feeling stronger. I started feeling better,
I even lost that 25 pounds. And now, fast-forward a year and a half
into this regular exercise program and I noticed something that really
made me sit up and take notice. I was sitting at my desk,
writing a research grant, and a thought went through my mind that had never gone
through my mind before. And that thought was, “Gee, grant-writing is going well today.” And all the scientists — (Laughter) yeah, all the scientists
always laugh when I say that, because grant-writing never goes well. It is so hard; you’re always
pulling your hair out, trying to come up with that
million-dollar-winning idea. But I realized that
the grant-writing was going well, because I was able
to focus and maintain my attention for longer than I had before. And my long-term memory —
what I was studying in my own lab — seemed to be better in me. And that’s when I put it together. Maybe all that exercise
that I had included and added to my life was changing my brain. Maybe I did an experiment on myself
without even knowing it. So as a curious neuroscientist, I went to the literature to see
what I could find about what we knew about the effects
of exercise on the brain. And what I found was an exciting
and a growing literature that was essentially showing everything
that I noticed in myself. Better mood, better energy,
better memory, better attention. And the more I learned, the more I realized
how powerful exercise was. Which eventually
led me to the big decision to completely shift my research focus. And so now, after several years
of really focusing on this question, I’ve come to the following conclusion: that exercise is
the most transformative thing that you can do for your brain today for the following three reasons. Number one: it has
immediate effects on your brain. A single workout that you do will immediately increase
levels of neurotransmitters like dopamine, serotonin
and noradrenaline. That is going to increase your mood
right after that workout, exactly what I was feeling. My lab showed that a single workout can improve your ability
to shift and focus attention, and that focus improvement
will last for at least two hours. And finally, studies have shown that a single workout
will improve your reaction times which basically means that you are going to be faster
at catching that cup of Starbucks that falls off the counter, which is very, very important. (Laughter) But these immediate effects are transient,
they help you right after. What you have to do is do what I did, that is change your exercise regime,
increase your cardiorespiratory function, to get the long-lasting effects. And these effects are long-lasting because exercise actually
changes the brain’s anatomy, physiology and function. Let’s start with my favorite
brain area, the hippocampus. The hippocampus — or exercise actually
produces brand new brain cells, new brain cells in the hippocampus,
that actually increase its volume, as well as improve
your long-term memory, OK? And that including in you and me. Number two: the most common finding
in neuroscience studies, looking at effects of long-term exercise, is improved attention function
dependent on your prefrontal cortex. You not only get
better focus and attention, but the volume of the hippocampus
increases as well. And finally, you not only get
immediate effects of mood with exercise but those last for a long time. So you get long-lasting increases
in those good mood neurotransmitters. But really, the most transformative thing
that exercise will do is its protective effects on your brain. Here you can think
about the brain like a muscle. The more you’re working out, the bigger and stronger your hippocampus
and prefrontal cortex gets. Why is that important? Because the prefrontal cortex
and the hippocampus are the two areas that are most
susceptible to neurodegenerative diseases and normal cognitive decline in aging. So with increased exercise
over your lifetime, you’re not going to cure
dementia or Alzheimer’s disease, but what you’re going to do
is you’re going to create the strongest, biggest hippocampus
and prefrontal cortex so it takes longer for these diseases
to actually have an effect. You can think of exercise, therefore, as a supercharged 401K for your brain, OK? And it’s even better, because it’s free. So this is the point in the talk
where everybody says, “That sounds so interesting, Wendy, but I really will only
want to know one thing. And that is, just tell me
the minimum amount of exercise I need to get all these changes.” (Laughter) And so I’m going to tell you
the answer to that question. First, good news: you don’t have to become
a triathlete to get these effects. The rule of thumb is you want to get
three to four times a week exercise minimum 30 minutes an exercise session, and you want to get aerobic exercise in. That is, get your heart rate up. And the good news is,
you don’t have to go to the gym to get a very expensive gym membership. Add an extra walk around the block
in your power walk. You see stairs — take stairs. And power-vacuuming can be as good
as the aerobics class that you were going to take at the gym. So I’ve gone from memory pioneer to exercise explorer. From going into the innermost
workings of the brain, to trying to understand how exercise
can improve our brain function, and my goal in my lab right now is to go beyond that rule of thumb
that I just gave you — three to four times a week, 30 minutes. I want to understand
the optimum exercise prescription for you, at your age,
at your fitness level, for your genetic background, to maximize the effects of exercise today and also to improve your brain
and protect your brain the best for the rest of your life. But it’s one thing to talk about exercise,
and it’s another to do it. So I’m going to invoke my power
as a certified exercise instructor, to ask you all to stand up. (Laughter) We’re going to do
just one minute of exercise. It’s call-and-response,
just do what I do, say what I say, and make sure you don’t punch
your neighbor, OK? Music! (Upbeat music) Five, six, seven, eight,
it’s right, left, right, left. And I say, I am strong now. Let’s hear you. Audience: I am strong now. Wendy Suzuki: Ladies,
I am Wonder Woman-strong. Let’s hear you! Audience: I am Wonder Woman-strong. WS: New move — uppercut, right and left. I am inspired now. You say it! Audience: I am inspired now. WS: Last move — pull it down,
right and left, right and left. I say, I am on fire now! You say it. Audience: I am on fire now. WS: And done! OK, good job! (Applause) Thank you. I want to leave you with one last thought. And that is, bringing
exercise in your life will not only give you
a happier, more protective life today, but it will protect your brain
from incurable diseases. And in this way it will change
the trajectory of your life for the better. Thank you very much. (Applause) Thank you. (Applause)

  1. Hi I am from India 32 yeard old and have a daughter of 2 years old please be a guru to her guide her for her future waiting for your reply

  2. And here Iโ€™m thinking exercise, the high from exercise, was all due from endorphins๐Ÿคท๐Ÿพโ€โ™€๏ธ๐Ÿคท๐Ÿพโ€โ™€๏ธ๐Ÿคท๐Ÿพโ€โ™€๏ธ๐Ÿคท๐Ÿพโ€โ™€๏ธ

  3. I understand when advocates say the little things matter, they do. But they don't replace prolonged aerobic exercise.

    That said someone should introduce this lady you BoxVR.

  4. I have watched Wendy Suzuki for years and I love how she evolved this message in the last 2 years. Practice makes perfect! I do this work! It's not easy work and delivering the message well is essential!

  6. It's true. When you exercise, you don't repeat the pattern you're in, you do new things or things that you usually don't do and that puts your brain in a different perspective. You experience & think things you didn't before. I discovered this thing when i came from a totally different zone of mind wherein i was sad & depressed. As i headed to gym on the first day, i started running on the treadmill & BOOM! i felt completely past my problems. Because running diverted my mind and i started seeing things which were blocked due to the thoughts that kept my mind surrounded. So, even if you workout for like 30 mins that is enough to calibrate your brain to a new patters which is very much required & healthy for your brain. Similarly, try taking a different route home or any place that you usually go to..it exhilarates a vert different energy in you. The thing is whatever you do don't keep repeating the same, get out of the zone, do things differently and add some new ones to keep your brain feeling fresh and detoxify it.

  7. I'm on board with exercising, but to counter this argument about it making you "smarter". Sir Isaac Newton, Nikola Tesla, Marie Curie, Johann Wolfgang von Goethe, Confucius, Thomas Willis, etc. didn't "hit the gym" yet were incredibly intelligent and successful individuals.

  10. I wonder how this could help the ADD brain ๐Ÿง  especially kids with an ADD parent or two. If the children with such genetics have more active life styles, could they lessen the chances of ADD affecting them?

  11. It's crazy how everyone always repeat each other just in their own sophisticated way. To me she's just another skilled motivational speaker with something beneficial to speak about.

  12. I'm not really attracted to cars, but this one is quite attractive wink wink

    Anyway, Calisthenics are a great way to build muscle and strength, i have gotten results from it, you dont always need a gym.
    Weight would be a bonus, to make things harder when you advance.

    And it helps to compete with another person and having fun doing it, you can spot each other and push each other further.

    Kinda wish i had a younger sibling to slave around now, but a GF would also do the trick…

  13. I am here for my curiosity and i can acknowledge that what Mrs. Suzuki claims is true 100%.
    Once in our life time we fail and sink into the chair and let the good taste of food and ice cream comfort us. But we forget that its a death trap and its a path of no return.
    We fall into despair and hopelessness and all it takes is one instant moment of thought where you say to yourself "I feel so disgusted and ugly about myself" and then boom…

    You run. It hurts but you keep running. You change your diet and you change your mentality.
    You erase white sugar from your life, it is a poison my friends, remember that.
    You force yourself to run, just run and if you need to cry then cry as you run.
    You decide that not a single day will pass without running, cold, rainy, windy, gloomy you run.
    You will realize that we belong to life and life wants us to see it and live it.
    Your occupation matters not, your salary does not all that matters is you taking the decision to move and build your body, mind and spirit.

  14. Update : I signed up for gym today because i was so inspired by this video. I have been struggling a lot with my research because of poor memory but now all that is about to change. BRING IT ON MR GYM INSTRUCTOR!

  15. 1:38 listen to her what is the job of Prefrontal cortex? decision making! right. read this
    " No! If he does not stop, We will take him by the naseyah (front of the head), a lying, sinful naseyah (front of the head)! (Quran, 96:15-16)" more about this and other facts explained here in many languages https://www.islam-guide.com/ch1-1-d.htm
    Why did the Quran describe the front of the head as being lying and sinful? What is the relationship between the front of the head and lying and sinfulness? because we DECIDE TO LIE and do wrong in that area of the brain? loving your creator, doing sport, reading in many field, revising what you read and learned daily just before going to bed, and setting small goals in an incremental fashion little by little to install new habit gradually is the right formula otherwise exercise alone is a band aid short effect and short boost and then back again to lazy mind, life and possible depression we all have been there. cheers.

  16. this is why we should not make machines to do work for us , we should just share work .
    work for each other , NOT against each other as this disgusting capitalist system brainwashes you to believe .

  17. Okay I'm not trying to propagate any negativity here. But my dad used to be in military. So obviously he used to be the most physically active person in our family. Yet he was diagnosed with Alzheimer's dementia at 57 with all his neurocognitive functions gradually declining day by day. Now he is reduced to just a living zombie. So is it safe to assume that this video doesn't apply to everyone???

  18. I wonder, I've been climbing for 4 months like 4 times a week, but I still feel anxious and negative alot of time. Should I apply cardio to get these cognitive benefits? Or should I be getting them already?

  19. My father has Alzheimers disease and its been devastating for the entire family. Its something that terrifies me and keeps me up at night. This lecture gives me hope that this disease can one day be cured. I get emotional thinking about my father but also the millions of people suffering from this disease and their loved ones who are affected as well.

  20. Scriptures say that women are not allowed to teach nor usurp authority over men. You must love Jehovah your God with all your heart and with all your soul and with all your mind and with all your strength. You must love your neighbor as yourself. Jesus the anointed is Lord!

  21. i am from india we dont have any play ground left if i do exercise my relatives parents and neigbors force me to study or play cricket which got 0 exercise in cricket ….nearest playground is 25 km far i only go there on sundays and its filled with cricket playing kids no football no basketball, swimming nor kickboxing ..motherfuking country

  22. Awesome stuff – I train 6/7 days and can attest to this talk – some of the people I surf with are in their late 50s and early 60s – music / instrument playing and physical training can lead to a happy and โ€œfullโ€ life … move like Jagger ๐ŸŽต
