How Exercise Affects Your Brain


Hello and welcome to another video! Let me start this video by telling that almost
everything you know about exercise is wrong. We usually associate exercise with loosing
weight but thats a big misconception, in fact exercise is the least productive way to loose
weight, so if you are thinking to loose weight, exercise should be the last on your to do
list. Because exercise seems to have completely
different affects than we all have thought. In a book called Spark that was published
in 2008 by John Ratey, proved that Exercise has more effect on your brain than any other
parts of your body. Surprised? Even I was when I read the book. Exercise turns to be a secret recipe to boost
your motivation, focus and memory. Its like a magic pill that instantly boosts
your brain capabilities. In fact, Exercise boosts your mental abilities
more than drugs such as Zoloft that has significant impact on your mental abilities. How? well before we answer that question, don’t
forget to hit that subscribe butting and the bell besides it to never miss another video. Lets first understand how the brain works
in the first place! Your Brain isn’t that fixed organ that cannot
be changed, its an adaptable organ that changes exactly like any other muscle on your body,
like when you lift a weight for example, you strengthen your arms. The more you use it, the stronger and more
flexible it becomes. unlike your arms muscles, Remember that your
brain is the most important organ in your body. Everything we do and think and feel is governed
by how our brain cells, or neurons, connect to one another. And what connects them are neurotransmitters. There are many different kind of neurotransmitters
in your brain, but the ones we will focus on this video are Dopamine, Serotonin and
Norepinephrine I know that it sounds already little complicated
but I promise that I will simplify it as much as possible. The first one is Dopamine, a neurotransmitter
thats responsible for your motivation. It seeks and searches for a reward to keep
you motivated. It provides you with the motivation to do
things. If you ever wanted to buy something, learn
or win. Its all because of the dopamine, it searches
for the potential reward that you might get out of it which drives you to do that thing,
so that you can get that reward. In other words, The reasons that you are unmotivated
is because your dopamine level is low. In fact, researches tried to experiment and
turned off the dopamine receptor in the brain of a rat, and the results were astonishing. The rat became so lazy that it chose to starve
to death and didn’t moved to eat the food even when the food was in in the cage, because
it was no longer motivated. And human brains work in the same way. Your Dopamine determines your level of motivation. And the good news is that. Studies have proved that exercise instantly
and significantly boosts your dopamine level, which means that it will instantly make you
feel motivated. If you are wondering, How long you should
exercise to get that dopamine boost. Dont worry, we will talk about that in a moment. The second neurotransmitter is Serotonin. Its is basically the police man of your brain,
It influences your mood, anger, and aggressiveness, and helps to keep your brain’s activity
under control. In other words, if you feel anxious and depressed,
or stressed out, thats probably because your Serotonin level is low. And thats why all of antidepressant pills
are focused on increasing your serotonin level, because thats what gets you out of depression
and reduces your stress. And guess what again?! Studies have shown that exercise have direct
influence on your serotonin’s level, which means, that the best cure to depression is
to simply, exercise. Now, the last neurotransmitter is Norepinephrine. Its responsible for your attention. If you are struggling to stay focused, thats
more likely because of low Norepinephrine. It works like the other 2 neurotransmitters
we talked about. High levels of it sharpens your attention
and low levels of it makes it hard to focus. Almost all of the drugs affect these neurotransmitters. Cocain for example increase your dopamine
level, therefore makes you feel really great. imagine if you could increase all of this
neurotransmitters at the same time, without any drug. Thats exactly what exercise is for, thats
why the author of the book calls it – the magic pill. But that not the whole story. There is something else. Exercise also boosts your memory and learning
abilities and thats because of protein called brain-derived neurotrophic factor or BDNF
in short. Studies have shown that, the part of your
brain thats responsible for your memory and learning has BDNF. The great part of is that, BDNF gets unleashed
when our blood is pumping, it Grows your Brain cells and increase your learning capacity. In other words, exercise can directly improve
your memory. Imagine, how would your day be, if could boost
your motivation, mood and attention instantly every single morning. And increase your memory and learning capacity
on the top of that. well, all what you need to do is to start
your day with an exercise. but how many hours do you need to exercise? According to the author of the book, 6 hours
in a week is enough. That can keep your neurotransmitters high
throughout the day. But its way much better if you exercise right
before studying or working. because at that moment your neurotransmitters
are at the highest level and BDNF is just unleashed. Thats why you feel, energetic, motivated and
inspired after a morning jog. So right before you start working on that
project, do yourself a favour and exercise for around 5 to 10 minutes. If you want to know about the brain and how
exercise affects it, then go and check out the book- Spark. I have left the link the description of the
