my head is aching my legs
are shaking I can’t sleep studies keep piling up in a heap of restlessness
and irritability prevails I’m worried will I fail lack of sleep just mounts oh I’m so
stressed out we’re living through stressful times and stress has become our constant companion
but do you know what exactly happens inside our body when we are stressed in today’s
In the video we are going to talk about three things one is the science of stress in our brain and body
two five very effective solutions to beat stress and finally two bonus tips right at the end
so don’t get stressed and let’s get going hey everyone this is Chetna and you’re watching
chet chat there are two kinds of stress one is use stress or good stress this gives us an extra
a burst of energy and focus when we are playing a competitive sport or giving a presentation and two
the second is distress or bad stress this is the continuous stress which makes us feel burdened
how stress affects the brain now you’ve perhaps been stressed for the past few months thinking
about your future or even your family’s health, this emotion of stress activates the hypothalamus
pituitary-adrenal axis the hpa axis the hypothalamus via the pituitary glands activate the
adrenal glands which are situated atop the kidneys in response the adrenal glands secrete a hormone
called cortisol the stress hormone the body thinks of this as a warning sign as though we’re about to
get eaten up by a bear the cortisol first raises the activity level in the amygdala the fear center
of the brain this gives rise to feelings of anger this is the reason why we tend to lash out when we
are stressed if you want to know by the way more about the signs of anger then watch this video and
I will share a link for you in the description box below have you ever found yourself saying I’m
so stressed I can’t think straight while the amygdala is working overtime cortisol travels
to its next destination the pre-frontal cortex located at the front of our head’s prefrontal
cortex is the thinking and planning part of the brain excess cortisol sustained for long periods
of time causes this region to shrink thereby blurring our rational thinking now another thing
What happens when we are very worked up that we can’t seem to remember where we’ve kept our phone
or our keys even if it’s right in front of us let’s see why that happens the cortisol now
reaches the hippocampus the memory center of our brain excess cortisol lowers the production
of brain cells in this region that is why we tend to forget everything we’ve studied if
we feel very stressed out during an exam now where is this cortisol reached in his
journey to the very cells of the brain too much stress will slow down your response
systems have as well seen someone looking very numb after they’ve encountered major stress but
the worst damage of stress is that over time it can change our cell structure right down to our
DNA shortens the telomeres the shoelace tips of chromosomes which measure a cell’s age do you
know the shorter the telomeres become the shorter their lifespan now not all stress is bad
remember we spoke about eustress or good stress and the experiment conducted by the University of
Wisconsin shows that moderate amounts of cortisol can improve memory while no stress which is
zero milligrams of cortisol or too much stress which is about 40 milligrams of cortisol will
not help you remember what you’ve studied or where you’ve kept your phone but just the right
amount of stress about 20 milligrams of cortisol will help you remember faster so be alert but
not burnt out before we talk about how stress affects the body I would like to give a shout
out to only ladies outfits whose amazing message got a huge number of likes from you and
if you want a shout-out in my next video then leave me a comment below with the hashtag
chet chatters now you must be thinking that if all this is going on inside the brain how am i
feeling stress in my body you’re right to stress affects all body systems and let’s see
how to remember that the body is still thinking of us being attacked by a bear so it believes that
the muscles need oxygen to fight or to run now an amazing sequence of events takes place the
the heart pumps faster increasing blood pressure causing hypertension this huge volume of blood
starts going through our lungs to get oxygenated which means we start panting and getting
breathless to inhale more oxygen now imagine our arteries like pipes which suddenly have high
speed blood gushing inside them the pipes could burst so the body begins to thicken these arteries
by accumulating a sticky substance called plaque which in turn attracts cholesterol and fats extra
thick walls mean that sometimes the openings of the arteries become too narrow and now the heart
has to work doubly hard to push blood through them and all these blocked arteries could lead
to heart attacks did you know that over 60 patients suffering from irritable bowel syndrome
have psychiatric disorders and chronic anxiety another thing you might have noticed people tend
to stress eat before an important occasion you’ll see that since the muscles require quick oxygen
cortisol increases our appetite and signals the body to consume more energy-rich food like carbs
the problem is that there is no actual bear so we are neither running nor fighting and all these
sugars get accumulated as belly fat but don’t get all stressed out hearing this take a deep breath
because I have some tried and tested methods to bust your stress keep calm and meditate on
mindful meditation and yoga regulate breathing reduce heart rate and decrease cortisol levels
in our body stress causes us to breathe faster so we are forcing our body to slow down and do some
reps to de-stress exercise also reduces the levels of the body’s stress hormones adrenaline and
cortisol stimulates and produces endorphins the body is a natural painkiller and mood elevator
so try some home workouts or go for a walk or jog in the fresh air surrender and acceptance
this is my secret sauce to remain stress-free one big cause of stress is us trying to control
In every aspect of our lives practice acceptance surrender and gratitude together and you will
experience the calm flow through your veins and good vibes only you might have heard that confidence is
the key well it’s the key to unlocking some stress people with higher self-esteem are
said to perform better because they have lower cortisol responses to acute stress so they belief in
yourself and repeat I can do it and if you want to know how to increase your self-confidence then
check out this video and I’ll drop a link for you below headphones in stress out listening to your
favorite tracks especially mellow music have a beneficial effect on our body it slows the pulse
and the heart rate down it lowers blood pressure and decreases the levels of stress hormones and
now for the bonus tip dark chocolate, this is my favorite one eating a bar of dark chocolate
helps to keep stress at bay because it contains antioxidants which help in reducing cortisol
levels overthinking is over friendly wizard newt Scamander said my philosophy is that
worrying means you suffer twice we can all learn from him and stop worrying
about situations beyond our control remember just live in the moment so stay
calm peaceful and safe and happy learning

So we can see the overall
representation of the Cauchy stress tensor. So first is stresses acting on x
plane. Now which is the x plane, this is the x plane. So there are two
x planes, this is negative x and this is positive x. So what are the
stresses which are acting, we have sigma xx in the direction of x?
So, all of them are acting on x plane. Then we have sigma XY and sigma xz. Similarly,
on the other side of another plane which is a negative x plane we have sigma XY, sigma xz, and sigma xx.
It is identical but it is on the other side. Then we have stressed on y plane. Now what is
meant by y plane, a plane with y direction as the normal. So you are talking about this and this.
So you have positive y and this is negative y. Similarly, in this, you have
sigma yy, sigma yy, which is the direction, in the direction
of y and you have sigma y x, sigma yz, similarly sigma y x and sigma yz. Then
we have stresses acting on the z plane, what are the stresses acting on the z plane, and
what is the z plane, this is the positive z plane and this is the negative z plane and
this stress is acting as sigma zz, sigma zx, sigma zy. Similarly, here also
you have sigma zz, sigma zx, and sigma zy. So these are the representation of the components
of Cauchy stress on a given control volume. So, all these stress components are acting at
a point. Now we need to keep in mind that I have shown a control volume in the figure, and
that is only for understanding how the stresses are oriented. Otherwise, it does not serve
any purpose. We need to still understand that whatever stress components are there in
the Cauchy stress tensor, it is acting at a point and the control volume, the cuboid is shown only
to indicate the plane on which it is acting. So that’s that notion we should not forget.
So it is stress acting at a point. Now having said that, we need to now define some
sort of sign convention of the Cauchy stress tensor. So the given sign conventions are the traction
components on the positive plane. So now we have already marked what is a positive plane.
So the traction component on the positive plane acting in the positive direction means the
direction of x y z which is in the positive direction, so is positive. So you have a positive
plane and the traction component is acting in the positive direction, so it is positive.
Similarly, if you have a positive plane and the traction component is acting in
a negative direction, so it is negative. For the negative plane, if the plane is negative
and the traction component is acting in a negative direction, so it is positive. And the final case
is negative plane traction component direction is a positive direction, it is negative. So this is
one sign convention, you can see that numerous sign conventions are available, and uh one may use them at his convenience, but if you follow one sign convention,
you need to follow it throughout. So this is one convenient way of uh defining sign
convention, there are assigned conventions that are available based on movement also, and sometimes
it may be difficult to understand. So this is very easy and very easy to define as well, one example
is given here. So this is the positive x plane, and the stresses acting are sigma xx, sigma
XY and sigma xz. If you consider sigma xx, this is acting on a positive x plane.
And sigma xx is in acting in the positive x direction. So that is why it is positive,
similarly to sigma XY and sigma xz. Now consider the case of the negative x plane, if you consider sigma
XY, this is a negative plane, negative x plane whereas, this is acting in the positive y direction.
So negative plane positive y direction, so it is negative. Similarly, all the stress
component signs can be assigned. So this is the sign convention of the Cauchy stress tensor. So what
is the summary that we have understood till now? There are three normal
components or normal stresses, sigma xx, sigma yy, and sigma oz. You can
see that in this figure, you have sigma x x, sigma yy, and sigma zz, these are acting in
the same direction as that normal. So there are three normal components or normal
stresses sigma xx, sigma yy, sigma zz or it is merely stated as sigma x, sigma
y, sigma z which is a common terminology, which we normally use in mechanics.
There are six shear components or shear stresses to be very specific all indices
were I not equal to j, here it is I equal to, here I not equal to j. So these are shear
components of traction or shear stresses, it is written either in sigma form or in tau
form. Cauchy stress tensor a second-order tensor quantifies the internal force distribution in a
body at a given position and time corresponding to a given deformation.
Why time is important is because we are considering the condition
corresponding to a given deformation. And internal forces, which that gets developed
followed the basic laws of mechanics. Now one particular aspect of why stress
at a point that information is needed is to, define the equilibrium equation. So it is an
application of why you need to know stress at a point. Now stress at a point is
very important to define the equilibrium equation as we have seen in the beginning, you have seen
that certain requirements need to be satisfied like the equilibrium condition,
the compatibility condition, and so on. Now for defining the equilibrium condition, we
need to specify the equilibrium equation. I will not go into the derivation of this equilibrium
equation it is very basic and is mostly seen by most of you. So by considering a given
control volume, the equilibrium equation can be represented as follows. And you can see that the
components of equilibrium equations are the stress tensor components, the only new term is gamma.
Where gamma is a self-weight of the gravity stress which acts in the z-direction or the vertical
direction and to be very specific stresses are in terms of total stresses in this particular
equation, it is invariably necessary to know stress at a point for defining
equilibrium condition. Now based on equilibrium, we can say that tau yx is equal to tau XY, tau
yz is equal to zy and tau zx is equal to tau xz. Therefore, the stress tensor is represented
by six independent stress components, there are nine components in the Cauchy
stress tensor just because of this condition, we have six independent stress components, and
they are three normal stresses, sigma x, sigma y, sigma z, and three shear stresses tau XY, tau
yz and tau Zx, where tau XY is equal to tau yx. So this is what it is. So that is how it boils
down to six independent stress components. So the final summary of what
we learned in this particular lecture is Cauchy stress, sigma is a second-order
tensor. The element of stress tensor represents components of traction acting on three orthogonal
planes according to a given Cartesian coordinate. Sigma I j means j component of traction vector
acting on the ith plane. Stress tensor sigma has three normal stress components and six shear
stress components. But based on equilibrium, there are six independent stresses
three normal and three shear stresses. All the stress components are acting at a
point that is very relevant and which is very important. The components
of sigma depend on the coordinate axis, please note here as such sigma
is not dependent on the coordinate axis, but the components of sigma, I mean to say
sigma x, sigma xy those are the components or the traction vector components, they
are dependent on the coordinate axis. So there is a distinction that needs to be
very clear, one should not get confused with sigma as a whole and the components of sigma.
Sigma as a whole is not dependent on any axis, but the components of sigma keep changing, but
the overall sigma representation of internal force remains the same depending on the reference axis,
and the component’s magnitude value keeps changing. Stress tensor sigma at any point in the body
defines the internal force distribution of a body. So this is all about this particular
lecture, which we will see in the next lecture.
It is an organ
that actively releases hormones and immune system chemicals
called cytokines that can increase your risk
of developing chronic diseases, such as heart disease
and insulin resistance. Meanwhile, stress hormones
affect immune cells in a variety of ways. Initially, they help prepare
to fight invaders and heal after injury, but chronic stress can dampen function
of some immune cells, make you more susceptible to infections,
and slow the rate you heal. Want to live a long life? You may have to curb your chronic stress. That’s because it has even been
associated with shortened telomeres, the shoelace tip ends of chromosomes
that measure a cell’s age. Telomeres cap chromosomes to allow DNA to get copied
every time a cell divides without damaging
the cell’s genetic code, and they shorten with each cell division. When telomeres become too short,
a cell can no longer divide and it dies. As if all that weren’t enough, chronic stress has even more ways
it can sabotage your health, including acne, hair loss, sexual dysfunction, headaches, muscle tension, difficulty concentrating, fatigue, and irritability. So, what does all this mean for you? Your life will always be filled
with stressful situations. But what matters to your brain
and entire body is how you respond to that stress. If you can view those situations
as challenges you can control and master, rather than as insurmountable threats, you will perform better in the short run
and stay healthy in the long run.
For example, the smell of a campfire could evoke the memory of being trapped
in a burning house. For someone with PTSD, that memory activates the same
neurochemical cascade as the original event. That then stirs up the same feelings
of panic and helplessness as if they’re experiencing
the trauma all over again. Trying to avoid these triggers,
which are sometimes unpredictable, can lead to isolation. That can leave people feeling invalidated, ignored, or misunderstood like a pause button has been
pushed on their lives while the rest of the world
continues around them. But, there are options. If you think you might
be suffering from PTSD, the first step is an evaluation
with a mental health professional who can direct you toward
the many resources available. Psychotherapy can
be very effective for PTSD, helping patients better
understand their triggers. And certain medications
can make symptoms more manageable, as can self-care practices,
like mindfulness and regular exercise. What if you notice signs of PTSD
in a friend or family member? Social support, acceptance, and
empathy are key to helping and recovery. Let them know you believe their
account of what they’re experiencing, and that you don’t blame them
for their reactions. If they’re open to it, encourage them to seek evaluation
and treatment. PTSD has been called “the hidden wound” because it comes
without outward physical signs. But even if it’s an invisible disorder,
it doesn’t have to be a silent one.
