Video summary
The video features Dr. Nasser Karma Medicic, a surgeon-in-training based in London, who shares his comprehensive approach to maintaining physical and mental health while working long hours at a desk. He emphasizes that ergonomics is the cornerstone of a healthy workspace, directly influencing posture and preventing strain on the wrists, shoulders, neck, and back. Central to this strategy is the use of an adjustable standing desk, which allows users to easily switch between sitting and standing positions throughout the day. This flexibility helps mitigate the fatigue associated with prolonged static postures; Dr. Nasser personally alternates between one hour of sitting and one hour of standing to keep his body active and reduce aches in his lower back and neck.
To optimize physical comfort, he details specific adjustments for every part of the workstation. A proper chair must be height-adjustable to ensure knees are at a 90-degree angle with full-length lumbar support, while the desk should provide ample depth—ideally around 60 centimeters—to allow monitors to sit far enough away to prevent eye strain and neck extension. The monitor itself needs to be positioned so that its top edge is level with or slightly below eye line, keeping the head in a neutral position without looking up or down excessively. Additionally, keyboards should not force wrists into an extended angle, and peripherals like mice and cups of coffee must remain within easy reach to avoid unnecessary stretching. Small tweaks, such as increasing mouse sensitivity or using soft floor mats for feet, further contribute to reducing muscle stress during long work sessions.
Beyond physical setup, the video highlights the critical importance of movement breaks and mental well-being in a home office environment. Dr. Nasser utilizes an alarm that rings every 55 minutes to remind him to check his posture, stretch specific areas like the neck and spine, and walk away from the desk for hydration or coffee. He advocates for eye care practices such as following the 20-20-20 rule—looking at something distant every twenty minutes—and using blue light filters to protect against digital strain and sleep disruption. Ultimately, he argues that a comfortable, organized, and spacious workspace significantly boosts mental health by fostering happiness and focus rather than resentment. By combining these ergonomic principles with regular movement and a tidy environment, professionals can sustainably work for extended periods without compromising their physical or emotional well-being.

What is up guys? Karma medicic here and
welcome back to another dose. If you're
new to the channel, my name is Nasser
and I'm a doctor and now surgeon in
training living and working in London.
And today I want to talk to you all
about my desk setup. We're going to be
talking ergonomics, posture, eye care,
mental health, and more. So make sure
you stay till the end to make sure that
you're staying healthy whilst studying
or working from your desk. This video is
sponsored by Vernal. They're the ones
who sent me this beautiful desk over
here. And you'll find all details about
the desk, including a discount code,
YTKM, down in the description below, and
I'll talk about them later on in this
video. But this video is about how to
stay healthy whilst working at your
desk. So, let's get straight into the
most important part of your desk setup,
ergonomics. The ergonomics of your desk
is central to staying healthy, and it
directly influences your posture. You
know, no matter how fancy your desk
setup is, something like this, if it's
not set up correctly, then it might be
doing more harm than good for different
parts of your body, like your wrist,
your shoulders, your neck, and your
back. Now, let's start with the
foundations of ergonomics. Starting with
the floor and working all the way up
until our eye level. Now, the first
thing that you want is a comfortable
chair. Now, these can come in all shapes
and sizes, but the important thing is
that it is height adjustable so that
your knee can be at a 90° angle or a
level of flexion when your foot is
making contact with the floor. Now, you
can also get chairs that have lumbar
spine support and all kinds of
adjustments and things to inflate and
deflate. And if that's an option for
you, I'd say more customization is
better. But for me personally, the most
important thing is a chair that is
height adjustable and has a full length
back rest. And hopefully your desk is
kind of like this where you've got
plenty of room underneath to be able to
stretch your legs and not hit your knees
up against the frame of the desk itself.
Now coming up to the elbows, you want
these to be naturally rested at about a
90° level or a little bit further down
than that. Just something that's
comfortable and relaxed. What you
definitely don't want is for your elbows
to be raised so that your shoulders are
in this kind of exaggerated position
where they're up and causing lots of
tension in your neck. Now, what I find
really helps achieve this is having a
standing desk because you can adjust the
height of the table and then let gravity
do the work to pull your elbows down
into a nice and relaxed position. Now,
with standing desks like this, you can
raise and lower the height using a small
control panel on the side, which even
has memory buttons specific to the
heights that you've set, which are
optimized for your seated or standing
position. or even if you have a partner
or other people using the desk, they can
have their own memory preset, which is
what we have going on here. And that
makes sure that the desk returns to its
optimized kind of resting position for
you, whether you're standing or sitting.
Now, probably one of the best pieces of
advice I can give you in this video is
to get yourself a monitor or a screen
with a wireless keyboard and mouse. This
just unlocks an infinitely more
comfortable desk experience over simply
placing your laptop on the table in
front of you where it's often too close
to your body and you need to lean in and
scrunch over to get your eye level down
to the level of the screen, putting lots
of additional strain on your neck and
your shoulders. Now, your monitor should
be set at about an arm's length away,
kind of like this, because being too
close can cause a lot of eye strain,
which we'll talk about later in the eye
health part of this video. And also if
your monitor is too far, then it causes
you to lean forward to kind of look into
the content of the screen or bring it
closer to you, which again puts you in
this really bad set of posture where
you're leaning forward, shoulders are
rolled, and your neck is extended. This
is especially important for people like
me who have really large monitors where
that poor posture can often be
exaggerated and lead to significant neck
and upper back pain. Now, this desk is
plenty deep to give me enough space to
put the monitor far away. I think it's
at about 60 cm or so, but you can get
them even up to 80 cm, which is even
deeper. And this is something I'd
strongly encourage you to think about
when purchasing your own desk. Now, when
talking about the height of the monitor,
it should be raised so that the top part
or the top kind of two to three
centimeters or so are almost at eye
level or within your eye level. Now, the
reason for this is that you want your
kind of resting neck position to be
looking at the monitor and you don't
have to look up to look at your monitor,
which causes loads of strain and pain in
the neck. And at the same time, you also
don't want to be looking down cuz then
you're using a lot of your neck muscles
in order to maintain that position. You
want to be in a neutral neck position
where your eye level is at approximately
the top of the monitor. Now, your
keyboard and mouse on the desk should be
far enough into the desk so that you can
rest some of your wrist and forearm on
the desk itself and not have them
hovering in the air, which causes again
a lot of muscle stress to be able to
hold them in that position. You also
don't want them to be too close to you
that you're kind of tucked in with your
elbows like this, which can also be
straining. So, yes, the advice is not
too far, but not too close. Find a place
that's comfortable for you. The actual
height of your keyboard shouldn't be so
high that you have to extend your wrist
like this in order to type on it. Some
of these keyboards have a really thick
base and can be quite high, causing a
lot of pain when you take this position.
If your keyboard is like that, you can
always get a wrist rest or something
nice and soft to put underneath your
wrist to hold them in a more neutral
position or kind of straight when you're
doing your typing and your mouse moving.
Now, there's all kinds of products that
you can find online to help deal with
this, mostly cushions for your wrist to
rest on. So, have a look if this is
something that's been bothering you.
Another thing to say is to keep your
peripherals, you know, your mouse, your
keyboard, your cup of coffee or whatever
within reach. You don't want to be
having to stretch over and extending
yourself every time you want to use your
mouse on the desk. You want everything
to be kind of close. You know, I want a
cup of coffee. Here it is. I want to
type on my keyboard. It's right there. I
want to use my mouse. It's right there.
Don't put things far away from you. Set
everything up on your desk so that it's
within a comfortable reach. Another
relatively small but I think useful tip
is that you can turn up the sensitivity
of your mouse so that with smaller
movements, physical movements on the
desk, your mouse cursor moves a much
larger distance. And this prevents you
from having to do kind of this when
you're trying to move across the screen
with the mouse. Instead, you can just
kind of go a little bit left, a little
bit right, and your mouse moves quite a
lot. Then there's the small things that
you can do like having a soft surface
for your feet to rest on like a carpet
or perhaps a supportive floor mat or
cushioned mat. that can take a bit of
the pressure off of your feet, which
again takes the pressure off your knees
and makes it a bit more comfortable to
sit at your desk for long periods of
time. Now, for me personally, I've had
standing desks for the last 7 years or
so, or 8 years that I've been living
here in the UK, and personally, they're
absolutely necessary because they unlock
a completely different way of working or
studying from home. The best part of
this is that you can quickly switch
between these two positions. And for me
personally, when I sit at a desk for a
long period of time, I get a lot of
aches all over my body, in my neck, in
my lower back. And moving into a
standing position for an hour, getting
that change, moving my legs around, and
then coming back to a seated position is
the only reason that I can, you know,
sit down and work for such long periods
of time like I do in all of my study
with me videos. Having a motorized
standing desk where the table lifts and
lowers automatically is, you know, even
better. I used to have a manual one that
I would have to crank and that kind of
increased the activation energy that I
would need in order to move it into the
standing position. So, I would do it
less often. But with a desk like this
where you just press a button and it
simply lifts or lowers really quickly
and easily, super stable at the top, it
makes it a very easy decision for me to
switch between the two modes. I usually
alternate between an hour of sitting and
an hour of standing, and it makes those
long work sessions so much more doable.
Now, regarding ergonomics, when standing
at your desk, a lot of the same things
that we talked about still apply. You
still want your elbows at about 90°. You
want to match the height of the monitor
to meet you at eye level. And again, you
can move the keyboard and mouse and
adjust them as you need to keep them
within reach. Now, posture is something
that is all too often ignored. And if
you don't pay serious attention to it,
it can easily slip and lead to all kinds
of muscularkeeletal problems. I'm
definitely guilty of this, and so you
know, this section of the video is just
as much for me as it is for you
watching. If you have good posture, then
it helps you keep your back, knees,
shoulders, wrists, and neck in check.
When sitting down, your feet should be
flat on the floor in their neutral
position, not raised in plantar flexion,
which is like this or in the other way,
dorsif flexion like that, just rested
nice and neutral on the floor. You
should avoid crossing your legs as much
as possible cuz this puts pressure on
all the different structures in the
lower limb or in the leg like your
arteries, your veins, your nerves. And
I'm sure you've all had that feeling
where you sit down for some period of
time and then you have a dead leg with
your pins and needles. You want to try
and avoid that. Keep yourself in a nice
rested position. Try not to cross too
often or sit on your leg for a long
period of time. Another really important
thing is that you want to avoid leaning
into your screen. And I'm particularly
bad at this. I think because I just get
tired after sitting down or standing for
long periods of time, particularly my
neck, and I kind of slump into this
forward position. Now, in this position,
your neck is outside of its natural
alignment with the spine, which is kind
of like a top down string. And instead,
your muscles are using a lot of energy
and straining and tensing in order to
keep the neck in this position. Because
if you were to relax, you would just
fall like this, right? So, keeping your
neck up like this forward is actually
quite straining, especially over long
periods of time. So, make sure you kind
of always revert back to your natural
neutral seated position. Now, if you
have a full-length chair where you can
rest your back and your head, I
personally find it quite comfortable to
rest my head slightly up against the
headrest, which I think relieves a
little bit of tension and stress up in
my neck muscles. Now, a great tip that I
once heard from someone on how to remind
yourself to get into a good posture is
to imagine that somebody has a string
kind of attached to the very top of your
head and they're pulling you up on that
string from the top of your head. And
that helps me get into this kind of
relaxed neutral position, which is where
my posture is much better than me just
slumped over or leaning into my screen.
Okay, now let's talk about shoulders.
Please, please, please relax your
shoulders. Okay, keep them nice and
down. Roll them outwards. So, that's
external rotation like this, not
rounded. and internally rotated like
this. Okay, you've probably seen people
who spend too long at their computer
like me have rounded shoulders where
they're kind of hunched down looking
like this. Shoulders nice and relaxed
down rounded. Okay, and externally
rotated like this. Just relaxed. Okay,
none of this. This is the worst for
posture. Now, I find this position
extremely easy to do when I'm standing
because I feel like gravity just
naturally pulls my shoulders down and
makes it a bit easier, but a little bit
harder when sitting. So, it's something
that I need to constantly remind myself
to do. Now again, when it comes to
posture while standing, most of what we
talked about before still applies, but
one key thing to take note of is your
positioning of the feet when standing.
You want to make sure that these aren't
too close together. You can have them a
little bit further apart to kind of
evenly distribute your weight across
both legs. Try and engage your core
again so you're not kind of leaning
backwards or leaning forwards. And avoid
locking your knees entirely. You can
keep them a little bit flexed. You can
move around going from one leg to the
other. Stretch your knees, you know,
lift your legs up a little bit every now
and again. get the blood flow going down
there is that you don't have blood
pooling towards your feet. Just move
around a little bit. Another advantage
of having a standing desk is you can
kind of alter your movement and move
around a little bit. Now, if you have
one of those walking treadmills or anti-
fatigue mats, this would be a great
place to use them. Having any kind of
movement in the legs while you're
standing can really help with
circulation and prevent blood from
pooling down by the ankles. This can
reduce fatigue and can help you stay
working or studying at your desk for
longer periods of time. Now, one tip
that I find incredibly helpful to
remember all of these different aspects
of my posture is that I have an alarm on
my phone or on an app on my computer
that rings every 55 minutes. And it's
just a reminder for me to check, am I
slouching down into my chair? Am I
leaning forward? Do I need to sit
upright a little bit more? Maybe adjust
some of the peripherals on my desk. It
just acts as a little, you know, Nasser,
remember to check your posture. You're
here for a long time. You need to be
able to stay healthy and stay here in a
comfortable way. Now that 55minut
reminder is also a great excuse for me
to get up and move away from my desk,
get a glass of water, a cup of coffee,
whatever. And also a reminder to do some
gentle exercises and movements which
we'll talk about in the next section.
Now sitting at your desk all day is
tiring. And if you're anything like me,
over time you start to get really stiff
and tense sitting at your desk,
particularly in your lower back, your
shoulders, and your neck. And this makes
it all the more important to introduce
movement and stretching into your
routine when you're working or studying
from your standing desk all day at home.
So, like I said, I have this timer that
rings every 55 minutes that I've spent
at my desk, and it's a reminder for me
to do all of these things. Now, the
stretches and movements that I do when
my timer rings changes all the time. I
don't always do the same thing. Just
depends on how I'm feeling that day. But
here are a few examples of the different
kinds of movements and stretches that
you can introduce into your studying or
working routine, which are really quick
and easy to do, but can make a big
difference to your comfort at your desk.
So, I think it's really important to
stretch out your neck and you can move
it from side to side applying a bit of
gentle pressure with your hands. If you
want to get that extra big stretch in,
you can rotate your neck looking towards
the left and looking towards the right.
You can move your neck up and down
having your chin touch your chest and
also raising up your neck to look up
towards the sky and do gentle neck rolls
as well. You can do them half neck rolls
like 180 degrees or full neck rolls in a
360 degree motion. Now for your spine, I
personally find it really really
relieving to crack my back and crack my
spine, but I try and avoid it as much as
possible and instead replace it with
movements like this. So you can flex or
bend your spine moving left or right to
get a bit of that big stretch into the
big muscles of your upper back and side.
Especially if I'm standing and studying,
I will periodically stretch my legs. So
you can stretch your hamstrings, which
are your hip extensors, by doing this.
You can stretch your quadriceps or your
hip flexors by doing this. And that
really helps release the tension down in
my lower legs. And like I talked about
before, prevents the pooling of blood
around the ankles and the feet that you
can get from standing for long periods
of time. Now, like I said before, you
don't have to do all of these stretches.
Just introduce some movement and
stretching into your routine so that you
prevent yourself from becoming stiff and
can stay working at your desk for longer
periods of time. And then again, this
timer is a great excuse to step away
from your desk. Like we said, even if
it's for something as simple as grabbing
a cup of coffee or a glass of water,
checking in on your girlfriend or
whatever it is, just to get a bit of
movement and change of position and
posture away from your desk. Now, let's
talk about something that I'm sure we've
all long forgotten about, which is eye
care. But seriously, we spend hours and
hours staring at screens during our day.
Whether it's, you know, these big
monitors here or our phones, our TVs,
computers, it's not great. But here are
a few different things that you can do
to protect your eyes and take care of
them in the long run. First of all, if
your computer or your monitor has
something like a true tone setting, make
sure you turn it on. It adjusts the
colors, the brightness, and the
intensity of the display to match your
ambient lighting in the room so that the
screen is more natural and comfortable
for your eyes. This is particularly
important at nighttime when your ambient
uh environment is quite dark and you can
have your bright white screen blasting
all of these colors straight into your
eyes. You can turn that on and it kind
of adjusts things to make it more
natural. Second, and very importantly,
is every now and again you should try
and look at something that is far away
from your screen. When you're focused on
an object or something that's in front
of your face, your eyes do something
called accommodation, which is adjusting
of the muscles of the eye so that they
can focus on the thing that's in front
of you and bring that object into focus.
Now, this is actually really tiring. And
if you want to get a sense for just how
tiring this is, you can do an
exaggerated version of this, which is
trying to focus on something very close
to your eyes. If you put your finger
right in front of your eyes and focus on
it for just 5 or 10 seconds, you'll
realize just how much your eye muscles
are straining in order to keep that in
focus. Now, your eyes are actually doing
something very similar when you're
looking at a monitor in front of you.
It's just that they're a little bit far
away, but they are still tensing and
focusing on that object nonetheless. And
so in order to break that and relieve
your eyes of that tension, you need to
look at something that's further away,
far away from what's directly in front
of you. This gives the muscles in your
eyes a chance to rest. It allows them to
relax, kind of reset, and then you can
go back to staring at something that's a
bit closer. And a very common rule of
thumb or something to help you remember
about this is the 20 2020 rule, which
says that you should look at something
that's approximately 20 ft away for 20
seconds every 20 minutes. Now,
admittedly, I don't do this. What I do
is every hour when that timer rings and
I do my different stretches and
movements, I walk away from my desk to
get something that also introduces me to
look at something that's a bit further
away. But if you have a window, you
know, with a nice view behind your desk
or if you can go and look at something
that's further away, that's particularly
helpful. Another thing that you can do
is get blue light glasses or you can
download softwares for your computer
that are blue light filters, something
like Flux. And this reduces the amount
of blue light exposure that is coming to
your eyes from your screens. Now, again,
this is especially important in the
evening and nighttime because blue light
from the sun naturally is what tells
your body to stay awake and what
stimulates you throughout the day. So,
if you're looking at your screens and
receiving a lot of blue light,
especially at night, it can disrupt your
body's natural circadian rhythm, which
makes it harder to fall asleep. So, if
you've got those white bright hospital
lights, you know, replace them with
something that's a little bit more like
this, a little bit warmer, yellower. Uh
research has shown that it it can help
you relax and improve your eye strain.
Now everything that we've talked about
so far in this video is, you know,
really helpful from a practical point of
view. But from a mental health and a
sanity point of view, you know, having a
comfortable working environment can be
the difference between sitting or
standing at your desk working all day in
a happy mood or being the place or area
that you go to which you really resent
and you don't enjoy being there and
keeps you uncomfortable for 8 hours or
more depending on how long your working
day is. And it's easy to forget your
mental health as part of, you know, your
working environment when standing or
sitting at your desk. And it's just as
important as your physical posture,
especially when you're here for long
periods of time. I've just gone through
a multi-month studying period when I was
preparing for a big surgical exam. And
you know, making sure that my mental
health was in check throughout that
entire time was really important to me.
In fact, without keeping my mental
health in check, I wouldn't have been
able to do the physical amount of
studying that was needed to get done.
And personally for me, I've always found
that having a comfortable and happy
working environment leads to me being
able to study more, be more rested, be
more focused, and be more energized in
the work that I'm doing. This kind of
spacious, cozy, organized, and neat desk
is, you know, at the core of my
happiness when I sit down here to work.
And really, it makes a huge difference.
Like I said, it helps me keep relaxed,
focused, and motivated to actually work
here and get things done as opposed to
being a place that I just kind of resent
going to and don't want to be in. I want
to give a really big thank you to Vernal
who, like I said, sent me this desk and
have allowed me to build such a
beautiful desk setup that fits
everything that I want and I feel has
really improved my mental health and
happiness whilst working over here for
such long periods of time. Building the
desk was extremely easy. It came with
pre-installed nuts everywhere. So, all I
had to do was put the legs together,
attach the legs to the desk, and then
flip the whole thing over, and I was
basically done. If you're particularly
interested in my desk, this is a solid
wood walnut desk that measures 160 cm in
length by 80 cm in depth. But Veral has
a bunch of different desk sizes and
materials on their website that you can
look at to find the desk that best suits
you. Personally, I love having a big big
big desk. This way I have, you know,
space to put everything that I want on
it in a neat way where it doesn't look
cluttered. I've even got this desk shelf
over here that gives me kind of two
levels of separation and storage so I
can put things underneath. And you know,
having a big desk for me is a big part
of my like mental health and happiness
when studying, just that I have a
comfortable and open space that I can
work in. Now, if you didn't know, I'm a
pretty tall guy. So, being able to raise
this desk to a height that is tall
enough for me to be able to rest my
elbows comfortably is really, really
great. With my old desk, I felt that I
couldn't really get it high enough. So,
the fact that this one raises as much as
I need it to is really important to me.
And having the memory buttons on that
control panel on the side is just a game
changer, making it super easy to switch
between the standing and sitting
position, which is really important to
encourage me to do that multiple times
in a big working session. And that's
what allows me to stay at my desk
studying or working for so long. It's
the fact that I can change my posture. I
can change my position, and it keeps me
comfortable for much longer periods of
time. The desk is also rock steady at
its maximum height, which is great cuz
it means I don't have to worry about
knocking over or spilling my coffee or
water glass while studying. And like I
said, for me, being happy at my desk
means having a neat and organized desk.
I love that over here everything has its
little place. You know, I've got my
catch all for my wallet, my AirPods, my
watch, my keys, things like that. My
computer sits neatly under here. I can
pull out this shelf over here, which has
my notepads and stuff. I've got a little
charging station back over there for my
phone and things, speakers, camera,
keyboard, and everything on this mat.
All the rest of it, for me, having this
neat and organized environment just
really helps me be comfortable and happy
at my desk. And part of this neatness
and organization is that I've gone to
great lengths to make sure that there
are no cables visible on the desk. I
mean, maybe you'll find one or two, but
just ignore them. I'll show you the
belly of the beast underneath so that
you can see how I've achieved all of
this. Vernal has a cable management kit
that includes things like cable ties. It
has the cable tray, these cable
organizers that help keep everything
kind of neatly tucked away underneath
the desk. So when you walk into the
office or when you're sitting or
standing working at this desk, you don't
see any of those cables and everything
just looks like magic in my opinion. At
the end of the day, as a doctor and
training surgeon, I spend hours and
hours studying and working here. And
it's really important for me that my
desk is organized, comfortable, and big
enough to have everything that I need on
it like this. Overall, I really feel
like I've managed to build the desk
setup of my dreams, which has everything
that I could possibly ever want on it
and is organized in the way that helps
me stay comfortable working and studying
here for really long periods of time.
And that brings us to the end of this
video. I really hope that you learned at
least one new thing about how you can
stay healthy whilst working or studying
at your desk for long periods of time.
