- Corgiland, Reddit. If I sweat a lot, do I pee less? Yes, your urine becomes more concentrated cuz you have less fluid to eliminate. So that's why when you sweat you should always be drinking more water to make up for the losses
that occur when you sweat. Also, remember when you have a fever, you also lose fluids more rapidly and as a result, you should
be drinking more fluids. What would happen if all your bones suddenly teleported out of you? You'd become a bag. You'd just be a bag. And the handle would be like your mouth cuz teeth are not bones so you
could still grab by the teeth and the teeth are like the handle. Clearly I've watched one
too many horror movies. Is it possible to get food PTSD? I had to take a cinnamon
apple flavored medicine for a flu two months ago, I don't know what medicine that is and I'm pretty sure it didn't do anything. Sorry to say. A lot of over-the-counter medications are unnecessary for flu
and it made me throw up. Clearly it didn't do well for you either. Ever since if I smell or see
something cinnamon flavored I feel nauseous for the rest of the day. I wouldn't necessarily call
this PTSD, medically speaking. But colloquially speaking, meaning just like in average words, I understand what you mean by PTSD because it's an experience
that is bringing back a memory but it's really more of your
olfactory region of your brain being very intimately tied to the memory portion of your brain. And as a result, that nasal
smell that you experience transmits to the memory, makes
you remember how you feel. Is it unhealthy to eat your boogers or does it help boost your immunity? I would say it is unnecessary
and I would say it's unhealthy because odds are if you're
eating your boogers, you're probably doing
it with dirty fingers and your digits are
potentially the dirtiest, highest bacteria count
portion of your body. So don't eat your boogers. Is it possible I just
became lactose intolerant later in life? I was drinking a frappe and then I had intense abdominal pain and an urge to use the bathroom and it's happened every
time I've drank milk since. This has never happened before. Not unusual to develop or lose allergies and intolerances throughout your life. Sometimes they can even be temporary, due to some sort of illness,
sometimes viral related. Don't know if that's exactly
what's happening to you but definitely worthwhile to
talk to a doctor about it. I really wanna start exercising more but I find going to the
gym or running so boring. Is there a more fun
exercise you'd recommend? Yes, first of all, try all those exercises that you found boring, with a friend. That goes a long way. Try taking a boxing class
where they teach you techniques and you're punching the bag and you're learning how to
move around with the bag. Try rock climbing, try bouldering, try stepping outside of your comfort zone and taking a dance class. Any type of movement that
makes your heart rate go up is considered exercise. So have fun with it. Andrea, from YouTube. I'm on a long wait list to
be seen by a new therapist. Is there any self-help things
I can do in the meantime? Okay, journaling, very beneficial. Three good things at
night, very beneficial. Like literally writing three good things for a period of two weeks
can help reshape your mind into how you're thinking
about your anxieties and the good things that happen
that we oftentimes overlook as a survival mechanism
that our brain does. But the best thing to do is something that I
recommend to all patients called bibliotherapy. Read a book called "Feeling
Good or Feeling Great" by Dr. David Burns and
do some of the exercises in those books, I think
it's a great way to start if obviously, it ever becomes too, the symptoms become so severe that you feel like you're losing control, that's a 9-1-1 call. But otherwise I think
bibliotherapy for mild symptoms is a great place to start. Gavin H from YouTube. If I drink a glass of water how long will it take until I pee it out? What about food? If I eat a big meal, how long
does it take to come out? Does any of it come
out in different times? There's a lot of variability here because if you consume water and you are already well hydrated, so it's like excess water,
it'll come out faster. If you consume water and then
a caffeine based substance, like tea or coffee that
acts as a diuretic, it will also come out faster. Food, so many variabilities. Is there fiber in the food? How much did you eat beforehand? At what time of the day did you eat? How healthy is your digestive system? For example, my patients
that have diabetes can develop something known as diabetes related gastroparesis. The natural waves called peristalsis that keep the food moving in your gut actually get sort of thrown out of whack and as a result, therefore
food doesn't move as well throughout your gut so you feel bloated, you develop nausea, vomiting. So as you can see Gavin,
a lot of variability here so I don't want to give
you a surefire answer. Chassy Red, YouTube. My mom always told me the
best way to get rid of hiccups is for someone to scare you. Is she right? I actually don't think that's a good way and remember there's
actually two nerves involved when it comes to hiccups
cuz that's happening as a result of a diaphragmatic spasm. The diaphragm's, that giant
muscle that sits below the lungs that pulls the lungs down to breathe and then pushes up and relaxes and then helps the lungs exhale. So in this scenario you
have the vagus nerve interacting with the phrenic nerve, creating this diaphragmatic spasm. And what I found to work best for me and so many of my
patients is a little spoon of granulated sugar. There's also some really
good evidence-based methods for breathing into a paper bag to increase carbon dioxide levels or like taking a breath in, holding, taking another quick deep
breath in without exhaling. And then another time one more time. There's actually a prescription medicine called Thorazine that you
can use to control hiccups when they're gone on
for days on days on days and you can't control them
with the natural methods that we just discussed. But we really reserve
those for complex cases and they do happen with
certain chemotherapy agents and surgical situations that I've seen in my patients in the past. Is a stinky belly button
a healthy belly button? I'm gonna go ahead and venture to say, with the exception of your
excrement, AKA vomit, poop, nothing should really
smell bad on your body. Your nose is acting as a chemical receptor to tell you that there's something off. So for example, if your belly button starts creating a foul smell, odds are there's some kind of
bacteria and or fungus having a little nightclub
party in there with DJ- (vinyl screeching) what's the thing you pull
outta your belly button called? - [Sam] Lint? - DJ lint spinning - [Sam] Lint Bizkit? - Lint Bizkit. Cloud Enthusiast, Reddit. Okay, but like how do doctors learn CPR? Do you have to go to a normal
CPR class like normal people? Is there just one day in med
school where they teach you? Is there a whole semester
long course called CPR 101? That would be epic. I would go to a chest
compressions yearlong course. You do something called BLS
and while pretty much anyone can go to this, as long as you sign up, most medical schools have a
day where all the students are scheduled to go through this. And then usually what
we also do as physicians is called ACLS training, which
is the next step after BLS. Cause that's basic life support. What to do if the heart full on stops and you need to intervene. You need to give medications
if the heart is beating so fast or so slow, how to
intervene, things to check. This is my BLS provider card here that you get when you complete the course. My ACLS provider card. Look at that, American Heart Association. Did you see my kiosk? If you haven't, check it out. If someone goes through a
horrible accident, loses a limb will that limb go stiff from rigor mortis or does that only happen
to the whole body? Oh, that's a good question. I have no idea. I have not experienced enough traumas in my medical education
to know if that's true. Mosh pit, YouTube. Why don't we ever sneeze
while we're asleep? Why does it only happen when we're awake? It probably can happen to
some who are in light sleep. But in deep sleep, these types of reflexes are probably suspended. And I still think if
there's enough stimulation of the airway, you probably
could sneeze out of asleep. But you're awake at that
point so you're not asleep. Tricky, tricky questions. Like what came first,
the chicken or the egg? The sneeze or the sleep? Hey Dr. Mike, do I need to eat the actual fruits and vegetables or can I just take the vitamins that have the same ingredients that way I don't have to
waste calories on the veggies? No, eat the veggies. What vitamin supplements are are the things that we've so far learned that is the healthy part
of fruits and vegetables. It doesn't mean that's the only part. There's so many other things
within fruits and vegetables like phytonutrients that we
don't fully yet understand or have fully yet explored. And also there's other benefits to eating fruits and vegetables
outside of the mineral and vitamin content like fiber, which supplements don't contain. I've had a hernia so I've
assumed for a number of years it only hurts when I press on it. Is there any reason I
should go to the doctor to treat this or can I just go on doing about not doing anything
about it for another decade? I'm gonna talk about
an inguinal hernia now because there are other types of hernias and they all carry different risks. But if we're talking
about an abdominal hernia or abdominal wall hernia,
what ends up happening is you create a risk for something known as
bowel incarceration. Your intestines, AKA your gut, actually can poke through this hole because a hernia is an
opening in the abdominal wall. And if you have an opening
and a piece of the intestine sticks out of that wall and then it starts getting choked out because of its positioning
and when I say choked out, means the pressure around
it due to inflammation or its position starts
increasing so much pressure that it cuts off circulation
and starts strangulating that bowel, that's a surgical emergency because that bowel is literally dying and needs to be rescued. So the reason why we
proactively operate on hernias is to decrease the
likelihood of that happening. And what's interesting about hernias is that the larger the hole,
meaning the bigger the hernia, the less likelihood that an incarceration or strangulation of the
bowel would actually happen. So it's the smaller ones
that don't look as bad that actually tend to be more problematic. When I've got a cold and
I'm blowing my nose a lot, my snot changes color,
sometimes it's clear. sometimes it's yellow,
what's the difference? It's about the cells that
are present inside your snot. A lot of people make the assumption that if their snot is a certain color, they know whether or not it's a bacterial or viral infection. That's not always true
because for example, many people say if your snot is green that means you have a bacterial infection. That is true in some cases,
but at the same time, sometimes your snot can start being clear and then towards the end
of your viral illness, change color to something
that's yellow or green and still be viral and not be bacterial. So I don't use that as the
sole judge of what's going on. It needs to be thought
about in a whole spectrum of whether you're having
bacterial like symptoms like fever, sinus tenderness
and then the color of the snot can be one of those variables, but I wouldn't use it as the
sole discriminatory point for making a diagnosis. Why does Vick's Vapo Rub make... I love that you said Vapo Rub. - Vapo Rub. - I only got a B in geography. - Vapo Rub. - My girlfriend just dumped me. - Vapo Rub. - By the way, the podcast
with Stephen He is a banger and if you haven't

you're missing out. Check it out cuz everyone's loving it. Why does Vick's Vapo Rub make my cough go away
faster than cough medicine? What is that stuff? I'm pretty sure Vicks
VapoRub is just menthol. Menthol is interesting cuz
what it can do is create a cooling sensation
which which feels good. Maybe creates some opening
and dilation of the airway on a superficial level. But in reality, cough
medicine doesn't really work. I really don't use cough medicine in the huge majority of my patients unless I'm treating
the source of the cough like acid reflux, postnasal drip, asthma where I can give them an inhaler to bronchodilate the spasm away. I like using a steam inhaler
for when I have a cough. It really feels like it opens things up. Why is it so much harder
to fall asleep as an adult than it is a kid? We have a higher sleep need as children, meaning we sleep for longer
hours and as we get older the need for deep sleep decreases. The amount of sleep a one-year-old needs versus 101 year old needs
is drastically different. And something to also think about that the number of REM hours of sleep is difficult to maintain the older we get. And I'm sure anxiety is
a component there too but that's not one that's
routinely taught to us. ConnieTsai. How do I my nostrils before bed? It always feels like one
of them is totally stuffed. If I have a patient whose
nose is stuffy quite often, I would try my best to narrow down to the most common diagnosis
and try some medications like nasal sprays. I like using nasal saline to
clear out the nasal passageways cuz it's a benign thing to do. Doesn't have real big side effects. And then there's other
things that we could do like histamine nasal sprays,
steroidal nasal sprays and if those don't work, I really like to get
an ear nose and throat specialist on board to
do a fiber optic exam where they put a little camera
in to check the anatomy. There's different parts
of the nasal passageways that can be operated on
where I've seen patients get good results and then some patients that have overdone it. So make sure that when
you do meet with an ENT, talk about the risks and benefits for your specific condition. Also, another cool tip here is throw a humidifier in your room. Sometimes just moistening the
mucus membranes helps a lot. And also staying well
hydrated thins out mucus, makes it easier to breathe as well. They say humans use only
10% of their brains. Do smarter people use
more of their brains? I think this is a complete myth. I don't even have evidence to say it but I think I've looked
this up in the past and I think it's a complete myth. Is there a health benefit to
wearing those barefoot shoes with the toes? In some instances there might be, but they're also significant risks. We've seen people develop stress fractures because they have very thin padding, but then some people
develop stronger shins. They have pros and cons, weigh them for your own individual decision. I've never really seen an
instance where I'm like, "Yeah, that was the way to go." I think if you're interested
in barefoot training, doing it on sand is
probably the way to go. But doing it on hard concrete is just gonna create so much shock that will go into your knees and hips, that long term, I don't
find it really beneficial. Is marching band a sport? Does it raise your blood pressure? Your pulse? Does it make you sweat? Is it competitive? If you answered yes to those
