Do Jaw Trainers Actually Work? | Responding To Comments

i'm answering the most complicated and maybe some of the funniest questions that sam picked out for me are bones wet or dry they have blood vessels inside them they're blood there's blood so they're wet actually they're spongy and if something's spongy it's more likely to be wet than not does being slapped actually wake you up or is that a cartoon thing it absolutely does wake you up you know what wakes you up more than a slap a sternal rub we actually do that in the hospital to our patients the sternum is a bone if you rub it very aggressively like that it'll wake a patient up that's how we check if they're actually unconscious or awake or just asleep what is the leg version of your armpit called uh it has a name now pop a teal area see sometimes even doctors forget terms it's the palpateal area palpation fossa is it dangerous to eat apple stems my friend eats the entire apple and i'm afraid she's gonna hurt herself i've never heard of apple stems being dangerous to eat i know i really don't want to eat the seeds what's wrong with the seeds i'm pretty sure they contain some kind of anti-phytonutrient or something let's see apple seeds can be indeed poisonous from britannica.com but it takes quite a few of them to kill you and they have to be crushed adult would need to eat 150 to several thousand to be at the risk of cyanide poisoning wow interesting the more you know is it true that if you step on crack you break your mama's back or if you step on a line break your daddy's spine i don't know what kind of bondage question this is but no i don't know why there's drugs mentioned in this you shouldn't be stepping on crack because it's illegal you shouldn't be stepping on a line break i don't know what that means do you know where what this is from no oh how funny it's when you walk on the sidewalk it's a game kids play step on a crack you break your mother's back whoa this is some american stuff yeah i grew up here you see while these guys were playing that game i was learning arithmetic see my daddy was breaking my spine if i didn't get the arithmetic right barely alive hey dr mike what do you think about developing birth control for men absolutely necessary uh there are already some options out there so we need to do more of that do you ever use your medical training on non-humans like bear absolutely joshua whenever bear is sick i'm trying to figure out what's wrong with him in the same way that i do with the human even when i go to the vet i ask very pointed questions and they're like are you in healthcare i'm like i'm a family doctor and bear's family so you better take care of him like family get me april should i put on sunscreen before or after i apply my makeup ah that's a really good question well if we take this logically you want to apply the sunscreen directly to your skin so that it gets absorbed and does its job protecting your body from uv rays then you could put the makeup on on top of the sunscreen but the sunscreen has to come on first also remember you have to reapply quite often especially if you're swimming and or toweling i love that word toweling say with me toweling if your eye muscles are active all day and during your rem cycle when do they rest it's a cycle so they're not constantly going throughout the night there are periods where there's non-rem sleep and your eye muscles are relaxed also it's important to note that different muscles have different utilities and some need more rest than others your cardiac muscle almost never gets a break during the short time that it relaxes but your heart beats maybe a hundred thousand times a day on average it's a lot of work and it doesn't stop when you sleep or when you sneeze myth busted hey doc are you considering getting another tattoo me i am i think i have what i want but i don't know where i want it so i'm open to suggestions it is text so feel free to text on my body right now and send me a tweet of what you've texted on me can i use chopsticks absolutely i'm a chopstick rock star i can all day i can eat soup with chopsticks are you on that level why does your funny bone tingle when you touch it or whatever well if yours tingles just when you touch it there's a problem there's some inflammation in your cubital fossa in your cubital tunnel i'm fossa everywhere today in your cubital tunnel here when you hit your funny bone here's what's actually happening and i'm going to blow your mind right now because the funny bone ain't even a bone it's actually the ulnar nerve that runs in the cubital tunnel here that leaves your spine comes down your arm and comes and gives sensation and motor control to your hands and unlike regular pain which is like achy throbby sharp nerve pain like if you damage the nerve directly what you're getting is electrical shooting awkward pain tingly that feels weird are there certain foods or drinks that can induce dreams while you sleep i'm gonna take this question a little differently medications can definitely change the types of dreams that you have i'll give you a personal example if i was to take benadryl before going to sleep i have the craziest deepest dreams like i will go into a murder mystery with bear as my psychic and him and i talk and we solve the mystery together it happened victoria b the lemons make you lose weight are you asking that facetiously if you put two lemons in your pocket do you lose weight if you put two lemons in your stomach do you lose weight no lemons have nothing to do with weight loss in fact lemons if you eat them have calories in them so if you eat enough of them you can gain weight with lemons why is it when you smell something really bad it makes you want to throw up that's probably an evolutionary thing that you've developed to make you stay away from that object because nausea is a very powerful deterrent if it's already in your mouth why you throw up is because your body probably senses something there's a muck there and shouldn't be entering your body and actually encourages you to get rid of it can a person with epilepsy still work in a hospital absolutely it obviously depends on whether or not their epilepsy is controlled because you can't be working with tools if your epilepsy is uncontrolled so if you're taking the medications and you have a documented history of having it controlled you can have many jobs mike you've only broken one bone why are you playing it so safe you're right neil let me go break some is there a difference between cpr and chest compressions cpr just means cardiopulmonary resuscitation chest compressions are part of that we used to give rescue breaths but we realized that there wasn't enough benefit to doing so it actually stopped people from performing the chest compressions which are actually the most important thing to increase someone's survivability until help arrives bronwyn s is it safer to wear over ear or in-ear headphones oh i'm very passionate about this first of all if you are cycling or running outside and there are motor vehicles around make sure you do not use noise-canceling headphones it will save your life second if you use in-ear headphones and you have earwax the earwax gets pushed further and further further back and then it starts clogging yours which can lead to you developing an infection when you're listening with your headphones whether they're on ear or in ear or over the ear headphones make sure that you're listening to less than 60 volume because you will damage your hearing over time if you continue listening above 60 dr mike can you recommend a great source of protein i'm trying to body build zeta depends uh i'm a big fan of getting your protein naturally from foods ideally healthy foods beans nuts uh white meat chicken soy whey protein could be an option for some although it doesn't vibe with everyone's guts some people do have a upset stomach with it does cold weather actually give people colds nope false misinformation but it does increase the susceptibility of colds because if you are very cold and aren't dressed right that can hurt your immune system also in the winter time the air is more dry therefore drying out your mucous membranes and the fun part that i like to talk about most is germ hang time when the air is dry you sneeze into the air the germs hang around a lot longer austin graham hey dr mike why is eating salt so bad i hear about people having to reduce their sodium intake it's not inherently bad we need to stop villainizing nutrients because it creates so many other problems here's the best nutrients and here are the worst nutrients it doesn't exist it depends on who you are and what problems you have if you have congestive heart failure and you already have high blood pressure yeah you should monitor your salt intake because that could be a problem but in general be reasonable listen to the guidance that your doctor has given you as an individual as opposed to reading nonsense articles online that usually doesn't apply to you why is it when you get up too fast you get lightheaded all right fun question about orthostatic hypotension your body has a blood pressure that it needs to maintain in order to keep blood going from the lower part of your body against gravity and feeding your brain right because your brain's at the top gravity is pulling your blood down when you stand up you suddenly need to raise your blood pressure very quickly in order to make sure that the blood keeps reaching the brain so your body has to do is it has to sense that change of pressure really quickly and adjust by squeezing the arteries in your legs in order to shoot that blood back up into your brain now now now now now now if you're a little bit older if you're a little dehydrated you can't maintain a good enough blood pressure or you can't adjust your blood pressure as quickly you will feel a little lightheaded when you get up and that's why you should get up slowly and you should always have support make sure you don't fall how do you know if you have high blood pressure please answer please answer i can tell you have high blood pressure from reading your question here in all caps you measure your your blood pressure using a sphygmomanometer is that how you say it i thought it was this big nominometer such an important point one elevated blood pressure measurement does not equal the diagnosis of hypertension or high blood pressure that is simply an elevated blood pressure reading without the diagnosis of hypertension because it takes multiple little davey dr mike i have to meet you when can we make this happen come on tour details down below seriously tickets are selling out fast and if you wanna meet you gotta you gotta get a ticket i see those drawer trainer things on tick tock till they actually work bro cristiano ronaldo got paid mad money to do that ad and you shouldn't really be using these things
