One of the most effective things you can do to protect yourself from catching a germ and becoming a statistic, whether it’s a global pandemic like COVID-19 or just every single other day of your life, is something that people have been trying to get you to do since you were like 2. Wash your hands. With good ol’ soap. And do it the right way. That’s it. Here’s the science of handwashing!

Hey smart people. Wash your hands. That's all. Here's the real science of why soap is such a darn good germ killer, and the scientifically-approved method for washing your hands. I'm on Twitter and Instagram: @DrJoeHanson @okaytobesmart
And go check out this video about soap chemistry from our friends at Reactions! th-cam.com/video/K2pMVimI2bw/w-d-xo.html
I'll do that.
I don't want em germs.
HI, love your videos you teach me alot
One small point - you turned off the water with your clean thumb. Just proves the price of health is eternal vigilance.
Problem at the moment, I'm washing my hands so much that it is really drying my hands out. My hands are cracking and bleeding and pretty sore
You should've washed your wrists also and do not close the dirty water tap with your clean hand. Use paper or elbow something like that.

Hey, there is a bit about DIY DNA extraction, even if its just at an amateur level and more for looking at then testing. But like, its still DNA extraction for like 0.50$ of materials? thats dope.

It is weirdly comforting to see you again after all this time.
That cell bursting experiment at the end is genuinely one of the most interesting experiments I have ever seen. Never thought I would see cell guts without a microscope.
Awe, you never got to do that with onion DNA in middle school or high school? That makes me sad for schools and makes me wonder what people are learning.
@@___LC___ mine was done on Strawberries.
The Action Lab did this with animal DNA.
@@___LC___ Well, some of us went to school in a time when knowledge of DNA was not so commonplace. Please don't judge those of us who kept learning as adults.
@@___LC___ You know, I think I do remember a lab we did back in 8th grade for Living Environment/Biology that involved unions and using substances such as iodine the see the cell walls and the interior of the cells, but I am pretty sure we still had to use microscopes. But if this is not the same experiment as the one you are talking about, can you explain it, I am curious? Also, regardless of the onion experiment I did, this experiment which I have not seen before still interests me the most as far as biology goes, I have never liked biology that much but this was really cool.
And, at least the science that I have learned in the past recent years of school, middle school and high school sciences still have offered a fair amount of knowledge and experiments, although yes I wish we did more than just memorize principles and equations at certain times, especially recently with my chemistry and physics classes. Both had a rather equal sharing of equations and lab experiments applying the knowledge, but I still yearn for more simply because I really love the sciences.
I wish he was my college professor. Explains everything simply.

Surgical soap is so effective because it has a purple dye in it that shows when you haven't scrubbed all the soap off so you don't carry the soap into surgery.
Yes and no. Betadine soap is most frequently used and is reddish-brown and easily seen. Chlorhexidine may be dyed or not. The dyed is use to disclose areas of the patient's skin that haven't been painted (scrubbe). Preps are contact germicides. The longer they make contact, the better they work. Except in unusual situations, they should not be removed from the pt's skin until after closure. Then it's done largely for aesthetics.
Guessing here, but does the dye also initially help see where you haven't scrubbed with soap yet?
@@noisycarlos Yes.
“The current literature suggests that the use of alcohol hand rubs provide similar, if not better, reductions in bacteria colony forming units, both immediately after hand antisepsis and in the immediate postoperative period.”

I don't know why but I had a good chuckle at that.
Loved the science info, but one critique: after done washing your hands, you turned off the faucet (the last time), with said hand! Always use an elbow, wrist, or paper towel to avoid recontaminating after done rinsing.
I have always washed my hands to a high standard, and being a chef I'm always washing my hands like 8 times a hour easy....
Hey, be careful with laundry detergent! You can use it to wash your hands, but you need to dilute it first. The concentrated form can damage your hands.
And please, please, PLEASE, don't eat them...
For Pete's sake who is doing that on purpose?

But, I believe that he used a liposome in the representation, not a micelle. I could be wrong, afterall I'm only a humble English teacher.
Many should have been watching this a month ago!
how fucked up is it that fully functioning adults need to be taught how to wash their only set of hands
I'm sorry but if you don't wash your hands after using the restroom you deserve to go back to kindergarten.
Ok
@Ellotherem8 I can't tell if you're joking.
@@ericolens3 ok thank you
Rest room???? It's a toilet.
I'm gonna be difficult, and suggest that's the wrong way around - for boys. Think about it. Get up, shower, wash all our bits, tuck them away in nice clean underwear, and go out into the world. Then our hands touch dirty services, shake hands with dirty people, handle nasty things everywhere. Then we go to the toilet, reach into our pants with our filthy hands, find the cleanest and most protected part of our body and ........
I've never been so amazed by soap...
Thank you for using your platform to help people understand how to do this seemingly simple task properly. It's surprising how difficult it is to do a good job cleaning your hands.
A good way to think of it is to imagine you have written someones number on your hand; we've all done it, and how hard/thoroughly you have to scrub it off with soap, now imagine your hands are covered in writing!
Whoever did that thumbnail needs a raise!
From that singing while washing hands, I doubt that germs/virus will still live lmao 😂
This makes me want to wash my hands over and over for all of the times I didn’t
Me a germaphobic: u fking n00b
Yet washing your hands too often can lead to dermatitis/dry skin which traps germs a lot better so makes it far harder to scrub them off.
So if you do wash your hands a lot then invest in a decent moisturizer
I've fallen in love with your channel since the moment I discovered it on you tube, you guys are doing extremely good job educating people and now you are needed more than ever! Thank you!
Just want to say thank you for still being able to produce content from home and the effort you've gone through to explain the chemistry really well! Thank you!! ☺️
Please tell me I’m not the only one who saw the sign behind hims that says “Hold on, I’ve gotta overthink about it.”
This video is amazing! The experiment was an eye-opener. This is the second video that I'm watching, and I haven't looked once at the time left of the video -- that's how intriguing your channel is. KEEP IT UP!
Soap busting open cells.... Is this why getting soap in my eyes hurts? Because my eyes don't have a layer of dead cells?
One quick correction: you said that soap may not be enough when it comes to bacteria such as Clostridium. Soap is actually better when it comes to Clostridium difficile because it will not only kill the active bacteria, but also help you get rid of the spores unlike sanitizer.
The Alton Brown of science...
The greatest compliment I could be paid
@@besmart AB actually got me into chemistry
Thank you. LOVE that you don't leave the water running while you scrub. My hero for life.
I love the *HOLD ON, I'VE GOTTA OVERTHINK ABOUT IT* sign in the background at the beginning.
I don’t know if it’s just me, Joe looks like younger version of Dr. Emmett Brown from Back to the future.

i am so glad i found this channel!! i found it because of the previous video about coronavirus. and once i watched that, i started watching other videos on the channel. your videos are so interesting, and i love the way you explain things! 😊 and this video is really good too (i admit, i don't wash my hands carefully enough...) i just subscribed!

FireyCyndaquil try applying some moisturizing lotion. Whenever I wash my hands or use hand sanitizer, I make sure to put lotion on. This will stop your hands from becoming dry
that's where moisturizer or lip balm come in
You're doing it too much. Use a skin cream of some sort, too.
Definitely find a fragrance-free skin cream (fragrance can make the irritation much worse). Vanicream and CeraVe are great.
Firt desinfect, then use mosturizer

So Joe,that was YOU in that washroom watching me wash my hands? Hmm... guess I don't mind as long as there's not TOO much watching what my hands were doing BEFORE they got washed.
Thanks for calling me a smart person. And thanks for showing why soap/hand washing is so effective! I was literally wondering that very thing.

Great video - I feel vindicated.
I've had a few people try to argue that it's gloves that we should be wearing - I'll stick with washing my hands.
Oh, and stay safe everyone ✌️
I wear gloves when I go to the grocery store. BUT NOT BECAUSE IT TAKES THE PLACE OF WASHING MY HANDS WITH HOT SOAP AND WATER. Nope, it's because I have a terrible habit of touching my face. The gloves remind me not to. After the gloves come off, it's hand sanitizer. When I get home, it's hot soap and water up to my elbows.
@@KoralMae And because you'll be handling items there.
@@KoralMae I'm not criticising anyone for wearing gloves - surgical, nitrile or regular leather or woolen gloves - you do you.
However, some people are being given a false sense of security by gloves - wearing them for hours on end does not alleviate cross contamination or germ transfer.
If we all had a huge supply, doubled up and removed and binned the outermost set after every action then they'd be perfect.
I've been wearing gloves, but I've also been fastidious about hand washing - possibly too fastidious as my hands have dried out.
The issue is people sticking on a pair of gloves and thinking "that'll do" for the day.
Anyway, sounds like you've got the correct approach.
Take care & stay safe✌️
@@KoralMae I don't wear gloves, BUT, when I get home (avoiding touching my face) I have a solution of 1/3rd cup of bleach to 3.8 litres of water (1 US gallon) in a spray bottle ready at home. I wash my hands then take the bottle and cloth to my car and spray the steering wheel, indicators, handbrake, door handles and door grip then my house door handles and then the shopping bag handles and bottom of the bags. Also wipe plastic milk bottle handles and other plastic bottles. Then wash my hands again. Then I relax knowing I have made a reasonable effort to protect myself. If i do catch the 'lurgi' it was not without want of trying.
The best sciencie youtube chanel. Very interesting and well explicated.
I really enjoyed that. One of the better explanations so far. Thanks Joe.
Your hair looks great Joe, especially when light hits it.

I clicked in on this and thought, "dang, 14 minutes on washing my hands?". I was sure I would leave after a minute or so, but it kept getting more interesting, and by the time it ended, you had really captivated my interest. Good job!
Thanks Joe! Very informative
I wish he had explained the myth about warm water because I’ve had to argue about that with several people in the past.
Actually warm water speeds up physical and chemical processes significantly when treating your germs and viruses with soap.
@@norbertfleck812 And it feels much better, too.
If the water is hot enough it could kill germs. (And your hands could get burnt, but that doesn’t matter, right?)
Brian McNally: I don’t know what you mean by”the myth behind warm water” but I have heard that warm water gets rid of germs better. Is that untrue?
@@enderlord5347 I am not talking about hot water (above 40°C). But it makes a difference if you take 10°C water or 35°C water. In warm water with soap you achieve the same germ an virus killing effects much faster, because the soap (tensides) can interact more efficiently with the cellular membranes.
When I was in India, I used all sorts of random bits of soap to wash my hands in public. My cousin told me, "that soap is dirty". I was like, "whatever, at least my hands are cleaner than they were before". My cousin is a dumbass.
I won't blame him. The marketing has brainwashed consumers all over the world into thinking that.
You guys never disappoint, but this one was especially brilliant. Thank you!
You have a lot of great content, but that DNA at the end was some of the most interesting stuff I've ever seen on youtube. Seriously interesting experiment and you toss it out at the end like it was nothing. Keep up the great work!
Dumb question: how would a residue of soap on a hard surface affect the germs - if at all?
same way it affects germs on your skin but it's better to still rinse the surface
People forget that touching the faucet handle is a way to get germs back on your hands.
what if I'm so paranoid that I go out of my way to wash the faucet as I wash my hands?
@@blueninja012 That's not paranoid, that's logical. -If it's your sink at home.
