What Happens If You Go Without Water?

Sorry! This is a re-upload of an episode that went live earlier today. Thank you to all the fans of SciShow who helped us out by pointing out an error in the original upload and thank you for bearing with us and understanding that these kinds of things do happen from time to time!

Ever wondered what happens to your body if you don't get enough water? Our bodies are mostly water by weight, so in today's episode of SciShow Hank explains what happens to your body as it starts to shut down when you go without that tasty H2O.

I wish my science teacher was like you

I'm bookmarking this video under "in case of severe dehydration"

Might just save my life one day. Is there internet connection in the Sahara?

[Virtually_Char]

Hank, did you just tell us we would feel like we're dying mostly because we're dying? Thanks for the info!

Ugh... I have to admit, I do like the notification system, Just not the fact that I get notified whenever my comment, the video I commented on, or the comment I replied to gets up or down votes, I also don't care if someone replied to the same comment as me...

I reached the 5-10% stage every day at band camp last summer xD We need more water breaks! Thanks for making this video, Hank! Your videos are always interesting.

Thank you hank for giving me and excellent reason to procrastinate. Keep making videos

[amandarivet]

I think I'm gonna go get a glass of water now...

[invisiblejaguar]

Thank you for the video Hank. Disturbing but educational. I'm so glad that I live in a part of the world where water falls from the sky a lot of the time. I never want to die from dehydration. We need to focus more efforts to things such as water, it's liquid gold.

who else drank water right after watching this video

[UntamedDragon]

I hope that scishow make a video about how flavour enhancers work someday. It's something I really curious about.

[tencat]

Very simple video and I like how naturally you explain things. Subbed!
However I'd like to know, when do you start getting moderate dehydration? And severe dehydration? I'll be grateful if anyone can answer my question.

[DanteFoulke]

This was actually very informative, as relates to survival skills

[xarin]

I've apparently passed the turgor test with moderate dehydration. I got hooked up to an IV after they figured out through other methods though so it turned out fine.

[apinakapinastorba]

Looked at that pee color chart. And drank some water immediately.

These genre if videos are really interesting and entertaining! You should do what happens if you have limited movement for a long time

[earthjio]

I generally have no problem staying hydrated. When I did live in California (in a desert area), I learned the value of water. I don't like to start my day without drinking water, and I don't like to end it without drinking water either.

how can your brain be mad at you when you are the brain

[themotherbrassica]

Suddenly, I think I completely understand why people with POTS are supposed to drink more water than healthy people--our bodies are already unable to effectively regulate their electrical system.

You + your bro are my idols. I show my 6 year old neice all your guys videos, and see loves them, and loves to learn. Thank you (:
