The Science of Hydration: How Much Water Do You Really Need?

____

In this video, Jonathan from the Institute of Human Anatomy explores the impact of hydration by discussing how much water and electrolytes you really need, as well as some strategies to help you know if you are sufficiently hydrated. Jonathan also delves into the delicate balance of water distribution, how electrolytes influence this distribution, and addresses the risks of excess and insufficient fluid. Learn about hyperhydration, hypohydration, sensible and insensible water loss, and practical strategies for optimal hydration during your day and during your exercise routines.

***CLARIFICATION***
Hi everyone, I misspoke at about 08:58. I meant to say, "Dehydration is actually the process of moving from a state of Euhydration to a state of hypohydration." I am a little bit surprised that none of us caught this in post-production, but we may have been a little distracted from our channel getting temporarily taken down by the hackers... 😡

Thanks to those who caught and commented on this and thanks to all of those that helped let us know about the hack!

Stay anatomically awesome! (Yes.... that was nerdy...)

[barbridingsTheResinator]

So happy you are back and I am truly sorry you were hacked. I just don't understand what motivates some people. These videos are excellent!

[liltop]

I have asked myself this question so many times and still can’t believe I have to learn this from youtube instead of our governments and schools.😢

I have (spastic) cerebral palsy. I can't tell you how much proper hydration helps me reduce muscle fatigue, reduce the pain and stiffness of arthritis, and many other things. I take hydration very seriously.

[bmar]

This isn't talked about as much as it should be! Thank you for a channel of your size bringing more awareness to hydration. I work a labor job and in an 8 hour shift I see basically 90% of my coworkers never take one sip of water, even during breaks. Not good!

[caribboy]

Thank you so much!
In past years I did regular hikes of 5 to 8 hours, in a hot climate, say from 5.00 to 13.00, living in the Caribbean. (Wide brimmed hat, sunprotection longsleeve clothing etc.). Lots of people, even those with some medical background, have warned me against my 'excessive' drinking, as I usually drink about one liter per hour, do a little bit of frontloading (half a liter or so) and sometimes top-up afterwards with one or two liters because I am really thirsty at arrival. On an 8 hour walk, around 10 liters. 'Nonono, do not do that, you will die from overhydration if you drink more than 5-6 liters per day', they say. I always tell them I practically do not urinate but still lose weight during the hikes even while drinking so much, and that makes them hesitate a bit, but still convinced I should drink less (and faint from dehydration I suppose).
So thank you for this video, it explains exactly why my drinking is justified for the amount of physical activity and the hot climate. (a day at the office, I only use around 2.5 to 3 liters) Will be interesting to see how all the 'experts' will react to this (and info I found on other websites that confirm this) information.

[kathygann]

There was a case where a radio station had a contest about who could drink the most water, and one of the contestants died from too much water.

[jericoba]

Now is a good time as ever to say: Thank you all at Institute of Human Anatomy! Awesome channel.

[Shacon]

Your videos helped me so much with my examen.
I am a dietitian and thus only ever saw basic anatomy classes, but seeing all those things learned in school on a real person helped me out so much!
Thanks! :)

Would be interesting to compare water requirements while in sauna, vs. steamroom, vs. exercise.
Also exploring the connection between muscle cramps and hypohydration.

[Dave_Cymru]

The hackers picked on the wrong channel, it did not take me that long to track them down. I have already alerted YouTube security as to their identity! This is a great post that has cleared up my confusion!

Got my PhD in chemistry from a high quality institution. As a person who suffers from Bipolar and has to take lithium which effects every single electrolyte in my body…..thank you for making this….I know I have the capacity to rehydrate myself but this video certainly helps those who aren’t

[BigDees]

This is such a great channel we cannot thank you guys enough. All you guys here at Institute of human anatomy. THANK YOU!

[CaesarBro]

Dehydration due to living at high elevation is also a factor. If you visit such places, hydrate more often.

[CaesarBro]

When I played college, coconut water was the best halftime hydration choice. My second half energy was almost as good as starting fresh. Better than water and the various gatorade /powerade drinks that make breathing sticky.

[ni-tric]

I've been drinking 3-4 liters a day for several years, and I genuinely believe this is the reason I don't suffer from a lot of issues other people describe to me that sound hydration-related. Makes even more sense after seeing this explanation too

[JamieCraigy]

I took a shot of water everytime he said water

[XRFan]

This is a really informative video, I thought my physiotherapist was crazy when he told me the amount of liquid I should be drinking while working (car detailer) I don't visibly sweat so i never used to drink that much however ive had alot of muscle related injuries and turned out to be a lack of hydration as a big part of it. I usually drink 1L of electrolyte and 2L of water while working now.

[colleendonahue]

Thx for covering this topic. I tend to drink close to a gallon of water most days due to medications and stage 3 kidney disease. Most days my urine is clear to very pale yellow except for my first bathroom trip in the morning. In the morning it's usually slightly darker. When it gets medium to dark yellow and smells like pee, I I usually have a UTI.

[Chebornek]

I for one am elated that I've accidentally discovered this youtube channel. It's like taking those biology and chemistry classes again in HS & university. Plus tons I wasn't taught.
