IAmA Board-Certified Kidney Doctor. AMA about water balance, electrolytes, and goofy water myths.

503 Upvotes

We’re back for round 3(?)! I’m a board-certified nephrologist (kidney doctor) with some time kill, so ask away. I will also field questions about the Grateful Dead, bicycles, or my favorite conspiracy theories.

Previously I have submitted proof to the mods, so hopefully they can just review my last post(s).

I will not be able to provide personalized medical advice, both in this thread or in a DM.

Edit: That’s all for tonight folks, thanks for tuning in!

Mod-Post Vetted Water Charity List

19 Upvotes

This thread will serve as a repository of vetted charities that have contacted the mod team asking to post here. With each charity you'll see a link to Charity Navigator and/or Charity Watch. We advise only donating if an organization passes these reviews. Feel free to also check any groups on ProPublica's Nonprofit Explorer, but note that not all charities are nonprofits.

We don't want orgs to spam the subreddit asking for your time/money, so for now (and until the number of asks grows too large) we'll pin comments by organizers in this thread and cycle them out as needed. There's a limit of 2 concurrent pins, so we'll play this by ear for a bit.

I'll update the list as others reach out.

If you're here as an organizer, please shoot us a modmail or reach out to me directly.

I just saw this posted over on r/baltimore.

“Responsible hydration” sounds a bit judgy to me. OTOH, I can imagine it’s not easy to manage all those little bladders.

I’ve organised a hydration party at my home. No food, only liquids (and a little sugar for some people). This and obviously some of the green stuff to get people thirsty. ;)

Classic water Hydration with a smart water bottle - Uni project study(4 Q&As in comments, takes 2 minutes)

0 Upvotes

Hello Hydrohomies. This is a uni project regarding hydration.

We are trying to find ways to keep people hydrated as many among us often forget to drink enough water. This is the first iteration - a smart water bottle. It reminds you to drink at regular intervals and you can set a goal for the day which the bottle keeps track of based on weight. Also completely customizable ESP32(or similar), own code, small touch screen, RGB LEDs, share with your friends(connect to Discord etc), machine washable, wireless(batteries) - all the goodies.

Now to the questions:

  1. How often do you forget to hydrate? Scale of 1 to 4 with 4 being forgetting constantly.

  2. Would a smart water bottle encourage you to drink more water? Scale of 1 to 4 with 4 being greatly encourages.

  3. What would be the preferred method of reminder: lights, sound, vibration? Or combination of.

  4. Open feedback about anything regarding hydration or the proposed solution.

I greatly appreciate if you take a minute to answer these questions!!! Thank you :)

Water Bottle Wednesday Something comparable to the Brumate Era?

3 Upvotes

I thought I had finally found the holy grail of water bottles when I got the Brumate: insulated, fits a cup holder, with a straw, LEAKPROOF when locked.

I loved it for 6 months or so but now all I get is air through the straw and it drives me nuts. I've tried every way of taking it apart and putting it back together, tightening, etc.

Is there any other bottle that fits these 4 criteria?? Or is there some magical element to fixing the Brumate lid so that it works again?

A water bottle recommendation?

Thumbnail
gallery
11 Upvotes

I currently have a water bottle I've had for like almost 4 years now. It's a double walled stainless steel. Only use it for water no flavorings. It's starting to taste like metal. In my googling I see there's 2 common options of ceramic lined or titanium. My main criteria for a water bottle is it needs a straw and needs a cover over the spout because I have cats and I don't want their hair sticking to the spout lol. I use my bottle all day in my house and also while out so a clean spout is a must. If you have recommendations please let me know.

I think all of you homies should watch this, although exclusive to the USA, it's a wonderfully crafted video about how different scenarios affect the taste of water.

Is this normal in my coconut water???

4 Upvotes

I bought this coconut water, and when I poured it into an ice tray, I started seeing all of these stringy, fibrous-looking particles. Since it says it's pink coconut and they are kind of dark red, I'm thinking it's part of the coconut, but it looks kind of gross. I'm not sure if it's safe to drink. Can someone help me???

Brita Elite Filter

20 Upvotes

My mind has been blown

I've always had a taste in water whether its minerals, chlorine, or dirt, I can taste it in the water. Everyone around me thinks im crazy. I know what im tasting.

I threw out my old brita filter and got the 2 pack elite for 30 bucks.

Im currently drinking air. Its insane. There is NO taste. How is this even possible?! I live in a area with an absurd amount of hard water, no dirt taste now. Im curious how it will be back home where the water is heavily filtrated with chlorine.

Looking for a specific water bottle type

19 Upvotes

I'm looking for something that has:

  • Chug style (I don't care for straws)
  • Fast flow (needs to let air in as you chug)
  • Doesn't leak
  • All or mostly metal
  • Not completely open like a Nalgene (I tend to spill these all over myself when chugging)
  • No Stanley type handle designs

Help me HydroHomies!

There's about a billion water bottle brands out there now

How to get rid of this dirt/mold?

Post image
7 Upvotes

Hello all. I've had my Iron Flask for over 5 years now, and I'll be honest, I haven't cleaned it as often as I wanted, but I used it regularly and thought it was fine. But last week I noticed this little silicone stopper was disgusting, and attempted to clean it with a cheap straw cleaner, soaking it in hot water/vinegar, and trying dawn power wash, but these two little bits won't go away. Should I just trash this and get a new one? I don't wanna have to do that, given i have plenty of stickers on my bottle I don't want going to waste 😭
