Oft wird uns gesagt, wir sollten mehr Wasser trinken, aber die tatsächlichen Vorteile eines erhöhten Wasserkonsums sind nicht eindeutig belegt. Eine neue Überprüfung ergab, dass eine kleine Anzahl von Studien darauf hindeutet, dass eine erhöhte Wasseraufnahme Vorteile bei der Gewichtsabnahme und bei Nierensteinen hat.

I’ve linked to the news release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:
We often get told we should drink more water, but US experts say the actual benefits of increasing water consumption are not well established, so they set out to review the evidence that drinking more water is good for you. They found that while there is a limited number of clinical trials, a small number of studies did suggest increasing your water intake has benefits for weight loss and kidney stones. There were also individual studies which they say raise the possibility of benefits for migraine prevention, UTIs, diabetes control, and low blood pressure. They say that given how cheap and safe water is, we should have more well-designed studies to assess the benefits of drinking more water for these conditions.
Adding to post,
Four studies (22%)18-20,28 evaluated the effect of water on weight change in participants with overweight and obesity. In 3 parallel group RCTs,18-20 adults with overweight and obesity randomized to consume 1500 mL of water per day before meals for a period of 12 weeks to 12 months had greater weight loss compared with those in the control groups (approximately 100%, 87%, and 44% more weight vs control groups).
In a fourth study including 38 participants who reported drinking less than 1000 mL/d, drinking 2000 mL/d was not associated with weight loss over a 6-month period
im not an expert, but if my chemistry holds, kidney stones can only form in an oversaturated solution of whatever they are made of. so thinning that solution by making your kidney process more water sounds like a no brainer
if it looks like orange juice…
drink water even if you don’t feel thirsty.

Anyone paying attention would notice that the whole “hydration” craze started when pepsi and coke started bottling water and selling it as a “health product”.
There is no new science, just a new product line. Much like the whole “lo fat” products to lose weight that never worked.
Attended a talk a couple of years ago on a study that showed links to undesired accumulations of stuff like calcium when not hydrated.
Geez, I hear from doctors and regular people that we should drink water to prevent kidney stones for at least 30 years, I thought it was well studied and confirmed!
If you dig back, you find the recommendations for 2l/day arguably go back to the WWII experiments on how much fluid intake you need a day. And these were explicitly not talking about drinking water, but all fluid, including that incorporated in food.
The amount of additional water people who are drinking other fluids (tea, coffee, milk) need will often be zero, to meet reasonable needs.
As a microbiologist, you don’t want stasis anywhere in your body. Flowing fluids and solids help prevent bugs from getting comfortable and colonizing/invading tissues. Staying hydrated is one way to make sure you wash bacteria down and out of your body – mouth to stomach acid, bile duct to intestine, intestines and bladder to toilet…
Several studies and systematic reviews have established these benefits:
1. Kidney Function: Increased water intake is associated with a lower risk of chronic kidney disease (CKD) and albuminuria. A cross-sectional study found that higher water intake correlated with a reduced prevalence of CKD and albuminuria. Additionally, a systematic review and meta-analysis demonstrated that increased water intake significantly reduces the risk of kidney stone formation.[1-2]
2. Cardiovascular Health: A systematic review and dose-response meta-analysis of prospective cohort studies found that higher total water intake is associated with a lower risk of cardiovascular disease (CVD) mortality. Specifically, each additional cup of total water intake per day was associated with a 3% lower risk of death from CVD.[3]
3. Blood Pressure: Increased water intake has been shown to lower systolic blood pressure. An open-label, randomized controlled trial in Japanese adults demonstrated that water supplementation significantly decreased systolic blood pressure.[4]
4. Hydration and Metabolic Health: Higher water intake has been linked to better hydration status, which is associated with improved lipid metabolism and lower cardiometabolic risk biomarkers in older adults.[5]

this is false, the actual benefits of water consumption are very well established, because it’s a basic bodily need, and we have thousands of peer reviewed studies on the ill effects of long term dehydration.
This is some backwards as pseudoscience basically arguing something along the lines of “we haven’t proven the benefits of breathing just that you die if you don’t”
It’s like you knew I just bought water bottles that have daily hours on it to help me drink a full bottle everyday.
Do we really need to study the effects of drinking other liquids like soda or caffeine to see the importance of staying hydrated? I don’t think so.
Beer has soft water in it, so drink more beer!
I would argue that the consequences of dehydration are significantly well established.. and uhhh, well, the way to address dehydration is to uhh hydrate.
Pretty certain it’s always been known increased water intake reduces kidney stones…..
I’m sticking with drinking when it sounds appealing. I’ve never drank because I thought I should. 51m, 35 years of weight lifting and interval training. Some days I want to drink more, some I don’t. Seems to be working according to my doctor. Usually not one to argue with science but I’ve never understood the hydration craze.
I see patients weekly that drink literally zero water by their report. so any increase would be beneficial. Especially if their daily “hydration” is 6 cups of coffee and 3 sodas. As with most things, the potential benefit of increased water consumption should be compared to the individual’s baseline. Secondary benefit also exists as replacing 3 sodas with 3 glasses of water greatly reduces sugar intake as well.
As someone who just accidentally gave myself hyponatremia by drinking too much water I’m now a little suspect of good old water and am drinking more electrolytes etc.
I mean… There’s probably diminishing returns after a point, but it’s clear that most people don’t drink enough water.
