This combined with the fact that if a person is dehydrated and they rehydrate with SSBs that leads to increased kidney injury!

In the quest to maximize hydration, do you really need extra electrolytes? : Short Wave U.S. consumers spend more than $10 billion a year on sports drinks, according to Beverage Industry, a trade publication. And we can’t lie that sometimes a Gatorade or electrolyte tablet sounds really ...

I was on @npr.org's #Shortwave Science Podcast in which they discuss whether you really need sports drinks talking about #hydration, oral rehydration salts, and more! Check it out: www.npr.org/transcripts/...

High water turnover, hydration status, and heat stress among Daasanach pastoralists in a hot, semi-arid climate AbstractBackground and objectives. Water is essential for proper physiological function. As temperatures increase, populations may struggle to meet water n

In hotter environments, it is critical to have locally-based water and heat based recommendations to ensure proper health and kidney function

Water turnover (the gold standard measurement) peaks around 7 liters per day for adults at age 40. Further we show that higher water turnover was associated with better hydration status and healthier kidney function.

In this new paper led by Amanda McGrosky, we demonstrate that #water needs are substantially higher among pastoralists living in a hot, semi-arid environment than worldwide water recommendations.

That's so kind of you to say @zoonotic1.bsky.social! Hope all is well

This is great. And it’s even more fun when that person is one of the best students you ever had the privilege to teach. Well done!

What's the deal with electrolyte drinks — do you need them to stay hydrated? Seems like nobody's drinking plain water these days. Electrolyte packets or colorful sports drinks are everywhere. But do you need them?

It was really fun getting texts and calls from old friends that they heard me on NPR this morning! Really enjoyed talking to NPR's @pien-huang.bsky.social about #water needs and #dehydration - have a listen! @psuanthro.bsky.social @pennstateuniv.bsky.social @pop.psu.edu

one of my favorite things about knowing so many amazing researchers is hearing them on @npr.org! I woke up to texts this morning from people saying they heard @asherrosinger.bsky.social talking about hydration!! www.npr.org/2025/08/04/n...

Excited to share our paper in the Aug issue of Hypertension! Shockingly no health standards exist for sodium & chloride in drinking water, only palatability standards. We show water NaCl is assoc w higher BP, hypertension & albuminuria w effects below palatability

All-star alert! Huge congratulations to @kellyrosinger.bsky.social and team on their Gates Foundation grant!

Drinking water is getting saltier. How does that affect humans? In the United States and across the world, research shows that groundwater is becoming saltier. Higher levels of salts in water may be harmful to people...

“Salt intake is a key risk factor for hypertension and chronic kidney disease. Yet, drinking water is overlooked as a source of salt,” Rosinger explained. “This study will help us understand how much it matters when saltwater enters our drinking water”

Really important thread from one of the best program officers NSF had - if you are wondering about NSF read below

Upon learning that yesterday would be my last day as a program officer at the National Science Foundation, I shared this parting message with my colleagues. The next few months will be frenetic and stressful for them. Here are some things that you can do to help them with the mission ahead. (1)

I saw that one report - but I haven't seen any other news stories about it

The NIH Climate Change and Health Initiative website (climateandhealth.nih.gov) is still down - any insights? @davidcorn.bsky.social

YIKES!!! The climate change and health initiative website at NIH is gone! All these websites from climateandhealth.nih.gov are down

Thanks to the National Science Foundation - Research Experiences for Undergraduates in particular for funding the field school. Those programs are incredibly valuable for providing research and training experiences as well as mentorship that results in real products that help the careers of students

A bright spot - one of my mentored undergrads just had a first author paper published!! We evaluated how different #heatstress measures relate to #hydration status & #thermal #heat perception in a semi-arid environment.
tl/dr: Ambient temp & WBGT > heat index

The Epidemic Intelligence Service was incredibly formative for me & 2 of the best years of my career. This is such a travesty and utterly thoughtless. EIS is the best of the best. They are losing those who could go into medicine, industry, etc & instead choose to make less to serve public health

The abrupt terminations of more than 1,000 employees, including new Epidemic Intelligence Officers, across CDC are deeply disturbing. For more than 70 years, EIS officers have served on America’s front line as its disease detectives, ready at a moment’s notice to respond to emerging outbreaks.

Apparently all institute directors are being asked to retire - this would set back NIH to the stone age
