We shouldn’t 100% eliminate sodium from our diets. I have started trying to put it back in after using other seasonings instead of salt. We overdo some things, but articles can be misleading. Sometimes the extreme conclusions are not the conclusions of the scientists conducting studies. One thing we learned in the medical schooling I did was to pay attention to the end of the web address to know what to take the most seriously. .com is going to be more misleading than .org or an actual scientific study done by a university, which are less likely to be for profit or an advertisement. We were not allowed to use a .com for our research papers and I admired that rule. In high school we were asked to use more physical books than websites, which was a decent rule of thumb as well. Sure, all the clutter tv shows want us to sell our encyclopedias in lieu of information on computers and smartphones, but we do put too much stock into what we read online. I would say I am still reading articles from Brightside. Just be careful when it comes to medical advice! =)
I found related authentic study in this article. https://brightinside.net/how-warm-water-can-be-a-real-medicine/
