I have heard people suggesting to drink water when you are seated after a tiresome activity. They usually ask to avoid drinking water while standing upright.
Does that have an actual scientific reasoning, or is just baseless advice?
You could slam me for it being easy to google, and I have googled for it. But when we talk about trekking, climbing, swimming, cycling, etc... its a different situation. As a trekker or cyclist I'd be mad at me sitting periodically to get a sip of water.
