I've been doing a lot of research into the balance of CO2 in the body (spurred initially by looking into Buteyko breathing). One of the tips is to drink water with baking soda (e.g., a teaspoon) dissolved in it. I'm curious as to whether there are any thoughts on the impact of this relatively easy and cheap tip? Positive? Negative? Neutral-ish?
And could you over-do it? How would you know?
