Bahahaha. Depends on the individual and how well they absorb water naturally. I have to get some electrolytes, but it’s just a tiny bit of table salt each day (could even be eating like 5 saltines and a whole bottle of water). Humidifier is less important (in my experience/opinion) unless you’re waking up with dry skin, nose, and throat. I do potassium and magnesium a little bit, but potassium is best absorbed for me by literally eating a banana, whereas a lot of research indicates the magnesium absorption is most efficient transdermally so I do an epson salt bath biweekly.
