Thanks, those are good advices. My water (liquid) intake is okay, I reckon. Base here, is a two litres bottle of (ja, bottled) water (Spa Blue) on a daily basis. One, or two max, cups of coffee (coffee 'steals' water from one's system).. and then there's tea, orange juice, soup, etc..
About the sodium intake.. I don't know. Could be, with my cooking adventures, I sometimes go a tadski over the daily recommended amount. Perhaps at times.. but OTOH I rarely eat processed, prea-made in some 'factory', stuff.. which tends to contain a lot of salt.
Still haven't bought any moisturiser.. most of the shite my skin really hates. It goes itchy a/o spotty red-ish and basically is irritated by it. Wouldn't know where to start looking for a proper one.
And yes, your honour.. long hot showers I am guilty of. Lurve them.. but ja, they can have that drying effect on the skin.
