If you are Rh negative and your lifestyle is a healthy one, you may not have it.
Acidic sweat can indicate an acid imbalance in your body. When your body has too much acid it can pass the excess acid through your sweat glands causing acidic sweat. Eating high alkaline foods like fruits and vegetables can help.
Acidic skin has been driving me crazy for years. Right now I am typing on a keyboard where the letters cannot be seen. If I could I would include a picture of the keyboard or a picture of the many other keyboards I have destroyed with my acid skin. And yes it also has an effect on clothing making certain areas of clothing thinner where I sweat. Something that is really irritating is my tears are acidic and burn my eyes like crazy. I go through eye wash and eye drops all the time. Recently, I had some information in an email my wife had to fill out from my lap top. I had opened everything and it was all set up for her to start work. Took the lap top into the bedroom, set it on the bed and left. A short time later an irritated wife was standing in front of me with the lap top telling me, “thanks a bunch”. I had forgotten she couldn’t see any letters on my keyboard. I apologized even while I was laughing. I had typing classes in high school and I’m used to the keyboard. I do get some typos but they show up in red on the screen. BTW, I’m RH A– (negative). I have so many RH characteristics I can’t count how many. Big ones are things like my L6, Hazel eyes, intuition (my crystal ball), etc.
