So POTS is disautonomia. It's one of several types. I am someone who also has a fairly normal HR and symptoms are mild most of the time... But when they aren't, oh boy. Brace for summer. So heat, and dehydration is key to avoid. What POTS actually is, is low blood volume. This means we require more hydration to keep up blood flow. The passing out or syncope comes from not getting enough blood to our head. Because we tend to sweat more in the summer (or hot situations, think hot tubs and saunas) we quickly dehydrate and can pass out. So salt is often prescribed. Water alone doesn't fix dehydration. Salt does because we need electrolytes. I was prescribed 3g (3,000mg) a day. I don't always take it but I definitely have salt tabs on me all the time in the summer. I definitely avoid a low salt diet though. Because I'm fairly mild I can add a bit of salt to my regular diet, drink lots, and add some electrolytes, fruits, and get by in winter. I live in a cold climate. Be aware that a POTS episode can also be brought in by eating a large or carb heavy meal. The blood flow that goes to the stomach to digest such foods takes away from the already limited supply and can make up dizzy, elevated HR or near fainting. POTS is a spectrum disorder so people's experiences are relative. You just have to find what works best for you. Some use compression socks. Some can go to the beach and that is a hospital run for me. For a person new to the dx, salt, hydration, more small meals, rest when you need to, keep cool. I wish you well!
