When I squat, then stand up, I feel light headed. Walking around and then sitting to eat a few minutes later I feel a strange sensation and tap my fingers almost a sense of anxiety, but getting a cold sweat, and if feeling like passing out was going to happen, this being the moment...pulse slow at 60 bpm... Not sure if dehydrated or anxious or low bp or something else .... Suggestion to just see a doctor and get a physical ? Also .... Deep breaths slow through the nose mouth give the same feeling.
