When I have mini or normal panic attacks my heart rate increases, I get lightheaded with hot flushes and tingling sensation in hands. Why?
In: 48
Your hands go numb / muscles cramp up / face goes numb because of transient low blood calcium. When you breathe fast, you get rid of excess carbon dioxide making your blood less acidic. The albumin in your blood trades 2 protons (hydrogen ions) for 1 calcium divalent cation, making your blood calcium level transiently low in order to maintain blood pH homeostasis.
