Dr. Aviva Romm has another great article and podcast on Anxiety and Adrenals. I personally know this connection and as I have learned how to calm my adrenal glands and lower my cortisol my anxiety gets better! I love Apex Entergetics' product called AdrenaCalm. It is a cream you can put on when you feel wired, anxious and stressed and it helps to calm. Wonderful!
