Hi guys, my anxiety symptoms are usually accompanied by a really fast heart beat. Then I worry that my heart is being worn out and it gets worse. 

I learned about the Mammalian Dive Reflex (MDR).

It’s an evolutionary adaptation we all have. If cold water touches your face (specifically by your eyes) your nervous system prepares your body to expend less oxygen and it slows your heart rate. 

I wanted to test it so I triggered myself, filled my bathroom sink with cold water. I measured my heart rate at 109 before. I dunked my face and held for about thirty seconds and remeasured at 82. 

I don’t know if it was a placebo but it’s worth a shot for you guys to try it and maybe also add it to the ways you can deal with anxiety. If you try it please let me know.
