When I lay down at night, my heart pounds; I don't consume caffeine or exercise before bed. Any ideas?

Maybe you need to use 2 pillows so your head is higher and you can breath easier.

It is because of venous blood return from your lower body. When you lay down, gravity makes all the blood in your lower half go rushing back to the heart and the heart steps up the speed and efficiency to process the temporary excess of blood.
