There exists more hormone like Adrenaline.
As far as I know, two of them are Norepinephrine (released from the adrenal glands and also from the brain ) and Cortisol ( produced by the adrenal glands ).
Norepinephrine isn’t as important as Adrenaline But In survival mode, the optimal amounts of cortisol can be life saving. It helps to maintain fluid balance and blood pressure.
BTW thanks for sharing your opinion 🙂
