Cortisol is the fight or flight hormone, so if something goes bad then your cortisol levels will get higher. You have to have low cortisol levels in order to fall asleep. Serotonin goes hand-in-hand with cortisol, this is because it gets activated when you become more relaxed with the low levels of cortisol. Therefore, make sure your cortisol levels are balanced.
