The fight or flight response prepares your body to fight the lion or take to flight. As long as the lion is chasing you, it is not in your best interest to feel sleepy. Nor is it in your best interest to even think about sleep. Instead, your body is set for action. As a result, you will not relax and allow sleep to ensue until the fight or flight response has passed.
Coming Out of the Fight or Flight Response
It can also be helpful to lay on your bed for a while. This will allow the blood to leave your arms and legs and return to your internal organs. Once this happens, the fight or flight response can pass. Try some calm and soothing music or a silly movie while you lay down for a while. A relaxing conversation with a loved one can help as well.
Soothing Your Adrenal Glands
Soothing your adrenal glands may be necessary to come out of the fight or flight response and stop the insomnia. Ginseng, Licorice, B vitamins and Vitamin C are all needed to sooth the adrenal glands. Note that the licorice needs to be used with caution if you have high blood pressure. Why? Because licorice may make your blood pressure higher.
