Sympathetic acute stress disorder is caused by the release of excessive adrenaline and norepinephrine into the nervous system. These hormones may speed up a person's pulse and respiratory rate, dilate pupils, or temporarily mask pain. This type of ASR developed as an evolutionary advantage to help humans survive dangerous situations.
There are several known causes of adrenergic storms; in the United States, cocaine overdose is the leading cause. [16] Any stimulant drug has the capacity to cause this syndrome if taken in sufficient doses, but even non-psychotropic drugs can very rarely provoke a reaction.
Night time anxiety can cause you to wake up at an unusually early hour (say, 3 a.m.), feel like you haven’t had enough sleep, and then feel pressure to go back to sleep, explains Virginia Runko ...
The fight-or-flight or the fight-flight-freeze-or-fawn [1] (also called hyperarousal or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. [2] It was first described by Walter Bradford Cannon in 1915.
Adrenaline junkies are often introduced to risky and thrilling sports and activities by a friend, family member or work colleague, then finding that they enjoy the feelings associated with doing them.
An increase of serotonin in certain pathways of the brain seems to be correlated with reduced anxiety. More evidence that suggests serotonin plays a role in anxiety is that people who take selective serotonin reuptake inhibitors (SSRIs) tend to feel a reduction of anxiety when their brain has more serotonin available to use.

"The brain is a massive consumer of oxygen and energy, and creatine seems to help with the process of energy and nutrient utilization," explains W. Christopher Winter, MD, a neurologist and sleep ...
[11] [12] The anterior cingulate cortex in the brain is largely thought to be the main area associated with emotional response and awareness, which can contribute to the way an individual reacts to startle-inducing stimuli. [11] Along with the anterior cingulate cortex, the amygdala and the hippocampus are known to have implications in this reflex.
