Description:Norepinephrine is a chemical released from the sympathetic nervous system in response to stress. It is classified as a neurotransmitter, a chemical that is released from neurons. Because the release of norepinephrine affects other organs of the body, it is also referred to as a stress hormone.
The sympathetic nervous system triggers a response that is commonly referred to as our 'fight or flight response.' When we are faced with a situation that is potentially dangerous, we need to make a decision to either stay and face whatever we find intimidating or scary, or to turn and run away as fast as we can! Both of these options require our body to work faster and better. This is where norepinephrine comes in.
Applications:Norepinephrine can increase in the amount of oxygen going to our brain - this helps us think clearer and faster.
Norepinephrine can increase in our heart rate - this pumps more blood around our body, helping our muscles work faster and more efficiently.
Norepinephrine can increase in glucose (or sugar) release - this additional sugar gives our muscles something to 'feed on,' which helps them work better and faster.
Norepinephrine can increase in breathing rate - when we breathe faster, we are delivering more oxygen to the body and brain. This helps our entire body work better.
