Norepinephrine has many effects on the brain, one of which is being a neurotransmitter. It makes you feel good, it’s what’s responsible for the “good” endorphins you get from exercise and alcohol, and it is responsible for the “bad” endorphins from the drugs.
This is the reason why we have so much trouble getting and staying asleep. The neurotransmitter norepinephrine is involved in the ‘flight or fight’ response. It works a lot by making you feel good and by making you believe things. Unfortunately, you can have too much of it and you’ll fall asleep, like the girl from Super Mario who wanted to kill Mario and his friends because of her fear.
It’s a bit of an oversimplification to say that norepinephrine is the reason we want to sleep. It also affects your performance during and after exercise. It’s also the reason why we have a lot of trouble learning to drive or sleep on our own. Norepinephrine levels rise from the moment we wake up, so if you’re doing any kind of exercise, take a break, and then do it again.
A little over two years ago, before I had my own blog, I wrote a short post about how some studies had shown that the most common cause of insomnia is overabundance of the neurotransmitter norepinephrine. A few months later, I had a friend who had recently been diagnosed with ADHD (attention deficit hyperactivity disorder), and I began to wonder what might have been going on in his brain.
To find out, I took a bunch of blood samples from both of my friends and then did a bit of postmortem chemistry to see what was happening in their brains. My friend’s sample showed a surprisingly high concentration of norepinephrine, and this was probably related to his ADHD, which is also more common in people who are sleep deprived. Interestingly, he also had an overabundance of the neurotransmitter serotonin, which is also known to have a role in the brain.
I think this is a good example of what happens when the brain goes awry. In most cases, there is a reason why serotonin or norepinephrine gets overabundant. It’s generally because the body is trying to deal with a stressful situation and it’s compensating for too much energy. When that system goes awry, it can cause a great deal of stress to other areas of the brain. My friend’s brain is definitely on the edge of going awry.
The first two letters of each word are a neurotransmitter, which is a chemical that is released by the brain in response to a stimulus. It is responsible for the function of our memories, our emotions, our moods, and our behaviour. When the neurotransmitter is over-abundant, our brain releases more of it. This can have a severe impact on our mood and emotions, which can lead to a lot of physical symptoms like depression, anxiety, and panic attacks.
In fact, there are many neurological conditions that are associated with being “over-norexic.” For example, people who consume too many red meat, which has a tendency to cause an over-abundance of the neurotransmitter norepinephrine, are also more likely to die prematurely.
In this way, we’re like one of those people who are extremely sensitive to the norepinephrine effect from consuming too many red meats. We’d rather eat less red meat than be over-norexic, so we use supplements and drugs to regulate our norepinephrine.
