Have
you ever wondered what makes the muscles around your eyes twitch and flutter from
time to time? The answer to this question is relatively simple. And so is the
remedy.
All
of the six hundred plus muscles that exist throughout your body and head are supplied
by nerves that originate in your brain. If you take it from the top, your brain
induces a signal that travels down through your brain stem and spinal cord and
out through peripheral nerves to reach each of your muscles. The flow of electricity
through this pathway is what allows you to have motor control over your muscles.
Your
brain and spinal cord are much like the water tower in your city. Both are full
of energy and just itching to gush electricity and water out through peripheral
nerves and city water pipes, respectively. In the case of your municipal water
supply, you are able to regulate how much water comes out of the pipes in your
home with your faucets. In the case of your body, your peripheral nerves are your
faucets and must regulate how much electron flow is allowed to come out of your
spinal cord and travel to your muscles.
Getting
back to what causes a twitching eye, the twitching muscle in question is called
your orbicularis oculi muscle. This muscle has two parts: a palpebral
part that allows you to open and close your eyelids, and an orbital part that
allows you to have a wide range of expressive looks with your eyes, a good example
being when your eyes open really wide with surprise.
The
peripheral nerve that acts as a faucet for your orbicularis oculi muscle is called
the temporal branch of your facial nerve. So, for you to open
and close your eyelids or open your eyes as wide as possible, the temporal branch
of your facial nerve must allow just enough electricity to come out from your
brain and brain stem and travel to your orbicularis oculi muscle.
In
the vast majority of cases of a twitching or fluttering eye, the problem is with
the temporal branch of the facial nerve. When this nerve becomes fatigued, it
acts like a worn down water faucet - the flow of electrons is no longer smooth
and even. The result is that your orbicularis oculi muscle will twitch or flutter
as it receives jolts of uncontrolled information from your brain and brain stem.
In case
you missed it, I just gave you the answer to the most common cause of a twitching
eye: fatigue. And fatigue goes hand in hand with stress.
When
the muscles that surround your eyes twitch and flutter, chances are very good
that you are fatigued and stressed. So the remedy for a twitching eye is rest
and relaxation.
Not
muscle relaxants, not pain killers, not chiropractic adjustments.
Rest
and relaxation. Period.
Aside:
in clinical terms, your brain, brain stem, and spinal cord are referred to as
upper motor neurons. Your peripheral nerves - the temporal branch of your facial
nerve in this example - are referred to as lower motor neurons. Twitching eye
muscles are referred to as fasciculations and are a common sign
of lower motor neuron problems, which usually get better on their own with proper
rest and a healthy diet.

Just a note to let you know how much I appreciate your
newsletter. As a fellow health care provider (optometrist) and medical researcher,
I find your distillation of the literature into lay terms to be accurate and very

forward to it every week. Thanks for providing the best online health resource
I have found. - Moorea Maguire
I'm sure as a doctor you hear
your share of complaints. I just thought you'd like to know that there's at least
one person in your "e-audience" that appreciates the time and effort you put into
sending the emails. I really look forward to them. - Linda H., Raleigh, North
Carolina
Many of my adult ESL students are Korean, and enjoy bits
and pieces from your newsletter that I have shared with them. In addition to your
logical approach to health, I enjoy sharing your newsletter because your English
is unfailingly correct as well as easily understood. Thank you for your beautiful

I thank you and your staff
for such a great website. I am former National Level Bodybuilder so I know a thing
or two about health and fitness. Your site is very valuable and I do my best to
pass it on to friends and people I train. It is also a helpful resource in my
career as a human service provider working with clients who need to recover from
substance abuse. I believe a major part of recovery is getting your body and mind
feeling healthy and strong. Thank you again! Great Website! - Michael Christopher,
