It’s true; sitting on one’s
rear end for extended periods is a serious threat to health.
Recent scientific findings
suggest prolonged bouts of immobility such as when sitting is being linked to
serious diseases that has become epidemic in our society.
And this is the problem –
the human body has been designed to be active – very active and it cannot
handle the stress of
our modern sedentary behaviors.
You could say we are an
immobile lot; in fact we are the most physically inactive population that has
ever lived on this planet. We seem to be happiest when we are doing little
other than sitting.
After all we sit at work,
in the car, on the couch, at the bar, at the movies, on the airplane and
watching sport. We sit for hour’s practically comatose watching television, at
the computer surfing the internet or playing video games. A screen of any
description can hold our interest for hours.
We humans are designed for
movement and lots of it. Our evolutionary history has been one characterized by
a hunter-gather lifestyle which involved large amounts of vigorous physical
activity as we have had to seek out our food from the environment.
This is in direct contrast
to modern “easy” and “convenient” lifestyles that most of us now have, where
technological advances have removed the need for physical movement almost
entirely from our lives. A major part of our modern lifestyle involves sitting
and many of us do it for up to 80 percent of our 16 odd waking hours each day.
This is hugely
contributing to the fact that many of us are overweight.
But, the human body
becoming over-fat is a modern problem – statistics for it did not even exist
fifty years ago. But now the incidence of it is pandemic with as many as
two-thirds of the population being overweight to some degree or another.
There are several factors
that have combined to be the cause – motorized transport, labor saving devises,
household appliances along with sedentary jobs where people are sitting all
day. Add to that the increase of convenience foods that are energy-dense with
high levels of sugars and fats but low in nutrients means we are getting fatter
as a greater energy imbalance occurs between calories consumed and calories
expended.
Fifty odd years is not
long for research and understanding of all of these factors to have been done,
so the topic of the rising tide of overweight people in our increasingly
sedentary world is of great interest to scientists and researchers. A new science has evolved called “inactivity
physiology” investigates the effects of inactivity and sedentary time on our
bodies.
Researchers estimate that,
thanks to our non-active computerized lives we burn 1,000 fewer calories a day
(about half a day’s worth for most of us) than we did just 40 years ago. This
is what living a sedentary lifestyle means – it is the type of existence that lacks enough
movement and also does not include intentional exercise to give our body’s the
muscle building and maintaining activity they must have to remain healthy and
well.
It is becoming a global issue
and we now have a new kid on the block called Sedentary Death Syndrome which
has quickly become the third leading cause of death in the US right after heart
disease and cancer.
But the problem is, it is
worse that any one single disease as it is actually linked to another 30 odd
serious conditions and ailments from diabetes to depression to osteoporosis.
The cause of this villain is sitting and is responsible for 2 million deaths
worldwide annually.
Thus sitting motionless
for long periods creates a problem for us as there is an absence of whole body
movement which keeps our body functioning as it is designed to be. This
sedentary time leads to a weakening of muscles, bones, heart and lung function
along with weight gain as the food we eat is not being used for the energy
required for constant physical movement.
Even if the bathroom
scales don’t reflect this fat increase it can be hidden deep in the body and
muscle loss (from inactivity) hides its presence on the scales.
It does not help that most
people mistakenly believe that they get enough activity from the various
activities of daily living, such as routines tasks and chores, self-care and
light recreational activities. But this amount of physical activity from these
non-exercise things barely counts and is totally off-set by the amount of
sitting time most people engage in.
Even if you don’t have a
desk job, it doesn’t mean you are off the hook. It’s not only at work where we
sit. Typically people sit much more than they even realize – on the couch while
watching TV or reading, while eating meals, while getting to and from work
(whether driving or riding a bus or train) – to name just a few examples.
Sitting and Your Risk of Disease
One of the major factors the
researchers have found to be happening is that the act of sitting down shuts
down the circulation of a fat-absorbing enzyme called lipase which has profound
negative effects on fat and cholesterol metabolism.
Fat in the bloodstream is
normally broken down by this enzyme and then taken up by the muscle cells to be
used for energy. But prolonged sitting leaves this fat in the bloodstream to do
damage. After just four hours of sitting and no muscular activity the
body starts to send harmful signals and the processing of glucose and fat in
the body starts to shut down.
As your body falls deeper
into energy-stockpile mode, circulation slows, digestion becomes sluggish and
your calorie-burning metabolic furnace dims to a flicker. Glucose and fat in
the blood hang around and re-circulate with nowhere to go and end up being
stored as excess fat on the belly, hips, thighs and deep inside the body
clogging arteries and doing damage to organs and tissues.
It is little wonder that
people who sit a lot have two to three times the rates of becoming overweight
and susceptible to the killer diseases that are epidemic in the world today. Basically, lack of movement triggers really unhealthy
metabolic changes and if you sit in an office chair or on your couch for more
than six hours a day then here are some disturbing facts:
Your risk of heart disease
has increased by up to 64 percent. You are shaving off seven years of quality
life. You are also more at risk for certain types of cancer. Simply put,
sitting is killing you.
We may wonder why we allowed
ourselves to become so unhealthy.
We know that proper exercise
is not only good for us but has now become a matter of life and death. It is
not some frivolous pastime that we find time for when we have nothing better to
do.
Without enough vigorous
physical activity our body has no way of staying healthy. It needs this
movement to stimulate the necessary hormones that instruct every cell, tissue,
system and process in the human body to repair, rebuild, renew and replace itself.
To save your own life and
remain vigorous and healthy you might need to do something that might feel
uncomfortable and unnatural, especially at first. You need to move and exert
yourself but after you overcome your inertia and do some vigorous activity; you
will become aware of the immediate benefits to your mental, physical and
emotional well-being. You will also recognize that this was exactly what your
body needed.
Don’t let your body
deteriorate from lack of use. It’s the only one you get issued with so it makes
good sense to do some basic maintenance so it won’t let you down somewhere down
the track.
This is such an easy
problem to fix. A proper strength training exercise program performed just 2-3
times each week that keeps the muscles strong and healthy is at the top of the
list. Then smaller snatches of activity at regular intervals throughout
the day. Simple things like squatting down and up a few times (even beside a
desk) will engage the big muscles of the legs and get the circulation of fat
burning enzymes pumping again to keep the body healthy.
Instead of looking for
opportunities to be seated, look for opportunities to move as much as possible
each day.
Too much chair time will
kill you – there are no “ifs” or “buts” about it and you will need to move and
exert yourself on a regular and consistent basis to offset the damage that is
being done to your body by too much sitting.
If you do work seated
consider getting a standing or height-adjustable desk. It’s become a trend, so
jump on the bandwagon. It’s an easy way to reverse the amount of time sitting
each day. Instead of standing as a break from sitting, you can sit when you
need a break from standing.
Eventually your body will
adjust and it will feel more natural to stand throughout the day. I have been
using one for the last 2 years and wouldn’t go back to sitting for long
stretches.
The good news is that
after you have gotten used to your new found activeness, you will also become
more aware of other positive benefits that you will experience. You will begin
to recognize that staying strong is exactly what your body needs not only
physically but mentally and emotionally as well to be truly healthy and vital.
We each have to take
action to avoid becoming one of the millions of people predicted to die of
preventable disease in the next decade caused by inactivity. Sitting and living
an inactive lifestyle is a dangerous enemy as it is silent and hidden.
But becoming more active will defeat this villain and not only will you look
better but you will feel better too.
Combine your strength
training program with a satisfying whole-foods nutrition plan that supports
your exercise program and you have the perfect formula for sustaining a
healthy slim body for life.
It’s time to throw away all
the false statements you’ve accepted about dieting and exercise and learn what
it really takes to reshape your body, take weight off and keep it off for good…
