Avoid sitting too Long


Sitting too long cause a lot of health problems, because blood need to move smoothly through the whole body. When the body is active on motion the heart function well and the blood supply become more efficient. Prolonged sitting has been linked to high blood pressure and elevated cholesterol, and people with the most sedentary time are more than twice as likely to have cardiovascular disease than those with the least.

When we move, soft discs between vertebrae expand and contract like sponges, soaking up fresh blood and nutrients. But when we sit for a long time, discs are squashed unevenly. Collagen hardens around tendons and ligaments. People who sit more are at greater risk for herniated lumbar disks. A muscle called the psoas travels through the abdominal cavity and, when it tightens, pulls the upper lumbar spine forward. 


When you stand, move or even sit up straight, abdominal muscles keep you upright. But when you slump in a chair, they go unused. Tight back muscles and wimpy abs form a posture-wrecking alliance that can exaggerate the spine's natural arch, a condition called hyperlordosis, or swayback. Sitting for long periods of time slows blood circulation, which causes fluid to pool in the legs. Problems range from swollen ankles and varicose veins to dangerous blood clots called deep vein thrombosis.

Moving muscles pump fresh blood and oxygen through the brain and trigger the release of all sorts of brain- and mood-enhancing chemicals. When we are sedentary for a long time, everything slows, including brain function. Walking and running stimulate hip and lower-body bones to grow thicker, denser and stronger. 

Sitting for long periods of time has a number of health concerns, including obesity and metabolic syndrome a cluster of conditions that includes increased blood pressure, high blood sugar, excess body fat around the waist and abnormal cholesterol levels. Too much sitting also seems to increase the risk of death from cardiovascular disease and cancer.


When you sit for an extended period of time, your body starts to slow and shut down on a metabolic level. Since you're not moving around, your circulation slows and you're burning fewer calories and fewer fat burning enzymes are moving through your body. All of this can lead to an overall slowed metabolism that can affect your energy levels and cause you to gain weight.

Sitting for prolonged periods of time can increase your chances of developing diabetes by as much as 7 percent. Why? Sitting all day actually causes your body to slow down considerably and can result in increased blood sugar (since your body doesn't need the sugar for energy it simply stays in your system), insulin resistance and a much less healthy you.


It makes sense that moving less results in loss of muscle mass and muscle weakness. One of the hardest hit muscles is the gluteus maximums, or the buttocks. It is one of the largest muscles in the body and plays a big role in just about any movement you could want to do, so it's essential that it stays strong. Weak gluteus muscles can result in lower back pain and hip bursitis as well.

Sitting at your desk all day may make you depressed through the sheer tedium of it all, but there's a scientific reason for it as well. Reduced movement means less blood flow. Less blood flow means fewer feel-good hormones are moving through your body, helping you keep depression at bay. The effects can be even worse for those who already struggle with or are more prone to depression.


New studies have shown that exercise once a day, even for an hour, isn't enough to make up for sitting all day at work. Those who work out and sit all day are just as likely to develop heart disease as those who don't work out and sit all day, something that should make any health conscious worker reevaluate their daily schedule. Less sitting and more moving overall is the best way to reduce risk of prolonged sitting. You might start by simply standing rather than sitting whenever you have the chance or think about ways to walk while you work.
