Physical inactivity contributes to over three million preventable deaths worldwide each year (that’s six per cent of all deaths), according to studies.
It is the fourth leading cause of death due to non-communicable diseases.
Medical studies show that physical inactivity causes 21-25 percent of breast and colon cancers, 27 per cent of diabetes cases, and around 30 per cent of ischaemic heart diseases.
World Health Organization (WHO) suggests 60–75 minutes per day of moderate-intensity activity to combat the dangers of excessive sitting.
Besides causing stiffness of neck and weight issues, too much sitting affects other health functions
Legs and gluteals
Sitting for long periods can lead to weakening and wasting away of the large leg and gluteal muscles. These large muscles are important for walking and stabilizing you. If these muscles are weak you are more likely to injure yourself from falls, and from strains when you do exercise.
Hips and back
Sitting causes your hip flexor muscles to shorten, which can lead to problems with your hip joints. Back problems are also expected due to poor posture.
Poor posture may cause poor spine health such as compression in the discs in your spine leading to premature degeneration which can be very painful.
Emerging studies suggest the dangers of sitting include increasing your chances of developing some types of cancer, including lung, uterine and colon cancers. The reason behind this is not yet known.
One study found that men who watch more than 23 hours of television a week have a 64 percent higher risk of dying from cardiovascular disease than men who only watch 11 hours of television a week.
Some experts say that people who are inactive and sit for long periods have a 147 per cent higher risk of suffering a heart attack or stroke.
Studies have shown that even five days lying in bed can lead to increased insulin resistance in your body (this will cause your blood sugars to increase above what is healthy).
Research suggests that people who spend more time sitting have a 112 per cent higher risk of diabetes.
Deep vein thrombos
A deep vein thrombosis (DVT) is a blood clot that forms in the veins of your leg.
DVT is a serious problem, because if part of a blood clot in the leg vein breaks off and travels, it can cut off the blood flow to other parts of the body, including your lungs, which can cause a pulmonary embolism.
This is a medical emergency that can lead to major complications or even death.
Some ways to reduce sedentary behavior including walking more often, taking the stairs at work, parking further in order to walk longer, taking lunch break away from desk and walking over to colleagues instead of emailing.
