Dear MEL Topic Readers,
Why you are probably sitting down for too long
How long do you usually keep sitting on an ordinary work or school day,
four, eight, or twelve hours? If you keep sitting too long, you’ll spend less
energy and circulate blood less fluently, which could be associated with risk
factors for cardiovascular disease, type 2 diabetes, and premature mortality. Also,
reduced muscular activity lowers metabolic demand and burns less calories. If
you don’t move your legs for long like being on a long flight, blood flow to
the leg muscles decreases and causes blood pooling in the calves, called deep vein
thrombosis (DVT), which could clog the blood circulation. It was found in 1953
that London bus drivers, who were sitting most of the time on the bus, developed
coronary heart disease twice as many as bus conductors, who were always standing
or walking around the bus. So, whatever you do, if you keep sitting so long,
stand up and walk around, or move your legs from time to time to help blood
circulation and metabolic activity. After all, human bodies have evolved to be
able to walk upright most of the time.
