Need To Combat Sitting Epidemic
Dear Friends & Neighbors,
(Please click on red links & note magenta)
Did you know that Americans are spending more hours sitting than ever before, according to a recent study published in the Journal of the American Medical Association (JAMA). Th findings of this study by Lin Yang, PhD;Chao Cao, MPH; Elizabeth D. Kantor, MPH, PhD; et al, in italics, below:
In this serial cross-sectional study that included 51 896 participants, the estimated prevalence of sitting watching television or videos at least 2 h/d was high in 2015-2016 (ranging from 59% to 65%); the estimated prevalence of computer use outside school or work for at least 1 h/d increased from 2001 to 2016 (from 43% to 56% for children, from 53% to 57% among adolescents, and from 29% to 50% for adults); and estimated total sitting time increased from 2007 to 2016 (from 7.0 to 8.2 h/d among adolescents and from 5.5 to 6.4 h/d among adults).
Prolonged sitting has been associated with increased risk (cancer, heart disease, diabetes, kidney and liver problems) of multiple disease and mortality. Please refer to the video “Are You Sitting Too Much?“, below:
Prolong sitting puts uneven pressure on the spine and leads to wear and tear on the spinal discs, overworking certain ligaments and joints and putting strain on muscles that stretch to accommodate the back’s curved sitting position. This hunched shape also shrinks chest cavity while one sits, leading to lungs having less space to expand into when breathing. The act of sitting squashes, pressurizes, and compresses soft tissues. In the most compressed area, nerves, arteries and veins can be blocked. Prolong sitting also temporarily deactivates lipoprotein lipase (enzyme in the blood capillary walls that breaks down fats in the blood),
Physical activities not only helps to pump blood and oxygen to the brain but also sends mood enhancing hormones. When there is not sufficient physical activities, brain function begins to slow down. After 10-20 years of sitting for 6 hours per day, one may have lost up to 7 quality adjusted years (meaning, years without medical issues or death). If every one sits for no more than 3 hours per day, it is estimated that the average lifespan would rise by 2 years. Researches have shown that inactivity causes about 9% of premature deaths per year.
Let’s take a look at some suggestions to combat this sitting epidemic, below:

- Frequent getting ups or walks. Breaking up prolonged period of sitting can make a big difference.
