Sitting Is Killing Us

In the mid-20th century, rapid technological advances (think: cars, TVs, computers, etc.) began chipping away at physical activity, and as technology did more of the heavy lifting, people became increasingly sedentary.

A 2008 Vanderbilt University study of 6,300 people published in the American Journal of Epidemiology estimated that the average American spends 55% of waking time (7.7 hours per day) in sedentary behaviors such as sitting.

Physical inactivity is the 4th leading cause of global mortality.

The Science:

Lipoprotein Lipase enzymes in the blood vessels essentially go to sleep after 60 – 90 minutes of inactivity.

These enzymes are responsible for metabolizing fats and sugars in the blood stream. Physical movement is thought to stimulate enzyme activity and improve cholesterol & regulate blood sugar. Lack of movement and low enzyme activity contribute to weight gain, diabetes and a reduction in HDL- the good cholesterol.

It’s a common misconception that exercise can compensate for too much sitting. Even if you engage in the doctor-recommended 150 minutes of moderate to vigorous activity per week, you are still subject to the negative impact of too much sitting.

Low intensity, ‘non-exercise’ activities like standing and walking are much more important than most realize. In fact, low level activities play a crucial metabolic role and account for more of our daily energy expenditure than moderate-to-high intensity activities.

The Good News:

Standing, walking, fidgeting, and contracting/relaxing the muscles every hour or more seems to reactivate the sleeping Lipoprotein Lipase enzymes. This stimulates the metabolism.

What you can do:
  • Practice the sit-stand switch: every 30 minutes; alternate between sitting and standing.
  • Stand up when someone comes to your desk to talk about a project.
  • Incorporate stretching or simple exercises into both seated and standing positions.
  • Conduct standing or walking meetings with team members.
  • Schedule walking times.
  • Standing desks.
