Brain Health: Is Your Desk Job Damaging Yours?

Although your job may require you sitting at a desk all day, your refusal to move can be quite hazardous to your health. This sedentary habit can lead to issues such as poor posture as well as an increase in your risk of heart disease and diabetes.
Furthermore, a recent study recently revealed that sitting might also be bad for your brain.

What does the study say?

Researchers at the University of California in Los Angeles found a correlation between sedentary behavior and memory problems. Specifically the study highlighted the thinning effect that sitting for too long can have on the medial temporal lobe- the region of the brain responsible in the formation of new memories. This is particularly daunting, as brain thinning is often a precursor to neurodegenerative diseases. In the study, 35 participants, aged 45 to 75, answered questions about their physical
activity levels and the average amount of time they’d spent sitting each day during the previous week. They were all tested for the “Alzheimer’s gene” variants (APOE) before having their brains scanned with MRI to measure the thickness of regions in
the medial temporal lobe.

What were the results?

The study found a correlation between participants who spent a lot of time sitting and a thinning medial temporal lobe, regardless of their physical activity levels. The researchers were surprised to discover that there was no correlation between fitness levels and the thickness of the medial temporal lobe. Furthermore, researchers discovered a link between every additional hour of average daily sitting and a 2 percent decrease in the thickness of the medial temporal lobe. However, not all sitting behavior is equal, as what you’re doing whilst seated can have an effect on your brain health. The researchers stated that, “It is possible that there may be two distinct groups: mentally active sitting and mentally inactive sitting. In mentally active sitting, individuals may be attending to cognitive demanding tasks such as crossword puzzles, documentation, writing, or computer games. In mentally inactive sitting, individuals may be engaging in less demanding, passive tasks such as watching television or movies.”

The verdict

It is important to note that the study only highlighted a correlation between prolonged sitting and a thinner medial temporal lobe. It did not emphasis the effect of the loss of thickness. Furthermore, not only are findings of the study preliminary, but the study also failed to take into account the potential difference that getting up and stretching might have had on the study. Thus, the researchers wish to conduct a more long-term study to determine the actual effect prolonged sitting can have on the medial
temporal lobe – taking into account race, gender and weight. Nonetheless, the research does highlight the plausibility that in reducing the amount of time spent sitting, you will likely improve brain health and reduce the risk of neurodegenerative diseases.

How can you avoid the risks of sitting for too long?

As many of us have jobs where we are required to remain seated, it’s imperative that we learn to take short breaks to keep our brains healthy and fresh. Alan Hedge, a professor of ergonomics at Cornell University, explains that you should mix up your daily schedule with both sitting and standing every half hour. Spending too much time either sitting or standing can lead to adverse health effects, which is why shaking things up after 20 minutes of either one is the healthiest way to work.

  • The trick is to sit for 20 minutes, stand for eight, then move around and stretch for 2 minutes.
  • Put a reminder on your phone so that you don’t forget to do so. Even if you work out before or after work, you need to keep moving your body.
  • If you are feeling particularly sluggish, go for a quick walk around the office building.
