Many of us have jobs where we sit at our desks for eight hours a day. But a new study finds that in doing so we may be compromising the long-term health of our brains by slowing the blood flow. The brain requires oxygen and nutrients found in the blood and is of such utmost importance that the its delivery is tightly regulated by the brain. The brain monitors various physiological factors to adjust to blood flow rate. The study that was conducted, using 15 healthy adults, found that the blood flow to the brain was optimized when the person incorporated two minutes of walking into their normal 30-minute work period. While the study was modest in scope, it did confirm that sitting for long, uninterrupted stretches of time is detrimental to our overall wellness.
Reflect on these key points:
- 1When circulation to your brain decreases, it can lead to brain fog in the short term and an increased chance of dementia in the long term.
- 2Getting up and walking around for as little as two minutes every half an hour may nullify or even reverse the decrease in circulation associated with too much sitting.
- 3Too much sitting in place can also be bad for circulation to other parts of your body, such as your legs.
“As they had expected, brain blood flow dropped when people sat for four continuous hours.”
