Along with getting regular exercise, avoiding too much sitting may lower your risk of heart disease, diabetes, and even premature death. And new research suggests it may also help you maintain good brain functioning as you age. A group of people ages 45 to 75 were surveyed about their activity levels and then each person received an MRI scan of the medial temporal lobe (MTL) of the brain, which is involved in new-memory formation. Being sedentary was strongly associated with having a thinner MTL, which can precede cognitive decline and dementia. What may come as a surprise is that exercising, even at high levels, didn’t offset the harmful effects of being sedentary. That means that no matter how much you exercise, you may not be able to make up for too much sitting. But you can start your own personal Sit Less campaign. To that end, invest in a standing desk, or fashion a makeshift one with milk crates or boxes. When you do need to sit for long periods of time, set an alarm to get up and move around for a few minutes at regular intervals — say, every 30 minutes.
“More time spent standing rather than sitting could improve your blood sugar, fats in the blood and cholesterol levels.” According to a study published in the European Heart Journal.
