Too Much Sitting May Harm Our Brains, Says Studies

Often times when we need to use the power of our brain, we also tend to sit down. This happens at work, at schools, at exams, while calculating monthly expenses, while working on puzzles, etc. A new research has explored how too much sitting can affect the fuel supply to your brain, and thus negatively affect your brain health.

The brain constantly requires glucose for its functioning. This organ which weighs some 2% of body mass demands some 20% of your resting energy requirements, typically in the form of the primary brain fuel- glucose. When this energy supply is distorted, it can impair your brain cells and even damage those. Thus, glucose availability to your brain cells may have brain health implications.

When your brain experiences low or high glucose levels, it has increased risk of developing dementia. Further, shifting between a low and high glucose level is referred to as glucose variability. A higher glucose variability can lead to lower cognitive function. This implies that a strict control of glucose level is needed for brain health.

How does too much sitting affect one’s health?

Prolonged sitting can amplify one’s risk of early death. It has been estimated that in order to counteract the increased risk of death due to sitting for eight hours or more per day, moderate to vigorous intensity workout has to be performed for 60-75 minutes per day.

This is certainly a load of exercise, more than twice the minimum amount of exercise currently recommended for adults. Therefore, reducing sitting can be another health-improvement approach.

Several studies have revealed that reducing and replacing sitting with light intensity waking enhances glucose control (glucose levels which go not go too low or too high) after the intake of food. This is probably because, the working muscles use up glucose in your system, maintaining the optimal range of glucose.
