Your brain may feel as though it has lost vitality after a long day of work or study. But can mental exercise cause our brain to expend more energy than it does during other activities like watching TV?
We must examine the nerve cells, which serve as the brain's power plant, in order to respond to this query
Adenosine triphosphate, often known as ATP, is the primary source of energy for our brain cells and is produced by our body from sugar and oxygen.
Both sugar and oxygen can be used to track brain energy use, but oxygen is more practical.
For an average adult, that equates to about 0.3 kilowatt hours (kWh) each day, which is more than 100 times what the average smartphone uses on a daily basis.
Additionally, it equates to 1,088 kilojoules (kJ), or 260 calories, per day (the daily average for an adult is approximately 8,700 kJ).
