7/ Our brain could power a 25 watt bulb
When we are awake, our brain could produce enough energy to power a 25 watt light bulb. Things are hotting up!
8/ Yawning helps cool down your brain
Yawning can be triggered by your brain heating up, and our brains use 40% of our energy. To avoid overheating it, we yawn to cool everything down!
9/ A lack of sleep heats up your brain
And slows it down terribly, increasing the risk of damage over time.
10/ Regular exercise can increase your grey matter
Getting regular physical exercise can increase the grey matter in your hippocampus.
11/ Einstein’s brain was smaller than average
Albert Einstein’s brain was smaller than other brains (1.23 kg compared to 1.4 kg for a normal brain). But it is likely to have contained more glial cells, which allow for reflection.
12/ Women generally have smaller brains than men
But that doesn’t mean they are any less intelligent, if you have learned anything from the previous point on Einstein! Even if they aren’t the same size, feminine and masculine brains produce equal performance levels on intelligence tests.
