Question

Did you know? Your brain uses about 20 watts — the same as an energy-saving bulb. Although it accounts for only 2% of your body weight, it consumes 20% of your total energy. Thinking does not measurably cost more than staring blank — "mental fatigue" is more about motivation than calories.

Accepted Answer

Your brain uses about 20 watts — the same as an energy-saving bulb. Although it accounts for only 2% of your body weight, it consumes 20% of your total energy. Thinking does not measurably cost more than staring blank — "mental fatigue" is more about motivation than calories.

Je hersenen verbruiken ongeveer 20 watt — net zoveel als een spaarlamp. Hoewel ze maar 2% van je lichaamsgewicht zijn, slokken ze 20% van je totale energie op. Denken kost niet meetbaar meer dan staren in het niets — de "denkmoeheid" zit eerder in motivatie dan calorieën.
