Sleepiness after a Meal
Have you ever felt sleepy after your meal?
食後の眠気
It is considered that this symptom is caused by a brain hormone “orexin.”
食後に眠気を感じたことはありませんか？
Humans secrete orexin when hungry, then they get the urge to eat something, and the wakefulness is promoted.
これは、脳内ホルモンの「オレキシン」が原因だと考えられています。
However, when the belly is full, the secretion amount of orexin will decrease, and it will make us feel sleepy.
人間は空腹になるとオレキシンが分泌され、何か食べたいと感じるようになり、同時に眠気を覚まします。
Therefore, you can keep wakefulness by skipping your meals, but don’t do that because it brings more harm than good.
しかし満腹になるとオレキシンの分泌が減り、眠くなります。
In order to increase the amount of orexin, and keep wakefulness, you should taste and enjoy your meals slowly over time.
そのため食事を抜けば眠くなりませんが、デメリットが大きいので抜いてはいけません。
