You will become a cow if you lie down soon after eating.

There is a famous superstition in Japan as the following:

"You will become a cow if you lie down soon after eating."

In fact, I was also taught like that.

I have no idea why it is a cow, but I think that it says "you will get fat like a cow."

Lying down soon after eating is regarded as a bad manner in Japan.

Therefore, in order to admonish such behavior, this superstition was born.

However, according to a medical study, lying down for about 30 minutes soon after eating is good for your health -- it will play a role in the digestive process.

食べた後すぐ寝ると牛になる

日本には、次のような有名な迷信があります。

「食べた後すぐ寝ると牛になる」

実際、私もそのように教わりました。

何故「牛」かはよくわかりませんが、「牛のように太るぞ」ということを言っているのだと思われます。

食べてすぐ寝るのは行儀が悪いとされているため、そのような行為を戒めるためにこの迷信が作られました。

しかし、医学的な観点からすると、食後は30分ほど横になって寝たほうが、消化に良いそうです。
