Close friends and family are more likely than acquaintances or strangers to catch someone yawning, Livescience.com reported.

While yawns do not seem to have a connection with any particular emotion (unlike, say, smiles, which could indicate happiness), in some ways we are forming an emotional connection by mimicking a yawn, Matthew Campbell of Emory University said.

打哈欠多在朋友間傳染

???????據熱點科學網站報道，一項新的研究表明，一個人如果打了一個哈欠，他的親密朋友和家人比其他人或陌生人更容易跟著打。

???????通過跟著對方打哈欠，我們能更好地理解和感覺對方有多辛苦，或者說多無聊。
