Por que bocejamos depois que alguém boceja - Nexo Jornal
Sim, do reino animal. O que significa que os animais de estimação também bocejam. Algo que você certamente já viu se tem gatos ou cães em casa. Mas isso não é tudo. A maioria dos animais com coluna vertebral faz isso: aves, crocodilos, tartarugas… Até mesmo os peixes! Além disso, descobriu-se recentemente que os peixes contagiam-se com os bocejos.
E essa é uma das características mais notáveis desse fenômeno: seu contágio. Mas acontece que nós, seres humanos, não apenas bocejamos ao ver alguém bocejar. Simplesmente ler sobre bocejos ou pensar neles já pode provocá-los. A questão então é: por que eles "pegam" com tanta facilidade?
Abrindo a boca com os primeiros bocejos
O verbo «bocejar» deriva do latim oscitāre, que significa abrir a boca (o gesto mais característico). Uma vez a boca aberta, o bocejo avança com a inevitabilidade de um espirro. Ou seja, quando começa, não dá para parar.
