saúde

Além de suas habilidades conhecidas, cães ajudam a acalmar pessoas traumatizadas. Eles respondem a pistas físicas de flashbacks, proporcionando conforto e lembrando que o ambiente é seguro.

saúde

Estudo da Universidade Dalhousie, Nova Escócia, publicado na Frontiers in Allergy, investigou se cães podem ajudar pessoas com TEPT antes de flashbacks, similar a intervenções pré-convulsões.

saúde

Cientistas analisaram o hálito de 26 participantes, antes e após lembrar traumas. Os cães foram treinados para farejar diferenças entre amostras de hálito calmo e estressado.

saúde

Um cão distinguiu amostras 81% das vezes, e outro 74%. Isso mostra a capacidade dos cães em identificar estados emocionais através do hálito.

saúde

Pesquisadores acreditam que um cão detectou substâncias químicas relacionadas à vergonha e outro à ansiedade, mostrando diferentes percepções do que constitui um hálito "estressado".

saúde

Um cão sintonizou-se com hormônios adreno-medulares (adrenalina), enquanto outro focou em hormônios hipotálamo-hipófise-adrenais (cortisol).

saúde

Os pesquisadores reconhecem que este é um estudo de prova de conceito. São necessários estudos maiores para confirmar esta habilidade em cães.

saúde

Resultados indicam potencial dos cães em identificar e responder a sinais de TEPT, podendo ser usados como ferramenta terapêutica adicional para pessoas com trauma.

saúde

Com mais pesquisas, essa habilidade canina pode ser aproveitada para desenvolver novos métodos de assistência para pessoas com transtornos emocionais, melhorando sua qualidade de vida.
