Ritmo circadiano

Autocuidado em Saúde: Alimentação e Atividade Física

A cada 24h o corpo vivencia o que é chamado de ciclo circadiano, controlado pelo nosso relógio biológico que gerencia mudanças hormonais, fisiológicas, mentais e comportamentais que são influenciadas pelo nascer e pôr do sol. E o estudo desses ritmos é chamado de cronobiologia, que estuda como o tempo e o ambiente influenciam nosso estado de saúde e nossa disposição. Entender como esse ritmo influencia nossa disposição nos ajuda a organizar a vida de uma forma mais produtiva, é como nadar com a maré. E aí, vamos aprender mais sobre isso?
