    O cérebro não tem um interruptor de liga e desliga; ele funciona como um computador complexo que precisa de uma sequência correta para o shutdown, e se você simplesmente puxa o cabo da tomada, o sistema corrompe.

    De acordo com Eli e Nia, isso ocorre porque o cérebro não possui um interruptor instantâneo de liga e desliga. Assim como um computador complexo, a mente exige uma sequência correta de desligamento para evitar que o sistema se corrompa. No silêncio do quarto, o volume dos problemas parece aumentar, fazendo com que o cérebro tente resolver pendências do dia ou preocupações futuras justamente no momento em que o corpo precisa de repouso.

    Um estudo da Universidade da Austrália do Sul, mencionado por Eli, mapeou o ritmo dos pensamentos e revelou que o cérebro de quem sofre com insônia demora muito mais para desengatar do modo diurno. Isso significa que, mesmo com o corpo cansado, a cabeça continua operando em um padrão de atividade elevado, dificultando a transição para o sono profundo e mantendo o estado de alerta indesejado.

    Os pensamentos invasivos, como revisar planilhas de trabalho ou lembrar de contas a vencer, criam uma espécie de 'motor ligado' dentro do crânio. Nia explica que essa sensação de tortura mental impede o relaxamento, pois a mente foca em detalhes do cotidiano e até em memórias antigas. Esse processo impede que o sistema entre no modo de 'shutdown' necessário, resultando em uma noite de sono fragmentada ou inexistente devido ao estresse.
