“…89 Elevated scores on affective states, arousal and the trait of neuroticism have been related to higher levels of perceived sleepiness. 90 NA and neuroticism are highly correlated; 91 thus, high NA scores probably reflect neuroticism to a certain extent. Slavish et al 92 substantiated this interpretation by showing that the effect of neuroticism on sleep disturbances became non-significant when controlling for NA.…”

The discovery of intrinsically photosensitive retinal ganglion cells in the eye and their interaction with melatonin has shown that light has significant effects beyond vision. The present study compared the effect of an integrative lighting system, providing low-intensity melanopic illuminance with the effect of an ordinary, qualitatively equivalent, electric lighting system. The study utilised a 2 × 7 randomised mixed experimental design. The sample consisted of 13 women and 11 men. Salivary melatonin secretion and subjectively perceived sleepiness in the evening were measured every half hour during 3 hours of light exposure. The chronobiologic typology (stability and amplitude) and trait-like negative and positive affect were measured once and analysed as covariates. The results showed a general increasing linear effect for both melatonin and sleepiness. A significant nonlinear effect of time was present in the group exposed to integrative lighting, indicating delayed melatonin secretion. The findings were stable across all levels of the examined covariates. These results confirm that the integrative lighting system produces effects beyond vision under otherwise ordinary lighting conditions. Furthermore, the results corroborate research suggesting that melatonin secretion and sleepiness may not be directly linked. The integrative lighting system provides new opportunities to develop indoor electric lighting resembling daylight.

“…Em um ambiente acadêmico, onde a sobrecarga de estudos, trabalhos e atividades extracurriculares é a norma, a SDE torna-se uma condição comum e impactante. A pontuação total na escala varia de 0 a 24 pontos, sendo que uma pontuação mais elevada indica maior probabilidade de SDE (MARQUES et al, 2020).…”

A sonolência diurna em estudantes universitários, especialmente em cursos desafiadores como Medicina, representa uma preocupação significativa, impactando o desempenho acadêmico e a qualidade de vida. Este estudo foca na avaliação da sonolência diurna em acadêmicos de medicina da Zona da Mata Mineira, utilizando a Escala de Sonolência de Epworth (ESE). A ESE, composta por oito itens, revela-se uma ferramenta valiosa para identificar a sonolência diurna excessiva (SDE). Resultados indicam que quase metade da amostra apresenta SDE, associada a fatores demográficos como gênero e faixa etária. A detecção precoce por meio da ESE permite orientar os estudantes para intervenções adequadas, promovendo melhorias na qualidade de vida e desempenho acadêmico.
