Seasonal Variation in the Responsiveness of the Melanopsin System to Evening Light: Why We Should Report Season When Collecting Data in Human Sleep and Circadian Studies

Clocks & Sleep, 2023
It is well known that variations in light exposure during the day affect light sensitivity in the evening. More daylight reduces sensitivity, and less daylight increases it.

Time-on-task decrement in vigilance is modulated by inter-individual vulnerability to homeostatic sleep pressure manipulation

Frontiers in Behavioral Neuroscience, 2014
Under sleep loss, vigilance is reduced and attentional failures emerge progressively. It becomes difficult to maintain stable performance over time, leading to growing performance variability (i.e.

Chronobiological Aspects of Narcolepsy [PDF]

Sleep, 1994
The circadian, circasemidian and ultradian features of sleep-wake patterns in narcolepsy are reviewed with respect to the hypotheses that chronobiological disturbances might either be specific to the condition or contribute to its symptomatic profile.

Is the association of chronotype with adolescent behavior problems mediated through social jetlag?

, 2023
9 páginasWe examined the associations of chronotype with behavior problems in a cross-sectional study of 957 Colombian adolescents (mean age, 14.6 years; 56% female), in addition to the mediating role of social jetlag.

Chronobiology and its Ayurvedic Understanding

, 2023
Rhythm is an essential component of life. Chronobiology is a branch of biology concerned with biological rhythms i.e., the time related phenomena in living organisms. It is a relatively young and fast evolving research field.

Desynchronised times? Chronobiology, (bio)medicalisation and the rhythms of life itself

, 2021
This paper takes a critical look at the role of chronobiology in society today, with particular reference to its entanglements with health and medicine and whether or not this amounts to the (bio)medicalisation of our bodily rhythms.

Comment la chronobiologie est-elle possible ? La durée et la science contemporaine

Bergsoniana
By focusing on the mechanisms that allow living beings to synchronize with their environment, chronobiology is based on the notion of time more than biology had ever done before. But what concept of time this branch of biology presupposes?

Circadian cuisine in synchronizing holistic nutrition and biological rhythms

World Nutrition
Chronobiology is an emerging area of research exploring the complex relationship between circadian rhythms and nutrition. This review discusses the interplay of chronobiology and overall nutrition. In simpler terms, the time we eat affects our nutrition

The effect of urbanization on sleep, sleep/wake routine, and metabolic health of residents in the Amazon region of Brazil

, 2020
Studying communities with different levels of urbanization may further the understanding of risk factors underlying metabolic diseases. The present study is unique by comprising detailed assessment of sleep and activity, biological rhythms, and metabolic
