Chronotypes and oxidative stress: is there an association? [PDF]

Biological Rhythm Research, 2012
Human studies suggest that free radicals and antioxidant enzymes can alter according to age, lifestyle, environment, and habits. Individuals having a marked circadian preference, that is, morning type or evening type, differ on a number of psychological, behavioral, and biological variables.

Chronotype, sports and public health

Chronobiology International, 2015
“Chronotype”, addressed in the Journal in 1997 (Tassi & Pins, 1997) and in 38 publications since 2014 (Broms et al., 2014; Erren & Morfeld, 2014; Laborde et al., 2015; Vitale et al., 2015) alone, i...

Sleep and Chronotype for Children in Japan

Perceptual and Motor Skills, 1999
To investigate the change in sleep-wake habits, Morningness-Eveningness preference, and sleep status by grade, 512 students aged from 6 to 18 years, were tested using the Morningness-Eveningness Questionnaire and Sleep Questionnaire. The habitual waking time showed no difference by grade, but the students above Grade 7 reported a significantly later ...

Human chronotypes in the North

Human Physiology, 2010
Long-term exposure to the climatic and social factors of the North cause desynchronization of the human circadian system, which can lead to an increase in the risk of age-associated diseases. Earlier, on a small sample, I showed that the higher the latitude at which a person resides in the North, the higher the frequency of the late chronotype.

Influence of Nocturnal Asthma on Chronotype

Journal of Asthma, 2008
Individual differences in circadian rhythm have been studied since the past century. Chronotypes are a chronobiology classification based on the preferential times for beginning and ending activities throughout the day. Chronotypes can be classified as definitely morning, moderately morning, indifferent, moderately evening, and definitely evening.

Chronotypes and rhythm stability in mice

Chronobiology International, 2013
Humans come in different chronotypes: The phase of their sleep-wake cycle with respect to the phase of the external, sidereal cycle of night and day differs. Colloquially, the early chronotypes are addressed as "larks," the late ones as "owls." The human chronotype can be quantified in hours and minutes of local time by determining the median of the ...

Chronotypes in elite Japanese athletes: assessed by the reduced Morningness-Eveningness and Munich ChronoType Questionnaires

Chronobiology International, 2021
This study aimed to test in elite athletes the correlation between the chronotype determined by the reduced version of the Morningness-Eveningness Questionnaire (rMEQ) and that determined by the Munich ChronoType Questionnaire (MCTQ). In total, 351 elite athletes filled out the rMEQ questionnaire, 59 athletes filled out the MCTQ questionnaire, and 39 ...

Nightmares Associated with the Eveningness Chronotype

Journal of Biological Rhythms, 2010
Relations between common nightmares and chronobiological factors remain poorly understood. The possibility that nightmare frequency and distress are associated with chronotype (“morningness-eveningness”) was investigated in a sample of respondents to an Internet questionnaire. Over a 4½-year period, a total of 3978 subjects (mean age = 26.5 ± 11.6 yrs;

Chronotype and the Transition to College Life

Chronobiology International, 2011
Social synchronizers of morningness-eveningness, or chronotype, begin to change during the developmental transition from adolescence to college life. The current study examined how these changes related to the sleep/wake patterns of 220 undergraduates (93 males/122 females) ranging in age from 18 to 29 yrs at a private university.
