“…Consuming caffeine may be viewed as an adaptive strategy, however, as it has been found to shift the phase of circadian rhythm in mammals and humans [Bonnet et al, 1979;Ehret et al, 1975] and to reduce daytime sleepiness after sleep restriction [Lumley et al, 1987]. More extensive use of coffee and tea has also been reported for E-types in other studies [e.g., Ishihara et al, 1985].…”

Developmental perspectives on sleep/wake rhythmicity have been neglected in research, yet evidence from chronobiological sources, infant sleep data, and adult light treatment studies suggest continuities in individual differences in internal synchronization to light-dark cycles. Developmental systems suggest maintenance through strong contextual constraints, perturbed only by unusual alterations in social demands and light exposure, such as shift work. Retrospective data from university students, employing the Morningness-Eveningness Questionnaire (MEQ), supported predicted continuity of sleep/wake patterns and associated states of alertness and fatigue as a function of time of day as well as relations with different patterns of social interactions with parents over daily routines in childhood and adolescence. Eveningness is related to greater difficulty meeting familial and social demands for morning performance than Morningness.

“…Short sleep is associated with current or former smoking status [31, 32] while both short and long sleep are associated with higher cigarette consumption [31, 33]. Tobacco use is more prevalent among late chronotypes in adults [34–36] and adolescents [37, 38]. Smokers have also been shown to have delayed sleep onset as compared to non-smokers, [39] which can promote late chronotype.…”

Smoking, Screen-Based Sedentary Behavior, and Diet Associated with Habitual Sleep Duration and Chronotype: Data from the UK Biobank

Background Sleep duration has been implicated in the etiology of obesity but less is known about the association between sleep and other behavioral risk factors for cardiovascular disease. Purpose The aim of this study was to examine the associations among sleep duration, chronotype, and physical activity, screen-based sedentary behavior, tobacco use, and dietary intake. Methods Regression models were used to examine sleep duration and chronotype as the predictors and cardiovascular risk factors as outcomes of interest in a cross-sectional sample of 439,933 adults enrolled in the UK Biobank project. Results Short sleepers were 45 % more likely to smoke tobacco than adequate sleepers (9.8 vs. 6.9 %, respectively). Late chronotypes were more than twice as likely to smoke tobacco than intermediate types (14.9 vs. 7.4 %, respectively). Long sleepers reported 0.61 more hours of television per day than adequate sleepers. Early chronotypes reported 0.20 fewer daily hours of computer use per day than intermediate chronotypes. Early chronotypes had 0.25 more servings of fruit and 0.13 more servings of vegetables per day than late chronotypes. Conclusions Short and long sleep duration and late chronotype are associated with greater likelihood of cardiovascular risk behaviors. Further work is needed to determine whether these findings are maintained in the context of objective sleep and circadian estimates, and in more diverse samples. The extent to which promoting adequate sleep duration and earlier sleep timing improves heart health should also be examined prospectively.

“…The ''mid-sleep on free days''-i.e., the ''half-time'' or ''median'' of the sleep phase expressed in hours of zeitgeber time [ZT]-has been introduced as a convenient quantitative measure of the chronotype (Roenneberg et al, 2003;Zavada et al, 2005), and it has been shown in large demographical surveys that there is a multitude of risk factors and disease prevalences that correlate with the chronotype (Ishihaka et al, 1985;Levandovski et al, 2011;Roenneberg et al, 2012;Wittmann et al, 2006).…”

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 sleep phase. Demographically, early and late human chronotypes differ with respect to the stability of their rhythms and the prevalence of several widespread diseases and risk factors, such as depression, nicotine abuse, and others. Inbred mice are widely used in chronobiological research as model organisms, but up to now there was no way to chronotype them. We have developed a method to chronotype mice in hours and fractions of hours by measuring the median of activity (MoA) and have shown that different mouse strains have significantly different MoAs and, thus, chronotypes. We have further developed methods to estimate the stability of the behavioral rhythms and found that "late" mice have relatively instable rhythms. Our methods permit the use of inbred mice for investigations into the molecular and genetic background of the chronotype and the prevalence of risks and diseases that are associated with it.
