“…Moreover, we also observed that sleeping features are highly correlated within a couple. This correlation is stronger during when the couple’s child is younger but dilutes at 6 years of age postpartum in our data, confirming that couples tend to have similar chronotype and sleeping habits in the earliest phases of their relationship, as already observed by other studies [ 3 ]. On one hand, within couple correlations of midpoint of sleep, time of getting out of bed and sleep onset are positive and particularly strong, especially during free days.…”

“…Firstly, couples tend to have similar chronotype and sleeping habits [ 2 ]. Secondly, the chronotype similarity positively affects the partnership relationship between the two people in the couple [ 3 ]. Furthermore, the association between chronotype similarity and relationship satisfaction operates as a function of the relationship stage.…”

The Parent’s Chronotype and Child’s Sleeping Quality in Association with Relationship Satisfaction

et al. 2020

The prospective Ulm-SPATZ study was investigated to assess the role of child sleeping quality between 4 to 6 years of age in affecting a partner’s sleeping and relationship satisfaction within a couple. The study was conducted using a triadic approach in which the child was included in the Actor-Partner-Interdependence Model (APIM). Sleeping quality of the child was determined by using the German version of the children’s sleep habits questionnaire, sleeping features of the parents were assessed by using the Munich chronotype questionnaire, and the partner relationship assessment was performed by employing the German version of the parenting stress index questionnaire. In 211 German triads, we observed that sleeping characteristics and partner relationship scores at different child ages are consistent for both men and women. Higher and statistically significant sleep duration, time spent in bed, the midpoint of sleep, time getting out of bed, and sleep onset in women compared to men during the working days were observed. The APIM analyses showed a significant direct effect of child sleep quality on the partner relationship satisfaction. In women, a mediated effect of child sleep quality acted through sleep duration and time spent in bed on the partner relationship satisfaction score during both free and working days. In men, low child sleep quality was found to be associated with increased sleep onset during both free and working days. Child sleep quality influences relationship satisfaction mostly in mothers, likely because of their higher involvement in childcare during working days. Distress in the couple could be counteracted by a major involvement of the fathers in child management.

“…Another aspect to consider is sexual opinion. Attitudes towards sexuality are related to morning or evening preferences [ 17 , 18 ]. The erotophobia–erotophilia dimension, both of which are a learned disposition to respond to sexual stimuli, is used to measure sexual opinion.…”

“…The erotophobia–erotophilia dimension, both of which are a learned disposition to respond to sexual stimuli, is used to measure sexual opinion. Erotophobia entails the response with more negative attitudes towards the sexual stimulus and feelings of avoidance, and erotophilia is an opinion contrary to erotophobia, a positive attitude towards the sexual stimulus, with more favourable emotions and evaluations leading to a greater search for sexual stimuli [ 17 , 18 , 19 ]. There seems to be a higher evening peak of sexual activity and desire [ 20 ].…”

Associations between Chronotype, Adherence to the Mediterranean Diet and Sexual Opinion among University Students

et al. 2020

A person’s chronotype determines different habits, among which are eating and physical activity. Furthermore, at the university stage, social and organisational factors have a direct effect on students’ daily attitudes and habits. Adherence to the Mediterranean diet is linked to better sleep quality and less social jet lag, but association with chronotype or sexual opinion remains unclear. The aim of this study was to assess the associations between chronotype, adherence to the Mediterranean Diet, and sexual opinion. A multicentre observational study enrolled 457 students, from the University of Castilla-La Mancha and the University of Cordoba. Sociodemographic data and adherence to the Mediterranean diet, chronotype, physical activity, and sexual opinion were collected with validated questionnaires. The study period was from December 2017 to January 2018. Our results reported that students with an evening chronotype (E-type), with evening preferences, had a lower adherence to the Mediterranean diet and showed a higher tendency towards erotophilia. E-type students reported a significantly lower intake of fruits, vegetables, pulses, cereals, and olive oil, and higher breakfast skipping. Therefore, among the measures to promote healthy habits (obesity prevention, sexual education, socialisation, etc.), chronotype and an analysis of the impact of the schedules established by the universities must be considered.

“…During night-time, after the working hours, individuals are at their peak tiredness. This disrupts self-regulation and predisposes to impulsive behaviors, succumbing to immediate pleasures, such as cravings for food ( Sevincer et al, 2016 ), alcohol and club/party drug use ( Millar et al, 2019 ), and sexual intercourse ( Refinetti, 2005 ; Jocz et al, 2018 ). Indeed, evening-oriented individuals have lower self-control ( Digdon and Howell, 2008 ), which mediates their higher present orientation and instant gratification ( Milfont and Schwarzenthal, 2014 ), are more impulsive ( Cross, 2010 ), are more hedonistically present-oriented ( Nowack and Van Der Meer, 2013 ; Stolarski et al, 2013 ; Borisenkov et al, 2019 ), use more alcohol and club/party drugs ( Millar et al, 2019 ), and tend to smoke more ( Randler, 2008 ; Wittmann et al, 2010 ; Patterson et al, 2016 ) than other chronotypes.…”

COVID-19 Pandemic on Fire: Evolved Propensities for Nocturnal Activities as a Liability Against Epidemiological Control

et al. 2021

Humans have been using fire for hundreds of millennia, creating an ancestral expansion toward the nocturnal niche. The new adaptive challenges faced at night were recurrent enough to amplify existing psychological variation in our species. Night-time is dangerous and mysterious, so it selects for individuals with higher tendencies for paranoia, risk-taking, and sociability (because of security in numbers). During night-time, individuals are generally tired and show decreased self-control and increased impulsive behaviors. The lower visibility during night-time favors the partial concealment of identity and opens more opportunities for disinhibition of self-interested behaviors. Indeed, individuals with an evening-oriented chronotype are more paranoid, risk-taking, extraverted, impulsive, promiscuous, and have higher antisocial personality traits. However, under some circumstances, such as respiratory pandemics, the psychobehavioral traits favored by the nocturnal niche might be counter-productive, increasing contagion rates of a disease that can evade the behavioral immune system because its disease cues are often nonexistent or mild. The eveningness epidemiological liability hypothesis presented here suggests that during the COVID-19 pandemic, the evening-oriented psychobehavioral profile can have collectively harmful consequences: there is a clash of core tendencies between the nocturnal chronotype and the recent viral transmission-mitigating safety guidelines and rules. The pandemic safety protocols disrupt much normal social activity, particularly at night when making new social contacts is desired. The SARS-CoV-2 virus is contagious even in presymptomatic and asymptomatic individuals, which enables it to mostly evade our evolved contagious disease avoidance mechanisms. A growing body of research has indirectly shown that individual traits interfering with social distancing and anti-contagion measures are related to those of the nocturnal chronotype. Indeed, some of the social contexts that have been identified as superspreading events occur at night, such as in restaurants, bars, and nightclubs. Furthermore, nocturnal environmental conditions favor the survival of the SARS-CoV-2 virus much longer than daytime conditions. We compare the eveningness epidemiological liability hypothesis with other factors related to non-compliance with pandemic safety protocols, namely sex, age, and life history. Although there is not yet a direct link between the nocturnal chronotype and non-compliance with pandemic safety protocols, security measures and future empirical research should take this crucial evolutionary mismatch and adaptive metaproblem into account, and focus on how to avoid nocturnal individuals becoming superspreaders, offering secure alternatives for nocturnal social activities.
