When Routines Break: The Health Implications of Disrupted Daily Life

Abstract

Disruptions to daily routines, such as those caused by holidays or the COVID-19 pandemic, have been linked to unhealthy changes in physical activity, sleep, and diet. The Structured Days Hypothesis (in children) and the Social Zeitgeber Model (in adults) provide theoretical frameworks that explain how routines influence lifestyle behaviors. Together, these models highlight daily routines as a modifiable behavioral risk factor that can promote healthier lifestyles. Integrating routine-building strategies into clinical practice, especially during times when routines are most vulnerable to disruption, represents a low-cost and scalable approach to health promotion. This article outlines practical strategies that health care providers can use to help patients establish and sustain daily routines.

Introduction

Daily routines refer to structured, recurring patterns of behavior, such as waking, eating, sleeping, and managing time, that help organize an individual’s day.^1,2 These routines contribute to a sense of coherence and predictability throughout the day, which can enhance psychological well-being by promoting a sense of control and self-efficacy.^3,4 Research has shown that individuals with lower levels of daily routine report higher levels of anxiety and depressive symptoms compared to those with more structured routines.^2,5-8 Beyond mental health, daily routines play a vital role in shaping modifiable behavioral risk factors, including physical activity, sleep, and dietary behaviors.^9-12 In children, consistent daily routines, such as the school day, are associated with healthy diet and activity behaviors.^9,10,13,14 In adults, higher levels of daily routine are linked to greater stability in sleep–wake and meal schedules, and therefore improved diet quality and sleep.^11,15-17 Importantly, growing evidence suggests that disrupted or inconsistent daily routines contribute to an increased risk of chronic conditions such as obesity, hypertension, metabolic syndrome, and cardiovascular disease.^9,18,19

In this issue, Reddy et al. discuss the protective effects of healthy lifestyle behaviors against the adverse outcomes of the COVID-19 pandemic and highlight intervention strategies aimed at reducing disease burden, morbidity, and mortality. ²⁰ The COVID-19 pandemic, which persisted for over three years, caused widespread and prolonged disruptions to daily life for both children and adults globally. Promoting structured daily routines during such challenging times may represent a cost-effective and scalable strategy to support overall health and well-being.^2,11,16,21 In the sections that follow, we provide further examples of how disruptions to daily routines have impacted key health behaviors, such as physical activity, sleep, and nutrition. We then discuss the potential mechanisms linking routine to health outcomes and conclude with recommendations for healthcare providers to incorporate routine-building strategies into patient consultations to promote healthy lifestyle behaviors.

The Impact of Daily Routine Disruptions on Health

The COVID-19 pandemic serves as a prominent example of how large-scale disruptions to daily routines can negatively impact health. During the pandemic, many individuals experienced abrupt changes to work schedules, exercise habits, sleep patterns, and other daily activities. ²² Numerous studies in adults have documented declines in physical activity, worsening mental health and well-being, disruptions in sleep, and a marked increase in screen time.^5,23-26 Among children and adolescents, there was a significant rise in overweight and obesity rates, accompanied by unhealthy shifts in diet, physical activity, and sleep behaviors.^9,10,27,28

While the pandemic may be viewed as a temporary crisis, similar disruptions to routine transpire on a recurring basis, particularly during extended holiday periods. For example, the holiday season (i.e., late November through early January) is commonly associated with an easing of daily structure, leading to irregular eating and sleep schedules, reduced physical activity, and increased sedentary behaviors.^29-31 Research shows that Americans gain nearly one pound during the holiday season. ³⁰ Although modest, this weight gain is often retained long-term and may account for over 50% of the annual weight gain in adults. ³⁰ A similar pattern is observed in children and adolescents, as weight gain tends to accelerate during the summer compared to the school year.^32-34 These patterns illustrate that even brief disruptions in daily routine, such as those occurring during holidays, can have meaningful implications for long-term health outcomes.

Underlying Mechanisms of How Daily Routines Influence Health Behaviors

The Structured Days Hypothesis and the Social Zeitgeber Model propose explanations for how consistent daily routines in both children and adults can foster healthy lifestyle behaviors and, in turn, promote overall well-being.^35,36 The Structured Days Hypothesis proposes that the consistent presence of structure and routine in a child’s day positively shapes their obesogenic behaviors. ³⁵ The Structured Days Hypothesis, found in the “filled-time perspective,” posits that time filled with favorable activities cannot be filled with unfavorable activities. ³⁷ For example, a routinized school day fills children’s time with classes (including physical education), recess and scheduled mealtimes, leaving less opportunity for prolonged screen use or excessive snacking. While children may still make unhealthy choices in school (e.g., choosing nutrient-poor foods over free school lunches),^38-40 the structured environment limits prolonged engagement in these behaviors (e.g., eating is not allowed during class). In contrast, less routinized days at home (e.g., weekends and summer breaks) afford greater freedom, and youth appear to opt for late bedtime and waketime, extended screen time, and unhealthy snacking, yielding (ultimately) accelerated BMI gain.^14,41 A systematic review of 296 studies supports this, showing that adolescents engage in more obesogenic behaviors on weekends and during summer compared to school days. ¹⁴

The Social Zeitgeber Model describes the critical role of social cues (zeitgebers, meaning “time-givers” in German) in regulating a person’s circadian rhythms, with disruptions to these cues negatively influencing mental and physical health. ³⁶ The human body’s internal clock is synchronized not only by light–dark cycles but also by social zeitgebers—time cues derived from routinized daily activities such as social interactions, mealtimes, bedtimes, and work or school. These cues act as reference points that help maintain stable biological rhythms, including the sleep–wake cycle. When such cues are disrupted—through events such as holidays or the COVID-19 pandemic—circadian rhythms can become misaligned. Alterations in the regularity of circadian rhythms have been linked to adverse health outcomes, including obesity and challenges in weight management.^42-44

Counseling Strategies for Promoting Daily Routine

Recognizing daily routine as a modifiable behavioral risk factor and incorporating routine-building strategies into clinical counseling represent practical approaches to support healthier lifestyles. To assist adult patients in establishing daily routines, healthcare providers should begin by assessing patients’ current daily structure and guiding them to regulate their day by setting consistent sleep and wake times, as well as organizing exercise and meal schedules around their individual commitments. ¹ During the planning phase, patients engage in implementation intentions, a self-regulatory process in which they specify the how, where, and when of performing desired behaviors.^45,46 This phase also involves exploring potential barriers such as work demands and family responsibilities, and collaboratively developing strategies to maintain routines despite such challenges. Patients should be equipped with contingency plans to address common disruptions—such as skipped activities or vacation periods—by identifying alternative actions in advance. This proactive approach enables patients to apply adaptive strategies automatically and minimize routine disruptions. Furthermore, healthcare providers should encourage patients to engage family members and friends in certain activities, as buddy systems can serve as powerful motivators to enhance adherence to scheduled activities.^47-50 Additionally, leveraging technology, including smartphone alerts, calendar notifications, and wearable devices (e.g., Apple Watch reminders for activity and sleep–wake times), can provide timely cues and foster accountability, thereby supporting routine maintenance.

For youth patients, healthcare providers play a vital role in informing caregivers about the benefits of structured programming in promoting consistent routines. Providers can emphasize how daily routines provided by structured programs, such as summer camps, extracurricular activities, or afterschool programs, support health and well-being, encouraging families to prioritize enrollment. Additionally, providers can assist families in overcoming participation barriers by connecting them with available community resources, financial assistance, and relevant local initiatives, advocating for equitable access.

Conclusion

Routine may appear ordinary, but it is a powerful determinant of healthy lifestyle behaviors. The Structured Days Hypothesis and the Social Zeitgeber Model illustrate how daily routines serve as protective structures that anchor physical activity, sleep, and diet. The COVID-19 pandemic provided a real-world example of how large-scale disruptions to routine can undermine these behaviors, with consequences for both physical and mental health. Although the pandemic has passed, recurring disruptions such as extended holiday periods produce similar ripple effects that can be substantial and long-lasting. Yet, it is precisely the ordinariness of routine that makes it such a promising strategy: it is low-cost, accessible, and modifiable. By empowering patients and families to establish and sustain routines, healthcare providers can leverage one of the simplest yet most effective strategies to promote healthier lifestyles and support long-term well-being.
