Menstrual disturbances and its association with sleep disturbances: a systematic review

Abstract

Background

Menstrual disturbances harm women’s health, and general well-being. As growing evidence highlights the relationship between sleep and menstrual disturbances, it is imperative to comprehensively examine the association between sleep and menstrual disturbance considering the multiple dimensions of sleep. This systematic review aims to identify the association between sleep and menstrual disturbances by evaluating using Buysse’s sleep health framework.

Methods

A comprehensive search of the literature was conducted in PubMed, EMBASE, psychINFO, and CINAHL to identify publications describing any types of menstrual disturbances, and their associations with sleep published between January 1, 1988 to June 2, 2022. Quality assessment was conducted using the Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies. The findings were iteratively evaluated menstrual disturbances and their association with sleep using Buysse’s sleep health framework. This framework understands sleep as multidimensional concept and provides a holistic framing of sleep including Satisfaction, Alertness during waking hours, Timing of sleep, Efficiency, and Sleep duration. Menstrual disturbances were grouped into three categories: premenstrual syndrome, dysmenorrhea, and abnormal menstrual cycle/heavy bleeding during periods.

Results

Thirty-five studies were reviewed to examine the association between sleep and menstrual disturbances. Premenstrual syndrome and dysmenorrhea were associated with sleep disturbances in sleep health domains of Satisfaction (e.g., poor sleep quality), Alertness during waking hours (e.g., daytime sleepiness), Efficiency (e.g., difficulty initiating/maintaining sleep), and Duration (e.g., short sleep duration). Abnormal menstrual cycle and heavy bleeding during the period were related to Satisfaction, Efficiency, and Duration. There were no studies which investigated the timing of sleep.

Conclusions/Implications

Sleep disturbances within most dimensions of the sleep health framework negatively impact on menstrual disturbances. Future research should longitudinally examine the effects of sleep disturbances in all dimensions of sleep health with the additional objective sleep measure on menstrual disturbances. This review gives insight in that it can be recommended to provide interventions for improving sleep disturbances in women with menstrual disturbance.

Background

Menstrual disturbances are a significant health concern for women of reproductive age. In the United States, more than 4.5 million women of reproductive age suffer from at least one gynecological disturbance related to menstruation [1]. The common types of menstrual disturbances include premenstrual syndrome (PMS), dysmenorrhea (painful menstrual periods), heavy menstrual bleeding, and irregularities in the menstrual cycle in women of reproductive age [2–4]. PMS is a discomfort in the late-luteal phase (i.e., premenstrual phase) including emotional, behavioral, and physical symptoms [2, 5]. It is estimated that almost half of women of reproductive age (47.8%) considerably suffer from PMS [6] and approximately 20% experience premenstrual dysphoric disorder (PMDD), which is a moderate to severe form of PMS [7, 8]. Dysmenorrhea is reported by 66.6% of women of reproductive age. Heavy menstrual bleeding, which is defined as excessive menstrual blood loss of more than 80 mL per cycle [9, 10] and irregular menstrual cycle (no menstruation or menstrual interval of less than 21 days or more than 35 days) [11] account for up to one-third of gynecologic office visits [12].

Menstrual disturbances are severe enough to disrupt women’s physical, social, and emotional quality of life. Women with PMS and PMDD experience substantial emotional distress, functional impairments, and decreased quality of life [8, 13], which leads to increased risk of suicidality [14]. Dysmenorrhea may increase the risk of other chronic pains and reduce women’s health-related quality of life [15–17]. Heavy menstrual bleeding can indicate other gynecological disease, such as endometriosis [10, 18]. Untreated heavy menstrual bleeding can interfere with the daily life activities and quality of life of women [19]. Menstrual regularity is known as an indicator of women’s reproductive health and menstrual irregularity is reported to increase several medical conditions, such as infertility, diabetes mellitus, and endocrine disorder [5, 10, 20]. Promptly preventing and treating these menstrual disturbances has the potential to increase the overall quality of life in women of reproductive age.

Although the etiology of menstrual disturbances is unclear, focusing on sleep as a preventive measure of menstrual disturbances can be beneficial because disrupted sleep, such as poor sleep quality, difficulty initiating or maintaining sleep, or short sleep duration are apparent in women who suffer from menstrual disturbances [3, 10, 11, 15, 21–23]. Previous studies have found that each sleep characteristic, including sleep quality, efficiency, and duration, is independently associated with menstrual disturbances. However, it is important to note that our sleep is characterized by more than one characteristic, and each of sleep characteristics is simultaneously present in all individuals [24, 25]. Thus, it is needed to understand the role of multidimensional aspects of sleep in menstrual disturbances.

The Buysse’s framework of sleep health is useful for understanding sleep as a multidimensional concept [24]. This concept provides a holistic framework for sleep; Satisfaction, Alertness during waking hours, Timing of sleep, Efficiency, and Sleep Duration. The framework can provide a comprehensive understanding of the association between sleep and specific health outcomes, such as obesity, substance use, mental health, cardiovascular disease, and neurodegenerative disease [24, 26, 27]. Thus, this systematic review aims to (a) identify the association between sleep and menstrual disturbances by evaluating using the Buysse’s sleep health framework, and (b) describe gaps in the literature on the relationship between these phenomena in the reviewed studies. This review highlights the role of sleep as a modifiable factor in menstrual disturbances and provides basic knowledge of whether assessing and treating sleep is effective in reducing menstrual disturbances in women of reproductive age.

Methods

Based on the purpose of the study, inclusion and exclusion criteria are described below and the entire study selection process and the rationales for exclusion are shown in Fig. 1. This systematic review follows the protocol of Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines [28]. This study was registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42022308008).

Search strategies

Studies were selected from searches in four biomedical electronic databases: PubMed, EMBASE, psychINFO and CINAHL. Articles published from January 1, 1988 to June 2, 2022, were included, as 1988 was the first year that the association between menstrual disturbances and sleep appeared in literature. The following key words and combinations were used: (“dyssomnias” OR “sleep” OR “sleep disorder” OR “sleep disturbance” OR “sleep wake disorder”) AND (“menstruation disturbances” OR “menstruation disturbance” OR “menstrual disorders” OR “irregular menstruation” OR “irregular menstruation” OR “menstrual irregularity” OR “menstrual dysfunction”). The search strategy was developed in consultation with a health science librarian. The complete search strategy is provided in Additional file 1. In addition, in order to identify relevant articles missed by the previous search, the citation lists of selected articles were reviewed.

Eligibility criteria

Studies were included if they (1) were written in English; (2) published in a peer-reviewed journal; (3) data-based articles; (4) included healthy childbearing adult women (greater than 18 years old) as the study population; and (5) examined any type of menstrual disturbances, and their associations with sleep. Studies were excluded if they (1) focused on adolescent female and menopausal women; and (2) were not original articles (e.g., review paper, commentary, gray articles including dissertation, conference paper, abstract or editorials).

Data extraction and synthesis

Initial screening was independently conducted by the two authors (JB and BJ) through reading titles and abstracts based on the eligibility criteria. Potentially relevant articles retrieved from initial screening were proceeded to full text review. The two authors (JB and BJ) read the full texts of potentially relevant articles and discussed any concerns or discrepancies in the inclusion of articles. After reading articles in full text, the selected articles were analyzed by two independent authors (JB and BJ). One researcher conducted the data extraction (JB) and the extracted data was checked by the other researcher (BJ). Data from the selected articles was organized under the following headings: first author; year; location; sample details (sample size, age); research design; measures for sleep; measures for menstrual disturbances; and study findings. Extracted data were presented in tabular format and arranged sequentially by alphabet (Table 1). The findings were iteratively evaluated menstrual disturbances and their association with sleep using Buysse’s sleep health framework [24]. Articles were clustered based on the type of menstrual disturbances: (1) PMS and sleep health; (2) dysmenorrhea and sleep health; and (3) Abnormal menstrual cycle/bleeding and sleep health (Table 2).

Sleep health framework

Buysee’s sleep health framework consists of five dimensions of sleep (SATED: Satisfaction, Alertness during waking hours, Timing of sleep, Efficiency, and Sleep Duration) to understand specific dimensions of sleep and its association with specific health outcomes [24]. Five dimensions in Buysse’s sleep health framework were applied to comprehensively understand the association between specific dimensions of sleep and menstrual disturbances. Satisfaction is defined as: (1) the subjective assessment of good or poor sleep; and (2) amounts of slow wave sleep (SWS) or delta activity during sleep measured by polysomnography. The amounts of SWS or delta activity during sleep is correlated with sleep quality [24]. Alertness during waking hours is the ability to maintain attentive wakefulness. Daytime sleepiness reduces alertness during waking hours. Timing of sleep is where sleep is placed within the 24-hour day. Efficiency is the ease of falling asleep and/or returning to sleep. Increased wake after sleep onset or sleep latency is associated with lower sleep efficiency, and with the subjective assessment of insomnia symptoms including difficulty initiating sleep, difficulty maintaining sleep, or early morning awakenings, which are included in the dimension of efficiency. Duration is the total number of hours of sleep obtained per 24 h [24].

Study quality assessment

The quality assessment of the included studies was performed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Analytical Cross-Sectional Studies [29]. The JBI tool was selected as an assessment tool because most eligible studies included in this review had a cross-sectional design. Only one study had prospective longitudinal design [11]. Two authors (JB and BJ) independently assessed the quality of the included studies. Any disagreements were resolved through group discussions. The JBI tool consists of eight items evaluating methodological concepts such as participant inclusion criteria, measurement validity and reliability, confounding factors, and appropriate statistical analysis. The items were answered with three possible response categories (yes, no or unclear). An overall score was calculated for each included study by summing the number of “yes” responses. The maximum score was 8. A score of 1–4 was considered as low quality, from 5 to 6 as moderate and 7–8 as high quality [30]. No studies were excluded based on methodological quality.

Results

A total of 35 studies were identified evaluating the association between menstrual disturbances (PMS and/or dysmenorrhea and/or abnormal menstrual cycle/heavy bleeding during periods) and sleep. Among menstrual disturbances, PMS extensively includes premenstrual dysphoria, premenstrual related negative affect symptoms, and PMDD. The identified studies were conducted in the multiple countries, including the United States, Canada, the Republic of South Africa, Australia, Taiwan, Turkey, Pakistan, India, Singapore, Malaysia, Iran, Brazil, Korea, Saudi Arabia, Ethiopia, Egypt, Ireland, and Japan. The sample size in the studies ranges between 9 and 11,648. Although most studies presented the mean ages or range of ages in study participants [10, 13, 15, 21, 22, 31–56], two studies did not have any information of age [57, 58], and two studies only reported approximate age in study participants [11, 59].

Detailed characteristics of study participants and measures of sleep and menstrual disturbances (PMS, dysmenorrhea, abnormal menstrual cycle/heavy bleeding during periods) are described in Table 1. While most studies explain how to measure menstrual disturbances, one study did not explain how to measure abnormal menstrual cycle [54] and one study measured menstrual disturbances comprehensively (having PMS and/or dysmenorrhea and/or abnormal menstrual cycle/heavy bleeding) [38]. One study evaluated sleep for PMS and dysmenorrhea [40]; one study for PMS and abnormal menstrual cycle [41]; one study for abnormal menstrual cycle and heavy bleeding [10] nineteen studies for PMS only [13, 32, 34–36, 39, 42, 43, 46, 48, 50–53, 55–59]; seven studies for dysmenorrhea only [15, 22, 31, 33, 37, 44, 45]; four studies for abnormal menstrual cycle only [11, 21, 47, 49].

Table 2 provides a detailed description of the sleep disturbances classified by related sleep health dimensions included in this review. Sleep quality issues (Satisfaction) were reported in most of the studies (66%), while other sleep characteristics including daytime sleepiness (Alertness during waking hours), the ease of falling asleep and/or returning to sleep (Efficiency), insomnia symptoms (Efficiency), and sleep duration (Duration) were reported in approximately half of the studies (57%). While majority of studies measured sleep characteristics using self-reported validated questionnaires or simple questions asking sleep characteristics, six studies (17%) used polysomnography to examine sleep architecture.

Quality appraisal

The quality appraisal scores of individual studies included in this review are presented in Table 1 and Additional file 2. Seventeen studies (49%) were assessed as high quality, 14 (40%) as moderate, and 4 (4%) as low quality using the JBI tool. Most studies had clearly identified study participants, reported the setting, and used appropriate measurement. However, 16 studies (46%) identified and dealt with confounding factors.

PMS and sleep health

Table 2 summarized the association between PMS and sleep health dimensions. Twenty-one studies [13, 32, 34–36, 39–43, 46, 48, 50–53, 55–59] explained the association between PMS and sleep disturbances. PMS including premenstrual dysphoria, premenstrual related negative affect symptoms, and PMDD was associated with sleep disturbances in four dimensions of sleep health including Satisfaction, Alertness during waking hours, Efficiency, and Duration (Table 2).

Fifteen studies provided evidence with poor sleep quality (Satisfaction) and PMS. Worse sleep quality (Satisfaction) was associated with women who had PMS compared to those without PMS [34, 36, 39, 50, 51, 53]. Women who had PMS were more likely to report poor sleep quality than those without PMS [32, 43, 58], and having poor sleep quality increased the risk of having PMS [43, 53]. These findings were consistent with women who had premenstrual dysphoria [40] or premenstrual related negative affect symptoms [35], or PMDD [41, 46, 48] with the reporting having worse sleep quality than those without these symptoms. The severity of PMS also had positive association with poor sleep quality [55]. Worse sleep quality was found in those with moderate PMS compared to those with mild PMS or without PMS [13, 57]. As physiological markers, the amount of SWS or delta activity from polysomnography could be measures for good sleep quality (Satisfaction) because of their positive correlation with sleep quality [24]. Two studies found significant decrease of delta activity in women with PMS [39] and premenstrual related negative affect symptoms [35] compared to those without. However, increased SWS activity was found in women with PMDD [41]. While most studies reported that PMS was significantly associated with poor sleep quality, there were no significant differences in SWS or delta activity and the severity of self-reported sleep quality between women with severe PMS and those without PMS [36, 42].

Women with PMS experienced greater daytime sleepiness (Alertness during waking hours) than those without PMS [53]. In addition, women who had PMS tended to have longer times to get back to sleep after frequent awakenings (i.e., increased wake after sleep onset) during sleep, and experienced frequent early morning awakenings (Efficiency) compared to those without PMS [34]. Two studies compared women with moderate levels of PMS, mild levels of PMS, and without PMS [13, 57]. Although women with moderate levels of PMS suffered from greater insomnia (Efficiency) compared to other groups [13, 57], only one study had statistically significant results [57]. In one epidemiology study, women with PMS experienced greater insomnia symptoms (Efficiency) than those without PMS, although there were no differences in the level of daytime sleepiness (Alertness during waking hours), sleep latency, and wake after sleep onset (Efficiency) between women with PMS and without PMS [50]. In women with PMDD, the incidence of insomnia was higher than those without PMDD, and greater severity of PMDD was associated with greater insomnia [52]. In terms of sleep duration, women who had PMDD had significantly shorter sleep duration (Duration) than those without PMDD [46]. Less than 6 h at night was associated with worse PMS [56], but longer sleep duration was not significantly correlated with the severity of PMS symptoms [55]. No studies reported findings about the dimension of timing of sleep in women with PMS.

Dysmenorrhea and sleep health

Nine studies [15, 22, 31, 33, 37, 40, 44, 45, 54] explained the association between dysmenorrhea and sleep disturbances. Among these studies, having dysmenorrhea was associated with worse sleep quality (Satisfaction) [31, 33, 37, 40, 44, 54], excessive daytime sleepiness (Alertness during waking hours) [31], lower sleep efficiency and greater insomnia symptoms (Efficiency) [31, 33, 37, 44], and shorter total hours of sleep (Duration) [22, 33] (Table 2). In three studies, women with dysmenorrhea tended to have worse sleep quality (Satisfaction) than those without dysmenorrhea [31, 37, 40]. Among women with dysmenorrhea, increased severity of dysmenorrhea was associated with worse sleep quality and feeling unrested after waking up (Satisfaction) [33, 44]. Among women of reproductive age, worse sleep quality (Satisfaction) during the coronavirus disease 2019 (COVID-19) pandemic was associated with an increased number of painful periods [54].

Those women who had dysmenorrhea experienced greater daytime sleepiness (Alertness during wakefulness) than those without dysmenorrhea [31]. Women with dysmenorrhea experienced greater insomnia symptoms [31, 44] and insomnia severity (Efficiency) was positively associated with the severity of dysmenorrhea [31, 33, 44]. Conversely, women with dysmenorrhea experienced worse insomnia symptoms than those without dysmenorrhea [33]. In addition, dysmenorrhea was associated with the increase in sleep latency and in time to get back to sleep after waking during sleep (Efficiency) [44], which in turn was associated with a decrease in sleep efficiency (Efficiency) [37, 44]. One study found a significant relationship between women with dysmenorrhea as having shorter sleep duration [33] when compared with those without dysmenorrhea; however, there was no significant relationship between sleep duration and the severity of dysmenorrhea among women with no history of a previous pregnancy and/or childbirth [22]. No studies reported findings about the dimension of timing of sleep in women with dysmenorrhea.

Abnormal menstrual cycle/heavy bleeding and sleep health

Six studies [10, 11, 21, 47, 49, 54] reported relationship between abnormal menstrual cycle and sleep disturbances (Table 2). Among these studies, one study [10] additionally examined the association between heavy bleeding during period and sleep disturbances. Poor sleep quality (Satisfaction) increases the risk of abnormal menstrual cycle change (short, long or missed periods) [10, 54]. One longitudinal study found that having insomnia (Efficiency) increased the risk of menstrual cycle irregularity more than 2 times higher over a year in both women with abnormal menstrual cycle and without this symptom at baseline [11]. Compared to women who had regular sleep duration (more than 8 or 9 h), those with short sleep duration (less than 6 or 5 h; Duration) were more likely to have abnormal menstrual cycle [10, 21, 47, 49] and heavy bleeding during periods [10]. The severity of daytime sleepiness (Alertness during waking hours) and insomnia (Efficiency) were not associated with abnormal menstrual cycle and heavy bleeding during periods [10]. No studies reported findings about the dimension of timing of sleep.

Unspecified studies which explained the association between sleep and menstrual disturbances

Table 2 summarized the results of studies, which were not able to specify the dimension of sleep health or type of menstrual disturbances. About half (57%) of women with PMS had sleep problems and the severity of PMS was associated with greater sleep problems [59]. Similarly, among women with dysmenorrhea, 43% [45] or 63% [15] experienced sleep disturbances as an associated symptom of dysmenorrhea. Women with any type of menstrual disturbances (i.e., PMS and/or bothersome cramping and/or heavy bleeding during periods) were more likely to report frequent insomnia or excessive daytime sleepiness than those without any symptoms during the past 12 months [38]. Regardless of sleep health dimensions, women with PMS had a lower saturation of peripheral oxygen recorded by polysomnography than controls, which indicates the high risk of obstructive sleep disorder [50]. Women with primary dysmenorrhea were more likely to be diagnosed with restless leg syndrome than controls [31].

Discussion

This study provides a systematic review of studies that examine the association between sleep and menstrual disturbances (PMS, dysmenorrhea and/or abnormal menstrual cycle and heavy bleeding during periods). Comprehensively, most of the evidence suggested that having PMS, dysmenorrhea, abnormal menstrual cycle, and heavy bleeding during periods are associated with sleep disturbances following most dimensions of the sleep health framework. Women with menstrual disturbances had poor sleep quality (Satisfaction), had difficulty staying awake or alert during daytime (Alertness during waking hours), had longer sleep latency and waketime after sleep onset, or early morning awakenings, which refers to insomnia symptoms (Efficiency), and had short sleep duration (Duration). In addition, the severity of menstrual disturbances is positively associated with worse sleep quality (Satisfaction), greater daytime sleepiness (Alertness during waking hours) and insomnia symptoms (Efficiency), and/or shorter sleep duration (Duration). However, timing of sleep (e.g., the preference of time for go to sleep and wake up; chronotype) was not examined in women with menstrual disturbances. Overall, there is evidence to suggest that sleep disturbances may be linked to menstrual disturbances in women.

The potential mechanism between sleep and menstrual disturbances is unknown. There is a possibility that sleep disturbances may affect circadian rhythms, which in turn may influence irregular menstrual cycles [60] because sleep and menstruation are both essential rhythmic physiological activities for women [2, 5]. To be specific, sleep disturbances may impair the secretion of gonadal hormones, which results in irregular menstrual cycles. Gonadal hormones in females, such as estrogens and progesterone, are produced by the signal from hypothalamus-pituitary-adrenal axis. The hypothalamus-pituitary-adrenal axis play an important role to control the entire body’s hormonal regulation. A function of hypothalamus-pituitary-adrenal axis is normally controlled by normal sleep circadian rhythms to produce gonadal hormone [61]. However, persons with sleep disturbances usually do not have regular circadian rhythms, which may be associated with irregular synthesis and secretion of female gonadal hormones [62]. A recent study reported that as sleep duration increased, estradiol and luteal phase progesterone concentrations increased [63]. Sleep disorders inhibit gonadotropin-releasing hormone secretion from the pituitary gland, thereby resulting in reduced reproduction of gonadal hormones [64, 65]. Maintaining regular circadian rhythm could be responsible for consistent regulation of menstrual-related hormonal.

The main biological cause of primary dysmenorrhea is the activation of prostaglandins because it induces the muscle and blood vessels to contract around the uterus. In a randomized control trial, the level of prostaglandins was significantly increased following the spontaneous pain intensity among participants under the condition of sleep deprivation [66]. This may suggest that activation of the prostaglandin system in response to sleep disturbances increases dysmenorrhea in women. In addition, the elevated levels of prostaglandin are associated with heavy menstrual bleedings because it is known to inhibit platelet and coagulation factors of aggregation [67]. As a result, women who experience dysmenorrhea and heavy bleeding during their periods may be more likely to have sleep disturbances, which can be mediated by the elevated levels of prostaglandin.

Sleep timing refers to chronotype which indicates the individual’s preference for going to bed and waking up a certain time during a 24-hour period. The evidence regarding the relationship between sleep timing and menstrual disturbances was not found in this review. However, shift workers involuntarily need to be forced to change their sleep timing regardless of their innate circadian rhythm. The shifted sleep-wake cycle is not synchronized with the individualized chronotype [68, 69] and previous studies have shown that rotating shift workers were more likely to experience irregular menstrual cycles or dysmenorrhea [65, 69–72]. However, these previous studies only considered the experience of shift work schedule but did not examine the variability of misalignment between the innate chronotype and the actual sleep-wake cycle in shift workers. It would be further evaluated whether greater variability in sleep timing and the innated chronotype is associated with menstrual disturbances among shift workers.

Despite the close association between sleep disturbances and menstrual disturbances, addressing and treatment of sleep disturbances was not considered as a therapeutic target for menstrual disturbances. The current interventions to reduce menstrual disturbances mainly focus on lifestyle modifications (e.g., dietary modification, exercise, stress reduction, yoga, acupuncture) [73–78]. In a recent randomized controlled trial, as both PMS symptoms and sleep duration were improved by lifestyle modifications in women with irregular menstrual cycle [75]. Given our systematic review, menstrual disturbances in women may be responsive to treatment that are useful for sleep disturbances.

There are several limitations to our study. Most included studies had cross-sectional design except one study [11]; therefore, we cannot assume a causal relationship between sleep and menstrual disturbances. In terms of measures, although there are the diagnostic criteria for PMS, dysmenorrhea, mensural cycle irregularity and heavy bleeding during menstruation, the definition of these menstrual disturbances are varied across the included studies. The studies included in the systematic review measured different aspects of menstrual disturbances and sleep, which varied widely. The heterogeneity among the included studies precluded the conducting of a meta-analysis. Therefore, although only a systematic literature review was conducted in this study, it has the strength of comprehensively examining previous studies on the relationship between menstrual disturbances and sleep, and identifying the research gaps and potential solutions. Most included studies used the self-reported measures to assess sleep. The self-reported measures are practical and cost-effective for research, but objective measures for sleep, such as actigraphy can increase the validity of the study. In addition, there was little and inconsistent evidence whether disturbed polysomnographic sleep measures for sleep quality (i.e., delta wave and SWS) are associated with menstrual disturbances. Therefore, laboratory studies using polysomnography measures needs to be considered to assess the dimension of satisfaction in sleep health framework in the future studies.

Conclusions

This review highlights the effect of sleep disturbances on menstrual disturbances, including PMS, dysmenorrhea, abnormal menstrual cycle and heavy bleeding during periods. According to the Buysse’s sleep health framework, poor sleep satisfaction and efficiency, sleepiness during waking hours, and shorter sleep duration are associated with menstrual disturbances. Since there is currently no research on the relationship between sleep timing and menstrual disturbances, it would be valuable to conduct additional studies to examine whether greater variability in sleep timing and the innate chronotype is associated with menstrual disturbances. The findings from this review suggest that researchers and healthcare providers should consider sleep disturbances as a modifiable factor to manage menstrual disturbances. Moreover, this study provides preliminary evidence to develop sleep-related interventions among women who suffer from menstrual disturbances. Future study should incorporate the five dimensions of sleep health framework to comprehensively understand the multiple levels of sleep disturbances in women who suffer from menstrual disturbances.
