Background: The effect of nighttime aromatherapy on sleep has been explored. However, its effect on mood states has not been established. This study aimed to determine the effects of nighttime aromatherapy, using skin patches with lavender aroma, on mood states of young women. Methods: Twenty-four young women slept as usual with a skin patch placed under their clothing for seven consecutive nights. One group of subjects (AROM group) used skin patches with lavender aroma, whereas the other group (CONT group) used skin patches without the aroma. The primary outcome measure was mood states assessed with the Profile of Mood States 2nd Edition (POMS 2). The secondary outcome measures were physiological indices of stress assessed by salivary α-amylase activity, cortisol concentration, and pulse rate measured immediately after waking up. Assessments were performed pre-intervention, the morning after the first intervention night, and post-intervention.Results: Skin patches with lavender aroma improved total mood disturbance and two negative subscales scores of the POMS 2 in the AROM group over time. There was an interaction between time and treatment condition (with/without aromatherapy) for the fatigue-inertia subscale, although no interaction was detected between time and condition for total mood disturbance and the anger-hostility subscale. The positive subscales scores of POMS 2 did not change in both groups. In the AROM group, salivary α-amylase level measured the morning after the first intervention night was significantly higher than the pre-intervention level; however, there was no significant difference between pre- and post-intervention. Moreover, there were no significant changes in salivary cortisol concentration and pulse rate in both groups. Conclusions: Unlike the AROM group, no improvement in mood states was observed in the CONT group. Low-cost and easily applicable aromatherapy using skin patches are potentially useful in stabilizing mood states in various populations.Trial registration: UMIN-CTR, UMIN000035051.

“…An evening chronotype in children of pre-scholar and scholar age revealed a higher association with several sleep disorders, but no specific association with parasomnia [77,78]. Conversely, an association between a delayed sleep-wake phase and the occurrence of NREM parasomnias was found among Japanese students [79].…”

Disorders of Arousal: A Chronobiological Perspective

Non-rapid eye movement (NREM) sleep parasomnias are characterized by motor and emotional behaviors emerging from incomplete arousals from NREM sleep and they are currently referred to as disorders of arousal (DoA). Three main clinical entities are recognized, namely confusional arousal, sleep terror and sleepwalking. DoA are largely present in pediatric populations, an age in which they are considered as transitory, unhabitual physiological events. The literature background in the last twenty years has extensively shown that DoA can persist in adulthood in predisposed individuals or even appear de novo in some cases. Even though some episodes may arise from stage 2 of sleep, most DoA occur during slow wave sleep (SWS), and particularly during the first two sleep cycles. The reasons for this timing are linked to the intrinsic structure of SWS and with the possible influence on this sleep phase of predisposing, priming and precipitating factors for DoA episodes. The objective of this paper is to review the intrinsic sleep-related features and chronobiological aspects affecting SWS, responsible for the occurrence of the majority of DoA episodes during the first part of the night.

“…We further investigated the influence of the changes in sleep–wake schedules on individual lifestyles and negative emotions, and found that the delayed sleep–wake times could positively predict the participants' negative emotions and electronic device use, but negatively predict the exercise levels during the stay‐at‐home orders. Previous literature had proved that sleep loss and late nocturnal sleep are related to deterioration in physical health, mental health and quality of life (Haraden et al., 2017; Kayaba et al., 2020; Krističević et al., 2018; Morita et al., 2015). Delayed sleep–wake patterns can negatively predict positive emotions and social experiences (Asaoka et al., 2004; Segura‐Jiménez et al., 2015; Totterdell et al., 1994).…”

This study aimed to assess changes in sleep pattern and their influence on people's daily life and emotion during the COVID‐19 pandemic. Self‐developed questionnaires were used to measure changes in nocturnal sleep, daytime napping, lifestyles and negative emotions in individuals before and after the COVID‐19 pandemic. Nine hundred and thirty effective questionnaires were collected in this study. Repeated measures analysis of variance and hierarchical regression analysis were applied. We found that individuals' sleep rhythms were delayed, and sleep duration and sleep latency were increased during the stay‐at‐home orders. Meanwhile, their exercise levels and learning/working efficiency were decreased, and electronic device use time, annoyance levels and anxiety levels were increased. Delayed sleep patterns affected lifestyles and emotions. Moreover, sleep quality positively predicted learning/working efficiency and exercise levels, and negatively predicted use of electronic devices and negative emotions. Sleep patterns became delayed on weekdays during stay‐at‐home orders in all four daytime napping groups (no daytime napping, daytime napping as before, more daytime napping and less daytime napping), and the group taking daytime naps as before had a minimal variation, and their lifestyles and emotions were significantly better than those of the other groups. This study demonstrated that under the influence of stress caused by the pandemic, maintaining regular daytime napping was an effective way to stabilize sleep patterns and biological rhythms, keep good lifestyles and alleviate the effect of acute psychological stress, and to prevent and control mental disorders during the pandemic.
