The present research explored how mothers’ own childhood experiences are linked to their perceptions of their children's sleep regulation. It focused on collective sleeping; a practice used in the past in the Israeli kibbutz, and used a quasi-experimental research design to examine whether mothers who were raised in collective sleeping arrangements differed from mothers who were raised in home sleeping. Two typically developing cohorts: infants (n = 68; ages 9–15 months; M = 12.2, SD = 2.2) and preschool children (n = 113; ages 48–55 months; M = 51.5, SD = 1.85) participated in this investigation. Sleep regulation and temperament were reported for infants and children, whereas for mothers data were collected on separation anxiety and appraisal of the ecology in which they were raised. Collectively raised mothers evaluated their upbringing significantly more negatively than home-raised mothers, expressed higher separation anxiety with regard to an alternative caregiver, but were not different in their views of their child's sleep difficulties. For infants, it was maternal separation anxiety that contributed uniquely to the explained variance in maternal view of sleep regulation difficulties. For preschool children, it was maternal evaluation of own childhood ecology and child's temperament that contributed uniquely to the explained variance in maternal view of sleep regulation difficulties. These findings suggest that mothers’ representations of their sleep-related early experiences, rather than their childhood ecology in and of itself, influenced their perceptions about their child's sleep, which, in turn, affect child's sleep patterns. Implications to caregiving are discussed. 相似文献

目的:探讨重复经颅磁刺激(rTMS)改善睡眠的效果,为使用rTMS提高运动员的睡眠质量提供理论基础。方法:采用被试内设计,在被试脑干的中缝核区域分别施加假刺激(S)、无刺激(N)和磁刺激(T),比较刺激后主观感觉、生理及行为的变化。结果:在被试脑干的中缝核区域施加1 Hz,80%RMT,1 500次rTMS(持续10 s间隔2 s)后,被试的自评睡眠质量提高,状态焦虑降低;呼吸曲线的波动减少、呼吸频率降低,脉率降低,心率变异性(HRV)的相邻NN间期差值的均方根(RMSSD)和相邻NN间期差值的标准差(SDSD)降低;肢体活动减少。结论:rTMS能够提高睡眠质量,rTMS刺激后呼吸、脉率以及心率变异性(HRV)的变化在一定程度上可以对其生理效果进行解释。 相似文献

采取问卷调查的方法,对中学生课业负担、睡眠状况、饮食行为和体育锻炼情况进行调查。结果发现：80.9%的中学生每天的学习时间超过国家规定标准,60.7%的中学生睡眠时间不足,50.7%的中学生早餐不规律、超过三成的中学生有偏食和零食习惯,79.7%的中学生每天体育锻炼时间不达标,仅有16.2%的中学生养成体育锻炼的习惯。结果表明：中学生课业负担重,导致熬夜、睡眠不足现象比较严重,同时中学生不良饮食行为问题突出,特别是运动不足问题令人堪忧。 相似文献

本文探讨大学生沉思在孤独与抑郁情绪和睡眠质量之间的中介作用。采用UCLA孤独量表、沉思反应量表(RRS)、流调中心用抑郁量表(CES-D)和匹茨堡睡眠质量指数量表(PSQI)对700名大学生进行施测。根据测量结果,认为沉思在孤独与抑郁情绪和睡眠质量之间起到部分中介作用,沉思是孤独与消极健康状况的重要影响机制。 相似文献

褪黑素是存在于从藻类到人体等多种生物体中的一种激素类化合物,因能使产生黑色素的细胞颜色变浅而得名.国内外对褪黑素的生物学作用开展了广泛的研究,表明其具有调节睡眠、抗衰老、调节免疫、抗肿瘤等多项生理功能.本文主要介绍了褪黑素的生物合成和代谢途径,以及近年来有关褪黑素生物学作用的研究,并对褪黑素的开发前景进行了讨论. 相似文献

目的:探究青少年在急性部分睡眠剥夺状态下进行高强度运动前后静息态脑电(EEG,electroencephalography)微状态的变化特征。方法:选取20名健康男性青少年(18~22岁)为实验对象,前后两次随机在正常睡眠(Control)和单次部分睡眠剥夺(Sleep Deprivation,SD)的状态下,于次日上午参与跑台的布鲁斯(Bruce)运动方案;对其运动前后6min的静息态EEG信号进行采集,基于Matlab软件对数据进行微状态分析,选取持续时间、时间覆盖率、发生频率、转换概率作为分析指标。结果:与Control相比较,受试者SD状态下的微状态C的持续时间和时间覆盖率显著增加(P<0.05),微状态D的发生频率显著减少(P<0.05),微状态A和B更倾向于向C转换(P<0.05);而SD后进行大强度运动导致受试者微状态C的持续时间和时间覆盖率极显著增加(P<0.001),微状态D的持续时间和发生频率显著减少(P<0.05),微状态A、B更倾向于向C转换,而微状态C更倾向于向B和D转换(P<0.05 & P<0.01)。结论:睡眠缺失会破坏静息态网络之间的动态平衡,这种失衡在睡眠不足状态下进行运动后会更加严重高强度。 相似文献

采用实验测评的方法对城市老年失眠症患者进行运动干预,为期三个月的研究发现:药物疗法配合运动干预比单纯的药物治疗效果更好;实验一组和实验二组睡眠结构在NREM浅睡期、NREM深睡期、REM睡眠期、醒觉总时间等四个维度上有非常显著性差异,在入睡潜伏期、睡眠总时间和醒觉次数上没有明显差异,提示实验一组被试睡得更"沉"、更"香",具有更高的睡眠质量,这表明对于失眠症患者来说,有氧运动辅以抗阻训练的综合锻炼方式比单纯的有氧运动效果更好。 相似文献

ABSTRACTThe aim of this study was to evaluate the effects of sleep hygiene (SH) education on sleep quality in soccer players after a late-evening small-sided-game (SSG) training session. Twenty-nine non-professional players were recruited and allocated to either an experimental group (EG, n = 17) that received SH education, or a control group (CG, n = 12). SSG consisted of 3 × 4 min in a 4vs4, with 3 min of recovery and was performed at 8.00 p.m. Sleep quality was monitored via actigraphy and sleep diary entries before (PRE) and two nights after (POST1, POST2) the SSG. Sleep latency (SL) differed between the two groups at POST1 (4.9 ± 5.4 vs. 15.5 ± 16.1 for EG and CG, respectively; p = 0.017, effect size [ES] = 2.0); SL values were lower at POST1 compared to PRE for the EG (?47%; p = 0.021, ES = 0.6). Subjective sleep quality was better in the EG than the CG at POST1 (8.6 ± 1.0 vs. 7.1 ± 2.0 for EG and CG, respectively; p = 0.016, ES = 0.9) with a significant improvement over PRE-values (+11.0%, p = 0.004, ES = 0.8). Although SL and subjective sleep quality did not decrease significantly from POST1 to POST2 values at POST2 no longer differed significantly form baseline and, hence, indicate that observed effects may be short-lasting. No other objective sleep indices were influenced by late-evening training or SH practices implemented by the EG. Soccer players may benefit from acute SH strategies to reduce the time to sleep onset after late-evening training sessions. 相似文献

Since the invention of artificial light, people have been working, studying, and playing for longer hours than ever before. They are also sleeping less as a result. This article examines the impact of sleep deprivation on people generally, and specifically on college students. Students accrue a large sleep debt that impairs their ability to function adequately. Students suffering from sleep deprivation can be as impaired as if they are drunk. They suffer damage to their minds and bodies. Adequate sleep can repair this damage, but with the many demands on college students, they may be unlikely to be able to accomplish this. Studies have indicated that naps are beneficial in helping to reduce students' sleep debts. Universities are realizing the importance of naps, and university libraries may be ideal locations for napping stations. Several options of providing students with safe comfortable napping areas are discussed. 相似文献
