超50万人的研究显示:晒太阳可以改善失眠和抑郁症状

2021-10-14 K.K MedSci原创

白天缺乏光照是抑郁症状、情绪不佳和失眠的一个风险因素。

近期,由澳大利亚莫纳什大学发表在《Journal of Affective Disorders》的一项新研究显示,每天足够的阳光可以影响一个人的情绪和睡眠质量。

 

Angus C. Burns et al, Time spent in outdoor light is associated with mood, sleep, and circadian rhythm-related outcomes: A cross-sectional and longitudinal study in over 400,000 UK Biobank participants, Journal of Affective Disorders (2021). DOI: 10.1016/j.jad.2021.08.056

研究人员对英国生物银行项目中50多万名参与者(n= 502000;37~73 岁;54%为女性)进行的横断面和纵向研究发现,白天缺乏光照是抑郁症状、情绪不佳和失眠的一个风险因素。

这项研究的参与者说,他们每天在户外花费的时间中位数为2.5个白天。白天每增加一个小时的户外活动,就会降低终身重度抑郁症的几率(95% CI OR:0.92-0.98)、抗抑郁药的使用(OR:0.92-0.98)、较少的失落(OR:0.93-0.96)和情绪低落(OR:0.87-0.90)、更大的快乐(OR:1.41-1.48)和较低的神经质症(发生率比,IRR:0.95-0.96)。

此外,白天每小时的光照与更容易起床(OR:1.46-1.49)、较少的疲劳(OR:0.80-0.82)、较少的失眠症状(OR:0.94-0.97)有关。

莫纳什大学特纳大脑和心理健康研究所博士生Angus Burns说:"在这项研究中,我们观察到,白天在户外光线下呆的时间越长,与抑郁症状越少,使用抗抑郁药物的几率越低,睡眠越好,失眠的症状越少。这其中的原因可能是光对人体的昼夜节律系统、大脑情绪的直接影响。”

副教授Sean Cain 说,日常生活进行这些细微的调整可以帮助自己改善情绪、睡眠和能量。人们现在人工照明条件下度过大部分清醒的时间,阳光照射减少,夜间光线照射明亮。通过在户外光线下活动可能改善更好的情绪、睡眠质量和早起。

因此,人们白天光照不足可能是导致抑郁症患者情绪和睡眠结果不佳的一个关键原因。当太阳出来的时候,尽可能多地接受光照,但太阳落山后,接受黑暗。你的身体会变得更好。
