BACKGROUND
Bright artificial light improves non-seasonal depression. Preliminary observations suggest that sunlight could share this effect.
METHODS
Length of hospitalization was recorded for a sample of 415 unipolar and 187 bipolar depressed inpatients, assigned to rooms with eastern (E) or western (W) windows.
RESULTS
Bipolar inpatients in E rooms (exposed to direct sunlight in the morning) had a mean 3.67-day shorter hospital stay than patients in W rooms. No effect was found in unipolar inpatients.
CONCLUSIONS
Natural sunlight can be an underestimated and uncontrolled light therapy for bipolar depression.
LIMITATIONS
This is a naturalistic retrospective observation, which needs to be confirmed by prospective studies.
背景
明亮的人工光可改善非季节性抑郁症。初步观察表明，阳光可能也有此作用。
方法
记录了415名单相抑郁症住院患者和187名双相抑郁症住院患者的住院时间，这些患者被分配到朝东（E）或朝西（W）窗户的病房。
结果
住在E病房（早晨接受阳光直射）的双相抑郁症住院患者的平均住院时间比住在W病房的患者短3.67天。在单相抑郁症住院患者中未发现此效应。
结论
自然阳光可能是一种未被充分认识且未得到控制的双相抑郁症光疗法。
局限性
这是一项自然主义的回顾性观察研究，需要前瞻性研究予以证实。
