Emotions involve physiological arousal, expressive behaviors and conscious experience.

情绪包括生理唤醒、表达行为和意识体验。

Anti-anxiety medications can help decrease the heightened physiological arousal often seen in people with PTSD, and finally sleep-aids can also be an helpful because lack of sleep and restlessness is such a serious problem in PTSD.

抗焦虑药物能降低PTSD患者常见的高觉醒度；最后，安眠药也有所帮助，因为缺乏睡眠和躁动是创伤后应激障碍的严重问题。
