节后综合症的英文：
post-holiday syndrome

节后综合症就是人们在大假之后的各种生理表现。比如，在节后的两三天里感觉厌倦，提不起精神，上班的工作效率低，甚至有不明原因的恶心、眩晕、肠道反应、神经性厌食、焦虑、神经衰弱等；老人难以适应突然恢复的清静日子；孩子无法安心为即将开始的学习做准备。

英英解释：

The syndrome you have when you have gone through a holiday and no longer have a functional daily rhythm. A person with a Post Holiday Syndrome will then be awake at night and sleep at day. It may be in relation to the heavy partying a lot of people do when on holidays.
