Heart's heat stroke is the condition where you are prone to heat stroke in summertime – not physically, but psychologically, in the form of short temper and difficulty in staying calm. High-risk groups include white-collar workers under pressure and people who are poor at communicating.

“心理中暑”指的就是你在夏天容易脾气暴躁、难以平静的心理状态。每天有极端工作压力的白领和不善交流的人都是心理中暑的高发团体。

Medical research shows that people's mood, mental state and behavior have something to do with the change of seasons. In hot summer, approximately 10% of people would appear abnormal in their mood and behavior, which is heart's heat stroke.
