Director Gu So-yeon of Dong-an Center Clinic appeared on ‘News Invitation Daily Issue’ and explained holiday syndrome. Holiday syndrome refers to experiencing mental or physical symptoms due to stress during the holidays. She said that it is caused by stress caused by physical fatigue from the long process of returning home, housework, etc., and mental fatigue from gender discrimination, discrimination from in-laws and parents. This started to appear after the traditional family system disappeared and the individualistic culture of the nuclear family became established after industrialization, and its symptoms include physical symptoms such as headaches, dizziness, stomach problems, and indigestion, and mental symptoms such as fatigue, depression, and breathing difficulties. Most of those who suffered from holiday syndrome were housewives, but he emphasized that the scope has recently expanded to include husbands, the unemployed, single people, and mothers-in-law, and it is emerging as a social problem.
