날씨와 마음 — 더위·미세먼지·비·보름달
「비 오는 날은 아이가 더 예민해요」, 「보름달 뜨면 애들이 들뜬대요」, 「미세먼지 심한 날은 집중을 못 해요」. 날씨에 대한 이런 말은 흔하지만, 연구로 확인된 정도는 저마다 다릅니다. 이 글은 더위처럼 꾸준히 확인된 것, 미세먼지처럼 관련은 보이지만 원인이라 말하기 어려운 것, 보름달처럼 근거가 없는 것을 나눠 정리합니다. 계절(방학·겨울 우울 등)은 이 서재의 「계절이 바뀔 때」 글에서 따로 다룹니다.
01하루하루의 날씨와 기분 — 평균은 작고, 사람마다 다릅니다
2008년 연구진은 1,233명에게 온라인으로 기분을 기록하게 하고 그날의 날씨와 견주었습니다. 기온·바람·햇빛은 기분을 조금 움직였고 햇빛은 피곤함과 관련이 있었지만, 평균적인 효과는 작았습니다. 대신 사람마다 차이가 컸고, 그 차이는 성격·성별·나이로 설명되지 않았습니다.
2011년에는 청소년 497명과 엄마들이 30일 동안 기분을 기록했습니다. 사람들은 날씨에 반응하는 방식에 따라 「여름을 좋아하는 형」, 「영향이 없는 형」, 「여름을 싫어하는 형」, 「비를 싫어하는 형」으로 나뉘었고, 일부 유형은 엄마와 아이가 닮았습니다.
14,478명을 본 2010년 연구에서는 기온·햇빛·강수량이 기분이나 우울과 관련이 없었습니다. 2005년 연구(모두 605명)에서는 따뜻하고 맑은 날 기분과 기억이 좋아졌지만, 봄에만, 그리고 밖에서 시간을 더 보낸 사람에게서만 그랬고, 여름에 더운 날은 오히려 기분이 낮았습니다.
「날씨 때문에 기분이 바뀐다」는 느낌은 누군가에게는 맞고 누군가에게는 맞지 않습니다. 우리 아이가 어떤 날씨에 어떤 모습인지는 며칠 적어 보면 일반론보다 더 정확하게 알 수 있습니다.
