スマホ脳
의미: Smartphone brain — cognitive and psychological effects from excessive phone use, popularised by the Swedish book that became a bestseller in Japan.
スマホ脳 (literally 'smartphone brain') entered mainstream Japanese vocabulary following the massive success of Swedish psychiatrist Anders Hansen's book 「スマホ脳」, published in Japanese in 2021. The book argued that smartphones are re-wiring our brains in harmful ways — reducing attention spans, increasing anxiety, and disrupting sleep. It sold over 1.5 million copies in Japan alone, making スマホ脳 a household concept. The term is now used both to refer to the book's central thesis and more loosely to describe anyone who seems addicted to or cognitively impaired by their phone.

✓ 올바른 표현
- スマホ脳って本当にあるんだって、集中力がどんどん落ちるらしい。 (Smartphone brain is apparently real — it says your concentration keeps declining.)手机脑好像真的存在，据说注意力会持续下降。Parece que el cerebro de smartphone es real: dicen que la concentración va disminuyendo cada vez más.스마호노가 진짜 있대, 집중력이 점점 떨어진다고 해.

✗ 잘못된 표현
- 「スマホ依存」と「スマホ脳」を完全に同じ意味で使う (Using スマホ依存 and スマホ脳 interchangeably — スマホ依存 means addiction/dependency, while スマホ脳 refers specifically to the neurological and cognitive effects described in Hansen's framework)把「スマホ依存」和「スマホ脳」完全当作同义词使用——スマホ依存指的是成瘾/依赖，而スマホ脳特指汉森理论框架中描述的神经和认知层面的影响Usar スマホ依存 y スマホ脳 como sinónimos exactos: スマホ依存 significa adicción o dependencia, mientras que スマホ脳 se refiere específicamente a los efectos neurológicos y cognitivos descritos en el marco de Hansen.「スマホ依存」과 「スマホ脳」를 완전히 같은 의미로 사용하기 (スマホ依存은 중독·의존을 의미하고, スマホ脳는 한센의 이론에서 설명하는 신경학적·인지적 영향을 구체적으로 가리킨다)
흔한 실수
- Assuming スマホ脳 is an established medical diagnosis — it is a popular science concept, not a clinical term
- Pronouncing 脳 as のう with a falling tone — it should be の↑う↓ in standard Tokyo pitch accent
기원과 역사
Directly derived from the Japanese title of Anders Hansen's 2020 Swedish book 'Skärmhjärnan,' translated as「スマホ脳」by Shinchosha in 2021. スマホ (smartphone) + 脳 (brain). The book's extraordinary success in Japan — driven partly by TV appearances and social media discussion — made the compound term enter everyday usage beyond the book itself.
