Spring Suicide Surge Pushes Korea's Depression Cases Past One Million

TL;DR In 2022, 3,488 suicides occurred between March and May, with April alone accounting for 1,198 deaths, while depression patients rose from 590,000 in 2013 to about 1 million in 2022.

Context Spring traditionally brings longer days and warmer weather, yet suicide rates in Korea climb 20‑30% above winter levels. A 2020 cohort study of national suicide records (n=12,906 deaths in 2022) found that 27% of yearly suicides happened in the March‑May window, peaking in April. Researchers attribute the rise to shifting sunlight, fine‑dust exposure, and social transitions such as new school semesters and job transfers, which can disrupt circadian rhythms and heighten anxiety.

Key Facts Seo Kyung‑je, a 34‑year‑old office worker, described his spring experience: "The weather is sunny, but I feel anxious, as if I'm the only one standing still. It's agonizing." He reported losing three kilograms in a month due to insomnia and appetite loss. The National Health Insurance Service reported depression patients increasing from roughly 590,000 in 2013 to nearly 1 million in 2022, almost a doubling. Seasonal Affective Disorder accounts for about 11% of all depression cases and often presents as agitated depression in spring, marked by restlessness, irritability, and weight loss.

What It Means The data show a correlation between spring environmental changes and heightened suicide risk, but they do not prove causation; underlying vulnerabilities such as existing mood disorders amplify the effect. For individuals, maintaining a regular sleep schedule, seeking cognitive‑behavioral therapy for persistent insomnia, and monitoring mood shifts during seasonal transitions are practical steps. Policymakers should consider expanding accessible mental‑health screening in schools and workplaces before the spring peak.

What to watch next Upcoming analyses of 2023 suicide and depression trends will reveal whether recent public‑health campaigns have altered the seasonal pattern.
