A survey of over 500 South Korean professional footballers reveals widespread health issues, including dizziness and fainting, caused by extreme heat.
A recent survey of professional footballers in South Korea has brought to light a significant crisis regarding athlete welfare during the summer months. Conducted among 536 players across the K League and the WK League, the data reveals that an overwhelming 86.2% of respondents have experienced severe physical strain directly attributed to extreme temperatures. As South Korea faces increasingly intense summer heatwaves, with pitch-level temperatures regularly exceeding 40 degrees Celsius (104 degrees Fahrenheit), the physical toll on athletes has reached a breaking point.
The findings are particularly concerning for the long-term health of the league's participants. Nearly two-thirds of the surveyed athletes reported experiencing dizziness during competitive matches or rigorous training sessions. Furthermore, 56.6% of participants admitted to suffering from severe dehydration, while an alarming 13% reported suffering from temporary lapses in consciousness. These figures have prompted the Korea Professional Footballers Association (KPFA) to sound the alarm, labeling the current environmental conditions as a major threat to the integrity of the sport and the safety of its workers.
KPFA President Lee Keun-ho, a veteran former national team player, emphasized that the reported incidents are not merely inconveniences but represent a critical failure in current safety standards. He noted that the frequency of these health episodes serves as a glaring warning sign that the existing measures are insufficient to protect players from the physiological dangers of heat exhaustion and heatstroke.
The current system for managing heat stress, which typically mandates a cooling break of approximately three minutes when temperatures hit specific thresholds, has come under heavy scrutiny. Nearly half of the athletes surveyed expressed significant dissatisfaction with this policy, arguing that it fails to mitigate the cumulative impact of playing for ninety minutes in stifling conditions. The athletes contend that these brief pauses are insufficient for the body to recover from the heat accumulation experienced on the pitch.
Beyond the duration of the breaks, the nature of the facilities in use has become a focal point of the debate. Many players, particularly those in the women’s league, are frequently forced to compete on artificial turf surfaces. These materials are known to absorb and radiate heat, creating an environment that can be significantly hotter than the ambient air temperature. The lack of air-conditioned changing facilities at many venues further exacerbates the inability for players to cool down effectively before, during, or after their matches.
There is a growing consensus among the players that the governing bodies—the Korea Football Association (KFA), the K League, and the WK League—must move away from rigid scheduling. Nearly 90% of those surveyed support comprehensive changes to match operations. Many are calling for later kickoff times to avoid the peak intensity of the midday sun, while others are advocating for the outright postponement or cancellation of matches whenever official heat advisories are in effect.
The push for reform extends beyond minor schedule adjustments. Many players and union representatives are calling for a fundamental shift in how the South Korean football season is structured. There is a strong movement in favor of transitioning to an autumn-spring schedule, similar to many European leagues, which would largely remove the necessity of playing high-intensity matches during the most dangerous weeks of the summer.
KPFA Women’s President Ji So-yun highlighted the disparity between how different sports handle extreme weather. She pointed out that professional baseball in South Korea has already adopted a proactive stance, frequently cancelling games when temperatures pose a risk to athletes. The union argues that football should follow this lead, moving away from a rigid calendar that prioritizes commercial scheduling over the basic health and safety of the players who drive the sport.
In response to these findings, the KFA has issued a statement acknowledging the gravity of the concerns. The governing body affirmed that player welfare is their top priority and noted that they are actively exploring ways to optimize match scheduling and cooling procedures. However, the KFA also highlighted the logistical difficulties they face, including stadium availability and the complexities of managing a professional league calendar. The union remains steadfast in its position, insisting that these logistical hurdles cannot be used as an excuse to ignore the clear medical evidence that current conditions are hazardous to the health of the players.
