E-sports champions, who compete in video game tournaments, face a variety of physical injuries similar to those experienced by athletes in traditional sports. These injuries include eye strain, repetitive motion injuries, back problems, and even blood clots. The causes often stem from long hours of screen time, repeated hand and wrist movements, and extended sitting. For example, Jian "Uzi" Zi-hao, a top player in League of Legends, retired in 2020 due to chronic wrist and arm injuries. Despite his retirement, he made a brief return to play in 2022 and 2023. The intense pressure to improve rankings in e-sports often leads to long training sessions, sometimes several hours a day. A 2021 study of Portuguese e-sports players found that nearly 40% experienced anxiety and depression, and almost half had sleep disorders. Prolonged screen exposure can cause eye fatigue and reduced concentration. Additionally, the blue light from screens can disrupt the production of melatonin, a hormone that helps regulate sleep, contributing to sleep issues. Many e-sports players suffer from hand and wrist pain, including conditions like carpal tunnel syndrome, tendinitis, and "gamer's thumb." These injuries are similar to those seen in workers who perform repetitive tasks, such as in factories. Sitting for long periods can lead to back and spine problems, and the sedentary lifestyle associated with e-sports has been linked to deep vein thrombosis (DVT), a serious condition where blood clots form in the legs. In 2011, British e-sports player Chris Staniforth died from DVT after playing for up to 12 hours straight without a break. To address these issues, top e-sports teams are increasingly using preventive measures and treatment strategies. Many employ physiotherapists, performance psychologists, physical trainers, and massage therapists. Ergonomic practices, such as using chairs that encourage proper posture, are also being incorporated into training routines. Some players, like Lee "Faker" Sang-hyeok, a renowned League of Legends player, have returned to competition after injuries through treatment programs that include posture adjustments and physiotherapy. Researchers suggest that e-sports players should be viewed more like musicians and dancers than traditional athletes, due to the physical and mental demands of the field. For example, studies have found similar patterns of forearm muscle fatigue in e-sports players and pianists. However, no direct comparison between these groups has been made yet, highlighting the need for further research into the unique health challenges faced by e-sports competitors.
