Chinese esports player Jian 'Uzi' Zi-Hao earned more than $500,000 in tournament prize money before announcing his retirement in 2020 after chronic wrist and arm injuries. His case is now part of a broader pattern: as esports has grown into a big business, teams are building sports-medicine staffs to keep players on the screen and out of treatment rooms.
The most common physical injuries in esports fall under eye problems and musculoskeletal issues. Prolonged screen time can cause eye fatigue and a decreased ability to focus, while the light from screens appears to contribute to sleep disturbances by disrupting melatonin release. Players also battle hand and wrist pain from repetitive button-smashing, with injuries such as carpal tunnel syndrome, tendonitis and 'gamer’s thumb' linked to overuse around the thumb and wrist.
Back injuries are another recurring risk. Players can remain seated for three or more hours without a break, and that prolonged sitting can take a toll on the lower back and spine. The sedentary nature of esports has also been linked to deep vein thrombosis, a blood clot that can become life-threatening if it travels to the lungs. In 2011, British gamer Chris Staniforth, who would play for as long as 12 hours at a time, died of the condition.
The mental strain is part of the ledger as well. A 2021 study of Portuguese esports players found that 37% experienced anxiety and depression, and 45% experienced sleep disturbances. Even at the recreational level, players describe the grind of practicing for hours a day, every day, to climb the ladder.
As more injury research has been published, more prevention strategies have followed. Top esports teams now have physical therapists, performance psychologists, athletic trainers and even massage therapists on staff to optimize player performance and recovery. Teams also use group exercise to build rapport and reduce injury risk, while proper spine and limb positioning has become an essential part of competition. Selecting a chair that encourages an upright posture can reduce pain and injury risk, especially when combined with an exercise program focused on functional strength, mobility and stretching.
The numbers come first. Esports may still be marketed as pure digital competition, but the business model now depends on physical durability, medical support and better workplace discipline. When a 'career' can disappear at 25, the market has already voted on the cost of ignoring the body.
Capital rewards clear rules, and esports is writing them in real time: better ergonomics, more recovery, and more accountability for the toll of endless practice. The next competitive edge may not come from another click, but from teams that treat player health as part of free enterprise, not an afterthought.
