Physical consequences of gaming addiction include carpal tunnel, migraines, sleep disturbances, backaches, eating irregularities, and poor personal hygiene.

Carpal Tunnel Syndrome

Carpal tunnel syndrome is caused when the main nerve between the forearm and hand is squeezed or pressed. This occurs when the carpal tunnel – the area of the wrist that houses the main nerve and tendons – becomes irritated or swollen. Overuse of a computer mouse can cause such irritation and swelling, as can excessive use of a video game controller.

Migraines

Migraine headaches typically start in one spot and slowly spread, getting more painful as they progress. In most cases, the pain can be so extreme that it causes the person to vomit. Light and noise can also cause excruciating pain. Someone who plays video games for a long period of time is more prone to migraines because of the intense concentration required and the strain put on the eyes.

Sleep Disturbances
Sleep-related disorders, including insomnia, narcolepsy, sleep apnea, nocturnal myoclonus (periodic leg or arms jerks during sleep), and parasomnia (i.e., night terrors, sleepwalking or talking, and nightmares). Sleep disturbances are caused, in part, by overstimulation of the brain. However, some people can’t get a good night’s sleep simply because they think obsessively about the game they’re playing.

Backaches
Backaches are a common physical symptom of gaming addiction because most gamers stay seated in the same position for hours on end. The lack of movement causes stiffness and soreness, but could deteriorate into chronic back problems.

Eating Irregularities
Eating irregularities are caused by gaming addiction simply because most addicted gamers don’t want to take the time to eat properly. Rather than eating healthy, balanced meals, they eat food that is quick and usually unhealthy. In extreme cases, the gamer may choose not to eat at all.

Poor Personal Hygiene
An addicted gamer is not going to take the time to properly care for himself. Showers, face-washing, and brushing hair and teeth all get put on the back burner. It simply becomes less of a priority, if it’s a priority at all.
