The risks of video games and how to avoid them

Gaming has real risks. They are also frequently exaggerated in ways that make the genuine ones harder to discuss. This page tries to be accurate about both.

What is formally recognised

The World Health Organization includes gaming disorder in ICD-11, its international classification of diseases. The definition is narrow and worth understanding precisely: a pattern of gaming behaviour marked by impaired control over gaming, giving gaming increasing priority over other interests and daily activities, and continuing despite negative consequences — normally evident over at least twelve months, and severe enough to cause significant impairment in personal, family, social, educational or occupational functioning.

Two things follow from that definition. It is a clinical diagnosis for a small minority, not a description of anyone who plays a lot. And the defining feature is harm to the rest of life, not hours played.

If you recognise that pattern in yourself or someone close to you, a doctor is the right person to speak to.

Time displacement

The most common real problem, and it is not about addiction. Gaming expands to fill available time, and displaces sleep, study, exercise and time with people. The harm is in what is not happening rather than in the gaming itself.

What helps: decide when you will stop before you start, keep consoles out of bedrooms for children, and treat sleep as non-negotiable. Late-night play is where this does the most damage.

Physical effects

Eye strain, back and neck pain, and wrist problems from long sessions in a poor position. These are real, common and almost entirely preventable — see our guide to eye strain, posture and comfort.

What helps: a break every hour, a screen at eye level, and a chair that supports your lower back.

Money

Uncontrolled spending on in-game purchases, loot boxes and currency. This is a designed risk — these systems are built to encourage spending — and it affects adults as well as children.

What helps: remove the saved payment card, set spending limits, and use gift cards so the balance is fixed in advance.

Unsuitable content

PEGI ratings exist precisely for this, and they are reliable — assigned by an independent body reviewing the actual content, with icons stating specifically why. See our guide to age ratings.

Note that no rating covers online interaction with other players, which is a separate risk. See our guide to online safety.

Keeping perspective

Most people who play a lot are not experiencing any of this. The risks concentrate where gaming is unstructured, unsupervised for children, and combined with poor sleep.

The practical summary: protect sleep, sit properly, control spending, check ratings, and pay attention if gaming starts displacing things that matter. Those five cover almost everything.
