Health & safety

Photosensitive seizures

Anyone who has ever had symptoms linked to a photosensitive epileptic condition should consult a doctor before playing. Parents should watch for these symptoms in their children, who are more likely than adults to experience them.

Symptoms may include:

• light-headedness, altered vision or eye or face twitching;
• jerking or shaking of the arms or legs;
• disorientation, confusion or loss of awareness of your surroundings;
• convulsions or loss of consciousness.

Stop playing immediately and consult a doctor if you experience any of these symptoms.

To reduce the risk of a photosensitive seizure:

• sit further from the screen;
• use a smaller screen;
• play in a well-lit room;
• do not play when you are drowsy or tired.

Eye strain and motion discomfort

Playing for a long stretch can tire your eyes, and some people feel nausea, dizziness or motion sickness from on-screen movement. Take a break of at least 10 to 15 minutes every hour, and stop playing if you feel unwell. Carrying on rarely makes it better.

Repetitive strain

Extended sessions of keyboard and mouse play can cause aching or stiffness in your hands, wrists, arms, neck, shoulders or back. Rest, stretch, and keep a comfortable posture. If pain, numbness, tingling or burning persists after you stop playing, see a doctor.

Hearing

Extended listening at high volume, particularly through headphones, can damage your hearing permanently. Set the volume at a level where you can still hear someone speaking in the room, and adjust it in Settings → Audio.

General

Do not play when you are tired, short on sleep, or under the influence of alcohol or drugs. Keep sessions in proportion to the rest of your day. If you have a medical condition or are pregnant, or if you have an implanted medical device, consult a doctor before playing.
