0 After two hours of Roblox curled over his tablet like a prawn, Kai stood up and said «ow, my neck» in the voice of his grandad. 1 His mum laughed, then showed him how to sit back with the screen held up near eye level, so his head was not hanging forward. 2 Ollie liked to play lying on his tummy on the floor; it was comfy for twenty minutes and his back ached the whole next day. 3 How you sit matters as much as how long you sit. 5 Priya's eyes went blurry after a long game, because people blink less when they stare at a screen and eyes get tired from looking at something close for a long time. 6 Her dad taught her the 20-20-20 rule: every twenty minutes, look at something about twenty feet away (about six metres, like the far side of a big room) for twenty seconds. 7 Theo thought playing in the pitch dark was cooler, like a cinema. 8 He got headaches, and when he switched on a lamp they went away, because a bright screen in a dark room is hard on the eyes. 9 Ruby forgot to drink anything for three hours of Minecraft and ended up tired, thirsty and headachey; now a water bottle lives next to her console. 10 Zara's optician asked her how long she plays. 11 Zara went red and felt a bit nervous, but her eyes were fine; the optician just said to keep taking breaks and come back for regular checks. 12 Jayden started doing star jumps between Fortnite matches. 13 His squad laughed at first, then saw him on camera bouncing about and joined in; now the whole squad does «jump breaks», including his cousin in Australia. 14 Noah's dad got him a proper chair, and his back stopped aching. 15 And Mia's rule is simple: after an hour of games she goes outside and kicks a football about, then comes back with fresh energy. 16 A body needs running about every day as much as a brain likes games. 17 Sitting hunched with your head bent forward over a screen strains the neck and back. 18 Holding a screen nearer eye level and sitting back supported is easier on the neck. 19 Staying in one position for a long time, sitting or lying, makes muscles stiff and achy. 20 Sore thumbs or hands after playing are a sign to take a break, not a badge of skill. 21 People blink less when staring at screens, which can make eyes feel dry and tired. 22 The 20-20-20 rule: every 20 minutes, look at something about 20 feet away for 20 seconds. 23 Playing with a bright screen in a dark room can cause eye strain and headaches, so a light on helps. 24 Forgetting to drink during long games can leave you tired and headachey. 25 Short movement breaks between games, like star jumps or a walk, keep the body fresh. 26 Regular eye checks with an optician can catch problems early. 27 Children need about an hour of active play every day. 28 If pain does not go away after resting, tell a grown-up, who may take you to a doctor. ← previous Homework first?next → Screen-time rules and arguments↑ back to Everyday This page in Markdown → https://md.mova.elamur.ai/free/en/corpora/school/everyday/420-eyes-backs-and-thumbs/
