JAKARTA: From browsing social media to watching videos and chatting with friends, Indonesian university student Tyas Sisianindita spends about eight hours a day on her phone.
A group of fellow students at the University of Indonesia, led by inventor Irfan Budi Satria, has spent three months developing a wearable device that can help internet users like Sisianindita cut down on the time they spend flicking at their phones. Studies have found that prolonged mobile phone usage has a specific lowering effect on HRV levels. The Nettox device emits a sound when HRV and blood oxygen levels fall within this range, which reminds the wearer to stop using their phone.For people aged between 18 and 25, the HRV should ideally stay above 60, according to the American Psychological Association, Satria said.Internet addiction is a growing social issue in Indonesia.
