00:02Sleep improvement mobile phone apps may help some people but could also increase stress for those
00:06with insomnia, new research suggests. Experts say apps tracking sleep often rely on sensors in
00:12smartwatches and fitness bands and may not always give accurate results. A study of 1,002 people
00:18with the average age of 50 found that around 48% learned more about their sleep while 17%
00:25worried more. Younger adults reported stronger effects, both positive and negative. People with
00:32insomnia were more prone to negative thoughts about sleep. Researchers advise using apps carefully,
00:38limiting screen time before bed, and going to sleep when genuinely tired.
