Hundreds of children are being treated for sleep problems in Wales every year. In some cases, babies, infants and teenagers have been admitted to hospital while in north Wales alone, the number being prescribed medication rose by 20% in the last three years. Cases have included severe neuro-disabilities and epilepsy, but experts said many also suffered from insomnia, sleep walking and chronic nightmares. Campaigners said sleep-deprivation could have “severe consequences”. The Children’s Sleep Charity said many families were now at “crisis point” due to a lack of sleep, with technology use before bedtime being a major factor. Public Health Wales (PHW) said sleep was as important to a child’s health and wellbeing as healthy eating and exercise, and children with poor sleep patterns were more likely to be obese. Figures obtained under the Freedom of Information Act by BBC Wales found at least 408 children have been admitted to hospitals across Wales suffering from sleep disorders since March 2013. However, the number is expected to be much higher as two health boards, Cardiff and Vale along with Powys, did not provide information. Children aged between 0 and four-years-old made up the highest number of inpatients, with some newborns being treated for sleep-related issues from the day of birth.
