Please provide ​official statistics relating to insomnia and the cost to NHS of insomnia, please?
We said
Thank you for your request.
Unfortunately, we do not hold statistics on insomnia, nor do we hold statistics on costs to the NHS at the granular level requested. NHS Digital may be better placed to assist with your request, as they conduct a mental health survey and may have data from medical records. They can be contacted via email at enquiries@nhsdigital.nhs.uk.
