The wonderful gift of sleep probably goes for granted by those who possess it in abundance. It has been estimated up to 20% of the UK’s adult population doesn’t get enough sleep – typically between seven and nine hours each night. This is more than the combined populations of Bangor, Caernarfon, Rhyl, Prestatyn, Connah’s Quay and Llandudno, not sleeping for long enough on a regular basis.
