About Viphnorenrax
A London-based practice dedicated to evidence-based sleep hygiene consultancy since 2014.
Built on science, delivered with care
Viphnorenrax was founded with a clear purpose: to make evidence-based sleep hygiene guidance accessible to everyone. Too often, people struggle with poor rest for years without knowing where to turn.
Our consultants draw on established behavioural sleep science to help clients understand and systematically improve their sleep patterns.
We are based at 137 Harley Street in London and offer both in-person and online consultations to clients across the United Kingdom.
