Guy has been studying human physiology for 23 years, 18 of which have been devoted to sleep research and the prevention of sleeping disorders.
He graduated with a first class BSc Honours degree from Glamorgan University, then an MSc (Distinction) at Kings College London in Human and Applied Physiology, and finally completed his doctorate at Imperial College London. Whilst studying there, he worked in the sleep research laboratories of the Royal Brompton and Charing Cross Hospitals, where he investigated the effects of sleep apnoea on the regulation of the human brain.
He is a leading figure in the area of chronic insomnia, pioneering the use of Acceptance and Commitment Therapy (ACT) and Mindfulness treatment. He has worked with thousands of insomnia sufferers over the last 10 years at his London-based clinic and around the world, and has set up the Sleep School to help stop insomniacs needlessly suffering around the world. He regularly runs GP training sessions within the UK and trains Health Care Providers worldwide in the development of ACT for Insomnia.
He also works with many of the world’s leading organisations to improve their employees’ sleep through the Sleep School’s Professional Programme.
He is a published author (The Sleep Book – How to sleep well every night – Orion 2014) and launched the Sleep School App for Insomnia and the Sleep School App for Professionals: two highly interactive audiovisual support tools.
He contributes to television and radio, regularly appearing on both the BBC and ITV news shows. In 2017 he presented on a BBC Panorama documentary called Sleepless Britain.
