SE1 Guy's and St Thomas's Sleep Disorder Centre One of the few sleep clinics in the country --this centre deals with all types of sleep problems - neurological, respiratory, and stress-related disorders. St Thomas' Hospital, Lambeth Palace Road, SE1 (020-7928 9292, ext 6867). www.guysandstthomas.nhs.uk. W1 The Hale Clinic Therapist Deborah Mitchell uses Lia Therapy (a combination of lymphatic drainage, incandescent massage and acupunture) to treat insomnia. The treatment is performed on the face and shoulders. During the session Mitchell claims the brainwave cycles drop from 22 cycles per second (stressed) to 11 cycles per second (dream state). It also helps to calm and rebalance the hormones in the brain responsible for sleep. As it releases collagen and elastin in the face, it also helps to reduce dark circles and puffy eyes. A one-hour treatment costs £125. 7 Park Crescent, W1 (08701 676 667). www.haleclinic.com.
