When I say "mask". I'm not talking any old one, but the Drowsy silk sleep mask
An adjustable wrap-around-the-head affair, this cult creation blocks out light, muffles noise, cushions eyes and won't mark skin. For pillow sprays, head straight for Drowsy Sleep's Sleep S.O.S Essential Oil Blend (£15.85
drowsysleepco.com). It's supposed to be deployed in a burner, but I drop it into the tub and on my bedding until I'm drunk on cedarwood, lavender, ylang ylang and vetiver.
