Set the scene
For a truly luxurious spell under the covers, make sure your bed linen is freshly laundered. Crisp, white and smelling sweet. Free of crumbs, stray bits of Lego, your other half's triathlete magazine, or whatever else tends to accumulate around the bed. Just for now, this is your sanctuary.
Plump your pillows
You want to lie back and think blissful thoughts. Not get a crick in your neck. So ensure your pillows are as soft and comfortable as they can be. If your pillows have been around for a while, you could be due a refresh. The test of a supportive pillow is to fold it in half. If it bounces back, it’s still good. If it stays folded up, it’s lost its cushioning qualities. Down and synthetic pillows need to be washed every six months, or replaced once they’ve lost their plumpness.
And switch off
The aim of your duvet day is to relax. To snuggle down and put the world on hold. If possible, resist the urge to have your phone or other devices to hand. If a Netflix film or a catch-up on iPlayer is your idea of luxury, by all means treat yourself. But avoid answering emails and texts, skimming social media or doing the weekly online shop. That can wait until you resume your everyday life.
