Bedtime, for many of us, can be a frustrating experience: we all know that we’re supposed to get that elusive seven hours of shut-eye each night, but it can sometimes feel like an impossible task. Not so for Holly Willoughby, who sticks to the strictest of bedtime regimes to ensure that she feels awake enough to tackle her early-bird stint on ITV’s This Morning each day.

“I’ll be in bed at 9pm with lights out 9.30pm,” she tells Red magazine. “I am half woman, half sloth!”

However, Willoughby admits that there’s more to it than just popping her head on a pillow and hoping for the best. Instead, she needs “headspace” to help her to “process the day, which is really hard sometimes” – and she does this during her “bath-time”.

“[It’s] my switch-off,” she admits.

However, there’s more to Willoughby’s evening bath than a stream of bubbles: instead, she raids her kitchen cupboards for one essential – but very purse-friendly – ingredient, to help her achieve a truly blissed-out state.
