Perhaps my fake lie-ins weren’t as clever as I thought, and this certainly explains some of my morning grumpiness. So, how does one master the art of setting a good alarm to avoid hitting snooze?

“The most important point to consider is to set your alarm for the same time every day, even at weekends,” says Dr Joyce. “Try not to vary by more than about half an hour. The circadian rhythm (body clock) is determined by chemical and physiological changes that fluctuate throughout the day, including the hormone cortisol, which helps us feel alert in the morning, and melatonin, the hormone that tells the body when to sleep.”

She explains that having a consistent schedule makes it easier for our body clock to predict what time to release these hormones, helping us feel alert or sleepy at roughly the same time each day.

Leslie says it can be helpful to remove mobile phones from the equation and to keep an old-fashioned alarm clock in your bedroom. “Ideally, it’s out of reach, so you’re out of bed before you know it,” she says. She also advises “making the bedroom really nice before bed, throwing open the curtains first thing, considering some motivational morning affirmations, exercise or meditation, and a pleasurable breakfast routine”.

“I set multiple alarms to trick my brain into thinking it’s had a lie-in – is that why I’m grumpy in the mornings?”
