Don't be caught napping over bedtime routine

With winter fast approaching, those weekend lie-ins are more tempting than ever. But, as an expert explains to Kate Whiting, they could be doing us more harm than good

Let's face it, most of us could do with getting a bit more sleep, right? Thank goodness for the weekends, when we can snatch a couple more hours of shut-eye (if we're lucky), and make up for those missed zzzzs during the week.

Soon - on Sunday, October 25 - the clocks will be going back an hour, too, and those long, dark mornings make staying in bed even more tempting.

But, according to many experts, that's not how it works. In fact, not only does an occasional lie-in not make up for a lack of sleep on other nights, but hitting the snooze button could be making things worse, and we'd be far better off waking up at the same time every day, seven days a week.

ALL ABOUT THE ROUTINE

"We should aim to stick to a good routine at least most of the time, and the phase before midnight is important," says Dr Nerina Ramlakhan, Silentnight sleep expert and author of Tired But Wired: How To Overcome Sleep Problems: The Essential Sleep Toolkit.

And that routine isn't just about what time our head hits the pillow and we actually close our eyes - what we're doing in the lead-up to bedtime can be important, too, if we're to properly benefit from a deep, restorative sleep.

"Our circadian timer (the sleep clock in the brain) runs on a rhythm which functions optimally when it works to a regular routine," Ramlakhan adds.

"This rhythm is influenced by the light/dark levels, which then influence the amount of melatonin (a sleep hormone) that we produce.

"Too many people in today's busy world try to work against this rhythm, spending too much time in front of screens. But the blue light from these devices and the dopamine-induced alertness both disrupt the clock mechanism."

HOW DO SLEEP CYCLES WORK?

We sleep in 90-minute cycles. Each cycle consists of five phases: light sleep, which is phase one and two; deep sleep, which is phase three and four; and REM sleep, which is phase five.

"Phases one and two are the preparation for the deep sleep phases," explains Ramlakhan. "Deep sleep is what we all need, as it heals body, mind and spirit. REM sleep is when we dream and sort out our mental 'filing cabinets', which is important for learning, memory consolidation and our ability to focus and concentrate."

DO WE REALLY NEED TO BANISH WEEKEND LIE-INS?

Of course, routine means, well, sticking to a pattern, and your body clock isn't going to make allowances for breaking that routine at the weekend.

With this in mind, Ramlakhan advises that long Sunday morning lie-ins are best avoided. But, she adds, we would be less reliant on them to help us catch up on energy if we had a good sleep routine in the first place.

Ever wake up shortly before your morning alarm is due to go off? Yet more proof that our brains like routine when it comes to successful slumber.

"Getting into regular habits does neurologically programme the mind, making it easier to pre-empt our alarm call," says Ramlakhan, who notes that too much sleep can be bad for us, too. And it's not just a lack of sleep we need to be careful of.

"It causes sluggishness and fatigue and can also lead to weight gain, digestive problems and other health problems due to secondary effects," she explains. "Additionally, people who oversleep are more likely to follow poor dietary patterns, exercise less, and even suffer mental health problems."

To strike the perfect balance, start getting into a sleep routine that involves going to bed well before midnight, then rising at a similar time each day, and not lazing in your bed just because you can.
