If, despite getting a good eight hours sleep a night, you're still depending on your morning coffee to wake you up, then follow the steps below for a better sleep that leaves you recharged.
Sleep quality: why it matters
In a talk hosted at the inaugural Women's Health Live, sleep scientist Dr Sophie Bostock joined leading trainer and the brains behind the Power Hour podcast, Adrienne Herbert, to chat all things sleep-related.
"In terms of the number of hours of sleep, we probably haven't changed that much over the past few years," says Dr Bostock.
"What has changed is sleep quality. We are now bombarded by things that get in the way of our sleep – phones, laptops and tablets are designed to mimic the same wavelength of light that you get with the midday sun."
How to improve your sleep quality
Try and go to bed at a reasonable hour
"We sleep in cycles,'" says Dr Bostock. "Of around 90 minutes. Stage one is a light doze, in which you're easy to wake up.
"Stage two is 'true sleep,' in which your heart rate slows down, your temperate drops, you breathe more slowly.
"Stage three is really physically restorative – it's when you repair your damaged cells and you hit it after around 45 mins of being asleep. Then, we cycle through REM sleep, which is when we dream, and back to one."
Why does this matter? Well, in the first half of the night, you skew towards the deeper sleep zones, which is why you are less likely to wake up.
As such, if you do go to bed at 2am, you're potentially missing out on greater sleep quality, by swerving this juicy slumber.
Put down your tech
Being on your phone right up until you turn the lights out affects the quality of sleep.
"If you're very sleep deprived, you may well still go straight to sleep after using tech," explains Dr Bostock. "But I promise you that your sleep is a lower quality than it would have been had you stopped using it an hour before."
Just because you can get to sleep doesn't mean that your sleep is optimal, so retire your devices 60 minutes before you want to go to bed.
Don't hit snooze
When it comes to protecting your sleep quality, this one is a biggie. "When you hit snooze, you are not getting beneficial sleep," says Dr Bostock.
By shaking yourself in and out of sleep, it's a weird, in-between ground that's not doing you any favours. "You'll also have a groggy feeling, known as sleep inertia," – and this can last for your whole day.
Know that you can increase your sleep quality
"Anyone who feels they've lost control of their sleep you can take it back. You are born knowing how to sleep, it's innate," explains Dr Bostock.
"But we lose track because of the environment we're in and unhelpful thinking habits and behaviours."
If you tackle the thoughts (for example, by using CBT techniques) and behaviours, then good sleep is in control.
Clear your mind with a to-do list
To prevent waking up in the middle of the night with a racing mind, Herbert recommends writing it out last thing at night.
"I write my to do list to empty my mind as my schedule changes all the time. I know I won't forget anything," she says.
Experiment with exercise
"The advice used to be to not exercise after 9pm as it heats the body up," says Dr Bostock. 'But there's a lot of natural variation.
"Some people should be doing yoga at the most, others can go running. It's worth experimenting with to see what works for you."
