Sleep. We all do it and we all need it. But while it’s something we should be able to do with our eyes closed, a large amount of us have trouble getting it. According to founder of The Fast 800, sleep expert and Medibank Ambassador Dr Michael Mosley, more than half of adult Australians are suffering from at least one chronic sleep symptom that is affecting their ability to live a healthy, happy life. Given sleep is so important to us, this is a worrying statistic. According to Dr Mosley, ‘too little sleep can devastate your body, brain and microbiome (gut bacteria), dramatically increasing your risk of developing a range of chronic conditions such as obesity, type 2 diabetes and dementia.’

If you’re someone who isn’t getting enough shut eye the good news is, there are ways you can improve your sleep quantity and quality to help you wake up feeling refreshed. Here are a few of his suggestions to help you S.L.E.E.P. better.
Stop drinking caffeine from 1:30pm
Are you someone who enjoys a cup of coffee for a bit of an afternoon pick me up? According to Dr Mosley this is a big no-no. Putting caffeine into your system anytime after 1:30pm will affect your ability to sleep.
Leave no sleep distractions in your room
Do you scroll through social media in bed? Don’t! “Your bedroom should be for sleep and for sex,” says Dr Mosley, “nothing else.” Contrary to what many people may have heard, the issue isn’t the effects of the blue light coming from your phone but rather the mental stimulation from the endless scrolling. If you want to take sleep seriously, you need to remove all distractions from your bedroom.
Exercise early when you wake-up
There was once a time when the sun was our natural alarm clock, and with good reason. Getting outside in the morning and doing exercise in the sun releases serotonin, which tells our bodies to wake up!
Eat nothing before bed
Sorry to be the bearer of bad news, but if you’re someone who likes to wind down with a cup of tea and a biscuit in the evenings you should reconsider. Eating anything around 2-3 hours before bed increases your body temperature, which can stop you getting to sleep.
Prepare for sleep
If you go to bed with thoughts in your head you may find it harder to fall asleep. Try a short meditation before bedtime to help you relax and switch off. It probably comes as no surprise that stress is one of the main causes of insomnia. Expressing gratitude is a proven way to reduce stress, so if you’re stressed you could also try listing three good things that happened to you during the day just before you get into bed.
Don’t just lie there
OK, so you’ve followed all the tips but you’re still lying there tossing and turning? It may seem counter intuitive, but Dr Michael Mosley says the best thing to do if you haven’t fallen asleep within roughly 20 minutes of closing your eyes (estimate, don’t watch the clock), is get out of bed and out of your bedroom. Ideally, you’ll spend this time doing something soothing such as reading a book, meditating or listening to calming music to help get you in the mood for sleep again.
Wake up to sleep
Although some of us find it difficult to fall asleep, the most common sleep problem is waking in the middle of the night then struggling to get to sleep again. If this is you, Dr Mosley has some suggestions.
- Try a breathing technique – While there are lots of different breathing techniques which Dr Mosley outlines in Fast Asleep, his chosen method is the 4-2-4. Basically, breathe in through your nose while you count to 4. Hold your breath for 2, then breathe out through your mouth for another 4. A few minutes of this should help you relax.
- Challenge your thoughts - Do crazy thoughts invade your head in the middle of the night? You could try challenging them. Here’s an example from Fast Asleep.
“I won’t get to sleep and if I don’t, I will feel really tired tomorrow and won’t be able to function”
Challenge: “I’m sure I will get to sleep, I normally do. But even if I don’t, it will be fine.”
- Don’t just lie there - Again, if none of these techniques have worked after about 20 minutes you should get out of bed. The main thing is to try not to worry about the fact you’re awake or what that means for the next day.
