How to get more deep sleep
It is that time of the year again! Winter is setting in and, as the clocks go back this weekend, that extra hour of sleep we get from Saturday to Sunday is one of the little wins that we all look forward to.
After all, “adults need between 7 and 9 hours of sleep each night”, right? But did you know that the quality of sleep you get also matters? If you find yourself getting enough hours of sleep at night but wake up still feeling like your body isn’t fully rested, chances are you’re not getting enough deep sleep. This is the elusive sleep stage when brain waves are at their lowest frequency - muscles relax, breathing slows, and you are less prone to awakening.
The technical name for deep sleep is Slow-Wave Sleep (SWS) and is the sleep stage responsible for healing and repairing your body, replenishing cells and revitalising the immune system. While the amount of deep sleep needed varies with age, spending at least 20% of the night in deep sleep is a good goal to set.
So how do you achieve it? According to the National Sleep Foundation, here are some steps you can take to improve your time in deep sleep all year round:
1. Stick to a Sleep Schedule
Decide on your bedtime and wake up time, and stick to it - even on the weekends! This will help regulate your body's clock, which in turn, helps you fall asleep and stay asleep through the night. In under a week, you should fall into a regular sleep pattern, which increases your chances of getting some much needed deep sleep.
Your body will also naturally wake up at the same time, meaning less reliance on your alarm, while reducing that feeling of needing to drag yourself out of bed.
To make things easier, smartphones now have the option to create a sleep schedule, where you input how many hours of sleep you want to get and your waking time. It will also notify you at your selected bedtime and even alert you beforehand so you can make sure you get to bed in time.
2. Eliminate distractions
Distractions like noise and light before or during bedtime cause restlessness and reduce your chances of getting any proper sleep. Sleep in a dark, cool room and make sure your phone is on silent and away from your bed to avoid being awoken by notifications. Using an eye mask and earplugs are a great way to block out light and sound throughout the night.
Remember to also stop using your screens in the hour before bedtime - this reduces our exposure to blue light which indicates to the body it’s daytime, which can make it more difficult to fall asleep and enter the deeper stages of sleep.
3. Avoid alcohol or caffeine before bedtime
If you find yourself tossing and turning at night, it could be due to alcohol or caffeine. While alcohol can make you fall asleep quicker, it messes with the quality of sleep because it means the body is less likely to move through the various stages of the sleep cycle.
Cut down your caffeine in the later stages of the day - it can help to set a cut off time of no caffeine in the 6 hours before you sleep; even if you no longer feel the effects of the caffeine, it can still have an impact on your circadian rhythm. Sugar is another culprit of sleep deprivation, even though it can help you feel sleepy (due to the sugar crash) it can negatively affect your sleep quality and wake you up at night.
4. Create a cool and comfy sleeping environment
Being comfortable is important to getting a deep night's sleep. There are a number of ways to get comfy at night, but sleeping on a comfortable mattress and pillows is always the first step. Look at how you can improve your room and make it more attractive and inviting for sleep, for example by removing allergens that might affect you.
Try to also keep your sleeping room cool, as many experts agree that a cooler temperature is beneficial for a good night’s sleep - the ideal temperature is 18.3ºC (or 65ºF). While this might sound chilly, it works with your body’s natural temperature flow as a drop in your body’s temperature naturally occurs during the initial stages of your sleep cycle. This is because a lower core temperature makes you feel sleepy, whereas a higher temperature helps you stay alert during the day.
Conclusion
Remember that the most important factor in increasing your deep sleep is to allow yourself adequate total sleep time. By going to bed too late / getting up too early, your deep sleep and even REM sleep are automatically reduced. Deep sleep is critical to our health and so it is important to get as much of it as we can, especially in today’s ever busy and stressful world.
If you’re still having trouble getting enough sleep, don’t hesitate to speak with your doctor or find a sleep professional. They can prescribe certain supplements like CBD Oil, Ginkgo biloba, and Valerian root, which may aid in sleep, relaxation and stress reduction.
