With so much going on in our hectic lives, is it wise to ‘waste’ time every day… sleeping? With so much anxiety, fear, loneliness and everything going on inside and around us, it can be hard to focus on a bedtime routine and improving our sleep. Let’s discover why quality is just as important as quantity for a sound and restorative sleep.
What is Sleep Quality?
Quite simply, sleep quality is a measure of how well you sleep. Here are some key indicators of sleep quality:
- You spend a minimum of 85% of your bedtime asleep
- It takes you 30 minutes or less to fall asleep
- You don’t wake up more than once a night
- You don’t stay awake longer than 20 minutes when you do wake up in the middle of the night
- You feel rested when you wake up
Importance of Sleep Quality
Sleep can impact all areas of your life. For instance, after a poor night’s sleep, you may find yourself in a mental fog. This can lead to poor decision making, memory problems, and slower reaction times. This in turn makes you more prone to injuries and accidents, not to mention, poor performance for any task.
You’ll also find it harder to regulate negative emotions and stay calm under pressure.
Poor sleep quality also increases your risk for heart disease, depression, various cancers, Alzheimer’s disease, Parkinson’s disease, ulcers, and obesity.
Sleep Quality and Immunity
Do you want to boost your immunity? Improving your sleep quality is the right prescription!
Good sleep quality improves how well your T cells fight off infections. T cells are immune cells that fight pathogens in your body such as virus-infected cells and tumor cells. In order for your T cells to fight these pathogens and abnormal cells, they need to be in direct contact with them. Sticky molecules called integrins promote this contact; think of them as the glue that your T cells need to stick to pathogens and cells.
Cortisol, a key stress hormone, decreases the stickiness of these integrins. When you sleep well, your stress hormones fall, making the integrins stickier and T cells more effective, increasing your immunity.
There are 5 natural ways to improve sleep quality:
Exercise During the Day
Aerobic and cardio exercise are important for many aspects of health, including sleep quality. A study found that in patients with chronic insomnia, engaging in moderate aerobic exercise reduced the time it took to fall asleep by 55% and the total amount of nighttime wakefulness by 30%.
And you don’t need much aerobic exercise to sleep well. In fact, just 10 minutes of cardio exercise can dramatically improve your sleep quality. So, go for a walk or whatever gets your heart pumping.
Avoid Caffeine in the Evening
In order to sleep better, you want to watch your caffeinated beverage consumption. That’s because caffeine blocks the sleep-activating chemicals in your brain. This makes it harder for you to both fall and stay asleep. Furthermore, caffeine decreases your REM sleep, the part of your sleep cycle where you have the most restorative sleep.
And it takes time for caffeine to clear from your system. That’s because its half-life is 6 hours. So, it takes a full 24 hours to clear from your system completely. Ideally, you want to have your last cup of coffee or other caffeinated beverage at least 6 hours before going to bed as studies show that consuming caffeine up to 6 hours before bed decreases sleep quality.
Avoid Blue Light at Night
Blue light has a big impact on your sleep quality. That is because blue light decreases the production of melatonin, your sleep hormone, making it harder for you to fall asleep.
Unfortunately, a lot of our modern devices emit blue light. These include television, laptops, tablets, and cell phones. Using these devices 2 hours before going to bed affects your sleep quality in several ways. It makes it harder to fall asleep and reduces the rejuvenating REM sleep phase, making you feeling less rested even after sufficient hours of sleep.
How can you limit your blue light exposure in the evening? I you can’t avoid watching your favorite show, sit as far away as possible from the TV and don’t try to sleep right away after turning it off, do some chores, read a book, take a walk or meditate…as possible to avoid the blue light emissions.
Create a Comfortable Sleep Environment
Your sleep environment plays a big role in how well you sleep. Too hot or too cold a sleep environment can affect your sleep quality. Ideally, you want your room to be at a temperature between 65 to 70°F. Find the right pajamas to find the right body temperature while sleeping. If your feet get cold, wear some socks.
Make sure that you have a comfortable mattress and pillow so that you’re not tossing and turning in the middle of the night. Additionally, you want your room to be quiet. If you live in an area where you have night-time traffic or loud neighbours, this can be easier said than done. In that case, you may want to invest in a good pair of ear plugs or use a white noise machine, even a fan can do the job.
Watch out for the humidity of your bedroom, particularly if you live in an arid environment. Dryness can cause headaches and sinus congestion, which may interfere with your sleep quality.
Follow a Bedtime Routine
While participating in high-energy activities just before bedtime decreases sleep quality, the opposite is true. Having a daily relaxing bedtime routine increases your sleep quality by signalling to your body that it’s time to sleep.
One of the best things you can do as part of your bedtime routine is meditate. In a 6-week study in which insomnia participants practiced mindfulness-based meditation, such as mindful framing, participants halved the amount of time it took them to fall asleep. In addition, at the end of the study, 60% of the participants no longer had insomnia.
You can also relax by having a warm bath, deep breathing, listening to some relaxing music, or a combination thereof. I avoid stressful activities such as watching news or engaging in difficult conversations. For my body, I don’t take any food or alcohol several hours before going to bed and have an Ayurvedic self-massage mixing myself body butter and ashwagandha fluid.
Once I’m in bed, I start clearing my mind, focusing on my 5 senses: how my skin touches the cotton of the sheets and my pyjamas, the sounds of white noise, the residual smell and taste and I watch the lights and forms appearing when I close my eyelids.
Let’s learn how to leverage our sleep as a powerful way to decompress and reduce our anxiety every night. By improving the quality of your sleep, you’ll be better equipped to handle life’s stressors with a source of unlimited energy and resilience.
