In a world that never sleeps, it's time to awaken to the true essence of quality rest. Welcome to a revealing journey to unraveling the mysteries of sleep and discovering the transformative power it has on our lives.
What Is Sleep Quality?
Sleep quality goes beyond the mere act of slumber; it encompasses the depth, restfulness, and restorative nature of our precious shut-eye. It's the elusive state of bliss where our bodies and minds find solace, rejuvenation, and healing.
According to the National Library of Medicine, sleep quality is “an individual's self-satisfaction with all aspects of the sleep experience.” and has four key attributes including sleep efficiency, sleep latency, sleep duration, and wake after sleep onset.
The importance of sleep quality cannot be overstated, as it plays a vital role in our overall well-being. When our sleep quality is compromised, it can have detrimental effects on our health and increase the risk of diseases and negative health outcomes.
But how do we measure our sleep quality? Let's dive deeper.
Measuring Sleep Quality
To understand our sleep quality, we need to explore its four key aspects. Sleep duration, or the number of hours we spend asleep, is just one piece of the puzzle. Equally important is sleep efficiency, the percentage of time spent asleep while in bed. Additionally, factors like sleep latency (time taken to fall asleep) and the number of awakenings during the night contribute to the overall picture. By evaluating these parameters, we can uncover our sleep quality and make informed choices to enhance it.
Sleep Efficiency
Sleep efficiency measures the proportion of time spent asleep in relation to the total time spent in bed. It reflects how effectively we transition from wakefulness to sleep and maintain a restful state throughout the night. To calculate sleep efficiency, divide the total sleep time by the total time spent in bed, and multiply the result by 100. For example, if you spend 7 hours asleep out of the 8 hours you spend in bed, your sleep efficiency would be 87.5%.
Sleep Latency
Sleep latency refers to the time it takes to fall asleep after lying down in bed. It measures how quickly we transition from wakefulness to sleep. A shorter sleep latency indicates an easier time falling asleep, which is generally considered favorable. For instance, if it takes you approximately 15 minutes to fall asleep after getting into bed, your sleep latency is 15 minutes.
Sleep Duration
Sleep duration simply refers to the total amount of time spent asleep during a sleep period. It takes into account the length of time from the moment you fall asleep until you wake up. The recommended sleep duration varies depending on age and individual needs. As an example, if you sleep for 7 hours and 30 minutes during the night, your sleep duration is 7.5 hours. Sleep duration has an important role in our overall sleep quality which is closely related to our mental health. A recent study has found that high levels of anxiety and depression in young adults are positively correlated with a higher workload. (source: Europe PMC)
Wake After Sleep Onset (WASO)
Wake after sleep onset represents the total time spent awake during the sleep period after initially falling asleep. It includes any awakenings that occur throughout the night, whether they are brief or prolonged. WASO provides insights into the fragmentation of sleep and the number of disturbances experienced during the night. For example, if you wake up three times for a total of 30 minutes during the night, your WASO would be 30 minutes.
So, How to Improve Our Sleep?
From establishing a consistent sleep schedule to creating a serene sleep environment, there are countless strategies to improve our sleep quality. Here are five ways to improve our sleep quality.
1. Establishing a Consistent Sleep Schedule
One of the fundamental pillars of good sleep is maintaining a consistent sleep schedule. This means going to bed and waking up at the same time every day, even on weekends. By aligning our body's internal clock, known as the circadian rhythm, with a regular sleep routine, we can promote better sleep quality and enhance the efficiency of our sleep cycles.
2. Creating a Sleep-Friendly Environment.
The environment in which we sleep plays a significant role in our sleep quality. Optimizing our sleep sanctuary by ensuring our bedroom is cool, dark, and quiet. Consider using blackout curtains, earplugs, or a white noise machine to block out external disturbances. In addition, it’s a good idea to invest in a comfortable mattress, pillows, and breathable bedding that suits our personal preferences and promotes optimal comfort.
3. Practicing Relaxation Techniques
Relaxation techniques before bedtime can help calm our minds and prepare our bodies for a restful night's sleep. Engage in activities such as reading a book, practicing deep breathing exercises, or listening to soothing music. Avoiding stimulating activities or screen time close to bedtime is important, as it can interfere with our ability to relax and fall asleep easily.
4. Limiting Exposure to Electronic Devices
The blue light emitted by electronic devices, such as smartphones, tablets, and televisions, can disrupt sleep patterns by suppressing the production of melatonin, a hormone that regulates sleep. Minimizing our exposure to electronic devices at least an hour before bedtime is essential. Instead, we can opt for activities that promote relaxation and create a screen-free wind-down routine.
5. Prioritizing Regular Exercise
Physical activity during the day has been shown to improve sleep quality. Engaging in regular exercise, whether it's a brisk walk, yoga, or a workout session, can help reduce stress, increase relaxation, and regulate our sleep-wake cycle. However, exercising too close to bedtime can stimulate our bodies and make it difficult to fall asleep.
By incorporating these popular strategies into our daily routine, we can take significant steps toward enhancing our sleep quality. Remember, each person is unique, so it may take some trial and error to find the combination of methods that works best for you.
What Is a Good Quality of Sleep?
Good quality of sleep refers to a state of restfulness and rejuvenation that allows you to wake up feeling refreshed, alert, and ready to take on the day. While individual experiences may vary, certain characteristics are generally associated with a good quality of sleep including sufficient duration, uninterrupted, restorative sleep, and balanced sleep stages.
Is 70 Sleep Quality Good?
When it comes to sleep quality, a score of 70 is considered fair to good, but not exceptional. Sleep quality is typically assessed using various methods, including sleep questionnaires or activity tracker devices such as Fitbit that monitor sleep patterns and provide a sleep quality score. While a score of 70 may indicate that certain aspects of your sleep are satisfactory, there is still room for improvement.
If you're consistently scoring around 70 and feel that your sleep could be better, it may be worth exploring strategies to optimize your sleep environment, establish a consistent sleep schedule, practice relaxation techniques, and address any potential underlying factors that could be impacting your sleep quality.
All in All
Quality sleep is not a luxury; it's a necessity for our physical, mental, and emotional well-being. By understanding the depth of our sleep quality, we can harness the transformative power of rest and awaken to a world where vitality and resilience flourish.
