Although the importance of excellent sleep to health has long been recognized, no universal standard has yet been established by the sleep science community. Instead, individuals tend to rely on their own subjective judgments when assessing the quality of their sleep. The term “quality sleep” can mean different things to different people depending on their lifestyles, habits, and requirements. Numerous elements, such as sleep disruptions, bedroom atmosphere, and daytime sleep routines, are consistently reported by sleepers when assessing the quality of their sleep. A person’s perception of the quality of their sleep is also influenced by their day-to-day events, such as how refreshed they feel upon awakening.
However, there is no correlation between the number of hours you sleep and how well you sleep. Another way of saying this is that people can get a lot of sleep, but it may not be quality sleep if it is interrupted frequently. Even though sleep quantity and quality are evaluated in distinct ways, sleep hygiene can affect both.
What Is Sleep Quality?
Quantity of sleep is not the same as quality of sleep. Quantity refers to how many hours of sleep you get each night, while quality evaluates how well you rest.
Quantifying sleep is easy because it only takes a few moments to tell if you’re getting enough shut-eye each night (usually defined as 7-9 hours for adults). In some ways, determining the quality of one’s slumber is more of an art than a science. Some aspects of a good night’s sleep include:
- Within 30 minutes after getting into bed, you’re fast asleep.
- The majority of nights, you get eight hours or more of sleep without waking up.
- You can get the amount of sleep that scientists say is ideal for your age bracket.
- If you awake, you go right back to sleep within 20 minutes.
- When you first open your eyes in the morning, you feel refreshed and revitalized.
Why Is Sleep Quality Important?
For a variety of reasons, getting a good night’s sleep is crucial. An crucial part of being human, right up there with oxygen, food, and water, is sleep. One’s ability to feel refreshed and ready to take on the next day is impacted, and daytime sleepiness is reduced. Quality sleep is beneficial to one’s mental and physical wellbeing and enhances one’s quality of life.
Human development is enhanced by sleep as well. Therefore, younger children, adolescents, and newborns have a greater sleep requirement than adults do. Sleep is important for the health and recovery of people of all ages, both as a means of maintaining good health and of preventing illness.
The consequences of insufficient sleep or poor quality sleep are numerous. Physiological causes include, but are not limited to, an elevated threat of developing a stroke, heart disease, or hypertension. It’s also possible to experience mental consequences, such a rise in irritation or the onset of anxiety or sadness.
Your own or others’ safety may be compromised by poor sleep. A sleep-deprived driver, for instance, poses a serious threat to themselves and others on the road.
What Factors Affect Sleep Quality?
Reduced quality of sleep may result from neglecting to practice excellent sleep hygiene. Further factors include:
- Disrupted sleeping patterns. By maintaining a regular bedtime and wake time, you can enhance the quality of your sleep.
- The place where one sleeps. There shouldn’t be any music playing or bright lights on in the bedroom. Avoiding electronic devices (TVs, computers, and phones) that emit blue light in the hours leading up to night is recommended.
- Overindulging in a caffeinated or alcoholic beverage. These drinks may make it difficult to get to sleep or stay asleep.
- Drugs. Diuretics and other medications might cause frequent toilet breaks, waking their users at night. Both over-the-counter (OTC) and prescription sleep aids carry the risk of drowsiness and other unwanted side effects during the day.
- Snoring. Some snoring is acceptable, but chronic or severe snoring can disrupt sleep for both the snorer and their bed mate. This form of snoring has been linked to OSA as a possible indication (OSA).
- Disturbances in the night’s rest. Poor sleep quality is often the result of sleep disorders like insomnia, which make it difficult to fall asleep or stay asleep. One of the nocturnal symptoms of narcolepsy is a tendency toward nightmares and frequent awakenings, both of which can have a negative impact on the quality of sleep.
- Disturbances in mental health. Sleepless people often suffer from comorbid depression and anxiety. One result of this is sometimes restlessness or an inability to settle down and get a good night’s sleep.
The quality of your sleep may also be affected by things like your food, the amount of exercise you get during the day, the distance you travel, and any aches or symptoms you may be experiencing.
How Can You Calculate Your Sleep Quality at Home?
The first step in determining the quality of your sleep in the comfort of your own home is to answer a few simple questions about your typical nighttime routine.
How Long Does It Take You To Fall Asleep?
While everyone’s time to sleep is different, the Insomnia Severity Index classifies poor sleep as occurring when it takes 30 minutes or more to fall asleep on a consistent basis.
How Long Are You Asleep in Bed?
Sleep inefficient people spend less than 85% of their time in bed actually sleeping.
How Often Do You Wake up During Sleep? For How Long?
It’s recommended that it takes fewer than 20 minutes to fall asleep again if you want a good night’s rest.
Questions concerning your daily and awakening routines to think about are:
- Do you find it hard to rise and shine every day?
- Do you find it hard to concentrate or remain awake during the day?
- Do you frequently find yourself falling asleep or napping?
Answering these questions and keeping track of your sleep by recording your daily habits and activities just before night can be aided by keeping a sleep diary. Keeping a sleep journal might be useful in figuring out what influences your quality of sleep. If necessary, you can then make changes to your routine or discuss your findings with your doctor to receive expert advice.
Signs Your Sleep Quality Needs To Improve
You might be receiving bad sleep if you have any of these symptoms.
- After getting into bed, it takes you longer than 30 minutes to nod off.
- A number of times each night, you find yourself awake.
- Whenever you awake in the middle of the night, you lie there for a minimum of 20 minutes.
- Not more than 85% of your time in bed is spent dreaming.
- You wake up feeling exhausted, and it’s hard to maintain focus on the day’s tasks. To maintain your energy levels, you might be increasing your intake of caffeine.
- You have been experiencing skin breakouts and have noticed that your eyes are becoming swollen, red, or have developed dark circles or bags.
- You’re gaining weight and finding that you’re constantly hungry, especially for unhealthy foods.
- You’re feeling more anxious, drained, and irritable than normal.
- You have been told that you suffer from sleeplessness.
Reasons for Poor Sleep Quality
There could be many causes of your poor sleep quality. Inadequate sleep hygiene, stress, sleep apnea, or a persistent health condition or sleep disorder are all possible triggers.
Poor Sleep Habits
The quality of your sleep can be negatively impacted by things like sticking to an inconsistent sleep schedule or ingesting excessive amounts of caffeine or alcohol. Two major contributors to poor sleep quality among nursing students were smoking and everyday coffee intake, according to a recent study. However, despite its reputation as a sleep aid, alcohol can actually cause sleep disruptions.
Stress and Anxiety
Stress, despair, and anxiety all contribute to subpar quality of sleep. Sleep deprivation and the accompanying sleeplessness only make matters worse, perpetuating the vicious cycle.
Chronic Health Conditions
Insomnia and reduced sleep duration are often symptoms of long-term health problems. Diseases of the lungs, airways, and other organs, as well as kidney and bladder problems, cancer, fibromyalgia, and chronic pain are all on this list. Unfortunately, the symptoms and distress brought on by stress and worry can be exacerbated by poor sleep quality.
Sleep apnea is characterized by brief interruptions in breathing during sleep, audible as snoring, gasping, or choking. The brain has to initiate breathing anew, even if the person isn’t consciously aware that they’re awake. People who suffer from sleep apnea frequently report problems with daytime sleepiness and low energy levels.
Undiagnosed Sleep Disorder
Some sleep problems go untreated until the affected individual seeks medical attention for unrelated symptoms, such as poor sleep quality, or until their bed partner brings their attention to the problem. For instance, people with periodic limb movement disorder (PLMD) have trouble sleeping because their legs jerk involuntarily throughout the night. This leads to daytime weariness and impaired focus. Poor sleep quality and daily weariness are common complaints among those who have narcolepsy.
How To Improve Your Sleep Quality
Fortunately, it may be as easy as practicing better sleep hygiene to enhance the quality of your nights’ rest. Similar to how excellent dental hygiene involves brushing and flossing on a regular basis, effective sleep hygiene entails constantly engaging in behaviors that promote restful nightly slumber.
Use these suggestions to get a better night’s rest.
- Leave the TV and electronic devices alone at least 30 minutes before bedtime. The blue light given out by electronic devices is mistaken by the brain for natural light, causing you to stay awake longer than you would like.
- Make your room a cool haven of darkness and silence. Reduce the temperature to to 60 degrees Fahrenheit, and add some blackout drapes and white noise to help you drift off.
- Maintain a regular sleep-wake schedule. Maintaining a regular bedtime and waking time helps your brain learn these natural rhythms.
- Make sure you’re giving yourself adequate time to sleep each night. Adults should sleep for at least 7–9 hours nightly.
- Develop a soothing nighttime ritual. Pick things that put you at ease, like a warm bath, an audiobook, or writing in a journal. The brain learns to associate the order in which you do these tasks as a cue for bedtime.
- Try to cut back on the coffee and alcohol. Both of these medications have long-lasting effects on your body and can prevent you from getting restful sleep. Don’t consume any alcoholic beverages or caffeine within three hours of bedtime.
- The morning is the best time to soak up some rays of sunshine. You may reset your internal body clock with just 15 to 30 minutes of sun exposure in the morning.
If you’ve tried these solutions and are still having difficulties sleeping, it may be time to see a doctor. They may suggest a variety of therapies and medications to help you get a better night’s rest.
How Do Professionals Evaluate Sleep Quality?
Not everyone is getting enough quality sleep. You may improve your chances of getting a restful night’s sleep by adopting certain healthy routines during the day and making your bedroom more conducive to sleep at night.
Seek medical advice if you are having trouble falling asleep or staying asleep. Sleep researchers and instruments like the Pittsburgh Quality Sleep Index allow medical professionals to assess how well people sleep (PSQI). The PSQI, or the Sleep Behavior Questionnaire, is a set of questions used in both clinical and research settings to assess sleep-related behaviors. Patients rate themselves on seven different dimensions, including how well they slept, if they had any problems while sleeping, and how their condition affected them during the day. The answers to these questions are analyzed by trained professionals, who then devise interventions aimed at enhancing the patient’s rest.
If you have suspicions that you suffer from a sleep problem like narcolepsy or sleep apnea, a sleep study may be in order. Polysomnography is a standard diagnostic procedure in which patients are studied in a sleep lab for an entire night. Evaluations of the patient’s liver, heart, and lungs are also performed alongside tests like multiple sleep latency tests, which assess the patient’s ability to fall asleep, the maintenance of wakefulness test, which measures the patient’s level of daytime drowsiness, and others.
However, these assessments are limited in their accuracy because of the subjective nature of sleep evaluations. Instead, the information gleaned from these tests is specific to the individual’s sleep habits and might shed light on any behavioral anomalies that may be to blame for subpar rest.
