Although it is well-known that quality sleep is crucial for overall health, experts don’t agree on a single definition of quality sleep. Sleep quality is often determined by the sleepers themselves. Because everyone is different, the factors that determine sleep quality vary widely. When evaluating their quality of sleep, there are several factors that sleepers will report, such as sleep disturbances, sleep environment, and sleep habits. Quality sleep is also affected by daytime experiences like feeling refreshed and rested after waking up.
But sleep quality and quantity are not necessarily related. Also, while people can sleep for long periods of time, it is possible to have disturbed sleep, which is not considered quality sleep. While quality and quantity of sleep are two different things, they are both affected by sleep hygiene.
Why Is Sleep Quality Important?
There are many reasons why sleep quality is so important. Sleep is essential for human health. It can affect one’s ability to feel refreshed and energized for each day, and it can also reduce daytime sleepiness. Good sleep contributes to a high quality of life and supports physical and mental health.
Human growth is also dependent on sleep. Children, teens, and infants need more sleep than adults. All ages require sleep to prevent illness and recover from injury or illness.
Negative effects of poor sleep quality or sleep deprivation may result. These negative effects can be physiological and include an increased risk of stroke, heart disease and high blood pressure. These negative effects can also have psychological consequences, such as an increase in irritability or the development of anxiety and depression.
Insufficient quality sleep can lead to safety issues for you and others.
Driving while you are sleepy can result in an accident, injury or even death.

- An irregular sleep schedule. Getting up and going to bed at the same time every day can improve sleep quality.
- Bedroom environment. It should be dark and quiet without too many lights. Avoid blue light from electronic devices such as phones, TVs, and computers. This can increase alertness, so avoid it at night.
- Too much caffeine or alcohol can cause insomnia.
- Drugs. Some prescription medications, like diuretics and others, can increase the need for frequent bathroom visits, which can cause insomnia. Over-the-counter or prescription sleep aids can cause insomnia and other side effects.
- Snoring. While some snoring may be normal, excessive snoring could cause problems for the partner or the sleeper. This is a sign of obstructive sleeping apnea (OSA).
- Sleep disorders.Insomnia can lead to difficulty falling asleep or staying asleep, and poor quality sleep.
Nighttime signs of narcolepsy include frightening dreams and frequent awakenings, which can impact sleep quality.
- Mental health disorders.People with insomnia are more likely to experience anxiety and depression. These conditions can cause racing thoughts at night and inability to sleep well.
Your sleep quality can also be affected by other factors such as diet, exercise, travel, pains, or illnesses.
How Can You Calculate Your Sleep Quality At Home?
Start by answering some questions about your sleeping habits to calculate your home’s sleep quality.
How Long Does It Take To Fall Asleep?
Although the time taken to fall asleep can vary between individuals, a consistent 30 minute sleep duration is a sign of poor sleep quality on the Insomnia Severity Index.
How Long Are You Able To Stay In Bed?
Poor sleep efficiency is defined as a person who spends less than 85% of their day in bed.
How Many Times Do You Get Up During Sleep? For How Long?
It should take you less than 20 minutes to get back to sleep for quality sleep.
Also, you should ask questions about your day-to-day habits and waking patterns.
- Are you having trouble getting up in the mornings?
- Are you having trouble staying awake during the day or concentrating?
- Are you prone to falling asleep or do you nap a lot?
To answer these questions, it is helpful to keep a sleeping diary. You can take notes after you wake up each day and record your activities and habits before going to bed. You can use the sleep diary to identify any factors that may be affecting your sleep. The sleep diary can help you make changes to your sleeping habits, or even share your observations with your doctor.
How Do Professionals Assess Sleep Quality?
You are not the only one feeling tired. You can make your environment more conducive to sleep, have good habits during the day, and use other strategies to get better sleep.
For additional strategies to help you achieve quality sleep, see your doctor. The Pittsburgh Quality Sleep Index (PSQI) is a tool that professionals use to evaluate the quality of sleep. The PSQI, which is a set of questions that asks about sleep-related behavior, is used in clinical and research settings. The PSQI asks patients to rate their sleep quality, daytime dysfunction, and sleeping disturbances. The responses to the questions are evaluated by professionals who determine the next steps for improving patients’ quality of sleep.
If you suspect that you have a sleep disorder such as sleep apnea, narcolepsy or sleep apnea, you may need to undergo sleep tests.
One common test is polysomnography. Patients are monitored over night in a sleep lab. There are also multiple sleep latency tests that measure the patient’s ability to fall asleep, the maintenance test, and other evaluations of liver, heart and lungs.
These tests can’t measure the quality of the patient’s sleep because it is mostly subjective. These tests instead provide data and observations on the sleep and can identify any abnormalities that could be contributing to poor quality sleep.
