Sleep scores are a way of measuring the quality and quantity of your sleep. They are calculated using metrics such as sleep stages, restfulness, timing, sleep efficiency, and latency. Sleep scores typically range from 0-100, with scores of 85 or above considered optimal, and scores below 70 indicating that you may need to prioritise rest and recovery. A score of 70 suggests that your sleep is off-balance and that there may be lifestyle changes you can make to improve it. Sleep scores are designed to give you a holistic perspective on your sleep patterns and help you identify areas where you can make adjustments to meet your goals.

What You'll Learn
A score of 70 indicates a need for lifestyle changes
A sleep score of 70 or below indicates that you need to make some lifestyle changes. A good night's sleep is essential for overall health and well-being, and there are several factors that contribute to the quality of sleep. Firstly, it is important to understand the different stages of sleep, including Awake Time, Light Sleep, Deep Sleep, and REM Sleep. REM sleep, which is associated with dreaming, memory consolidation, and creativity, typically accounts for 20-25% of total sleep time for adults and decreases with age. On the other hand, deep sleep is the most restorative and rejuvenating sleep stage, making up 0-35% of total sleep.
To improve your sleep score, it is recommended to prioritize rest and recovery. This can be achieved by maintaining a consistent sleep schedule, aiming for 7-9 hours of total sleep per night, and creating a buffer by allowing for an 8-10 hour window between bedtime and wake-up time. This buffer accounts for factors such as falling asleep, brief disturbances, and awake time, ensuring that you get the recommended amount of sleep. Additionally, maintaining a consistent sleep schedule helps anchor your sleep, improving both its quantity and quality.
Another important aspect of improving your sleep score is limiting certain activities and substances before bed. Strenuous exercise, heavy meals, and alcohol consumption should be avoided within a few hours of bedtime. Sugar intake in the evening can also lead to more wake-ups during the night and less deep sleep, as it raises your metabolic rate and average body temperature. Caffeine intake should also be limited, especially after 2 pm, as it can impact your ability to fall asleep and maintain deep sleep.
It is also crucial to consider the impact of electronic devices on your sleep. Blue light emitted by screens can suppress melatonin production, affecting your sleep quality. Therefore, it is recommended to cut off screen time and artificial light at least an hour before bed. If you need to use electronic devices, consider using blue light glasses to reduce stimulation. Additionally, limit your phone usage at night, as it can activate your mind, cause stress, and expose you to harmful blue light.
By making these lifestyle changes and prioritizing rest, you can work towards improving your sleep score and, consequently, your overall health and well-being.

Sleep scores reflect sleep quality and quantity
Sleep scores are calculated using multiple contributors, including total sleep time, sleep efficiency, and latency (the time it takes to fall asleep). The more restful your sleep, the higher your score. Restful sleep is indicated by green, while restless sleep is indicated by yellow. Sleep scores also take into account factors such as your average body temperature, movement, and time spent in specific sleep stages, including light sleep, deep sleep, and REM sleep. REM sleep is associated with dreaming, memory consolidation, and creativity, and it decreases with age. On average, REM sleep accounts for 20-25% of total sleep time for adults, and a REM sleep total of 90 minutes or more will result in an optimal sleep score.
To improve your sleep score, it is recommended to cut off screen time and artificial light at least an hour before bed, as blue light emitted by screens can impact your sleep quality. Instead, dim or turn off the lights in your home or bedroom. In the morning, try to get some natural light as soon as possible to support your circadian rhythm, which regulates your sleep and wake patterns. Additionally, limit caffeine after 2 pm, strenuous exercise, heavy meals, and alcohol consumption a few hours before bed, as these can disrupt your sleep.
While a sleep score of 70 or below suggests areas for improvement, it's important to interpret your score based on how you feel. If you're feeling refreshed and energised in the morning, your score may be a good indication of your sleep quality and quantity, even if it falls below 70. Sleep scores are meant to provide guidance and help you understand your sleep patterns so that you can make adjustments as needed to achieve optimal rest.

Scores are calculated using sleep time, efficiency, and latency
Sleep scores are calculated using sleep time, efficiency, and latency, and they reflect the quality and quantity of your sleep. A sleep score of 70 or below indicates that your sleep is off-balance and that you may need to make some lifestyle changes.
Sleep time is the amount of time spent in bed sleeping. This is different from time in bed, which is the duration of time from when you get into bed to when you get out of bed in the morning. Dividing your sleep time by your time in bed gives you your sleep efficiency. Sleep efficiency is the percentage of time spent asleep during the night. For adults, an efficiency of 85% is considered optimal.
Latency refers to the amount of time it takes you to fall asleep. This is one of the key factors that contribute to your sleep score. The quicker you fall asleep, the higher your sleep score will be.
Sleep scores are also influenced by sleep stages, including awake time, light sleep, deep sleep, and REM sleep. REM sleep is associated with dreaming, memory consolidation, and creativity. It accounts for 20-25% of total sleep time for adults, and a REM sleep total of 90 minutes or more will result in a higher sleep score. Deep sleep, on the other hand, is the most restorative and rejuvenating sleep stage. It can make up anywhere from 0-35% of your total sleep, and the recommended duration varies with age.
To improve your sleep score, it is important to maintain a consistent sleep schedule and limit distractions before bed. This includes reducing screen time and exposure to blue light, which can suppress the production of melatonin and disrupt your sleep.

Sleep quality is impacted by screen time and artificial light
A sleep score of 70 or below indicates that your sleep is off-balance and that you may need to make some lifestyle changes to improve it. Sleep quality is impacted by screen time and artificial light, and these factors can contribute to a lower sleep score.
Excessive screen time before bed can negatively affect sleep quality and disrupt the natural sleep-wake cycle, known as the circadian rhythm. Blue light emitted from electronic devices such as smartphones, tablets, and computers can cause increased alertness and delay the production of melatonin, a hormone that induces sleepiness. This disruption to the natural release of melatonin can make it harder to fall asleep and impact the overall quality of rest.
Studies have shown that engaging in stimulating activities on electronic devices, such as texting, playing video games, or watching exciting or violent content, can increase heart rate and make it even more challenging to fall asleep. The mental stimulation and stress induced by digital engagement before bedtime can further impair sleep quality. Additionally, the bright light from screens can disrupt sleep by causing alertness and delaying the transition to sleep, even if individuals are engaged in soothing online activities.
To improve sleep quality and potentially increase your sleep score, it is recommended to cut off screen time at least an hour before bed. Reducing exposure to blue light by dimming the screen brightness or using blue-light filtering settings or glasses can also help mitigate the negative impacts of screen time on sleep. Creating a bedtime routine that minimizes screen time and promotes a calm environment can aid in improving sleep quality and overall well-being.
In addition to limiting screen time, maintaining a consistent sleep schedule is crucial for optimizing sleep quality. Going to bed and waking up at the same time every day, including weekends, helps anchor your sleep and improves both its quantity and quality. This regularity supports your circadian rhythm, making it easier for your body to rest and recharge effectively.
