What You'll Learn
How much deep sleep is needed
Sleep is essential to health, and deep sleep is the most important of all for feeling rested and staying healthy. While there is no minimum requirement for light sleep, deep sleep is vital for your overall health and well-being.
Deep sleep, also known as slow-wave sleep (SWS), is one of the essential phases of the sleep cycle. It is characterized by slow, high-amplitude delta brain waves on an electroencephalogram (EEG). This stage is a time when your body and mind engage in a deep restorative process. During deep sleep, the body carries out physical restoration, immune function, memory consolidation, and cognitive function. If you don't get enough deep sleep, you may be more prone to physical and mental health issues, as well as feeling sleepy during the day.
The amount of deep sleep you need can vary based on factors like age and individual differences. Adults should aim for about 10-15% of their total sleep time in deep sleep. Some people may naturally get more or less, and that’s okay. Children and teenagers tend to have more deep sleep, while as you age, the amount of deep sleep may decrease. The key is to ensure you get enough quality sleep overall, as this will naturally include the necessary deep sleep cycles.
If you’re aged 18–60 and are sleeping for 7–8 hours per night but are not waking up feeling refreshed, you may not be getting enough deep sleep. You might want to ask a doctor about doing a sleep study to help you figure out your sleep patterns. You may need treatment for a sleep disorder. On average, 25% or 105 minutes of a 7-8 hour sleep cycle is typically the deepest sleep. In which case, a total of 45 minutes is not enough deep sleep. However, sleep goes in cycles, so a person may not have 105 minutes of the deepest sleep all in one stage.
Research shows that sleeping between the hours of 8 p.m. and midnight sets you up for the best chance at restorative sleep, no matter what time your alarm is set to. Keep in mind, it typically takes about an hour to drift into these stages, so the earlier you head to bed before midnight, the better your chances of getting the hour to two hours of deep sleep typically needed.
To increase your chances of sleeping well, you can follow some tips, such as establishing regular sleep-wake habits, ensuring your sleeping space is quiet and comfortable, leaving any devices outside the room while you sleep, and establishing a bedtime routine that helps you relax before sleep.

How to get more deep sleep
Deep sleep, or slow-wave sleep, is the most restorative stage of the sleep cycle, but many people don't get enough of it. During deep sleep, the body repairs and regenerates tissues, bones, and muscles, and strengthens the immune system. It is also the stage of sleep that helps you wake up feeling refreshed.
Keep a consistent sleep schedule
Try to go to bed and wake up at the same time every day, even on weekends. This helps to regulate your body's internal clock, or circadian rhythm, and can improve the quality of your sleep.
Get morning sunlight
Exposing yourself to natural light in the morning can help reinforce your circadian rhythm and promote restorative sleep.
Avoid stimulants and screens before bed
Stimulants such as caffeine and alcohol can interfere with deep sleep cycles. It's also important to reduce screen time before bed, as the blue light emitted by electronic devices can disrupt your sleep.
Create a calming sleep environment
Keep your bedroom cool, dark, and quiet. Use blackout curtains or an eye mask to block out light, and earplugs or white noise to block out noise if necessary.
Engage in a relaxing pre-sleep routine
Signal to your body that it's time to wind down with a relaxing pre-sleep routine. This could include reading, deep breathing, or taking a warm bath.
Manage stress
Stress and anxiety can make it difficult to fall asleep and can reduce the amount of deep sleep you get. Try calming activities such as relaxation exercises, yoga, or meditation to naturally reduce anxiety and improve sleep.
Get regular physical activity
Regular physical activity during the day can help regulate your circadian rhythm and promote deeper sleep. Aim for at least 10,000 steps per day if possible.

The importance of deep sleep
Sleep is a crucial body process that allows the body to rest, repair, and restore itself. Deep sleep, in particular, is important for several reasons. Firstly, it is during the deep sleep stage that the body repairs its tissues, builds bones and muscles, and strengthens the immune system. This is especially important for babies and children, who require more deep sleep than adults. Secondly, deep sleep plays a vital role in maintaining the brain's capacity to learn efficiently. It helps restore the brain's ability to respond effectively to motor training, enabling us to adapt to new tasks and environments.
Deep sleep is also important because it is the stage when we are hardest to awaken. This is nature's way of ensuring that our bodies get the rest they need, as we are unlikely to be disturbed by external stimuli during this stage. Additionally, deep sleep is linked to feeling more refreshed and energised when we wake up. Fitbit users have reported feeling tired throughout the day if they get less than an hour of deep sleep.
To improve the quality and quantity of deep sleep, it is recommended to get sufficient physical activity and at least 10,000 steps per day. Reducing the use of electronic devices a few hours before bedtime can also positively impact deep sleep. Smart Wake on Fitbit devices can also help by avoiding waking you up during deep sleep, increasing your chances of feeling refreshed when you wake up.
In summary, deep sleep is essential for the body's repair and restoration, maintaining the brain's learning capacity, and ensuring we wake up feeling rested and energised. Getting adequate deep sleep contributes to overall health and well-being.

How does Fitbit track deep sleep
Fitbit devices use a combination of movement and heart-rate patterns to estimate sleep cycles. When you haven't moved for about an hour, your Fitbit tracker or smartwatch assumes that you're asleep. Additional data, such as the length of time of movements that are indicative of sleep behaviour (like rolling over), can also help confirm that you're asleep.
While you sleep, your device tracks the beat-to-beat changes in your heart rate, known as heart rate variability (HRV). These numbers fluctuate as you transition between light sleep, deep sleep, and REM sleep stages. When you sync your device in the morning, it uses your movement and heart rate patterns to estimate your sleep cycles from the previous night.
Fitbit's sleep researchers and the National Sleep Foundation describe the following sleep stages: Light sleep, deep sleep, and REM sleep. Light sleep serves as your entry point into sleep each night as your body unwinds and slows down. Deep sleep typically occurs earlier in the night and is characterised by less brain activity than REM sleep. REM sleep, which is associated with vivid dreams, typically occurs in longer periods during the second half of the night.
Fitbit devices with heart-rate tracking capabilities can record the sleep stages you cycle through. Fitbit's sleep staging is correct in 30-second blocks slightly more than two-thirds of the time. Over time, you can gain insights into your sleep patterns and identify when you need more rest.

The meaning of deep sleep
Sleep is an essential component of health, and its timing, duration, and quality are critical determinants of a person's overall health, affecting metabolic and emotional regulation, performance, and memory. The Fitbit device helps you track your sleep and understand your sleep patterns better.
Deep sleep is a part of the non-rapid eye movement (NREM) sleep stage, which also includes light sleep. During this stage, your brain exhibits less activity than in the REM sleep stage. Periods of deep sleep are typically longer earlier in the night.
Deep sleep varies by age and sex. The amount of deep sleep one should get depends on the individual, with some people feeling okay with 30-40 minutes of deep sleep, while others require an hour or more. Getting enough physical activity and at least 10,000 steps in a day can help increase the duration of deep sleep. Disconnecting from electronic devices a few hours before bed may also improve the quality and duration of deep sleep.
Fitbit devices with heart-rate tracking can monitor your sleep by tracking beat-to-beat changes in your heart rate and movement patterns. The Fitbit Sleep Score is a quick way to gauge your sleep, taking into account heart rate, time spent awake or restless, and sleep stages. The overall sleep score is based on sleep duration, sleep quality, and restoration, with a maximum score of 100.
