Try a smartwatch or fitness tracker to monitor heart rate and sleep movements
Smartwatches and fitness trackers are a great way to monitor your sleep-wake cycle. They are easily accessible and can be purchased from a variety of retailers. These devices use a combination of heart rate monitoring and actigraphy to track and measure sleep. They can provide insights into how much time is spent in each stage of sleep. The watch will count periods of complete stillness as sleep and movements as wakefulness.
There are a variety of smartwatches and fitness trackers on the market that can help you monitor your sleep-wake cycle. Some popular options include the Apple Watch, Fitbit, Garmin, and Samsung devices. These devices collect a combination of measurements, including heart rate, heart rate variability, movement, breaths per minute, and skin temperature. They use algorithms to estimate your sleep cycles based on the data collected. For example, the Fitbit Charge 2 was found to detect sleep onset with 96% accuracy in a 2017 study.
In addition to the more popular options, there are also some lesser-known sleep trackers on the market that are worth considering. One example is the Oura Ring 4, which offers impressive battery life, a comfortable fit, and discreet design. It provides insights into sleep efficiency, restfulness, readiness, latency, and more. Another option is the Ultrahuman Ring Air, which is similar to the Oura Ring but offers subscription-free access to your wellness data.
Smartwatches and fitness trackers can be a great way to identify sleep patterns and find solutions to sleep issues. They can help you understand how much time you spend in each stage of sleep and how your body reacts as it enters each stage. This information can be used to optimize your sleep schedule and improve your overall sleep quality. These devices offer a convenient and accessible way to track your sleep-wake cycle and can be a valuable tool for anyone looking to improve their sleep habits.

Maintain a regular sleep schedule to sync your body's internal clock
Maintaining a regular sleep schedule is essential for your body's internal clock to be in sync with the day-night cycle. This is known as your circadian rhythm, and it responds to different cues that tell your body when it's time to sleep.
Your body's internal clock is influenced by the light-dark cycle, which controls the production of melatonin, the sleep hormone. When exposed to light, your brain stops producing melatonin, making you feel awake and alert. As light exposure decreases at night, your brain switches to promoting relaxation and sleep by producing more melatonin. To maintain a regular sleep schedule, it is important to plan your exposure to light. Getting exposure to light in the morning can help you wake up, while reducing exposure to light in the evening can help signal to your body that it's time to wind down.
In addition to natural light, artificial light from sources such as smartphones, laptops, and TV screens can affect your body's internal clock by providing false wakefulness cues. It is recommended to avoid screen time at least one hour before bed. Similarly, caffeine can also act as a false wakefulness cue and cause delays in your circadian clock. It is best to avoid consuming caffeine within six hours of bedtime.
Stress can also impact your sleep schedule by increasing cortisol levels, making you feel more awake. Creating a relaxing bedtime routine may help reduce stress and improve your sleep. Exercise is another important component of a healthy sleep routine, as it can help reset your internal clock. Most bodily tissues, including skeletal muscle, are linked to your biological clock.
By maintaining a consistent sleep schedule and incorporating relaxing bedtime rituals, exercise, and reduced screen time and caffeine intake, you can help sync your body's internal clock and improve your overall sleep quality.

Plan your exposure to light to help reset your internal clock
Our bodies have several internal clocks, known as circadian clocks, which follow a 24-hour repeating rhythm, or circadian rhythm. Light and darkness are among the environmental cues that help determine when we feel awake and when we feel sleepy.
Artificial light and caffeine can disrupt this process by giving your body false wakefulness cues. Spending too much time indoors can also throw off your natural circadian rhythm. The solution? Go outside and get some natural light.
Sunlight is the most important mechanism that helps sync our internal body clock with the outside world. As the days get longer in the spring, for example, the light-sensitive ipRGC cells in our eyes detect and respond to this change.
- Get outside in natural light, especially in the morning. Even if it's cloudy, 15 to 20 minutes of daylight can help recalibrate your clocks and keep them synced to the 24-hour day.
- During the day, try to get outside in little bursts, even if it's just standing near a window.
- In the evening, opt for warmer hues of light. The orangery and redder, the better. Avoid bright artificial light, which can disrupt your body's production of melatonin, making it harder to fall asleep.
- If you need to get up in the middle of the night, avoid turning on bright lights. Use a warm night light or carry a candle instead.
- If you're struggling with seasonal affective disorder (SAD) or long, dark winters, consider using light therapy lamps or red LED lights, which are less likely to impact your circadian rhythms.
- Avoid looking at bright screens before bed, as the blue light emitted from smartphones and computers can negatively affect your sleep.
- Consider using physical filters or software to filter out some of the blue light from your devices.

Avoid caffeine and artificial light before bed to prevent disrupting your sleep cycle
To log your sleep-wake cycle, you can use a combination of technology and traditional methods. Modern technology has made it easier to track sleep patterns and maximize sleep time. You can use a smartphone app, a smartwatch, or a fitness tracker to record your sleep patterns. These devices use a combination of heart rate monitoring and actigraphy to track and measure sleep.
However, to improve your sleep quality, it is essential to avoid caffeine and artificial light before bed. Caffeine, found in coffee, tea, soft drinks, and pre-workout drinks, can interfere with your sleep, especially if consumed late in the day. It can take the average person 10 to 20 minutes to fall asleep, but this time can double if you have caffeine in your system. Caffeine has a half-life of up to 4.5 hours, so it is recommended to stop consuming it by noon or at least 8 hours before bedtime. If you are sensitive to caffeine or experience insomnia, anxiety, or headaches, consider reducing your daily caffeine intake or switching to decaffeinated drinks.
Artificial light from devices like TV screens, smartphones, or bright alarm clocks can disrupt your sleep by giving your body false wakefulness cues. The light-dark cycle influences the production of melatonin, a hormone that promotes sleep, and cortisol, a hormone that prepares your body to wake up. Exposure to bright artificial light in the late evening can prevent your brain from releasing melatonin, making it harder to fall asleep. To mitigate this, you can use physical filters or software to block blue light from these devices.
In addition to avoiding caffeine and artificial light, maintaining a consistent sleep schedule, a relaxing sleep environment, and a healthy pre-bedtime routine can also contribute to improving your sleep quality.

Frequently asked questions
Your body has several internal clocks, or circadian clocks, that follow a 24-hour repeating rhythm, known as the circadian rhythm. This rhythm affects every cell, tissue, and organ in your body and how they work. Your central circadian clock, located in your brain, tells you when it is time for sleep.
There are a few ways to log your sleep/wake cycle. You can use a sleep diary to manually record when you sleep and wake up, or you can use a combination of modern technology and smartphone apps, such as the Sleep Cycle app, which uses sound analysis to track your sleep. You can also use a smartwatch or fitness tracker, which uses a combination of heart rate monitoring and actigraphy to track and measure sleep.
The light-dark cycle influences when your brain makes and releases the hormone melatonin, which promotes sleep. As you are exposed to more light, your body releases another hormone called cortisol, which naturally prepares your body to wake up. Exposure to bright artificial light in the late evening can disrupt this process and make it harder to fall asleep.
You can fix your sleep/wake cycle by planning your exposure to light, creating a bedtime routine, exercising daily, and practicing relaxation techniques.
Caffeine promotes wakefulness by blocking the receptors to adenositine, a chemical that builds up in your blood when you are awake and makes you drowsy.
