Apple implementing sleep-friendly 'Night Shift' mode in MacOS Sierra 10.12.4

Apple has always been at the forefront of technological innovation, and their latest feature is no exception. In the latest update to MacOS Sierra, version 10.12.4, Apple has implemented a sleep-friendly 'Night Shift' mode. This new feature aims to improve the quality of your sleep by reducing the amount of blue light emitted by your computer screen during the evening hours.

You may be wondering, what is blue light and why is it a problem? Blue light is a type of light that is emitted by electronic devices such as smartphones, tablets, and computer screens. It has a short wavelength and a high energy level, which means it can interfere with your sleep patterns.

Research has shown that exposure to blue light in the evening can suppress the production of melatonin, a hormone that regulates your sleep-wake cycle. This can lead to difficulty falling asleep and poor quality sleep overall. In fact, studies have indicated that exposure to blue light before bedtime can delay the onset of sleep by up to an hour.

This is where Apple's Night Shift mode comes in. When you enable Night Shift, your computer screen will automatically adjust its color temperature based on the time of day. During the evening hours, the screen will emit warmer tones that are easier on the eyes and less disruptive to your sleep patterns. Then, in the morning, it will gradually shift back to its regular display.

The benefits of Night Shift mode are not just theoretical. Several studies have demonstrated its effectiveness in improving sleep quality. A study published in the journal Sleep Health found that participants who used Night Shift on their iPhones reported better sleep quality and increased satisfaction with their sleep. Another study conducted by the Lighting Research Center at Rensselaer Polytechnic Institute revealed that exposure to warmer light in the evening can lead to earlier sleep onset and increased alertness in the morning.

Enabling Night Shift mode on your MacOS Sierra 10.12.4 is simple. Just go to the Display section in System Preferences and click on the Night Shift tab. From there, you can choose to have Night Shift automatically turn on and off based on the time of day, or you can manually enable it whenever you want.

It's important to note that Night Shift mode is not a complete solution to getting a good night's sleep. Other factors, such as your sleeping environment and bedtime routine, also play a significant role. However, by reducing your exposure to blue light in the evening, Night Shift can be a valuable tool in improving your sleep quality.

So, if you're someone who spends a lot of time in front of your computer screen, particularly in the evening, Apple's Night Shift mode is definitely worth a try. It's a small but impactful change that can make a big difference in your sleep patterns. Give it a go and see how it improves your sleep.

How is its design?

The design of Apple's sleep-friendly 'Night Shift' mode in MacOS Sierra 10.12.4 aims to promote better sleep quality by reducing blue light exposure from computer screens. This feature automatically adjusts the color temperature of your display to a warmer and more sleep-friendly tone as the evening approaches.

By shifting the display towards warmer colors, Night Shift helps to align your screen's light with the natural lighting conditions of your surroundings. Exposure to blue light in the evening can disrupt our circadian rhythm, making it harder to fall asleep. With Night Shift, Apple aims to mitigate this issue and promote a more restful sleep.

To activate Night Shift, you can simply go to the Display tab within the System Preferences panel on your Mac. From there, you can schedule Night Shift to turn on and off automatically at specific times or adjust the color temperature manually to your preference. The intensity of the shift can be adjusted using a slider, allowing for customization based on individual preferences.

It's important to note that while Night Shift can help reduce blue light exposure, it's not a magical solution to all sleep-related issues. Maintaining a consistent sleep schedule, practicing good sleep hygiene, and creating a dark and calming sleep environment are also essential for a restful night's sleep.

The introduction of Night Shift on MacOS Sierra demonstrates Apple's commitment to providing users with tools that positively impact their well-being. With this feature, Apple recognizes the importance of sleep and aims to offer a sleep-friendly experience for their users, ensuring that they are able to work efficiently without compromising their rest.

How is its performance?

The implementation of the sleep-friendly 'Night Shift' mode in MacOS Sierra 10.12.4 by Apple has received positive feedback from users. It offers a variety of benefits for those who work late or use their devices at night.

'Night Shift' mode adjusts the color temperature of your Mac's display to reduce the amount of blue light emitted. This helps to provide a warmer and more sleep-friendly environment, particularly in the evening or at night when bright blue light can disrupt your sleep patterns.

With 'Night Shift', you no longer need to rely on third-party apps or external software to achieve a sleep-friendly display. Apple has recognized the importance of user-friendly features that enhance the overall experience.

The introduction of this feature in MacOS Sierra 10.12.4 has been well-received due to its ease of use. You can easily enable or schedule 'Night Shift' from the Display settings in System Preferences. It allows you to choose the desired color temperature and the schedule you prefer, making it highly customizable to fit your needs.

Research has shown that exposure to blue light in the evening suppresses the production of melatonin, a hormone that regulates sleep. By reducing the amount of blue light emitted from your Mac's display, 'Night Shift' helps to promote healthier sleep patterns.

While the performance of 'Night Shift' in MacOS Sierra 10.12.4 is generally smooth and reliable, it's worth noting that using this feature may have a minimal impact on battery life. However, this shouldn't be a significant concern for most users.

Overall, the addition of 'Night Shift' mode in MacOS Sierra 10.12.4 demonstrates Apple's dedication to enhancing the user experience by providing a built-in solution for reducing blue light exposure. By prioritizing sleep-friendly features, Apple acknowledges the importance of promoting healthy habits and addressing the needs of its users.

What are the models?

Night Shift mode in MacOS Sierra 10.12.4 is available on various models of Apple computers. If you own a MacBook Air, MacBook Pro, iMac, Mac mini, or Mac Pro from 2012 or later, you can take advantage of this sleep-friendly feature. Night Shift mode adjusts the color temperature of your display as the day progresses, reducing the amount of blue light emitted in the evenings. This can help improve your sleep quality by making it easier for your eyes to adjust to the surrounding light. With Night Shift mode, you can enjoy using your Mac even during nighttime hours without the usual strain on your eyes. So, if you have one of the compatible Apple models, make sure to update your MacOS to version 10.12.4 or newer and enable Night Shift for a more sleep-friendly experience.


In conclusion, the implementation of the sleep-friendly 'Night Shift' mode in MacOS Sierra 10.12.4 is a valuable addition for Apple users.

With Night Shift, the warmer, more subdued display tones make it easier for your eyes to relax, ultimately aiding in a smoother transition to sleep.

Studies have shown that exposure to blue light in the evening can suppress the production of the sleep hormone melatonin, making it harder to fall asleep and potentially leading to disrupted sleep patterns.
