How to Use a Blue Light Blocker on Your MacBook

Are you having trouble sleeping due to excessive screen time in the evening? If so, you're not alone. Exposure to blue light emitted by screens can confuse our body and reduce the production of melatonin, the hormone responsible for triggering sleep. Fortunately, Apple has made it easy to filter out this blue light on your MacBook with its built-in feature called Night Shift.

To activate Night Shift on your MacBook, go to System Preferences > Displays > Night Shift. This will schedule the feature to turn on at a specific time of day or until the next morning. You can also adjust the color temperature of your screen to reduce the negative impact of screens on sleep quality.

But what about iPhones and iPads? The process is similar. To activate the blue light filter on your iOS device, go to Settings > Display & Brightness > Night Shift. This feature is available for devices running iOS version 9.3 or newer (iPhone 5s or iPad 2).

While these apps will help you get better sleep, it's still important to avoid screens before bedtime. Screens emit a blueish light similar to sunlight at noon, which can disrupt our body's natural sleep cycle. For most of human history, our sleep has been guided by the sunlight.

So, what can you do? Start by turning off your devices at least an hour before bedtime and finding a relaxing activity to wind down. You can also try using blue light filtering glasses or apps that don't rely on Apple's Night Shift feature.

In conclusion, using a blue light blocker on your MacBook or iOS device is a simple way to improve the quality of your sleep. By reducing exposure to blue light in the evening, you'll be better equipped to get the restful night's sleep you need.
