How Blue Light Impacts Your Sleep

Preheader


Thanks to blue light, your eyes send a message to your brain that the sun is still shining, even if it already set long ago. This is okay during the middle of the day when you are trying to stay alert, but it prevents melatonin production at night when you should be winding down for bed.

Limiting Blue Light Exposure

By reducing blue light when your body is trying to wind down, you can help resume your natural circadian rhythm. Try out these tips:
Limiting blue light from your screens
Apple iOS (Night Shift) and Android (Night Light) allow you to schedule and control the amount of blue light your device emits. Similar applications can be found on computers.

Blue light-blocking glasses
These are a great complementary tool to other blue-light-blocking technologies.

Room lighting
Special light bulbs can reduce or eliminate blue light as well, ensuring your bedroom adheres to your body's schedule.

Discovering What Works For You With Oura

Start with one of the above hacks and you may find yourself falling asleep faster or boosting the amount of deep sleep you get each night. Oura can help by tracking:

Nightly Heart Rate Trend

Your Oura resting heart rate (RHR) curve can help you see the effects of late meals, evening workouts, alcohol, sickness, or being misaligned with your body’s ideal sleep window.


Sleep Stages

All stages of sleep are important and your body naturally regulates your sleep cycles to make sure you get what you need. You can see your daily sleep patterns in the Oura app.


Sleep Score
In addition to RHR, Oura tracks heart rate variability (HRV), body temperature, respiratory rate, and movement, to determine your sleep patterns every night, giving you actionable insights when you wake up.
