Yes, artificial blue light is present in your phone's screen.
Understanding Blue Light from Phones
Your phone screen emits artificial blue light. This is different from the natural blue light from the sun, although both types of light affect our bodies similarly. The reference material clearly states that: "Artificial blue light is found in digital devices such as smartphones and computers". The artificial blue light from your phone's screen contributes to the overall amount of blue light exposure you receive daily.
How Blue Light Affects You
While natural blue light helps regulate your sleep-wake cycle by influencing melatonin production, excessive exposure to artificial blue light from devices like your phone can disrupt this cycle. This disruption can lead to difficulty falling asleep or staying asleep. It's important to be mindful of your screen time, especially before bed.
Minimizing Blue Light Exposure
Several options exist to reduce blue light exposure from your phone:
- Reduce screen time: Limit your phone usage, especially in the hours leading up to sleep.
- Use blue light filter: Many phones offer built-in blue light filter settings or "night mode" that reduce blue light emission.
- Install apps: Third-party apps provide more advanced blue light filtering capabilities.
