Many people think blue light from phones is bad for sleep. Scientists did a study in 2014. People who used iPads before bed felt more tired. But new research shows something different.
Your phone screen is not very bright. The blue light from it is very small. One day of phone light equals one minute of sunlight. Scientists say phone light does not hurt your sleep much.
What really helps sleep? Get lots of light in the morning. Go outside during the day. Turn off lights at night. The content on your phone keeps you awake more than the blue light does.
