Sleep Problems
There’s another proven issue with the relatively rare blue light that our smartphone produce – our brains think it means that it’s time to stay awake since that light mimics certain aspects of daylight. Thus, using your iPhone or iPad well into the evening, and especially when using it in bed, can create insomnia and similar issues.
One of the first pieces of advice people receive when investigating sleep issues is to stop using their phones at nighttime. This may be impossible depending on your lifestyle, but at least enable the Night Shift filter and try to decrease usage before bedtime.
