Is Blue Light Bad for Our Health?
You may know that blue light from computers, televisions, smartphones, and other electronics can contribute to migraines and eyesight. But have you heard how it’s affecting melatonin and sleep cycles?
Researchers recently tested the effects of using e-readers prior to sleep for four hours vs. reading from a traditional book for four hours before sleep each night. The study found three notable results:
😴 Exposure to e-readers caused a 10-minute delay in sleep onset vs. the control group.
😴 The experimental group spent less time in rapid eye movement (REM) sleep.
😴 There was a significant difference between groups in subjective feelings of tiredness and alertness the following morning.
Blue light at night has also been shown to suppress melatonin production. Melatonin is not just important for sleep; melatonin has also been shown to be an integral part of a healthy gut and it is also a strong antioxidant.
Many kids are also exposed to blue light from schools switching to LED lights, worsening the sleep and overall health issues.
Cyxus sent me a pair of blue-light blocking glasses for me and one for my kiddos (kid's blue light filter glasses) to check out. They come with a blue light flashlight test that you can see directly how the glasses block blue light.
👓 These glasses are inexpensive, comfortable, and effective. Obviously limiting screen time is crucial but this is a simple way to help support better health when we are in front of screens.
