Flashing lights can have a number of effects on the brain, including lowered intelligence and reduced memory. While they are a common component of many LED lights, these lights can have negative effects on the brain due to their short-lived lightening bolts.
One study found that those who had the most flashing lights in their environment had the most raised blood pressure. When their blood pressure was measured before the lightening bolts, those with the highest blood pressurestrain had the worst overall brain function.
So, when you are flashing your light at work or school, be sure to keep your eyes wide open for a few minutes each day to get the most out of these rays of light!
