We’re all locked in. We need to use our computers for work, we interact with one another via social media, and most of our entertainment lives on a digital screen. Our digitally addicted lifestyle isn’t going anywhere soon. And that’s okay. We just need to become more aware of the light we consume and how it impacts our health.
Research has shown that exposure to certain wavelengths can have both positive and negative effects on the body. Proper lighting can increase health and productivity, while over exposure to blue light (as well as under exposure) can alter mood, suppress the immune system, and even raise the potential for disease.
One concern is that the disruption of the circadian rhythm can have effects that are much more widespread than getting a good night’s sleep. Exposure to blue light signals the hypothalamus to produce certain neuro-hormones.
Dr. Joan Roberts, a professor at Fordham University in New York, writes the following:
“Proper blue visible light in the morning and lack of circadian blue light in the evening modulates the sleep/wake cycle, growth, blood pressure, reproduction, stress, and metabolism. If the body’s circadian rhythm is balanced, there is maximum morning alertness and productivity, and deep (delta) restorative sleep in the evening. If circadian rhythm is disrupted, this can lead to behavioral problems such as depression, agitation…”
Dr. Roberts proposes the solution of being conscious of the light you are consuming and increasing exposure to natural light from 6:00am-9:00am and filtering out blue light from screens and artificial lights. She suggests that after 10:00pm blue light should be as close to eliminated as possible.
Our smartphone, tablet, and TV emit lots of blue light. When we consume this light in the evening, our body doesn’t realize the sun has gone down; our circadian rhythm is disrupted. PupilBox is bringing a number of solutions to market to help us moderate our blue light consumption and allow us to stay digitally addicted.
