Researchers at Oregon State University published a study that says blue light affect longevity when used for extended periods of time. The study used fruit flies, who share similar cellular mechanisms with humans, to observe long-term effects of blue light exposure. They found that those exposed to 12 hours of the blue light have shorter life spans than the control group, implying that the light accelerates aging at the cellular level. While natural light is crucial to maintaining circadian rhythms, artificial light can interfere with brain wave activity and cell regeneration. As people use devices with blue light at increasing rates, experts suggest using amber-tinted glasses or using orange light features can help.
