Natural aging of the eyes may lead to insomnia
Results of a new study indicate that the natural aging process of the eyes may have a negative impact on how adults sleep. SeniorJournal.com reports that the yellowing of the a certain lens likely corresponds to a growing risk of insomnia.
The research, which was published in the September 1 issue of the journal Sleep, focused on 970 people who had their eyes examined to see how much blue light was being let in to the retina. This is crucial because blue light often spikes the release of melatonin, which is an important hormone in the sleeping process. Of the participants in the study, 82.8 percent reported either suffering from insomnia or using sleeping pills.
What's interesting about the findings is that the yellowing of this particular lens has little impact on vision, the website reports.
"The association between blue light lens transmission and sleep disturbances remained significant even after we corrected for age, sex, diabetes mellitus, smoking and the risk of ischemic heart disease," the study's lead author, Line Kessel, told SeniorJournal.com.
The findings could also have a much greater impact on overall health. The New York Times reports that scientists recently found that a lack of sleep may be tied to a greater risk of hypertension.
