Scientists at Flinders University in Australia have discovered that sleep disturbances may be a harmful side effect of myopia in children. Research results published In Sleep magazine.
The study examined differences in the timing of melatonin (the so-called sleep hormone), sleep characteristics, and cognitive functions in 26 myopic and 14 non-myopic children between the ages of 8 and 15. Good sleep is said to be beneficial for a baby’s eye development, and daylight exposure is said to be associated with the production of melatonin, dopamine, and other regulators that help regulate circadian rhythms.
The results showed that myopic children had reduced melatonin production at night. As a result, they were more likely to experience circadian rhythm disorders (difficulty falling asleep and waking up on time). In addition, children with myopia showed decreased sleep quality, as evidenced by frequent awakenings during the night.
According to the researchers, their discovery could further contribute to the development of new and effective treatments for insomnia. Scientists have also suggested that exposure to sunlight while playing outside may improve children’s sleep.
