  • Yes, as it impacts the melatonin and hormonal levels
  • Maybe, since it disturbs the circadian rhythm
  • No, blue light cannot affect puberty directly

      A new study stated some intriguing discoveries concerning smartphones and their implications on children’s health. According to a mice study presented at the 60th Annual European Society for Pediatric Endocrinology Conference, constant exposure to blue light from tablets and smartphones may disrupt hormone levels and increase the risk of early puberty.

      Blue light is believed to interfere with our biological clock by slowing the rise in melatonin levels in the evenings to prepare our bodies for sleep and rest. According to the paper, pre-puberty has greater melatonin levels than puberty, which may contribute to the delayed onset of puberty. The delicate process of puberty needs the synchronization of multiple biological processes and hormones.

      The mice exposed to blue light experienced structural alterations in their ovarian tissue, reduced melatonin levels, and increased levels of two specific reproductive hormones (luteinizing hormone and oestradiol). These variations are associated with the onset of puberty. The longer the duration of exposure, the sooner puberty begins, with additional risks for prenatal development and future fertility.

      Possibly, but also look at the link to increased adiposity caused by a sedentary lifestyle causing global endocrine dysregulation, and the increased aromatase activity in fat cells converting testosterone to estrogen.

      Yes cellphones, blue light emission have been linked to various ill health effects in the past. Due to pandemic and online school, younger generation have been more compelled to use devices often. Hypothesis of blue light is also associated with aging.
