Study links blue light from smartphones or tablets to early puberty
- h2odragon 3y agoNah, its the extra hormonal load from the early exposure to porn.
- fatfingerd 3y agoIs there a lot of rat porn?
- callalex 3y agoDo you have any links to scientific studies that found this effect?
- Jensson 3y ago10 year old girls watches porn to such a degree it affects their hormones? Obesity is the main suspect so far, but maybe it is blue light, we don't really know. But we can be pretty sure it isn't porn, since it affects young girls to such a high degree. https://www.nytimes.com/2022/05/19/science/early-puberty-medical-reason.html https://www.nytimes.com/2022/05/19/science/early-puberty-med...
- spondylosaurus 3y agoGood article (I remember reading that one when it first came out)—not only does it seem to disproportionately affect young girls, but it also seems to affect American kids more than kids from any other country.
- digging 3y agoYears ago I remember hearing it was due to growth hormones we feed livestock. Wonder if that's been debunked.
- pfdietz 3y agoI believe this is talking about a peptide hormone injected into cows. Being a peptide, if you ingest it it will be digested. It's the same reason insulin is injected, not administered orally.
- lifechoseme123 3y agoMy optometrist was quite skeptical of various claims about blue light & blue light blocking glasses, for example...
- fatfingerd 3y agoI've noticed people who start wearing blue blockers can no longer attract a mate..
- Aerbil313 3y agoMy optometrist was quite skeptical of that anyone can cure their myopia. Yet I’m doing exactly that with measured improvement.

- tabtab 3y agoIs that the ancient Chinese way of sleeping with stones on the eyes, to flatten the lenses?
- imchillyb 3y agoMyopia is the cornea slowly becoming football shaped instead of round. While the effects can be lessened through various methods, the myopia will indeed eventually overcome such methods. Can’t make a football into a soccer ball without surgery.
- Aerbil313 3y agoAhem ahem, that is the theory, yes. Not what I and many others are seeing practically. See: https://www.youtube.com/watch?v=XPIGDSY_xBs https://www.youtube.com/watch?v=XPIGDSY_xBs
- optimus_banana 3y ago"...in male rats" would be a key phrase to add to the title.
- alwayslikethis 3y agoAs an important consideration, rats are usually considered nocturnal animals. They are less active when there is light out.
- tedunangst 3y agoBut how did they teach the rats to use a tablet?
- ShakataGaNai 3y agoEvery time people talk about "Blue light" it's a problem precisely because it's like the light we get from the sun, it mucks up our circadian rhythm and keeps us awake. Or it's bad for our eyes because reasons, even though "there is no good evidence that filtering blue light with spectacles has any effect on eye health, eye strain, sleep quality or vision quality" (Wikipedia). So if tablets do the same thing the sun does and keep us awake, that must mean kids in very sunny areas have early puberty as well? Those up in the tropics with a consistently large amount of sun year round, for example? Even simple logic deduction, this story makes no sense. And when the truth comes out, it'll probably be something like "Exposing rats to the equivalent of 20 suns worth of blue light causes early puberty and death"
- Aerbil313 3y agoPuberty age in tropical regions is lower. As you near the poles, it gets higher. This is why people in higher latitudes are longer in average. Growth hormone’s release slows down when puberty is reached.
- Jensson 3y ago> are longer in average When you write this people think about genital length. I've done that mistake as well, easy to make as a non native speaker, to get the right point say "taller" not "longer".
- Lerc 3y agoIt would be interesting to see data of how much blue light an individual is exposed to proportional to their smartphone use. I would expect people who are regularly outdoors would use their smartphones less due to the difficulty of seeing the screen under the enormous blue light reaching from horizon to horizon.
