PHONES AT NIGHT REDUCES SLEEP AND CAUSES DAMAGE ON KIDS
credit
Bright light before bed reduces melatonin in children.
Children who remain exposed to bright light for an hour before going to sleep have a lower production of melatonin a hormone related to sleep consolidation and the regulation of sleep and wake cycles.

This effect is maintained at least 50 minutes after the lights go out, according to research
The study adds to an increasing number of findings suggesting that, due to structural differences in their eyes, children may be more vulnerable to the impact that light exerts on sleep and the biological clock.

Although the effects of light have been studied extensively in adults, virtually nothing is known about how exposure to night-light affects the physiology, health and development of preschool children,In this study it was found that children are extremely sensitive to light."
Less melatonin at bedtime

For the study, the researchers counted on the participation of 10 healthy children aged between 3 and 5 years. From the first to the fifth day, they fulfilled a strict schedule to normalize their body clocks and establish a pattern in the nocturnal increase of melatonin. On the sixth day, the experimenters created a dimly lit environment in the children's bedroom: they covered the windows with black plastic and changed the usual lights with low-voltage light bulbs. In this way, they made sure that everyone was exposed to the same lighting conditions. They also took saliva samples from the probands to evaluate the melatonin levels.
The following night, the children were invited to, for an hour, color drawings or play with magnetic chips on a table with a luminous surface of 1000 lux (similar to the light of a bright room). Then, they again took saliva samples to compare melatonin levels with those of the previous night. They found that they had reduced by 88 percent after exposure to bright light. The melatonin levels remained low for at least 50 minutes.

«Light is the main" timer "of our brain clock» "We know that younger individuals have larger and more crystalline pupils that are more transparent than adults. This greater sensitivity to light makes them more prone to dysregulation of sleep and the circadian clock. "
Monique LeBourgeois
when light penetrates the retina in the eye at night, it produces a cascade of signals to the circadian system to suppress melatonin which in preschoolers can not only cause problems falling asleep one night, but also chronic alterations on the break. "The effects of light on night exposure can go beyond the dream.

However, the researchers note that the sample of their study is small and that the intensity of light they used is greater than the one they emit, for example, an electronic device. In a forthcoming investigation they plan to expose 90 children to light of varying intensity to determine what light conditions affect the circadian system at these ages.

At the moment they recommend parents to dim the light in their children's bedroom in the hours before going to bed.

Now that's a comfy. Cos I keep awake late at nights with my phone.
Though I have a practice of reducing the screen brightness just for precaution.
Nice piece
Lol.. Thanks @samminator. I was also abit relieved when i saw that.. Coz i use my phone every single night
@samminator and @stevendiom note that the article says “nothing is known” as opposed to “nothing is happening” we all know how long it took to find out that tobacco was bad for us. Same could be the case here. I suggest we all dump our devices (phones, laptops, TVs etc) and go to sleep under the moonlight. At least the moon is not too bright or too dark. 😛😛😛
That's a really good article. HI, I'm new. I hope to be a good friend in the steemit :)
Thanks, @solmama, welcome to steemit..
Great article that I have personal interest in, due to being a father. I too am very bad with putting the lap-top away and my sleep suffers because of it. Although your article is very worthy and informative, it also obvious. I mean that respectfully and I just wish to point out how reliant on the mainstream flow, without questioning where it is taking us. We should all be very aware that these devices are not good at night but the software on them work directly against this principle and demand too much of our attention. The tech companies will always prefer profit over customer care so that makes your article very valuable. Our gov will also side with profit so it is up to us to highlight this information and not let people forget the dangers. You have certainly woke me up(Sorry had to throw that pun in there). Thanks. Up-voted, Re-steemed and followed.
Thanks a bunch @article61 , i really never knew how dangerous cell phones, tablets and laptops could be on kids until my siblings complained about eye ache and he sleeps less.. Now i don't allow him use any gadgets with screen lights.. I think the lights even television screens at night does more damage on kids apart from lack of sleep, which i will continue making research on.. Thanks.. Steem on and cheers..
That's a good use of your obvious wisdom. Big respect for what your doing.
Very educative
Thanks @stbrians
True, the circadian clock is disturbed by light.
A lot of us are guilty of keeping awake at night using our devices. I have an app that reduces the brightness of my phone at night too and i guess it helps a lot.
Knowing that the light has little or no effect on adult physiology is quite a relief.
Of course @rharphelle, these are little things one should take note to avoid health damage
I think it extends beyond eye damage, it affects the circadian rhythm which in turn affects your eating habits, digestion, for me I avoid phone use in bed at all costs, and I put my phone away an hour before I go to bed, and now I sleep better, my days are more productive and energetic.
This must surely be the case with adults as well. I for one am a victim of using my phone right before I go to bed. Who know me what damages I am doing to my brain😫😫
I’ve suffered with insomnia this is a great article!
