हर बात की तरह कह रहा हूँ – निद्रा एक अत्यंत आवश्यक पवित्र कर्मकांड है ! उपेक्षा कर अपना और परिवार का जीवन दांव पर न लगाओ ।
रतिभार सा कृत्रिम प्रकाश भी बच्चों के लिए अच्छा नहीं । बच्चों के शरीर को वयस्क शरीर न समझो ! हम से अधिक हानि उनको है !
The carelessness about post-sunset artificial light setup is one silent but critical aspect of health.
I have been calling LED lights as IED (programmed bombs) and was vocal against Govt policies to subsidize it.
Forget before sleep, even after kids are slept, parents keep the room lighting on for their own work. And this affect the kids severely as per this research.
As I always suggest – Sleeping is most sacred ritual. Don’t be ignorant and careless about it. No gadgets before 2 hrs. Dim focused yellow light for reading if you wish. And absolutely no light during sleep!
Even slight exposure to light can prompt the critical sleep-promoting hormone melatonin to plummet in preschoolers in the hour before bedtime, potentially disrupting slumber long after the light goes out, according to new CU Boulder research.
Light: The body’s strongest time cue
Light is the body’s primary time cue, influencing circadian rhythms that regulate everything from when we feel tired or hungry to what our body temperature is throughout the day.
When light hits the retina, a signal transmits to a part of the brain called the suprachiasmatic nucleus, which coordinates rhythms throughout the body, including nightly production of melatonin. If this exposure happens in the evening as melatonin is naturally increasing, it can slow or halt it, delaying the body’s ability to transition into biological nighttime.
Because children’s eyes have larger pupils and more transparent lenses than adults, light streams into them more freely. (One recent study showed that the transmission of blue light through a 9-year-old’s eye is 1.2-times higher than that of an adult.)
“Kids are not just little adults,” said senior author Monique LeBourgeois, an associate professor of Integrative Physiology and one of the few researchers in the world to study the circadian biology of young children. “This heightened sensitivity to light may make them even more susceptible to dysregulation of sleep and the circadian system.”
