Researchers say that blue light always flows out of the smartphone. Due to that, the activities of the smartphone are clearly visible in the light of the sun. These kinds of lighting emanate from laptops, TVs, and so on.
Researchers say that the light on this smartphone has actually been made to imitate the light of the sun. Your brain has been created in such a way that as long as the sun's light is there, there will be a hormone called melatonin so that your sleep will be inconvenient.
Because of the light of the sun's light and the smartphone, this light confuses your brain when you run a smartphone at night. The brain begins to think about melatonin, which is why you do not sleep or sleep well at night.
Experts advised that the use of any electrical device should be stopped three hours before sleeping. The melatonin emits from the pineal gland of the brain. Blue light is considered as the main cause of insomnia. So experts have blamed light sensitivity, which is called Melanopsin. This melanopsin is found in the cell that is available to communicate with the retinal nerve, which actually becomes active in blue light.
