Subha ka alarm miss hojata hai chahe kitni dafa time set karo?

If you can’t wake up in the morning, you’re not alone. And now you have a scientific explanation that is more respectable than good old laziness.
Researchers have concluded that there is a logical explanation behind why you can’t seem to become a morning person- and it all boils down to the way genes function, as Wired has reported.

Previous research done by a group of biologists who later went on to win the Noble Prize in 2017 showed that human bodies have a total of 24 genes known as the ‘period genes’ which determine the human body clock.

Now, research published by New Communications has concluded that there are actually 351 genes, which can determine whether a person is an early bird or a night owl. According to Michael Weedon, a bioinformatics at the University of Exeter Medical School:

“Depending on how many of those genes you carry, you can be anywhere on the scale of ‘morningness’. But our research showed that the top five per cent with the most of those 351 genes go to sleep on average 25 minutes earlier than the five per cent who carry the least.”

Furthermore, the study further looked into where those genes are more likely to be switched on in the body, because different parts of our body carry different tissues. Samuel Jones from the University of Exeter Medical School explained:

“The genes we found to be related to our circadian rhythms tend to be switched on a lot more in the brain and in the retina,” he explained. “This helps us map what parts of the body are important in creating morning and evening people.”

The scientists went on to explain how the genes are activated inside our brain. In a specific zone of the hypothalamus known as suprachiasmatic nucleus (SNC), an oscillator which sets our body time of the day, in accordance to the diffferent signals it receives from the environment.

An important signal for the SNC to activate is light, because once the retina signals that it is night time, our brain releases a sleep-inducing hormone called melatonin, which is our cue to fall asleep.
