Hey, night owls, good news!
If you are not an early-to-bed-early-to-rise person, it could because it is biologically impossible for your brain.
A new study posted on Newsmax, points to a study showing that whether you're an early bird or a night owl is a decision made by your genes.
But don't worry, night owls! Evolutionary Biologist Suzanne Sadedin says night owls are better at reasoning, more productive, wealthier, and more professionally successful.
And, Sadedin says, your genes aren't the only thing determining whether you're an early riser or an all-nighter.
Artificial light in the evening from things such as lamps or computer or mobile device screens could also be to blame.
Sadedin shares her answer with Quora. "Here’s how it works. Your eyes contain special photosensitive cells (in addition to the rods and cones you use for normal vision) which reach back into your hypothalamus. When light touches your eyes, these cells alert the hypothalamus, which uses the information to decide whether it’s daytime based on a roughly 24-hour cycle. When your hypothalamus decides it’s night time, it tells your pineal gland to secrete melatonin. And melatonin makes you sleepy," explains Sadedin. "Artificial lighting at night confuses your hypothalamus. It thinks, oops, I’m out by a couple of hours. So it tries to correct by making you sleep longer in the morning. People also often shut out morning light with curtains, confusing their hypothalami even more. That night, your hypothalamus sticks to its new schedule, so you get sleepy later, so you keep the lights on later, and your hypothalamus decides to shift your cycle even further."
Thus, the night owl cycle continues.
Sadedin also states that our internal circadian clock is something we don't want to mess with. While we sleep, it's responsible for lowering our core body temperature and stress hormones, as well as decreasing our heart rate.
In fact, when the circadian clock is off kilter, Sadedin says it affects the ability of more than 1500 genes.
If your genes labeled you a night owl, there's not much you can do to change it, however, you can help get your sleep and circadian clock back on track by simply eliminating nighttime artificial light - a tough habit to break in this high-tech world.
