FromEffects of sleeping lateand long nights awake, how much do you know?
Have you ever forgotten to set your alarm and wake up on time? This is not magic; it’s biology. Most living creatures, like fungi and plants, have a biological clock.

This clock is very accurate and is located in our brain, managed by the hypothalamus – exactly the part of the brain that connects the eyes to the brain. Our brain’s clock uses light to regulate the body’s daily cycle. This cycle is scientifically known as the circadian rhythm and informs us about the times to wake up, rest, eat, and drink.
It’s true that we all have this cycle, but that doesn’t mean it’s the same for everyone. In different individuals, this clock is set differently, meaning they have different body times. These different settings are called chronotypes and are not related to our preferences. In other words, people who prefer to sleep late at night and wake up late in the morning will experience exactly that because their biological clock is set this way.
But if you listen to your body’s clock and act accordingly, will it benefit you?
The problem is that many night owls try to behave according to their body’s circadian rhythm and become early risers. For example, they wake up with the light of day, go to work early, and finish their tasks, aiming for maximum productivity before heading home to stay awake until 2 AM.
This cycle can certainly be the most ideal situation. Therefore, in this section of healthSelMagzwe introduce the effects of sleeping late at night, which will certainly be helpful.
