This is the main reason why you wake up before your alarm clock.

You've certainly had the experience of waking up before the alarm clock, the seemingly precious ten or fifteen minutes that herald the time to get out of bed to announce the day's activities.

The reasons that lead a person to wake up before the alarm clock are related to the biological clock and the increase in the level of a certain protein in the body's cells.

Understand the relationship between waking up before the alarm clock and the biological clock

The circadian cycle concerns the set of changes experienced by our body in a 24-hour period. Hunger, sleep, agitation and drowsiness are explained by the circadian cycle.

Helping to control the circadian rhythm is the biological clock, which works through the interaction of proteins present in cells and the suprachiasmatic nucleus (SCN), a set of nerves present in the central region of the brain.

Throughout the day, the SCN is in control of different bodily functions such as blood pressure regulation, digestion, body temperature and hormone release. However, in addition to these physical phenomena, the SQN also interferes with the perception of time experienced by human beings.

In this sense, the reason why you wake up before the alarm clock is related to SNQ activity and the regulation of the biological clock. As? From the performance of two proteins known as PER and TIM.

The PER and TIM proteins are responsible for regulating sleep cycles and waking periods. During the night, these proteins accumulate in the inner region of the cells and decrease throughout the day.

That way, when you start to feel drowsy, it means your PER levels are low and it's time for bed. However, for those who usually go to bed and wake up at the same time, your body will understand when to increase PER protein levels, responsible for waking you up.

In this way, even during sleep, your brain continues to work, not only levels are increased. of PER before the alarm clock, but of cortisol, a fundamental stress hormone to start the activities of the day.

Therefore, as PER levels increase, your body starts to wake up slowly to avoid surprise and shock before the alarm starts to sound. It's a subtle way to wake you up. So every time you open your eyes before the alarm clock starts ringing, remember that your PER levels are high and it's time to get up!
