There are people who need a lot of help to get up, while others manage to do it independently. I found out why it happens.

The alarm clock is the great ally to start with the routines. Most people use it as a tool to start the day, while others say that “they don’t need it”. Although the causes are not entirely clear, there are clear reasons: the answer is in our internal clockan element regulated by the brain. All people have an internal clock that is the one that governs our chronobiology, which are the times of our organism.

And it is that this “biological clock” is the one that marks us when to be smart and activeor even when we have to sleepy and go to sleep.

The “biological clock”: what it is and how it is regulated

Our internal clock is regulated, mainly, by the light. our core “suprachiasmatic”which is the main center for regulating the so-called circadian rhythm in the brain, is the one that measures is it time to sleep or is it time to be active. In addition to light, there are other stimuli such as meal times. If we have regular hours, that information it is extremely influential for our internal clock.

With that information, this watch it synchronizes and there comes a time when, if in addition we have a very regular schedule to go to bed and get up every day at the same time, our clock will also know when do we have to wake upeven though we may be sleeping.

It also happens that, if we are very used to getting up at a certain time for long periods of time, the weekend can come and we end up waking up When ever, even without an alarm clock. That’s because our brain handle that information.

Hormones that act on the body’s biological clock

The factors that regulate the internal clock activate a series of hormonesas are for example the cortisol wave melatonin. Those hormones are the ones that measure if we are hustlers Or if we are sleepy. Another aspect to take into account It is the sensitivity of each person. There are people who may have very sensitive to lightso waking up without an alarm can happen to them very easily, while others that have much less sensitivity will never happen to them.
