Biological clockA clock is a device that allows you to perform a measurement of the weather. Biological, for its part, is that which is linked to biology (the science that studies the characteristics and properties of living organisms).

It is called biological clock to the internal mechanism of a living being that allows you to have a temporal orientation. It is not, of course, a machine that displays the hours and minutes, but a set of organic functions linked to the rhythm of life.

The biological clock causes that, when it approaches noon, we begin to feel hungry since it anticipates us that it will be time to have lunch. The same thing happens at nightfall, when we begin to have sleep.

What the biological clock does is temporarily order various organic activities. This order implies the development of cycles (which make us hungry or sleepy every few hours, for example). Glandular secretions, regulation of the temperature of the body and even the functioning of the heart and brain, among other organs, depend on the biological clock.

Various decisions and activities that we develop can cause changes in the biological clock, generating various kinds of imbalances. People who do not maintain a regular schedule to eat or those who live at night and sleep during the day experience various inconveniences due to altering their biological clock: chronic fatigue, lack of appetite, depression, etc.

To regulate the biological clock, the ideal is to maintain a daily routine regarding rest, physical activity and food. This helps optimize the operation of the organism.

According to the studies of certain experts, the lack of hours of sleep can even collaborate with diseases such as cancer, type II diabetes, obesity, heart complications, and various infections. Although it is not possible to create a universal table to know the functioning of the organism at every hour, there are approximations of some validity that serve to learn a little more about our biological clock.

Let’s see some of the state changes that humans usually experience throughout a full day:

Biological clock* between 6 and 8:59 am: this period is the ideal time to get out of bed. For men it is the point at which their testosterone reaches the level maximum. On the other hand, it is the moment in which the heart is most exposed to stops, since its vessels present greater rigidity and less flexibility with respect to the rest of the day, blood pressure is at its highest peak and blood it is very thick;

* between 9 a.m. and 11:59 a.m.: in this range our short-term memory works better than ever, and our brain is capable of processing information with special intensity. This receives a particular stimulus of attention, since cortisol (the stress hormone) is at its peak;

* between 12 noon and 2:59 pm: it is normal to eat in this portion of the day, which is why gastric activity increases, alert levels drop and, according to statistics, the highest percentage of traffic accidents takes place;

* between 3 and 5:59 pm: the temperature internal reaches its peak, the heart and lungs work better than the rest of the day, and it is an ideal time for physical activities, such as exercise;

* between 6 and 8:59 pm: It is the ideal time for dinner, although it is not advisable to overdo it, as this can increase the chances of diabetes and obesity. It is also the appropriate point of the day to develop the thought intuitive and, given the peculiarities of the biological clock, for our liver to metabolize alcohol;

* between 9 and 11:59 pm: the internal body temperature drops and we begin to produce melatonin, a hormone that helps us fall asleep;

* between 12 noon and 2:59 am: levels of attention and alertness are lowered to a minimum, while melatonin reaches its maximum peak. On the other hand, the brain it begins to consolidate our memories and to discard the dispensable;

* between 3 and 5:59 am: we have our body temperature to a minimum and we are especially prone to asthma attacks and natural childbirth.
