The morning corresponds to the morning or the day and the evening to the afternoon or night.

What does morning and evening mean?

The terms morning and evening refer, respectively, to what refers to the morning schedule and what refers to the afternoon schedule. These are two terms from the Latin morning (“in the morning”), and vespertinus (“in the afternoon”), derived from the first of matuta (mater matuta), the Roman deity associated with the morning and venerated every June 11 by married Roman women; and the second of evening (“sunset”), from which the word “evening” also comes.

Therefore, morning affairs are those that are typical of the morning, or that are normally carried out at the beginning of the day; while evening affairs are typical of the afternoon or the beginning of the night. These terms are widely used to designate the schedules of performances of shows (such as cinema and theater, for example, in the “afternoon show”), radio and TV broadcasts (for example in the “morning programming”) , or school and work schedules (the “morning shift”, for example).

It is important to notice that there are no concrete and specific hours associated with each termbut these refer to “morning” and “afternoon” in very general terms that may imply different times.

Morning people and evening people

Some people reach their highest performance in the morning. and during the rest of the day they weaken or disperse, while others work in the opposite way. That is why people with morning habits (morning or morning people) and people with evening habits (evening or night people) are usually differentiated, depending on the time slot with the greatest energy, activity, and ability to concentrate.

It is thought that this difference between people it has to do with the production of melatonin in the body of each person: a protein linked to the deep states of sleep and that is secreted precisely during the moment of rest, either in its early stages or in the last stages of the sleep cycle. This is regulated, according to research by Joseph Takahashi in 1997, by a specific gene in the genetic information.

Thus, what distinguishes between morning people is that they secrete this compound at the beginning of the sleep cycle, thus allowing yourself to rest deeply for a longer time; while evening people secrete it at the end of the sleep cycle, so they usually wake up drowsy and without energy, ready for a rest that paradoxically they already had. This is why the evening ones improve their performance as the hours go by, while the morning ones worsen theirs as they run out of energy.
