50% of adults suffer insomnia at some point in their lives, a disorder that almost always is a symptom of another problem and, therefore, to treat it, it is necessary to act on the cause that originates it.
Sleep is an essential physiological state for life, and quality and quantity directly affect the health of the individual. Among the physiological functions of sleep is to self-regulate the functions of the central nervous system and other tissues, restore the cellular energy reserve centers and store the data in memory.
What is imsomnia?
The insomnia is a sleep disorder (dyssomnia according to an international classification ASDA), which is the inability to sleep in quality or quantity sufficient to feel rested and active the next day. It is characterized by the difficulty to reconcile or maintain sleep, early awakening and a non-restorative sleep, given appropriate circumstances and the opportunity to have it.
The amount of sleep necessary is variable in each person and is genetically determined; a newborn sleeps about 18 hours, a young adult from 7.5 to 8 hours and an elderly person about 6.5 hours. From the third to the sixth decade of life there is a gradual decrease in the quality of sleep, becoming more fragmented and superficial.
Insomnia not only affects the individual at night but during the day, which is when he suffers the consequences of insufficient rest, such as fatigue, lack of energy, difficulty in concentration and irritability, which can translate into low work performance, increase in the percentage of accidents, easier to get diseases, etc.
Between 10 and 15% of the adult population suffers from chronic insomnia, while around 50% of adults suffer from insomnia at some point in their lives, and 25-35% have had occasional or transient insomnia, due to stress caused by various situations. It affects women more frequently, although there is an increase in the rate of insomnia in men throughout their lives and even in children, probably in relation to current lifestyle habits.
In most cases, insomnia is a symptom of another existing medical, psychiatric, circadian, behavioral or environmental disorder, rather than a disease in itself; Therefore, when treating it, one must act on the cause that originates it, and not only on the symptoms.
