There are a number of causes that alter, interrupt or delay sleep; and that, in addition, they are directly responsible for prolonged insomnia scenarios. Among them are alterations of external origin to the sleeper, such as noise or movements, and those of internal origin, whether at a physical, emotional or neurological level.
One of the most common neurological conditions through our nervous system and that occurs in 10% of the population synchronously, although it is very possible that most people experience it at some point in their life, is the well-known like nervous, anxious feet syndrome, or RLS: Restless Legs Syndrome, in medical parlance. However, it is also known as Willis-Ekbom disease, since Thomas Willis was the one who first described this symptomatology in the 17th century, and Karl Ekbom who documented it in 1944.
That’s how it is. If before sleeping or during moments of rest, when your body is in a resting, lying or lying position, you feel a sensation in your legs or feet, which urges you to move them continuously and quickly, you should be aware of the symptoms , causes and possible ways to counteract this feeling of anxiety. Let’s see in depth what this medical condition is about, which is attributed detriment to physical health due to the insomnia it generates in those who suffer from it.
This syndrome is described as a sensory and motor disorder, at the level of the nervous system, in which the sufferer feels an uncontrollable desire to move the limbs and legs due to a sensation of discomfort that is difficult to describe, but associated with despair, pangs. , tingling, vibrations, squeezes, etc., which cannot be located in a specific place on the body, but is initially evident in the lower extremities and feet. Around half of the people who suffer from this symptomatology manifest pain pictures on some occasions.
The highest peak of activity in affected people occurs during periods of rest or rest, commonly when the sleeper is about to fall asleep. This triggers long periods of insomnia in which the person, trying to avoid the feeling of nervousness and anxiety in their extremities, constantly moves their feet and continually adjusts seeking sleep.
A large number of sufferers express the need to continually get out of bed in order to change the physical sensation of the body. After moving around, walking for a few moments, and going back to bed, they try to sleep quickly, before RLS appears again. Serious cases of people sometimes unable to sleep through the night have been documented.

The population groups affected by this disease are normally the oldest, with the percentage increasing after the age of 40, but cases have been recorded in all ages, so anyone can suffer from this syndrome. Similarly, it seems to affect women more than men, although not with a large percentage difference. In the stage of pregnancy or gestation it occurs in a greater proportion, repeating itself during subsequent deliveries.
The main causes of RLS are associated with four groups: the nutritional field, family and hereditary history, diseases and comorbidities associated with RLS, and sleep hygiene. It is worth noting that, although there is extensive documentation and medical research on this syndrome, it is still a very unknown clinical picture, so there is no defined cause or group of pathologies that fully explain it. However, these aforementioned causes are directly associated with the appearance of RLS in the observed patients. Let’s see each one.
First, in the nutritional field, it has been detected that iron insufficiency has a direct influence on this syndrome, since a lack of dopamine regulation is generated, which alters the functioning of the nervous system, triggering physical sensations such as RLS. Second, it has been found that this syndrome has a hereditary component, so it is worth investigating the family history to find out if our blood ancestors also suffered from it. Third, it has been well documented that people who suffer from comorbidities and diseases associated with kidney failure or gastrointestinal conditions have a high risk of RLS due to the difficulty in absorbing nutrients and minerals such as iron. Likewise, patients with neurological diseases such as Parkinson’s disease and associated diseases are exposed to suffering from RLS.
Treatment for RLS is divided into two branches. One, pharmacological, for severe or chronic cases; in this scenario, according to medical assistance, drugs are prescribed to control the nervous system. However, in most cases, which commonly treat 90% of affected people, this syndrome is treated by generating a nutritional balance rich in iron for the patient’s diet, accompanied by certain exercise habits and routines that generate a response in the nervous system. In addition, it usually relies on the so-called sleep hygiene, all the habits and predispositions to generate an induction into deep and continuous sleep: going to bed at regular times, avoiding food and drinks that interrupt sleep, having the rest space to sleep , etc.
