The Amazfit Band 5 device, one of the most demanded in Amazon, offers precise monitoring of sleep patterns, among other wonders."This smart band promises a repairing break," they secure about the IBAND+, a headband with different sensors.But the promises of some brands with their watches, bracelets and sleeping apps better take science.

Most of these accessories "measure the heart rate, which can be useful, but, with respect to sleep, they do not measure it correctly," the neurophysiologist with more than 20 years of experience and director of the master's degree in the Master in Sleep Medicine exposes itTech Institute, Óscar Larrosa Gonzalo.

The watches and apps to sleep better "do not work"

Asked about the Google Fit sports application, which in theory "allows you to register the dream and improve our routine," Larrosa assures that he can give a very generic idea, but does not measure the sleep structure with precision and, therefore, "it does not work"For concrete problems."It's a salehúmos," he warns.The same goes for the Samsung Galaxy Watch 4 Classic and the Amazfit Band 5.

If it is a clock that only wears wrist sensors "it is difficult for you to hit beyond the hours," adds this expert."They do not monitor precisely because they measure the dream in relation to the movement, something that is not 100 % real," says the specialist and director of Educa and Sleep, Rosa Rojano.

Electrode headbands

These experts agree that other devices such as headbands with electrodes (IBAND+, for example), which have more sensors, can monitor sleep phases with a little more precision.

But, in any case, it is a “biased information on how you sleep that for an individual usually behaves more inconvenient than benefits,” says Rojano.

Pros and cons

More and more people live obsessed with the steps they take, the calories they ingest and the hours they sleep, says Larrosa, who explains that applications and gossip that say they control and improve sleep have created a new disease.

This is orthosomnia."These devices make adults want to know at all times if their dream has been mild or deep, if they have slept so much, but do not know that 98 % of these devices do not succeed and are useless," summarizes the expert.

No scientific evidence

Both specialists insist that these types of devices do not have any scientific evidence contrasted in this regard, except for 2 % of the devices that do work.They are of medical use and is not sold in stores.

In addition, there are two large types of devices: "Those who are designed for very specific problems (such as sleep apnea), have more sensors and are scientifically accredited, and those of recreational use, which have no scientific evidence or contrasted benefit", Larrosa insists.

A business opportunity

Four million Spaniards have chronic sleep problems, according to the Spanish neurology (SEN), a figure that can be extrapolated to the rest of the world and explains that more and more electronic devices include miraculous functions that supposedly improve sleep.

"They are a business opportunity," criticizes Larrosa, who explains that no matter how much brands use a supposedly scientific language such as "control of brain waves", their accessories will not cease to be a "fallacy" because "there is a lot to develop"And "we don't have the necessary biological knowledge or technology," he clarifies.

Professional supervision

Rojano advises that "the ideal is that the devices that monitor sleep are only used when a professional recommends it" to assess whether there is a real problem.The vast majority of patients who come to consultation because they sleep badly find the cause in their habits and routines.

Before trying to reconcile the dream is also important to get away from any electronic device, as they are a light source that goes directly to the retina and stimulate the brain."We need darkness and try to leave the mind blank," summarizes Larrosa.Numerous physiologists claim that today, the human being sleeps worse than 100 years ago."It's a reality and the causes are several," adds this expert.
