Categorization by GMDN

Categorized as "Therapeutic Air Ionizer" by GMDN (Global Medical Device Nomenclature). The category description is:

An electrically powered device for generating small, biologically active, negatively charged oxygen ions (e.g. reactive oxygen species (ROS)) that are released into the ambient air via a direct air stream to be absorbed into the bloodstream via the lungs and skin, and are intended to have a therapeutic effect for respiratory diseases, muscle function, improved sleep, and/or general health. It comprises an ionization chamber and a controller, and may additionally be configured to generate nitrogen anions, to remove pollutants/nanoparticles from ambient air, and/or to generate laminar airflow. It is intended for use in households and healthcare facilities.

Tested by ALCE

Disorders of sleeping through the night should not be treated directly with medication right from the start. It makes sense to first approach the cause of the problem. If you know a diagnosis or know what the problems with sleeping through are due to, you should first try to treat the problem with alternative medicine. Here, for example, we are talking about herbal medicines such as valerian, melissa, St. John's wort or lavender. Another alternative is a ionizer to name for the bedroom. This cleans and improves the air sustainably and ensures that the body can rest better. Both options are non-toxic and should be considered before prescribing sleeping pills.

The frequency and above all the duration plays a role in a sleeping disorder. Not everyone who wakes up more often during the night has a problem sleeping through the night. This only comes into effect if you wake up regularly during the night and lie awake for several hours or cannot fall asleep. However, if you feel that you are not getting enough sleep at night, you should consult your family doctor. In a sleep laboratory, your sleep behavior can be measured and assessed. Here it is important not to panic immediately, because even if you receive this diagnosis, you can proactively treat your difficulty sleeping through the night.

Insomnia can make you ill in the long run. On the one hand, a constant disturbance of sleeping through the night impairs cognitive abilities and mood. Accordingly, people with constantly interrupted sleep tend to be in a bad mood or even depressive behavior. In addition, if you regularly have trouble sleeping through the night, the risk of a rapid pulse, high blood pressure, sweating or even a heart attack increases.
