Arkorespira® Best Breathe anatomical nasal dilator is a device that facilitates the entry of air into the nasal passages, thus improving breathing. Breathing through the nose is an involuntary act, and very important, in humans because the air is filtered, heated and humidified before entering the lungs. Through breathing, oxygen reaches every cell in our body and produces the necessary metabolic activity for its correct functioning. There are several factors that, on certain occasions, can obstruct the nasal passages. With the Arkorespira® Best Breathe Nasal Dilator, the nasal passages open for better air intake through the nose. In athletes, this increase in the volume of inspired air reduces the frequency and effort of breathing, helping to improve performance. During sleep, the relaxation of muscle mass causes many people to end up breathing through their mouths, making sleep more restless, light and often insufficient. In these cases, snoring, waking up with a dry mouth and throat and waking up tired are very common. The Arkorespira Best Breathe nasal dilator favors breathing through the nose, avoiding doing it through the mouth.
