Even though it is regularly required for children, adults often underestimate the importance of effective daily nasal cleansing.  Many experts agree that we should encourage nasal cleansing just as we encourage the use of toothbrushes for oral hygiene.  As the ancient holistic disciplines, and especially yoga, remind us, breathing is life.

Those with children understand the importance of nasal cleasning, which gets rid of nasal mucus and prevents the development of complications caused by bacteria, such as sinusitis and colds. Nasal irrigation, especially before sleeping,  is very important for infants, who for up to 6 months of age, breath using their nose, and for infants who are not able to breathe through their mouth while being breastfed. Many people don't know that nasal cleansing is useful at all ages, and in fact it has been used for thousands of years in holistic disciplines and yoga, for which the nose and upper airways are the main channels through which  “prana”, or the life energy that nourishes and provides health benefits to the entire body, passes.
Nasal cleansing, through nasal douches, or irrigation, should be a daily habit just  as oral hygiene and it would be correct to educate children from an early age.
Especially for those who live in cities, where the air is polluted by elements which excessively dry up nasal mucosa, and is full of bacteria and allergenic factors, nasal cleansing allows for better breathing, prevents the accumulation of mucus and helps keep clean the part that directs the air we breath to the lungs deeper airways. Those who regularly practice nasal cleansing, just as those who practice yoga, claim to have a greater ability to perceive and recognize flavors and tastes, as well as smells and perfumes.
As a matter of fact, there are a growing number of doctors  who claim that air pollution, which weighs down with the air we inhale with harmful dust, and the fact that people spend more time in air-conditioned environments where it  is difficult to know the real hygiene conditions of the filters used, are among the main causes of respiratory allergies.
The main function of our nose is to filter and "trap" the harmful particles in the air to prevent them from reaching the lungs. Once they are trapped, the body needs to expel these particles, so as not to contaminate the airways and it does this through mucus, which must be removed.
There are many products on the market for proper nasal cleansing.  What is needed is a sterile saline solution and an apparatus to administer it: there are devices specifically designed for this purpose or devices for aerosol therapy can be used.  The ideal device is one that allows for micronized nasal irrigation, because the microscopic droplets generated have an extraordinary ability to reach the deepest parts of the respiratory tract. The flow should be regular and continuous: this allows for a reduction in the time of application and maximises effectiveness. The best option, of course, is to have a regulator which allows you to adjust the flow as needed. There are other elements that may influence selection, from the device's ergonomics to its design: today these devices are designed to minimize the need to remain still in front them during therapy, thanks to the ability of some devices to rotate allowing them to "follow" the movements of the user.  At the same time, due to the storage containers and hooks, the need to move away from the device to get accessories is reduced to a minimum.  Even size can be an important factor to consider in small city apartments (there are portable micro-piston devices that can fit in the palm of your hand). There are also devices with playful and fun designs, ideal for distracting and entertaining children during each session.  Everyone will surely find a solution best suited to them. It is true, though,  that if you intend to follow medical recommendations and make nasal cleansing  a daily habit for both children and adults, it is worth investing in a device designed for this purpose, which permits the use of accessories designed for the noses of adults and children: the diameter of the cone for inhalation, for example, is correct including at least two sizes, suitable for both the nostrils of a child, much smaller  in diameter, as well as those of an adult.
