Intact nasal mucosa prevents viral attacks – you get protection even from corona


The immune system is not a mere innate automatic setting that remains the same from cradle to grave, but can be affected by itself.

Each of us also has a so-called learned resistance that will be honed and developed over the years. It is enhanced by healthy habits such as a varied diet rich in vegetables and fruits, regular exercise, stress management and a 7-9 hour night’s sleep.

Due to poor lifestyle and stress, many people have a silent inflammation in their body. It also increases the susceptibility of the corona to infection, as the immune system will not be able to fight pathogens such as viruses optimally.

Close the mucosal gate

It is generally thought that an intact, healthy mucosa is the first barrier against viruses, explains Matti Waris, Docent of Virology at the University of Turku.

The most important function of the nasal epithelium is to remove foreign particles from the airways.

– Many viruses infect precisely these cells and their infection suppresses the function of the cilia, causing the secreted mucus to cough out, docent Matti Waris says.

For example, in chronic sinusitis, impaired function of the cilia is part of the problem.

According to Waris, some natural substances, such as menthol, may accelerate the movement of the cilia. Nasal sprays, in turn, can help relieve a short-term nasal congestion caused by the flu.

Air moist but moderate

Adequate moisture levels are essential for mucosal health. Inherently, this is facilitated by adequate hydration and nasal inhalation. It has also been suggested that a humidifier is a good way to keep mucous membranes moist and fight viruses.

According to studies in China, moisture may not directly affect the virus itself, but it makes the virus particles heavier. Therefore, they fall out of the air faster when a sick person breathes, coughs, or sneezes into a room.

Research Director Seema Lakdawala therefore, the use of a humidifier is probably a good idea against viruses.

The respirator instructs that the humidifier must be of the correct capacity in relation to the surface area of ​​the room and must be positioned in accordance with the manufacturer’s instructions. It is good to remember that excessive humidity inside can promote the growth of mold, bacteria and dust mites.

Now is the best time to quit smoking

The coronavirus is dangerous to the lungs and also causes pneumonia.

In smokers, the lungs are already under heavy load, so along with covid-19 infection, the situation is very risky.

Tobacco paralyzes the nasal cilia and it is the healthy cilia and mucous membranes that prevent viruses from entering the body.

One of the fastest ways to drop your risk of infection is to smoke tobacco as you like. According to experts, there can be no better time to quit smoking.

Within a few days of cessation, mucosal function begins to recover and has a resistance-enhancing effect. This is also true for those who have been burning for years.

Did you know why soap is better than a rinse?

We are instructed to wash for at least 20 seconds. Soap washing bites viruses better than hand rinsing, as it literally blows them up.

On the skin, the hydrophilic end of the soap molecule attaches to the water molecules and the water-repellent end to fatty substances, such as the protein branches of the coronavirus.

When rubbed long enough, the viruses will tear to pieces.
