The higher the humidity level, the more beneficial the immune system – has been shown to be linked with mild illness in people infected with SARS-CoV-2.

Dr Adriaan Bax, from the National Institutes of Health, said: “High humidity has been shown to mitigate the severity of flu and may have the effect of reducing the severity of Covid-19. a similar mechanism ”.

Higher humidity levels can help limit the spread of virus into the lungs through a mucosal cleaning mechanism – a defense mechanism that removes mucus and dangerous particles from the lungs.

High humidity has also been revealed to strengthen the immune system through the creation of special proteins called interferons that are capable of repelling viruses. Meanwhile, low humidity risks impairing the ability to self-clean the mucosa and inhibit the interferon reaction – which may be one of the reasons some individuals experience respiratory disease when it gets cold. .

The research process tested four types of masks as follows: N95, 3-layer medical mask, 2-layer cotton-polyester mask, and 1 thick cotton mask.

The results showed that all 4 of these masks raised the humidity of the inhaled air, to different degrees. At low temperature, the moisturizing effect of 4 masks increases significantly. At all temperatures thick cotton masks provide the greatest amount of moisture.

The new finding was introduced at a time when the US Centers for Disease Control and Prevention confirmed that wearing two masks at the same time can improve the level of SARS-CoV-2 virus transmission and transmission prevention.

Researchers at this center said that a face mask will prevent up to 40% of the carriers of the virus, while wearing a cloth mask on a medical mask can prevent up to 80% of the carriers. virus. If two individuals wear a mask, the level of virus suppression is up to 95%.

Therefore, choosing to wear a mask is the best way to prevent the spread of disease. Always carry with you quality masks.
