rhume et froid: pourquoi on s'enrhume, prévention, et traitement.

Colds are more common in winter, when it's cold, but why? Confinement and overcrowding don't explain everything, and there's another reason, which is linked to the nasal mucosa. This nasal mucosa produces microvesicles that play an anti-infective role. They contain molecules that prevent viruses from attaching to nasal cells, an essential step for them to infect us. They then produce microRNAs that attach to the viruses and prevent them from multiplying. However, when it's 4°C outside, the nasal mucosa is at 32°C. And at this temperature, the anti-infective defenses produced, vesicles, and microRNAs, are reduced by half. The solution is to protect your nose with a scarf or a mask, which limits the drop in temperature. Treatment for colds, however, relies mainly on nasal irrigation. You can use essential oils, local vasoconstrictors, or antihistamines. These last products can relieve the uncomfortable sensation of a stuffy nose. (In case of fever, which is rare with the common cold, paracetamol, NOT EXCEED 3 grams/day) #medicine #health #cold #healthandlifestyle #treatments 00:00 introduction 01:04 the nasal mucosa 02:30 nasal mucosa in the cold 04:10 consequences, prevention of colds 05:08 cold treatment and conclusion
