In cold and dry winters, the nose and bronchi may become swollen and narrow, leading to symptoms such as stuffy nose, sneezing, and coughing. Even the skin, which was not a problem with oil, is white and itchy and itchy. Since 60-70% of our body cells are made of water, problems occur in the stratum corneum of the skin surface in winter when moisture is insufficient. Atopic dermatitis can worsen because it is more affected by dry weather because there is a malfunction in the stratum corneum.
For this reason, a humidifier is used in winter, but care should be taken in using a humidifier. This is because bacteria and fungi are easily formed in the water accumulated in the humidifier. If a contaminated humidifier is used, water vapor, including bacteria or fungi, can penetrate into the bronchi and cause bacterial pneumonia or irritable pneumonia. In order to use the humidifier safely, it must be cleaned daily, and when the humidifier is not in use, the container must be completely emptied and stored in a dry condition.
Professor Jeon Yoo-hoon of the Department of Pediatrics and Adolescents at Hallym University Dongtan Sacred Heart Hospital said, “The ultrasonic humidifier has relatively large moisture particles, so water droplets contaminated with dust or bacteria can enter the bronchi, and the vaporizing humidifier can contaminate the humidification filter or the humidifying disk.” “Even though there are differences in the vaporization method depending on the type, it is important to keep all humidifiers clean.”
On the other hand, if your skin is dry, it’s not good to wipe it off when you wash your face or take a bath. The stratum corneum of the skin is rich in natural oils such as ceramide, and if you wipe the oil so that all of the oil film is damaged, or if you push the dirt with a dirt towel, the skin will not be able to perform its own function, the’skin barrier function’. When using a cleanser, it is better not to use a strong cleanser that will wash away the oil film and use a mild, mild cleanser that does not irritate the skin.
Also, because the nose is dry, sometimes saline or water is added to the nebulizer machine prescribed by the hospital at home and water vapor is breathed into the nose. This is a mistake. The nebulizer is a machine designed to be used to treat asthma.Since the solution put in the machine is vaporized and sprayed into a very small gas that can enter the bronchi, contaminated saline or water can lead to dangerous consequences of infection of the bronchi. If the nasal cavity is dry, the best way to control the humidity in the house is to use a sterile saline spray.
Prof. Jeon Yu-hoon said, “With the spread of Corona 19, the amount of time indoors is increasing, but modern houses and heating methods have difficulty maintaining adequate humidity.” “Proper indoor humidity is 50-60%, and in winter, this humidity. Because it is not easy to maintain, you should pay attention to humidity control by using various methods such as plants to control humidity and hanging wet towels. Drinking enough fluids is also important to prevent dryness of the skin, nasal mucosa, and bronchial mucosa.”
