As the flu season sweeps across Japan, a report has emerged detailing the correct use of humidifiers as a crucial combatant in preventing the infection. The feature elucidates the importance of maintaining an optimal humidity level in households, potentially helping people stay healthy during this pivotal period. While everyone from children to elderly is vulnerable to the viruses, this preventive measure is being strongly suggested to minimize the risk.

The use of humidifiers during winter, particularly the flu season, is common in Japan due to the dry indoor atmosphere main qualities from heaters. The population largely believes in maintaining a proper humidity level to counteract the drying effect of heating systems and potentially inhibit the spread of flu viruses.

In the United States and European Union, the use of humidifiers also plays a part in health recommendations, but the emphasis is more on personal hygiene and vaccination. While the use of humidifiers has not been widely promoted as a protective measure against the flu, they are commonly used for comfort, especially in dry climates or for people suffering from respiratory issues.
