Humidity
Humidity is a natural remedy for the flu because high humidity builds up in enclosed spaces during cold weather. The extra moisture in the air can help thin out mucous in your sinuses, which prevents congestion and allows your body to fight off infection. However, it’s important to remember that while humidity can help ease some symptoms, it’s not a cure. So if you’re planning on using this remedy, make sure you aren’t also taking medication that could react with humidity—it’s best to consult a doctor before trying anything new.
A humidifier is one of the easiest ways to add moisture to your apartment, especially if you have central heating or an extremely dry climate. Humidifiers come in different sizes, so you can choose one that will fit into your home without being intrusive—it doesn’t need to be a permanent fixture.
If you have central heating or just want something simple, try placing a few bowls of water around the room. You can also use a humidifier, which will help add moisture to your home and make it more comfortable for you to breathe.
