I can hear your thoughts now… What do houseplants have to do with tennis? And the truth of the matter is – nothing. But they do offer tennis players a beautiful way to stay healthy during cold and flu season — and all the seasons in between! And the less time we spend sick means, the more time we can spend on the courts!
The role of household plants is not just to brighten up our living spaces and look nice on shelves. Many common household plants, such as ferns, palms, and ZZ plants, can actually purify the air and lower airborne viruses’ infectivity by raising humidity levels indoors. Yes, you heard that right! One of the secret weapons to fending off or dealing with the common cold or flu isn’t in your medicine cabinet. Rather, it’s on your windowsill.
According to research, when the humidity hits above 40 percent, it can greatly reduce the virulence and infectivity of the flu virus. Higher humidity also means lower infectivity of airborne viruses. This is where plants come in: all plants, except succulents and cacti, can increase humidity levels through a process known as transpiration.
“Transpiration occurs when direct sunlight strikes the leaves and pulls water from them into the air,” explains Christopher Satch, head of plant science and education at The Sill. “The plant, in turn, pulls water from the soil to replace the water that has evaporated into the air. The bigger the plant, the more transpiration that occurs and the more water that gets moved into the air. Humidity increases with increased transpiration, and having more plants and bigger plants raises humidity the most.”
So don’t be afraid to splurge on plants this year — not only do they purify the air we breathe, but they can also keep us healthy. Read ahead for 18 humidity-generating plants and where to buy them to help us stay healthy so we can play healthy!
