Scientists claim that houseplants are good for health because they improve air quality and increase oxygen levels.
Plants that require a lot of water and sunlight improve the atmosphere through their growth process. It provides for the release of water vapor into the air, the absorption of carbon dioxide and the release of oxygen.
This in turn could be a "simple and affordable" way for people to reduce their risk of dry skin and respiratory problems or conditions, the researchers said.
Scientists from the University of Reading and the Royal Horticultural Society conducted a study on various plants and how they change the air around them.
They discovered that the peace lily and ivy were the best because they receive very large amounts of carbon dioxide and water.
Dr Tijana Blanusa said: "We know that people spend most of their time at home. "Plants with high levels of perspiration - that is, the most 'thirsty' plants that need more water to grow well - and large leaves, offer many moisture-related benefits."
"Indoor plants can be a simple and economical way to deal with the dry atmosphere and relieve the symptoms of dry skin, while providing other benefits for mental and physical health," say experts.
Higher levels of moisture in the atmosphere mean that the skin is better hydrated and less likely to develop dryness.
Dehydrated skin causes irritation and worsens them respiratory infections.
Previous research has shown that the flu is more difficult to spread in environments with higher humidity because viruses cannot be transmitted so easily.
The study was published in the scientific journal Air Quality, Atmosphere & Health.
