Finally, my years of being a plant lady has paid off: studies have shown that owning houseplants might just be the secret to overcoming dry skin!
Certain houseplants can naturally increase humidity in the air through the process called evapo-transpiration. We pour water into the soil for the plant, but some of that water also evaporates and enters the air over time. The rest of the water is absorbed through the plant’s roots, which then circulates the moisture through stems and leaves. Water reaches the leaves, evaporates into the air and increases indoor humidity, and that leads to more moisture in the air for your skin to absorb.
According to RHS chief horticultural scientist Tijana Blanusa, “House plants may be a simple and affordable way to reduce air dryness indoors and alleviate symptoms of dry skin, while providing multiple other benefits – for human psyche and physical health.”
Do note that the amount of evapo-transpiration depends the on the plant, size of the plant and space of the room. A 50cm x 30cm Peace Lily can emit over 100ml of water every day. That’s even more liquid than a whole bottle of Innisfree Green Tea Seed Serum! While not all that water will absorb into our skin, the moisture being added into the air increases humidity and any increase in humidity helps the skin to not dry out so fast.
Picking the right plants is also very important. For example, a cactus won’t be of much help compared to a large tropical plant. The indoor plants with the highest rate of transpiration are:
- Areca Palm
- Rubber Plant
- Peace Lily
- English Ivy
- Spider Plant
Need more convincing? A study done by NASA showed that certain high-transpiration plants could actually remove up to 87% of indoor air pollutants. Being surrounded by nature has also shown to have a positive effect psychologically, and speaking as a plant lady myself, I can vouch for the fact that having plants around me does make me feel happier.
