Sure, they’re nice to look at, but what if I told you there are actual health benefits of indoor plants? Your next houseplant purchase should be considered a win-win!

What, exactly, are the health benefits? Read on to find out…

The Health Benefits of Indoor Plants

#1: They’re natural humidifiers.

A horticulturist explains:

How does a plant increase humidity? Like humans, plants sweat a lot! Most of the water a plant absorbs through the roots travels up the plant and is eventually lost as water vapor through tiny holes in the leaves. This process is called transpiration. In fact, most plants lose 90% or more of their water through transpiration (a fully grown tree can easily lose several hundred gallons of water in a single day from transpiration). This evaporation is what helps pull water from the roots all the way to the leaf tips.

Research suggests that indoor relative humidity may positively impact health:

The influence of relative humidity on the abundance of allergens, pathogens, and noxious chemicals suggests that indoor relative humidity levels should be considered as a factor of indoor air quality. The majority of adverse health effects caused by relative humidity would be minimized by maintaining indoor levels between 40 and 60%. This would require humidification during winter in areas with cold winter climates.

I used to think I needed a machine humidifier to breathe easier each night; now, I just keep three plants in my bedroom windowsill!

#2: They help purify the air.

Research has shown that poor air quality can cause health problems, especially in children.

According to a NASA study, the following air toxins are commonly found indoors:

  • Formaldehyde
    • Found in virtually all indoor environments.
    • Major sources: foam insulation; particle board or pressed-wood products; paper products (e.g., grocery bags, waxed papers, facial tissues, and paper towels); household cleaning agents; resins used as stiffeners, wrinkle resisters, water repellants, fire retardants, adhesive binders in floor covering, carpet backing, and permanent-press clothes; heating and cooking fuels such as natural gas and kerosene.
  • Benzene
    • Found in basic items including gasoline, inks, oils, paints, plastics, and rubber.
    • It is also used in the manufacture of detergents, explosives, pharmaceuticals, and dyes.
  • Trichloroethylene
    • Used in printing inks, paints, lacquers, varnishes, and adhesives.

The solution? Buy more houseplants! In the same NASA study, researchers found that low-light requiring plants can improve indoor air quality; they drastically reduce the presence of air toxins, such as the ones mentioned above.

Which plants are best?

For best air purification results, you should have one plant per 100 square feet.

#3: They may boost your mood and mind.

According to Healthline.com, plants may help us relax, stay optimistic, and think smarter:

Who knew plants were so cool?

(Bonus: Apparently, you can buy plants on Amazon!)

Bottom line: Plants are so much more than just a pretty face, so we should stop judging them solely based on appearance! Purchase your own indoor plants to humidify and purify your air, boost your mood, and enhance your mind! Do you already have indoor plants, or do you plan to buy some?
