On those hot summer days, sometimes it seems like there aren't enough ceiling fans in the world to ward off the warm. But fans and air conditioning aren't your only defenses against the heat. Some popular indoor plants can act as natural coolants, offering a more natural way to lower the temperature in your home and reduce your reliance on cooling appliances that cause energy bills to spike. According to NASA's Earth Science Study, plants release extra moisture from their leaves back into the air when their environment warms up. This process, known as transpiration, can help get stuffy air flowing and knock a few degrees off your thermometer. Bring a few of these cooling plants into your home so you can start reaping the benefits today.
Need a living room statement piece that will also provide a little warm-weather relief? Look no further than the ficus. Also known as Ficus benjamina or weeping fig, this leafy tree is excellent at keeping indoor air moist thanks to its bushy top of glossy leaves. You can even create a mini cooling ecosystem by placing a few other plants from this list around your ficus. Just make sure to keep your ficus hydrated if you position it under direct light.
No plant improves indoor air quality quite like a Boston fern. In fact, the NASA Clean Air Study found that this natural air purifier was especially good at removing volatile organic pollutants such as formaldehyde. In addition to filtering out toxins, Boston ferns are great humidifiers too. Dry, sunny spots are a fern's worst enemy, so be sure to place this super plant in filtered light and mist it regularly.
Most people know aloe vera for its ability to cool minor burns and sunburns, but it also has a high water content, which makes it one of the top plants for cooling down the home. Just remember that aloe vera plants love the sun and need to be watered regularly in the summer.
Like aloe vera, the snake plant has a high water content that makes it great at cooling down your home. Also known as mother-in-law's tongue or Sansevieria trifasciata, it does well in a sunny spot, so you can maximize the cooling effect by placing several of them in a window to help block the sun.

The bigger the leaves (and the greater number of them), the greater the cooling power. That's why the rubber plant, or Ficus elastica, can make such a big difference in air quality.

And like many of the plants on this list, it's also been shown to remove toxins like formaldehyde, benzene, xylene, and carbon monoxide. These plants will do best when under indirect sunlight.
