If you’re looking for a way to celebrate Earth Day this year, consider buying some plants for your house.

Not only are they good for the environment, but they can actually aid in improving your mental health.

House plants can produce oxygen and remove toxins from the air, which can help your brain work more effectively, according to Dr. Susan Albers, a psychologist with Cleveland Clinic.

In fact, research shows they can promote focus and concentration.

Plants can also give you a sense of purpose and fulfillment, since you have to water them on a regular basis and make sure they’re growing.

Another perk is that they’re visually pleasing and can spruce up any room.
