Gone are the days when plants only belong to gardens. Bringing a piece of nature inside one’s home is now highly recommended. Finding a perfect houseplant can be quite a work since there are other things to consider such as the lifestyle of the homeowner. For example, if the owner has a busy schedule, they should opt for a low-maintenance plant which requires minimal watering. If the owner has a cat or dog, then they should settle for those that are pet-friendly.
And of course, adding houseplants is also considered as a great way to add an extra oomph to any room in your home since some plants can bring a pop of color. Of course, plants should go beyond than just being a design, as its perks outweigh its visual beauty. Believe it or not, there are many benefits one can reap even from just a tiny plant.
1. Houseplants assist humans in breathing
Plants produce oxygen that humans need to live and at the same time, humans give out carbon dioxide to the plants. Humans need all the oxygen they could get, and plants help increase the oxygen levels.
However, just like humans, plants respire like humans at night—meaning that they take in oxygen and release carbon dioxide. Plants such as succulents, orchids, and epiphytic bromeliads do the opposite by releasing oxygen and receiving carbon dioxide. These plants are recommended to be placed in bedrooms for a fresher air during night time .
