If you've ever been in a fifth grade science class, you probably know that plants absorb CO2 from the atmosphere and expel the oxygen we breathe through a process called respiration. The health benefits of having increased oxygen levels in the air are numerous, but one of the most notable is its correlation with brainpower. Studies have shown that higher levels of oxygen encourage focus, and can even help alleviate symptoms of depression and anxiety. The spider plant (Chlorophytum comosum) is a particularly easy to grow indoor plant that makes NASA's pretentious "Best Air Cleaners" list. While also producing oxygen, it is a superstar at removing many common harmful volatile organic compounds (VOCs) such as benzene, formaldehyde, carbon monoxide and xylene.

Natural Humidifiers

Higher humidity temperatures have been linked to sinus relief, flu prevention, and even treatment for acne. But did you know that almost 10% of all moisture in the air comes from plants? In fact, a single areca palm (Chrysalidocarpus lutescens) can put over a quart of moisture in the air in in a day, and that's just one! While not all plants make good humidifiers (cacti, for one, retain most of their moisture and therefore don't add much to the air) the ones that do can certainly be a positive addition to any household.

Better Sleep

Some plants, specifically lavender (Lavandula) and Jasmine (Jasminum) have been shown to lead to a more restful night's sleep. Keeping either of these by your bedside can help induce a sense of ease and tranquillity, just by being in your vicinity! Getting a full nights sleep has never been easier (or smelled better)!

Natural Medicine

Many plants have medicinal benefits when grown and used correctly. A favorite of herbal users everywhere is the aloe vera (Aloe barberae) plant due to its many versatile healing abilities. The gel in the leaves is good for healing cuts and scrapes, as well as burns. In fact, fresh aloe is one of the best overnight cures for a sunburn, so if you're planning to go to the beach, it might be a good idea to keep some nearby! Beyond its already incredible external healing abilities, the leaves can also be boiled into a vapor that helps alleviate asthma symptoms.

They're Just Really Dang Cute

I mean really, is there anything quite as adorable and fun as picking out your own baby succulent from Lowes or local plant nursery? Maybe giving it a name and a special place on your windowsill? They're easier to care for than fish and cost a lot less too, whats not to love about these stationary, leafy pets? Plus, you don't have to clean their litter box. Score!
