Trees and plants make the world infinitely better and healthier just by existing. The greenery is a sight for sore eyes, whether outside in nature or around you as houseplants. 

Houseplants are not only visually appealing and an aesthetic decor choice, they also provide a plethora of benefits to your overall health and life. 

  • Plants take in carbon dioxide and give out oxygen during photosynthesis (the process by which plants use sunlight, water, and carbon dioxide to make food). Thus, houseplants improve oxygen levels in the air indoors and make its quality better. In fact, a study done by the US space agency NASA (National Aeronautics and Space Administration) had established that houseplants can remove up to 87% of toxins from the air in 24 hours. 

  • They also release water and increase the humidity level in a room, which helps in keeping many respiratory problems at bay. 

  • Houseplants remove volatile organic compounds [(VOCs), for example, formaldehyde, benzene, xylene, trichloroethylene, etc.,] found in house objects, such as rugs, books, grocery bags, and paints, and trapped in the air inside homes. Plants purify the air by pulling these contaminants into soil, where microorganisms degrade them.

  • They are known to improve concentration, boost productivity, reduce stress levels, and uplift your mood.

People around the world have been stuck indoors for more than a year owing to the COVID-19 pandemic and will be confined to their houses for longer periods than before. 

It is natural to miss the connection that humans feel with nature, and the solace it offers in difficult times. Looking after houseplants and being surrounded by greenery could provide a much-needed boost to your mental health.
