Biophilia and indoor plants contribute to health and longevity

Scientific research suggests that incorporating plants into living spaces can positively impact neurological and physical health through the concept of biophilia. This innate human tendency to seek connections with life forms, a term supported by the work of psychologist Erich Fromm and biologist Edward O. Wilson, suggests that greenery can signal safety to the nervous system.

In Blue Zones—regions like Okinawa, Sardinia, Icaria, Nicoya, and Loma Linda where populations frequently exceed 100 years—gardening is a common shared activity alongside diet and social connection. Additionally, indoor plants can help mitigate indoor air pollution, which can sometimes be significantly higher than outdoor levels.

To maintain indoor vegetation, common kitchen ingredients can serve as effective natural fertilizers. Banana peels provide potassium and calcium, coffee grounds supply nitrogen, and crushed eggshells offer calcium. White vinegar can also be used in diluted form to balance soil acidity.
