New Study Reveals Ideal Amount of Indoor Plants for Well-Being

URGENT UPDATE: A groundbreaking study from Stanford University reveals that having the right amount of indoor plants is crucial for well-being, with an optimal greenery level set at 20%. Too many plants can actually increase stress, transforming your tranquil indoor oasis into a source of anxiety.

The research, led by Eva Bianchi, involved 412 participants who were placed in digital conference rooms with varying amounts of indoor greenery. The study found that when participants perceived plants in about one-fifth of their environment, they reported significant boosts in restoration and a sense of belonging. This translates to approximately 17 plants in a room of 13 square meters, complemented by a view of tree canopies.

However, researchers discovered that exceeding this threshold—specifically when total greenery reached 60%—led to increased stress levels among participants. Bianchi noted, “I wasn’t expecting this at all,” emphasizing that an overload of plants could overwhelm individuals and hinder productivity. Participants expressed feelings of being overwhelmed, with some describing the environment as “too many plants” and “a nightmare to try to get anything done.”

The findings are especially relevant as the indoor plant trend surges, particularly among Millennials and Gen Z, with surveys indicating that two-thirds of American households now have at least one indoor plant. The study highlights the importance of not just the presence of plants but the connection individuals feel towards them. Those who felt more in tune with their greenery experienced greater mental and physical health benefits.

The Nature View Potential tool, developed as part of this study, measures the sightlines of greenery within a room, allowing designers to optimize plant placements for maximum comfort and calm. This research has significant implications across various settings, including workplaces, schools, and hospitals, where the right amount of greenery can enhance productivity, concentration, and recovery rates.

Looking ahead, the team hopes their findings will guide future designs to ensure that indoor spaces promote well-being without overwhelming occupants. As the houseplant craze continues to grow, understanding the balance of indoor nature has never been more critical.
