Welcome to our informative blog post on plant therapy and the fascinating science behind using plants in hospitals. Have you ever wondered why hospitals often have indoor gardens or potted plants in patient rooms? The answer lies in the numerous benefits that plants provide to patients, staff, and the overall healing environment. In this article, we will delve into the scientific evidence supporting the use of plants in hospitals and explore how they can enhance the well-being and healing experience of patients.

The Benefits of Plants in Hospitals

The benefits of plants in hospitals are numerous and encompass both physical and psychological aspects. Let’s explore some of these benefits in detail:

Physical Benefits

  1. Enhanced Oxygen Levels: Plants are natural oxygen generators through the process of photosynthesis. They absorb carbon dioxide and release oxygen, improving the air quality in hospital environments. This increase in oxygen levels can promote better breathing and help patients feel more energized.

  2. Lower Blood Pressure: Multiple studies have shown that being in the presence of plants can reduce blood pressure. For example, a study conducted by Ulrich and his team in 1984 found that patients with windows facing leafy trees healed faster and required less pain medication compared to those with a view of a brick wall. This suggests that access to greenery and nature views can have positive effects on blood pressure and patient outcomes.

  3. Pain Reduction: Research has indicated that patients exposed to plants in their hospital rooms experience reduced pain levels compared to those without plants. This finding suggests that plants have analgesic properties and can contribute to pain management in healthcare settings.

Psychological and Emotional Benefits

  1. Stress Reduction: The presence of plants in hospital environments has been shown to reduce stress and anxiety levels in patients. A study published in the Journal of Physiological Anthropology found that patients with plants in their rooms had reduced stress hormone levels, lower heart rates, and improved psychological well-being. Simply gazing at plants and nature views can induce relaxation and provide a calming effect.

  2. Improved Mood and Well-being: Plants have the power to uplift mood and enhance overall well-being. The visual stimulation, scent, and colors of plants can create a sense of calm and positivity in patients. The use of indoor and outdoor gardens, potted houseplants, and attractive landscapes in hospital common areas can provide a visually pleasing and therapeutic experience for patients.

Therapeutic Approaches

  1. Horticultural Therapy: Horticultural therapy involves engaging patients in gardening activities as a form of therapeutic intervention. This approach allows patients to connect with nature, engage in a meaningful and calming activity, and contribute to their overall well-being and healing process. Horticultural therapy has shown positive effects on physical and mental health and coping ability, particularly in patients with chronic musculoskeletal pain.

  2. Biophilic Design: Biophilic design principles aim to incorporate natural elements, including plants, into built environments to enhance occupants’ well-being. In hospital settings, biophilic design focuses on creating spaces with visual access to nature, outdoor gardens, and restful courtyards. These design elements provide patients and staff with opportunities for interaction and restoration.


The scientific evidence supporting the use of plants in hospitals is extensive, demonstrating the significant benefits they offer to patients and healthcare staff. Plants not only contribute to the physical well-being of patients but also promote psychological healing and emotional well-being. From enhanced oxygen levels and lower blood pressure to stress reduction and improved mood, plants have a remarkable impact on the healing environment. Incorporating plant therapy through horticultural therapy programs and biophilic design principles can further enhance the healing experience for patients.

In conclusion, plants are not only aesthetically pleasing in healthcare settings but also play a vital role in promoting positive health outcomes. As we continue to explore the therapeutic potential of plants, their integration into hospital environments should be prioritized. By harnessing the power of nature, we can create healing spaces that support the well-being of patients and contribute to their overall recovery process.
