There are many reasons why hospitals may remove plants from patient rooms at night. One common belief is that plants and flowers deplete the oxygen in a room at night, potentially depriving patients of oxygen. However, this is a myth, as plants emit 10 times more oxygen than they use up during the day, and only alter oxygen and carbon dioxide levels by about 1.5% at night. Another reason could be the risk of bacterial infections, as flower water has been found to contain high counts of bacteria. Other reasons include the smell of flowers being more disturbing at night, the possibility of pollen allergies, and the risk of knocking over vases.
| Characteristics | Values |
|---|---|
| Reason for removing plants at night | Hospitals remove plants at night due to the belief that they compete with patients for oxygen, potentially causing "oxygen-starvation". |
| Validity of the belief | This belief is a myth. Plants typically absorb carbon dioxide and emit oxygen, but at night, this process changes, and they absorb more oxygen than they produce. However, studies have shown that even at night, plants only alter oxygen and CO2 levels by about 1.5%, which is negligible. |
| Other reasons for removing plants | Hospitals may remove plants due to infection control requirements, the risk of pollen allergies, the smell of flowers, and the potential for vases to be knocked over. |
| Benefits of plants in hospitals | Plants and flowers have been shown to improve patients' mood, reduce blood pressure and pain levels, and lower ratings of anxiety and fatigue. |

Hospitals remove plants at night due to the belief that they compete with patients for oxygen
The oxygen-sucking myth, as it is commonly referred to, has been traced back as early as 1923 and has been pervasive in hospital policies. While the concern for oxygen depletion in hospital rooms seems logical, it is important to note that flowers add far more oxygen to a room than they use. In fact, a hospital room with flowers will have higher oxygen levels than one without. Additionally, the amount of oxygen used by plants is minuscule compared to the oxygen consumption of a human being.
The removal of plants from hospital rooms at night may also be attributed to other factors. For example, the smell of flowers can be more disturbing to patients at night. Furthermore, certain flowers may release pollen, causing allergic reactions, and the water in flower vases may contain bacteria, although there is no evidence that this has caused hospital-acquired infections. The presence of flowers and plants in hospitals can also be time-consuming for busy staff to manage.
Despite the myths and concerns surrounding plants and flowers in hospitals, several studies have shown that they have beneficial effects on patients. Research has indicated that patients in hospital rooms with plants and flowers experience improved mood, reduced pain, lower blood pressure, and decreased anxiety and fatigue. The presence of plants and flowers in hospitals can also be culturally significant, as the giving and receiving of flowers is an important tradition for many people.
While the belief that plants compete with patients for oxygen may have led to the removal of plants from hospitals at night, it is important to consider the weight of evidence against this idea. The positive impact of plants and flowers on patient well-being, coupled with the negligible effect on oxygen levels, suggests that the benefits of having plants in hospital rooms may outweigh the concerns.

Potted plants are removed from intensive care wards due to the risk of infection
Potted plants are often removed from intensive care wards in hospitals due to a variety of factors, including the risk of infection, oxygen depletion, and maintenance requirements. While the positive impact of plants and flowers on patients' mental health and well-being is well-documented, hospitals must also prioritize infection control and patient safety.
Infection control is a critical concern in intensive care units, where patients may be immunocompromised or at higher risk of infection. Potted plants, particularly the soil they contain, can harbor bacteria and increase the risk of hospital-acquired infections. This risk is significant enough to warrant the removal of potted plants from these wards. Additionally, flowers and plants can be a source of pollen, which may trigger allergic reactions in some individuals, further complicating their health status.
The belief that plants and flowers deplete oxygen levels at night is a common misconception. While it is true that plants absorb oxygen and release carbon dioxide during the night, the impact on overall oxygen levels in a hospital room is negligible. Studies have shown that even at night, plants only alter oxygen and carbon dioxide levels by approximately 1.5%, which is not a cause for concern. However, this myth has persisted and may have influenced hospital policies on plants in intensive care wards.
Another factor contributing to the removal of potted plants is the maintenance they require. Watering plants and changing their water regularly can add to the workload of already busy healthcare staff. Additionally, vases and pots can be knocked over, creating hazards and increasing the risk of accidents. These considerations, along with the potential for flowers to produce strong odors, especially when they are old, further reinforce the decision to remove potted plants from intensive care wards.
While the benefits of plants and flowers in hospital rooms are recognized, the decision to remove them from intensive care wards is a careful balance between patient well-being and maintaining a safe and manageable environment. Hospitals must adhere to stringent infection control measures and prioritize the specific needs of patients in critical care.

The smell of flowers can be disturbing to patients at night
Another concern related to the smell of flowers in hospitals is the potential for allergic reactions or respiratory issues. While flower pollen rarely causes allergic reactions, the strong scent of flowers can sometimes trigger allergies or asthma, particularly in patients with respiratory conditions. Additionally, old flowers can emit an offensive odour, which can be unpleasant for patients and staff.
The smell of flowers can also interfere with the sense of smell, which is crucial for maintaining a healthy environment in hospitals. A pleasant aroma can help mask unpleasant odours, such as those from medical procedures or sick patients, providing a more comfortable environment for recovery. However, a strong floral scent can also be distracting or overwhelming, especially for patients with sensitive senses or those experiencing nausea or headaches.
Furthermore, the presence of flowers in hospital rooms can create additional work for busy hospital staff. Flowers require regular care and maintenance, including watering, trimming, and cleaning. In busy hospital wards, the time and resources required to maintain flowers may be better allocated to more pressing patient care needs. Additionally, vases and flower arrangements can take up valuable space in hospital rooms, which are often already limited in terms of space and storage.
While the smell of flowers can be disturbing to patients at night, it is important to note that flowers have also been associated with positive effects on patients' well-being. Studies have shown that patients in hospital rooms with flowers and plants experience reduced pain, lower blood pressure, and improved mood and emotional states. The presence of flowers can provide a sense of comfort, cheerfulness, and connection to the natural world, which may aid in the healing process.

Old flowers can be offensively smelly and cause hazards if knocked over
Hospitals are busy places, and staff are often overworked. Flowers are sometimes seen as one more task for staff to manage, and so they are removed at night. While it is true that flowers emit carbon dioxide at night, this change from their daytime oxygen production is negligible in terms of air composition. A study in 1977 found that plants only altered oxygen and carbon dioxide levels in hospital wards by about 1.5 percent.
The removal of flowers at night is also related to a long-standing myth that flowers compete with patients for oxygen. This belief has been entrenched for a long time, possibly spreading by word of mouth. It is simply not true, as flowers add far more oxygen to a room than they use. However, the myth has been so pervasive that hospitals have incorporated it into their policies.
Flowers are also removed from hospital rooms at night due to the risk of spillage and the smell they produce. Old flowers can be very smelly and off-putting, and if knocked over, they can cause all sorts of hazards. Vases of flowers take up valuable space in hospital rooms and can be knocked over, causing spills and breakages. This is especially true in intensive care wards, where there is limited space and equipment that could be damaged by water.
In addition to the practical reasons for removing flowers at night, there is also a cultural aspect. Flowers are a culturally important way of expressing well-wishes and cheering up a hospital room. However, they can also be seen as a messy and time-consuming element of the healing process. This shift in the perception of flowers may be why they are increasingly treated in an ad-hoc manner by hospitals.

Hospitals may remove plants to save time and resources
Hospitals are busy places, and staff are often overworked and short on time. Flowers and plants can be a distraction and an additional task for staff to manage, especially in intensive care units. While the positive impact of flowers and plants on patients' mental health and well-being is well-documented, they can also be seen as a potential source of infection and a hazard, with vases at risk of being knocked over.
The belief that flowers and plants deplete oxygen levels at night is a pervasive myth that has been debunked by multiple sources. While it is true that plants absorb more oxygen and emit carbon dioxide at night, the impact on overall oxygen and CO2 levels in a hospital ward is negligible. A 1977 study found that plants only altered oxygen and CO2 levels by about 1.5%, which is insignificant compared to the oxygen usage of a human being.
However, the oxygen-sucking myth has been entrenched for a long time, with mentions of it dating back to 1923. This misconception, combined with the desire to save time and resources, may contribute to hospitals' decisions to remove plants and flowers at night or ban them altogether.
In addition to the oxygen depletion myth, there are other concerns associated with flowers and plants in hospitals. Some people worry about the potential for flower pollen to cause allergic reactions or for bacteria in flower water to lead to infections. While these risks are generally low, hospitals may choose to err on the side of caution, especially in intensive care wards where patients are more vulnerable.
Overall, while the removal of plants and flowers from hospitals may have multiple causes, including infection control and resource management, it is important to recognize that plants can also have positive effects on patient well-being. The decision to remove or restrict them is a complex one that involves balancing various factors to ensure the best possible care for patients.
