Houseplants have become a staple in modern home decor, celebrated for their ability to purify air, boost mood, and add a touch of nature to indoor spaces.
However, as the trend of indoor gardening continues to flourish, a growing concern has emerged among both health experts and enthusiasts - namely the potential dangers of sleeping with houseplants in the same room. While the benefits of indoor plants are well-documented, the lesser-known risks they pose, particularly in the context of the bedroom, really do deserve closer scrutiny.
Houseplants can improve air quality by absorbing carbon dioxide and releasing oxygen during the day - yet despite this, home health expert Neil McKenzie of emphasises that not all aspects of cohabiting with plants are beneficial.
He says: "While the presence of houseplants in your bedroom can offer numerous benefits, it's crucial to be aware of the potential dangers they may pose, especially for individuals with health conditions. By understanding and addressing the risks associated with nighttime oxygen consumption, mould, pests, plant toxicity, and air quality, you can enjoy the beauty and benefits of houseplants without compromising your health and well-being."
The Nighttime Oxygen Consumption

One of the primary concerns McKenzie highlights is the oxygen-carbon dioxide exchange process. While plants do produce oxygen during the day through photosynthesis, they switch to respiration at night. This means they absorb oxygen and release carbon dioxide, potentially competing with humans for oxygen in a confined space. Although the amount of oxygen consumed by plants at night is relatively small, in a poorly ventilated room or one with numerous plants, this could lead to lower oxygen levels, disrupting sleep and causing discomfort.
Mould and Allergens
Houseplants require a certain level of humidity to thrive, which can inadvertently create a breeding ground for mould and mildew. Mould spores can become airborne and exacerbate allergies or respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). McKenzie advises that individuals with sensitivities or respiratory issues should be particularly cautious about the types and number of plants they keep in their bedrooms. Regularly checking for mould growth and maintaining proper plant care are essential steps to minimise these risks.
Pests and Insects
Plants can attract pests like aphids, spider mites, and fungus gnats. These insects can become a nuisance and even cause allergic reactions in some individuals. Neil suggests inspecting plants regularly for signs of pest infestations and taking appropriate measures to control and eliminate these unwanted visitors. Introducing beneficial insects such as ladybugs or using natural insecticidal soaps can help manage pest problems without resorting to harsh chemicals.
Toxicity of Certain Plants
Some popular houseplants are toxic to humans and pets. Plants such as philodendrons, peace lilies, and certain varieties of ivy can cause adverse reactions if ingested or if their sap comes into contact with skin. For individuals with conditions such as skin sensitivities or compromised immune systems, exposure to these toxic plants can be particularly hazardous. McKenzie recommends thoroughly researching the plants you bring into your home, especially if you have children or pets. Opting for non-toxic plant varieties can reduce the risk of accidental poisoning.
Impact on People with Respiratory Conditions
For individuals with respiratory conditions such as asthma, COPD, or bronchitis, the risks associated with houseplants in the bedroom are more pronounced. The increased humidity required for plants can worsen symptoms, and the presence of mould spores can trigger respiratory distress. McKenzie advises those with these health conditions to be especially vigilant about plant care and to consider limiting the number of plants in the bedroom or opting for rooms with better ventilation.
Impact on People with Allergies

People with allergies to pollen, mould, or specific plants may experience heightened symptoms when sharing a room with houseplants. Allergic reactions can range from mild sneezing and itchy eyes to severe respiratory issues. McKenzie suggests that allergy sufferers choose hypoallergenic plants, such as succulents or ferns, and ensure their plants are free of dust and mould.
Maintaining Air Quality
To ensure a healthy sleeping environment, Neil advises improving ventilation in your bedroom. Opening windows periodically to allow fresh air in and using air purifiers can help mitigate the potential negative effects of having plants in the same room. Additionally, choosing plants known for their air-purifying properties, such as snake plants or spider plants, can be beneficial.
