The snake plant, also known as Sansevieria trifasciata or mother-in-law’s tongue, is a popular houseplant lauded for its striking appearance and low-maintenance nature. But beyond its aesthetic appeal, many people are curious about its potential health benefits, especially when placed in the bedroom. The question often arises: is it actually good to sleep next to a snake plant? Let’s delve into the science and anecdotal evidence to uncover the truth.
The Allure of the Snake Plant: Beyond Aesthetics
The snake plant has captivated plant enthusiasts for generations, and its enduring popularity stems from a combination of factors. It’s visually appealing, boasting upright, sword-like leaves that come in various shades of green, often with striking yellow or white variegation. This architectural form adds a touch of modern elegance to any space.
Beyond its beauty, the snake plant is remarkably easy to care for. It thrives on neglect, tolerating infrequent watering and a wide range of light conditions. This makes it an ideal choice for beginners or those with busy lifestyles who don’t have a lot of time to dedicate to plant care.
However, the appeal of the snake plant goes beyond just looks and convenience. Many believe that it offers significant health benefits, particularly its air-purifying properties. This perceived ability to improve indoor air quality is a major reason why people choose to keep snake plants in their homes, especially in the bedroom.
Unpacking the Air-Purifying Claims
The primary reason why people consider sleeping next to a snake plant beneficial is its alleged ability to purify the air. The central claim revolves around its unique photosynthetic process.
The Science of Photosynthesis
Plants, in general, absorb carbon dioxide (CO2) and release oxygen (O2) during photosynthesis, the process by which they convert light energy into chemical energy. This is why plants are often touted as natural air purifiers, helping to reduce CO2 levels in indoor environments.
Snake Plants: A Nighttime Advantage
What sets snake plants apart from many other plants is their ability to perform a specific type of photosynthesis called Crassulacean Acid Metabolism (CAM). Most plants open their stomata (tiny pores on their leaves) during the day to absorb CO2, but snake plants open theirs at night. This adaptation allows them to conserve water in arid environments, their natural habitat.
This nocturnal CO2 absorption is a key reason why snake plants are considered beneficial for bedroom environments. While you sleep, you exhale CO2. A snake plant working through the night can, in theory, help reduce the buildup of CO2 in the room, potentially improving air quality.
What the Studies Show About Air Purification
While the CAM photosynthesis of snake plants is established, the real question is whether this translates into a significant improvement in indoor air quality in a typical home setting.
One notable study conducted by NASA in the late 1980s explored the ability of various houseplants to remove volatile organic compounds (VOCs) from the air in sealed chambers. VOCs are emitted from common household products such as paints, furniture, and cleaning supplies, and can contribute to indoor air pollution.
The NASA study found that snake plants, along with other plants like spider plants and peace lilies, were effective at removing certain VOCs from the air, including formaldehyde, benzene, and xylene. These findings ignited interest in the potential of houseplants as natural air purifiers.
However, it’s crucial to consider the limitations of these studies. The research was conducted in tightly sealed chambers, which don’t accurately reflect the air exchange rates and ventilation found in most homes. In a typical home, with windows, doors, and ventilation systems, the impact of a single snake plant on VOC levels may be less dramatic.
The Realistic Impact on Indoor Air Quality
While a single snake plant might not completely eliminate all pollutants from your bedroom, it can contribute to a slight improvement in air quality. The key is to have a realistic expectation of what it can achieve.
For significant air purification, you would likely need a large number of plants, much more than what most people would practically keep in a bedroom. Consider the size of the room and the ventilation rate when assessing the impact of a snake plant.
Even a small improvement in air quality can be beneficial, especially for people with allergies or respiratory sensitivities. Reducing CO2 levels and removing some VOCs can create a slightly more comfortable and healthier sleep environment.
Beyond Air Purification: Potential Health Benefits
Beyond air purification, some anecdotal evidence suggests that sleeping next to a snake plant may offer other health benefits.
Reduced Stress and Improved Mood
Being around plants, in general, has been linked to reduced stress levels and improved mood. This is often attributed to the biophilic effect, the innate human connection to nature. Simply having a living plant in your bedroom can create a more calming and relaxing atmosphere, potentially promoting better sleep.
Increased Humidity
Plants release water vapor into the air through a process called transpiration. While the effect is small, snake plants can contribute to a slight increase in humidity levels in the bedroom. This can be particularly beneficial in dry climates or during the winter months when indoor air tends to be drier, helping to alleviate dry skin, nasal congestion, and other respiratory discomforts.
Aesthetically Pleasing Environment
Creating a visually appealing and comfortable bedroom environment is crucial for promoting good sleep. A snake plant can add a touch of greenery and visual interest to the room, making it a more relaxing and inviting space.
Addressing Potential Concerns: Are Snake Plants Safe for Bedrooms?
While the benefits of sleeping next to a snake plant are often highlighted, it’s important to address potential concerns about safety.
Toxicity
Snake plants contain saponins, which are considered mildly toxic to humans and pets. If ingested, they can cause nausea, vomiting, and diarrhea. Therefore, it’s important to keep snake plants out of reach of young children and pets who are prone to chewing on plants.
While the plant is toxic when ingested, sleeping next to it poses very little risk. The plant releases no harmful chemicals into the air that could be inhaled.
Allergies
Although uncommon, some people may be allergic to snake plants. Allergic reactions can manifest as skin rashes, itching, or respiratory symptoms. If you suspect you have a snake plant allergy, remove the plant from your bedroom and consult with a doctor or allergist.
Overwatering and Mold
Overwatering snake plants can lead to root rot and the growth of mold in the soil. Mold can trigger allergies and respiratory problems in sensitive individuals. It’s crucial to water snake plants sparingly, allowing the soil to dry out completely between waterings. Ensure that the pot has adequate drainage to prevent waterlogging.
Tips for Incorporating Snake Plants into Your Bedroom
If you’re considering adding a snake plant to your bedroom, here are some tips to maximize the benefits and minimize potential risks:
- Choose the right size plant for your space. A larger plant will have a greater impact on air quality, but ensure it doesn’t overcrowd the room.
