Often striking with its upright and bold green leaves, the Snake Plant, or more colloquially known as the Mother-in-law’s Tongue, is more than just an aesthetic addition to your home. One of the standout features of this plant is its remarkable air-purifying qualities. 

According to a pivotal study by NASA, the Snake Plant stands out for its ability to filter indoor air pollutants like benzene, formaldehyde, and xylene. 

But what truly sets it apart, especially in the context of sleep, is its unique ability to perform photosynthesis at night. 

Unlike most plants which uptake CO2 and release oxygen during the day, the Snake Plant defies this norm by releasing oxygen at nighttime. This means that having this plant in your bedroom could potentially improve air quality, making the environment more conducive for a deep, rejuvenating sleep.

3. Aloe Vera

Aloe Vera, with its succulent leaves and gel-filled interior, has long been celebrated for its myriad health benefits, especially in skincare. The gel extracted from its leaves is renowned for its soothing properties, alleviating sunburn, hydrating skin, and even accelerating wound healing. 

However, what’s lesser-known is its commendable role in promoting sleep. Much like the Snake Plant, Aloe Vera is adept at releasing oxygen during the night, aiding in improving indoor air quality and thus fostering a more sleep-friendly environment. 

It was also listed in NASA’s research, among plants that removed formaldehyde from the environment.

Besides its health benefits, homeowners and plant enthusiasts laud Aloe Vera for another reason – its low maintenance. 

Thriving even with minimal care, it requires infrequent watering and is adaptable to various indoor conditions, making it a perfect bedside companion for those who seek both beauty and function without much fuss.

Maintenance and Nurture

Known for its hardiness, the Snake Plant demands little attention. It can tolerate low light conditions and infrequent watering. For those of us with busy lifestyles or less-than-green thumbs, it’s an ideal choice.


This plant doesn’t just survive; it thrives in a variety of conditions. Whether you occasionally forget to water it or it’s placed in a less-than-ideal spot in your home, the Snake Plant remains robust.

Unlike most plants that produce oxygen during the day, the Snake Plant has a unique ability to release oxygen during the nighttime, enhancing the air quality in your bedroom when you need it the most.

Greater Ability to Filter Toxins

The Snake Plant’s (Mother-in-law tongue), scientifically known as Dracaena trifasciata, has been spotlighted for its remarkable air-purifying capabilities. As substantiated by NASA’s research titled ‘INTERIOR LANDSCAPE PLANTS FOR INDOOR AIR POLLUTION ABATEMENT’ in 1989, this resilient plant is particularly adept at processing harmful indoor pollutants such as Benzene, Formaldehyde, and Trichloroethylene (TCE).

While all the plants on our list offer wonderful benefits for sleep, the Snake Plant’s combination of low maintenance, resilience, and its exceptional ability to improve nighttime air quality arguably puts it at the pinnacle. For those looking to make a single green addition to their bedroom for better sleep, this might just be your top pick.

And if you’re just embarking on this green journey, don’t hesitate to ask questions or share your anticipations. After all, sleep isn’t just a necessity; it’s an experience. And what better way to enhance it than with a touch of nature.


Which plants release oxygen at night?

Many plants photosynthesize by taking in carbon dioxide and releasing oxygen during the day. However, a select group of plants utilizes a process called CAM (Crassulacean Acid Metabolism) photosynthesis, which allows them to intake CO2 during the night and release oxygen. Some plants that release oxygen at night include:

1. Aloe Vera: Apart from its numerous health benefits, it’s an excellent oxygen producer at night.
2. Snake Plant (Mother-in-law’s Tongue): Highly recommended for improving indoor air quality, it releases oxygen both day and night.
3. Orchids: Unlike many plants, orchids can produce oxygen during the night. They’re also beautiful additions to any room.
4. Succulents: These hardy plants continue to produce oxygen throughout the night.
5. Cacti: Just like succulents, cacti utilize CAM photosynthesis, making them nighttime oxygen producers.

Are there any indoor plants I should avoid due to allergies or toxicity?

Yes, while many indoor plants are beneficial, some can be harmful, especially if ingested. Plants like Poinsettias, Oleander, and certain types of lilies can be toxic to pets and humans. If you have allergies, it’s essential to research and select hypoallergenic plants.

Do plants give off CO2 at night, is it harmful?

Yes, plants undergo a process called respiration both day and night. During respiration, plants take in oxygen and give off carbon dioxide (CO2), similar to the way animals breathe. This process is distinct from photosynthesis, which only happens when there’s light. During photosynthesis, plants absorb carbon dioxide and release oxygen. However, the amount of CO2 they release at night is minimal, especially when compared to the oxygen output during the day for many plants. In the grand scheme of indoor air quality, the CO2 released at night by plants is inconsequential and not harmful to humans.

How often should I water indoor plants?

The frequency of watering indoor plants varies depending on the type of plant, its specific needs, and the environment it’s in. Generally, you should water when the top 1-2 inches of soil feels dry to the touch. Overwatering is a common mistake, as many plants prefer to dry out a bit between waterings. It’s essential to ensure that your plant pot has drainage holes to prevent water from sitting at the bottom, which can lead to root rot. Always research your specific plant’s watering requirements and adjust based on the humidity and light conditions of your space.

Do indoor plants need direct sunlight?

Not all indoor plants require direct sunlight; in fact, many thrive in low to indirect light conditions. While some plants, like succulents and cacti, might prefer brighter, direct light, others like snake plants, pothos, and ZZ plants can do well in lower light conditions. When choosing plants for your space, it’s crucial to understand the light conditions they prefer and to place them in a suitable spot in your home. If a plant is not receiving adequate light, it may become leggy or have stunted growth. On the other hand, too much direct light can scorch and damage the leaves.
