Long dismissed as an old-fashioned houseplant, the Sansevieria—also known as the snake plant or mother-in-law’s tongue—is making a strong comeback today.
And not just because it’s low-maintenance. What many people don’t realize is that this unassuming plant hides remarkable benefits that can improve your air quality, your sleep, your energy levels—and even your overall health.
Ready to rediscover a plant you thought you already knew? Here’s why every room in your home could benefit from having one.
A plant endorsed by NASA
In a well-known study on indoor air quality, NASA ranked the Sansevieria among the top air-purifying plants.
What sets it apart? Unlike most plants that stop producing oxygen at night, the Sansevieria continues to release oxygen 24 hours a day thanks to its CAM metabolism. It’s an ideal plant for bedrooms!
The little-known benefits of Sansevieria for body and mind
1. A natural shield against indoor pollution
Mother-in-law’s tongue effectively filters:
- Formaldehyde (found in furniture, fabrics, adhesives)
- Benzene (household cleaners, plastics)
- Xylene and toluene (paints, solvents, varnishes)
The result: cleaner indoor air—silently, effortlessly, and without the need for maintenance.

2. Better sleep? Yes, it’s possible.
At night, this plant continues releasing oxygen. Many people report falling asleep faster and enjoying more restful nights when a Sansevieria is placed in their bedroom. Its natural transpiration also helps regulate humidity levels, which may reduce snoring, sore throats, and discomfort during the night.
3. A potential barrier against digital fatigue
Although not yet scientifically proven, some people say they experience less mental and visual fatigue when several Sansevierias are placed in their workspace. Between air purification and its calming presence, it may make a noticeable difference.
