A lot of people still believe you should not have plants in a bedroom, fearing they will starve you of oxygen at night. False idea: a plant’s oxygen consumption in a bedroom is negligible. Better, a few species actually keep producing oxygen at night thanks to a special metabolism. Here are seven worth picking.
What to look for
- Low-allergen plants (little or no pollen).
- Species tolerant of typical bedroom light.
- Not strongly fragrant (gardenia, jasmine), which can disturb sleep.
- Not heavy transpirers (too much humidity in a sleeping room).
1. Snake plant, the champion
The snake plant (Dracaena trifasciata) is the bedroom plant. Its CAM metabolism opens its stomata at night, releasing oxygen while you sleep.
Tolerates dim light, dry air, missed waterings. Truly the simplest option.
2. Aloe vera
Like snake plants, aloe vera is a succulent with CAM metabolism. It releases oxygen at night. Bonus, its gel works on minor burns.
Bright light ideally (near a window), spaced waterings.
3. Peace lily
Spathiphyllum tolerates dim light and cleans the air by absorbing formaldehyde and ammonia. Its elegant white blooms add a sense of calm to the room.
Keep substrate slightly moist. Toxic to cats if ingested, place high if needed.
4. Golden Pothos
Pothos absorbs volatile organic compounds (paint, new furniture) and grows anywhere, even in a dim bedroom. Its trailing shape softens the look of the room visually.
5. Potted lavender
For the calming side, potted lavender is interesting. Its scent has documented relaxing effects and helps with falling asleep. Needs a lot of light, place near a window.
6. Spider plant
Tolerates everything, captures formaldehyde, makes pups. Variegated forms available. Low allergen.
7. Aglaonema
For dim bedrooms that still want color. Red, pink, or silver varieties. Tolerates neglect, indifferent to ambient humidity.
How many plants to add
Simple rule: never more than you can take care of. Three to five plants in a standard bedroom is plenty.
Practical tips:
- One plant per square meter at most on the floor.
- Hang or use shelves to keep the surfaces clear.
- Air the bedroom 10 minutes in the morning, like every room.
What to avoid in a bedroom
- Strongly scented plants (gardenia, jasmine, Mexican orange): can disrupt sleep.
- Pollen plants (seasonal flowering plants): allergy risk.
- Spiky cacti: safety hazard if you get up at night.
- Heavy transpirers (Areca, large ferns): add humidity, not ideal in an already humid bedroom.
The closed-bedroom myth
A plant in a closed bedroom at night does not make the air dangerous. Becoming problematic would require dozens of plants in a sealed room, which never happens in normal conditions. So sleep peacefully with your snake plants and pothos.
Tracking with Plenova
Plenova helps build a bedroom selection matched to your light exposure and pet situation. The app clearly flags non-toxic species and the ones to avoid if a cat sleeps on the bed.
A bedroom with a few green plants is a slightly better night’s sleep without realizing it, and a wake-up with a bit more life around you.
Your plants deserve more than a random app
Plenova names your plant, spots what is wrong, and reminds you of the right action at the right time.
