Myth Busted: Houseplants Don't Steal Oxygen at Night

Sleeping with 5 plants (Spider Plant, Swedish Ivy, Calla Lily, etc.) is perfectly safe.

The Science

• Day: Photosynthesis > Respiration → net O₂ production.
• Night: Respiration only → tiny CO₂ release (negligible vs. human breath).
• 24-hr net: Plants remove CO₂, add O₂, filter VOCs.

Benefits

• Air purification (formaldehyde, benzene).
• Humidity increase.
• Psychological well-being.

More plants = healthier air. Sleep soundly.
