Poor indoor air can cause frequent awakenings, reduced sleep quality, and next-day fatigue.
A level below 1,000 ppm is considered good. Levels above 1,200 ppm can impair sleep and concentration.
It’s recommended to air out the room at least twice daily — and always before bedtime — to reduce CO₂ and humidity.
Yes, some plants absorb CO₂ and release oxygen, but their effect is limited compared to proper ventilation.
Common signs include morning headaches, stuffy air, and fatigue. A CO₂ indicator like Birdie can help monitor air quality.
Between 16–18 °C (60–65 °F) is optimal. Combined with good ventilation, this significantly improves indoor air quality.
