CO2

Here are two lesser-known but important health facts about why monitoring CO2 levels in your home is essential:

1. CO2 Build-Up Can Affect Cognitive Function: Elevated indoor CO2 levels, even at concentrations previously thought to be safe (e.g., 1,000–2,500 ppm), can impair cognitive functions like decision-making, focus, and memory. Studies have shown that when CO2 levels rise, the brain receives less oxygen, which can lead to reduced mental performance, sluggishness, and difficulty concentrating, especially in poorly ventilated spaces.
2. CO2 Can Disrupt Sleep Quality: High CO2 levels, especially in bedrooms, can negatively impact sleep. Increased CO2 reduces the oxygen availability in the air, causing shallow breathing, restlessness, and frequent waking during the night. This can lead to poor sleep quality, which in turn can affect overall health, immune function, and mental well-being over time. Keeping CO2 levels in check by ensuring proper ventilation can significantly improve sleep and overall health.
