In modern life, we spend most of our time in indoor environments. Therefore, indoor air quality directly affects our health and well-being.

However, with the arrival of winter, more and more people are asking: Why do I always feel drowsy indoors lately?

In fact, during winter, many people choose to keep doors and windows tightly closed for warmth, leading to CO2 accumulation indoors. Research shows that when the indoor CO2 concentration reaches 1000ppm, the human body will experience symptoms such as lack of concentration and slow reaction. When the concentration reaches 2000ppm, symptoms like dizziness and nausea appear. At 5000ppm, one may experience difficulty breathing or even coma.

Besides making people drowsy, indoor CO2 accumulation also impacts the human body in the following ways:

● Reduced work efficiency: In high CO2 environments, people feel fatigued and unable to focus, thereby lowering productivity.

● Affected sleep quality: High CO2 levels can disrupt sleep, leading to light sleep and frequent waking.

● Increased disease risk: Long-term exposure to high CO2 levels increases the risk of cardiovascular and respiratory diseases.

Using CO2 sensors is an effective method to monitor and control indoor CO2 levels. These sensors can monitor concentration in real-time and sound an alarm when thresholds are exceeded. This allows occupants to take necessary actions, such as opening windows or using air purification systems, to improve air quality.

It is worth noting that good building design and air management systems are also vital. For example, regular ventilation and effective air circulation systems can significantly reduce CO2 buildup and enhance overall air quality.

In conclusion, indoor CO2 accumulation indeed affects daily life, especially in confined or poorly ventilated spaces. By effectively monitoring and managing CO2 levels, combined with proper ventilation and purification, we can reduce negative impacts and create a healthier environment.
