What effect do VOCs typically have on indoor air quality?

Volatile Organic Compounds (VOCs) are chemicals that can evaporate at room temperature and are commonly found in many household products, such as paints, solvents, cleaning agents, and air fresheners. When released into the indoor environment, VOCs can significantly degrade indoor air quality and lead to health issues.

Exposure to high levels of VOCs can cause a range of health problems, including headaches, dizziness, respiratory irritation, and in some cases, long-term effects such as damage to the liver, kidneys, or central nervous system. Certain VOCs are also known carcinogens, which further emphasizes their potential danger when present in indoor settings.

In contrast, the other options do not accurately represent the impact of VOCs. They do not improve air circulation, have a notable negative effect on health, and they do not enhance natural light. Therefore, the understanding of VOCs' negative implications on health is critical in managing and improving indoor air quality.
