Final answer:
Excessive ventilation can cause hyperventilation, leading to symptoms like lightheadedness or fainting. Moreover, when dealing with products or appliances that release pollutants, excessive ventilation can heighten exposure to these harmful substances.
Explanation:
The caution against excessive ventilation, likely refers to the potential dangers of hyperventilation and exposure to harmful pollutants. Hyperventilation is an increased rate of breathing that leads to abnormally low blood carbon dioxide levels and elevated blood pH, which can result in side effects such as lightheadedness, tingling sensations, and fainting. On the other hand, when using products or appliances that may release pollutants into the indoor air, ventilation is necessary to remove harmful substances and maintain air quality. However, if the ventilation becomes excessive, it can increase the dispersal of pollutants, hence, exacerbating exposure and potential risks.
