Is it safe to sleep in a room with mold on the wall?

It is not safe to sleep in a room with mold on the wall because mold releases spores that can affect indoor air quality and cause health problems. Breathing in these spores may lead to allergic reactions, coughing, nasal congestion, or irritation of the eyes and throat. People with asthma, weakened immune systems, or respiratory issues are at higher risk of experiencing more severe symptoms. Prolonged exposure can worsen existing conditions or cause fatigue and breathing discomfort. The affected area should be cleaned properly, and the moisture source removed before the room is considered safe for sleeping again.
