Mold allergy occurs when the immune system reacts to mold spores in the environment. These tiny fungi thrive in damp areas, such as basements, bathrooms, and outdoors. Common symptoms include sneezing, runny nose, itchy eyes, and skin rashes. People with mold allergies may experience more severe reactions, especially those with asthma or other respiratory conditions. To manage mold allergies, it is essential to reduce exposure by keeping living spaces dry and well-ventilated. In some cases, over-the-counter antihistamines or prescribed medications can help alleviate symptoms.
