The sensation of cold and humidity has surprised Peruvians in recent days, especially during the early mornings. According to the National Meteorology and Hydrology Service (Senamhi), low temperatures will persist, affecting mostly the eastern districts of Lima, where humidity will reach peaks of 96% to 98%.

“Due to the weather conditions of the city, humidity is an important source for the development of mold. These spores have a very lightweight and spread easily in the air until they reach the lungs of humans”, explains Javier Jáuregui, Pulmonologist at the Clínica Ricardo Palma.

Consequently, mold can cause various conditions in the body such as allergic rhinitis, bronchospasm, sinusitis, allergic conjunctivitis, and, in the worst case, hypersensitivity pneumonitis.

Likewise, the specialist explains that there are two types of fungi in the environment: the indoor ones, such as the aspergillus fungus, and the outdoor ones, such as the Alternaria fungus. “Both can affect 10% of the Peruvian population that has some kind of sensitivity to any allergen”, warns Jáuregui.

Preventive measures at home

Although the sensation of humidity at home is inevitable, it is important to follow certain guidelines to avoid the appearance of fungus and mold in the rooms. Therefore, follow the tips below:

• Before deep cleaning use a face mask, preferably an N95.
• After using the bath or shower, dry every part of the room and make sure not to leave the faucet half-open.
• Remove dust and dirt from the most remote areas of your home, such as under the bed and behind desks and furniture.
• Despite the cold, regularly ventilate the main rooms and leave the doors open. You can take advantage of sunny days.
• Avoid having stored shoes, newspapers, and accumulated books at home. If you are not going to use them, it is better to get rid of them.

Finally, the specialist highlights that it is important to learn to live with humidity since it is part of Lima every year. However, if you have some respiratory problems, the best alternative is to purchase a dehumidifier to keep the humidity at home between 40 and 50%.
