Harmful of High Indoor Humidity for Humans

High indoor humidity can have various harmful effects on human health. When the indoor humidity level is too high, it creates a breeding ground for molds, mildews, and other microorganisms, which can cause respiratory problems such as allergies, asthma, and other respiratory diseases. These microorganisms can also produce unpleasant odors that can affect the overall air quality in the room.

Excessive humidity can also make the indoor environment feel uncomfortable and sticky, making it difficult to concentrate or get good quality sleep. It can cause skin irritation, itchiness, and rashes, especially in people with sensitive skin. In addition, high humidity levels can promote the growth of dust mites, which can trigger allergic reactions.

Here are some methods to reduce indoor humidity:

  1. Use air conditioning or a dehumidifier: Air conditioning or a dehumidifier can reduce the humidity in the air. Setting the air conditioning or dehumidifier to the appropriate humidity level, usually around 40-50%, can keep the indoor air relatively dry.

  2. Increase ventilation: Increasing air flow by opening doors and windows, using exhaust fans, or using exhaust fans in bathrooms and kitchens can help remove moisture from indoor air.

  3. Reduce sources of water: Reduce the frequency of watering indoor plants and minimize the evaporation and accumulation of water indoors to lower indoor humidity.

  4. Use a dehumidifying agent: A dehumidifying agent can be used in humid areas such as closets, kitchens, and bathrooms to help absorb moisture from the air.

  5. Keep indoor areas clean: Keeping indoor areas clean can prevent the growth of mold and bacteria, and can also reduce indoor humidity.

These methods can be used individually or in combination, and selecting the appropriate method based on the specific situation can effectively reduce indoor humidity. However, it is important to note that if the humidity is too low, it can cause dry skin, eye discomfort, and other problems, so it is not advisable to lower the humidity too much.
