Humidity has a number of benefits, like lowering the risk of spreading airborne illnesses. However, too much humidity in your apartment can cause issues. Excess humidity can encourage mold growth, create health problems, and even lead to heat exhaustion. If the air in your apartment is thick and muggy, finding out the cause can help you to swiftly identify and enact a solution so you’ll reach the ideal indoor humidity level in no time.
How do I know if my apartment is too humid?
Your apartment may be too humid if you experience these signs:
- The air feels stale: An excess of humidity can typically result in inhibited airflow, leaving your space feeling thick and still. This can also encourage the presence of indoor air pollutants, such as dust mites. If the air in your home feels stale, try using an air purifier to freshen the environment.
- Windows or other surfaces have condensation: Surfaces such as pipes, mirrors, and windows collect condensation in the presence of humidity. To see if the moisture has spread from these surfaces, feel the surrounding areas for dampness. Surfaces that remain damp can cause long-term issues.
- There are stains on your walls or ceiling: Extraneous moisture can cause discoloration. While often hard to spot, this can be a sure sign of too much humidity. In addition, excess moisture in the air can cause floorboards to creak and stucco to crumble.
- Your space smells musty or mildewy: Excessive humidity can often encourage mold. To check if your home smells like mold or mildew, take a deep breath right upon entering the space. After you come in from breathing fresh air, any unusual odors will be easier to detect.
- You’re experiencing allergy-like symptoms: Both humidity and the mold it can cause can manifest in physical symptoms. If you, a family member, or a roommate has been suffering from excessive headaches, shortness of breath, or a persistent cough, it may be a result of humidity. Additional symptoms of exposure to mold include blocked nasal passages and irritation of the eyes, skin, or throat.
- You constantly feel exhausted: In addition to feeling the symptoms listed above, those who live in homes with excessive humidity may experience dehydration, which can result in heat exhaustion. This occurs because the moisture in the area traps your sweat against your skin, keeping it from naturally evaporating. While you work to dehumidify your home, drink lots of water, and avoid excessive physical activity.
If you’ve checked for these signs of humidity and want a second opinion, humidity monitors are also available for a relatively low cost. You can use a humidity monitor to check the moisture in your home against ideal humidity levels. Ideal indoor humidity levels are anywhere between 40% and 60%, with the lower percentage being more likely in the winter and the upper range occurring in the summer.
Why is my apartment so humid?
Potential sources of excess moisture include:
- Leaks: The most obvious cause of humidity, leaks (especially small leaks) can go unnoticed and wreak havoc in your apartment. Bring any leaks to the attention of your landlord so they can repair them as quickly as possible.
- Poor ventilation: Maintaining a proper level of airflow within your home helps counteract the release of moisture that occurs when you do common activities such as cooking, cleaning, and bathing. Poor ventilation can typically result from a lack of fans or windows.
How to deal with excess humidity in your apartment
Excess humidity in your apartment can lead to discomfort, mold growth, and potential health issues. Follow these steps to effectively manage and reduce humidity levels:
- Identify the source
Determine the source of excess humidity. Common culprits include cooking, showering, and inadequate ventilation. Addressing the root cause is essential for long-term humidity control.
- Improve ventilation
Proper ventilation is key to reducing humidity. Use exhaust fans in bathrooms and the kitchen when cooking or showering. Open windows on dry days to allow fresh air circulation.
- Use dehumidifiers
Invest in a dehumidifier to remove excess moisture from the air. Place it in areas prone to high humidity, such as bathrooms, basements, or closets. Choose a dehumidifier size suitable for your apartment’s square footage.
- Repair leaks
Fix any leaks in pipes, roofs, or windows promptly. Water intrusion can lead to increased humidity and mold growth.
- Monitor indoor plants
Indoor plants release moisture into the air through a process called transpiration. Limit the number of plants or group them together to reduce their impact on indoor humidity.
- Use air conditioning
Air conditioning not only cools the air but also removes excess moisture. Set your AC to a comfortable temperature and use the “dry” or “dehumidify” mode if available.
- Seal windows and doors
Check for drafts around windows and doors. Properly sealing these openings can prevent humid outdoor air from entering your apartment.
- Use absorbents
Place moisture-absorbing materials like silica gel packets or charcoal bags in areas prone to high humidity, such as closets or storage spaces.
- Keep temperatures consistent
Fluctuating temperatures can lead to condensation, increasing indoor humidity. Maintain a consistent temperature to prevent this.
- Monitor humidity levels
Use a hygrometer to monitor indoor humidity levels. Ideal indoor humidity ranges from 30% to 50%. Adjust your efforts based on the readings.
If you find that humidity continues to be an issue in your home, there are several long-term solutions you can try as well. After trying the solutions above, consider speaking with your landlord about:
- Caulking: By lining surfaces that constantly experience moisture in your apartment, you’re essentially waterproofing your space. You’ll particularly want to check caulking around areas such as sinks, toilets, tubs, and faucets.
- Weatherstripping: The same logic that makes caulking advantageous also applies to the exterior of your apartment. Weatherstripping, usually done around doors and windows, helps to seal your home against humidity and prevent air-conditioned air from escaping. By weatherstripping your apartment, you may also be able to save money on your electric bill.
- Insulation: Similar to weatherstripping, ensuring your apartment is properly insulated can also help to keep heat from escaping and humidity from entering.
Final thoughts
The ideal indoor humidity is anywhere within the 40% to 60% range. Humidity in this rance can be easier on your respiratory system, banish allergens, promote better sleep, and benefit your health and well-being. The sooner you’re able to get your humidity within ideal levels, the better you’ll feel, and the safer your home will be.
