Why Is My House So Humid and How to Deal With It

high humidity in a house

Dealing with high humidity in a house is not easy – it can be very uncomfortable and stressful. You’re constantly feeling hot, and you’re sweating profusely. Your entire body is sticky, and your heart is beating way too fast.

In the worst scenario case, too much moisture can be suffocating and introduce troubles with breathing. It’s important to maintain ideal humidity levels indoors to avoid complications with your health, to prevent irritability, and stay comfortable.

Signs You Have a Humidity Problem in Your House

You’re obviously not gonna be walking around with a hygrometer, so how can you tell if it’s too humid?

One of the most obvious signs that it’s too humid inside your house is persistent sweating. Constantly feeling sticky can make you very irritable. Sweat can’t evaporate because of the high moisture content in a humid room, so you gain no relief.

Another evident indicator of excess humidity indoors is being unable to sleep well at night. The National Sleep Foundation talks about how humidity impacts sleep. They state that air that is too dry or too moist can disrupt sleeping patterns negatively.

A more serious and concerning sign of a humidity problem in your home is experiencing trouble with breathing. This has the potential to lead to symptoms of asthma.

Humid air triggers certain nerves in the lungs that constrict your airways. It also turns the air inert, which traps allergens. This can cause serious respiratory issues.

Is Too Much Humidity Hurting Your Health?

The renowned Greek physician, Hippocrates, once said, “everything in excess is opposed to nature.” This can be applied to humidity. High indoor humidity levels can cause several health problems.

You’re dependent on the air to get rid of sweat on your body, so when you can’t – you’re prone to dehydration and even heat strokes. In a study, it was found that respiratory infections were less common in people who spent time in an environment with moderate humidity, as opposed to high/low levels.

It can have both direct and indirect effects on your health. High moisture content in the air is a paradise for bacteria and viruses. If you have allergies then excessive humidity is deadly.

What if you’re an asthmatic? It gets even worse because dust particles thrive in these conditions. Since bacteria thrive in such settings, so does mold. Mold can be an irritant to your eyes, nose, and even lungs.

What Causes High Humidity in Your House?

It’s time to finally break it down. What exactly is causing these high humidity levels in your home? Let’s go through the four primary causes of excess humidity and discuss these factors.

Showering

Most of us love steaming hot showers, but, unfortunately, they contribute to a humid environment. When water vapor is hot, the air can hold more moisture. It can also cause a mold problem, which could spread.

As previously mentioned, mold is a big no-no and causes serious health problems. You should try to turn down the heat. Reduce steam emissions by taking cold showers, which are also good for your skin and hair.

Poor Ventilation

This one is pretty self-explanatory. Air quality in your house is directly affected by how good your ventilation is. The air that’s in your home is going to become stale and polluted if it isn’t properly circulated.

Humidity levels keep on rising when your ventilation system isn’t doing its job. For example, assume you keep on taking those hot showers we just talked about. The humidity they generate isn’t being ventilated.

Try to make sure there’s good ventilation in your home. This will keep the air fresh and will prevent the build-up of moisture.

Location

Yes, you can change the environment inside your home, but you can’t change the things you can’t control. Some regions are hotter than others, and so, more humid, especially in summer.

Warmer air contains more moisture, so places with a coastal climate have higher relative humidity. This also applies to places that get a lot of rainfall. Unfortunately, there are not many remedies for this, besides focusing on your indoor environment.

Rising Damp

A less common but way more serious cause of humidity is rising dampness. This creeps up on your walls and is a serious health hazard. It can cause respiratory infections, asthma, and – you guessed it – mold.

Health issues aside, rising damp can also damage the structure of your home too. It’s important to contact professionals to fix this problem.

Drying Your Laundry Indoors

This is pretty apparent, but drying your laundry indoors is gonna make your home humid. These wet clothes can let out up to 2.5 liters of water.

This volume of water won’t just disappear and you’ll see it come through when the house suddenly feels stuffier. Invest in a clothesline and dry your laundry outside.

How to Decrease Moisture and Humidity in the Home?

humidity level

According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers, the humidity level in your home shouldn’t exceed 65 percent. An ideal range goes from about 30-50%. In winter, this standard is lowered to 30-40%.

So, the question arises – what steps should you take to reduce humidity in your home?

Air Conditioning Units

Getting an AC unit installed inside the premises is the ideal way to reduce humidity. The way an air conditioning system works is it emits cool air while extracting warmer air out of the environment. They can adjust humidity as well, in addition to temperature.

Take a Cold Shower

As mentioned before, we’re all fans of hot showers. We aren’t asking you to bathe in ice. But just the difference of a few degrees can reduce how much steam your shower emits. In the long run, this helps lower humidity levels.

Ventilate

Refreshing the air in your home is critical. Just opening one window can do wonders with air circulation. So just do it. Open that window. It’s not gonna hurt anyone.

And try to use the exhaust fans installed in your kitchen and bathroom. They’re there for a reason, so let them do their job.

Plants

This one is a little paradoxical. On the one hand, house plants can boost humidity levels. On the other, some plants absorb moisture.

The water you give plants eventually evaporates into the air hence humidity levels see a rise. But, some plants can actually absorb moisture. This can help reduce humidity.

A couple of plants that absorb humidity are: Reed Palm, Boston Fern, Peace Lily, English Ivy.

Consider getting some of these for your windowsill to help control the humidity in your house.

Get a Dehumidifier

Last but not least: a dehumidifier is a good solution. They’re the holy grail of removing moisture from the environment.

Drying your laundry indoors? Put a dehumidifier next to it. Don’t wanna sacrifice your steaming showers? Just get a dehumidifier.

Live in a really humid region? Anything that’s causing humidity? You should try a dehumidifier.

The way a dehumidifier works is that it draws hot air into itself using a fan. Dehumidifiers contain refrigerated coils inside them so once the warm air hits them, it condenses. These water drops are fed into a storage tanker attached to the machine.

Cool and dry air is then emitted into your home. Some dehumidifiers also come with humidity meters. And you can actually choose the percentage of humidity you desire in the environment! Oh, and, don’t wanna pay insane cooling bills for your air conditioner? Dehumidifier.

Final Verdict

So, in conclusion, high humidity levels should be a concern. It can have a lot of consequences, to your health and to your home. Excessive humidity is a killer to those with allergies or asthma. It promotes respiratory illnesses.

You should consider one of the above-mentioned methods of reducing humidity if you’re struggling with this issue yourself.
