There are several high humidity in house health problems that you should be aware of.
Humidity is the moisture content in the air. You can use a hygrometer to find out whether your indoor humidity is too high.
In another article, we said that 70 percent humidity outside is high. It feels even higher indoors. The recommended relative humidity level is 35 to 55 percent. If it is higher than that, you will be uncomfortable in that room.
High humidity in house health problems
Briefly, here are the main health problems that you will encounter as a result of high humidity at home:
- More allergens
- More bacteria and viruses
- It can trigger asthmatic attacks
- More airborne contaminants
- Throws your body mechanics into whack
As you can see, there is enough cause for worry about when you have high humidity indoors. But just what indoor humidity is too high? 30 to 55 percent indoor humidity is comfortable. 40 to 60 percent is okay, but anything above 60 percent is too high.
In more detail, here are the effects of high humidity on health:
1. More allergens thrive indoors
When the indoor humidity rises, indoor allergens thrive. For instance, dust mites thrive in high humidity environments. And so do fungi.
These two are some of the most sinister indoor allergens. Fungi cause many illnesses such as candida auris, aspergillosis, candidiasis, fungal infection of the eyes and others.
On the other hand, the microscopic-sized dust mites do not cause any illness to healthy humans. However, for people with certain allergies, dust mites can trigger certain reactions.
2. More bacteria and viruses
Humid air feels warmer and heavier than dry air. This has many disadvantages. For instance, when the air is too humid, bacteria and viruses tend to float longer before they fall to the ground.
Thus, chances of inhaling these disease-causing agents are very high. Also, bacteria and viruses tend to thrive and breed faster in humidity levels that exceed 60 percent.
When there are more than three people gathered in a small space such as an office or a car, a person with a cold can infect all of the others.
When the air is drier, the pathogens are not likely to remain afloat for long. They fall to the ground or they settle on other surfaces. They would be harder to inhale.
Prevent your indoor air getting to dangerous humidity levels. You can do this by using a dehumidifier or by using natural means to lower indoor humidity.
3. High humidity triggers asthmatic attacks
When the indoor air is too dry, it can trigger asthmatic attacks especially if there is dust. On the same note, if the air is too humid, mold spores and fungi trigger asthmatic attacks.
Mold spores and fungi are not things that you will see with your eyes. Rather, they float in the air, you inhale them and they aggravate respiratory illnesses.
If you suffer from asthma, if you inhale fungi and mold spores, they will trigger asthmatic attacks. They thrive in humid conditions that are higher than 60 percent.
Always look for signs of mold infestation in your home. Check the dark and humid spaces in the bathroom, kitchen and the basement. If you see dark spots on the ceiling, under the kitchen sinks and other dark spaces, you have mold.
If you have a whole house dehumidifier, it can also cause mold spores and fungi if it is not well maintained. Ducted systems are notorious for causing fungi to find their way into your indoor space.
4. More chemicals and other contaminants in your air
High humidity leads to the release of more chemical air contaminants. For instance, you are more likely to experience the smell of formaldehyde when the humidity is high rather than when it is low.
Some of the sources of formaldehyde include the adhesives and glues that manufacturers use to make furniture. This chemical gas also comes from new building material, clothes and bedding, carpets and other sources.
Since some of these sources such as bedding and clothing contain minimal amounts of formaldehyde that is added to preserve the fibers, they may off-gas more in humid air than in drier air.
Some of the ill effects of formaldehyde include eye and throat irritation, skin rashes, breathlessness and many more.
5. Throws your body mechanics into whack
In another article, we discussed the effects of high humidity on your body. There are several of them!
Indoor humidity and health are related directly. Most importantly, when your body senses high humidity, a few things happen.
First, you will experience a lot of clamminess on your skin. The reason for this is that the high humidity makes the air feel warmer.
To cool down, you start sweating. But this sweat does not evaporate. Rather, it remains on the skin, making you more damp and more uncomfortable.
When you sweat, you are likely to experience dehydration. Thus, you have to drink more water to stay hydrated. If you do not lower the humidity, you keep sweating more until your clothes soak through.

What causes high humidity in a house?
Many things can cause high humidity in a house. First, if you live in a humid place like Florida, the humidity will be naturally high almost throughout the year.
Also, cooking, washing clothes and flooding increase moisture content in the air. This is why you should always run a dehumidifier. Some indoor plants can also make your air more humid.
If you live in Seattle, you definitely need to buy a dehumidifier to tame the runaway moisture content.
What is dangerously high indoor humidity?
30 to 50 percent humidity level is comfortable while 35 to 60 percent is okay. However, anything above 60 percent is too high humidity and it can make mold, dust mites, fungi and other indoor allergens thrive. At 80 percent, that is dangerous because you might even have problems breathing properly.
How can I lower the humidity in my house without a dehumidifier?
You can buy indoor plants that help to lower humidity. Also, you can dry your clothes outside rather than drying them inside. You can also run your air conditioning because it helps.
