Have you noticed that your hair frizzes up in your home during the summer when 80 degrees feels more like 100 degrees? Well, your home may have too much humidity in it. Humidity is the amount of water that’s in the air. High humidity can make you feel sluggish and sweat faster. If you have this problem, this means you need to reduce humidity in your home.

You may have some questions: How humid should your home be? Why does it seem to be more humid in the summer? What should you do if you do feel like the air in your home is too humid? What are the most humid states in the summer? 

Get all the answers to these questions and more in this article! Here is everything you need to know about how to reduce humidity in house in summer.

What is the best humidity level for home in summer?

It’s important to achieve an ideal indoor humidity level for your home during the summer. Excessive humidity can do a lot more damage than just making your hair frizzy. Excessive moisture can damage and warp the wood in your home. As well, it can help create the perfect breeding conditions for mold, too. This can make your home less attractive, and it may even require expensive repairs.

Breathing in too much moisture can be bad for your health as well. In some cases, this can result in respiratory issues. For these reasons, you need to be able to control the level of humidity in your home. However, what should the humidity of your home be during the summer? Fortunately, there is an exact answer to this question.

The Environmental Protection Agency (EPA) has done the research. They have come to the conclusion that your home interior should have humidity levels that range between 30% and 50%. This is the sweet spot in which you will feel the most comfortable. Within this range, you can adjust levels according to your preference. However, indoor humidity levels should never exceed 60%. At this level, you may start to see potential damage done to your home.

How can you tell if your home is at the ideal indoor humidity in summer?

A device called a hygrometer is used to provide a digital reading of how humid your home is. It also has other features, such as giving you the temperature. For best results, try ThermoPro Indoor Hygrometers, such as the TP357 Digital Hygrometer to get an accurate reading every time. Other types of thermometers and AC units can give you this information as well.

What is ideal summer indoor humidity? 

If you don’t have a device to tell you exactly what the humidity is, you can always tell by how you feel when you’re inside your home. 

It should be low enough so that the air doesn’t feel thick and frizz your hair. Simply put, if the air in your home is too humid, you’ll know it by feeling it.

Why is the humidity higher during the summer?

how to decrease humidity in house in summer

Humidity levels are always higher in the summer. We usually associate humidity with hot weather and the summer months. Why is this? Ultimately, humidity is higher in the summer because warm air holds more moisture. In fact, air that is 68 degrees can hold 10 times more water than air that is only 32 degrees. When outside air reaches its full capacity for moisture, it starts to rain to purge its excess moisture.

Since warmer air can carry more water, it can hold more moisture. This is what makes the air feel physically thicker. Under this heaviness, physical activity can feel more difficult. You will also start to sweat extraordinarily quickly. If you want to avoid outside humidity during the summer, it’s best to go outside later in the day. Humidity is at its peak in the morning. People who wake up and go for a run in the morning might want to consider going after work or after dinner instead.

How to reduce humidity in house in summer?

It’s one thing to understand that there is humidity in your home; it’s another thing to do something about it. When you know how to reduce summer humidity in your home, you and your family will become a lot happier and healthier. 

Here are just some of the ways you can reduce summer humidity in your home:

1. Buy a dehumidifier

The most obvious way to get the moisture out of your home’s air is to use a dehumidifier. This is a device specifically designed to extract water out of the air and reduce humidity.

Here’s how it works: Air goes through the refrigerated coils that collect the water. The water is then collected in an attached container. Once it gets full of water, you need to empty the container.

Be sure to put the humidifier in the areas of your home with the most moisture, such as the basement or bathroom. You may also put one in the living room or bedroom to give you the best air to breathe while you’re relaxing at home or sleeping.

2. Shorter, cooler showers

Taking a shower can contribute to the humidity in your home. A long, hot shower will put moisture into the air of your bathroom and can affect other parts of your home as well. 

To reduce house humidity in summer,   try taking shorter showers at a slightly cooler temperature. You should also have the bathroom well ventilated to help remove the moisture from your home.

3. Get fresh air

In some situations, your home may be more humid than it is outside. If that’s the case, open the window and let the fresh air come in. Not only will it help with circulation, but the less humid air will help with the high levels of humidity inside.

4. Use fans

Turn on fans to help move the air around your home. If the air is humid, spreading it around will help spread it out. Plus, the fan will help relieve sweating from the humid air. This is also great for when you only need to monitor the air in a small area.

5. Get rid of the plants

Plants can help make your home look and smell more pleasant. However, they can also increase the amount of moisture in the air as well. When a plant breathes in carbon dioxide, it releases water. That’s why you need to keep watering it. While they may look nice, you might want to keep the plants outside if you have a problem with the humidity levels in your home.

6. Insulation

Particularly if you live in an area with a lot of humidity outside, you should insulate your home well to prevent exterior moisture from getting inside. Insulation keeps outside air from getting in, and inside air from getting out. Certain building materials have higher insulation properties than others. It’s also important to insulate around windows and doors, where air can easily get in.

7. Be careful when using the sink

After you wash the dishes or brush your teeth, you can usually find water left on the counter. To prevent high levels of humidity in your home during the summer, it’s important to wipe it up to prevent it from getting into the air. Additionally, be sure to hang any towels appropriately to prevent any mold from growing.

Bonus Tip: Average Summer Humidity Map in the USA

We live in a large country with a large variety of weather. Different parts of the country are simply more humid than others. If you don’t like high humidity, you should move to a place that’s naturally dry. According to this average summer humidity map that shows humidity percentages by state, the states with the lowest humidity in summer are Colorado, Arizona, Idaho, and New Mexico. These low-humidity states are generally found in the American Southwest. This area is generally desert and is very dry.

On the other hand, you should avoid states with particularly high humidity. Georgia, Louisiana, Mississippi, New Hampshire, and Maine are the states with the most humidity. Most humid states during the summer are located in the American Southeast and Northeast. These states are stationed by the ocean, contributing to the wetness in their air.

These numbers reflect morning humidity percentages between 4 a.m. to 6 a.m. when humidity is at its highest. As the day goes on, humidity levels drop. The states with the highest humidity in the morning continue to have the highest humidity in the afternoon.

Final Thoughts

High humidity is just the worst. When it finds its way into your home, you have to do something about it. If your home is humid, it can really affect your home and possibly your health. Luckily, there are plenty of small things you can do to help reduce the amount of water in the air and make yourself comfortable.
