Reasons Why Your Room Could Be So Damp And Moist

Reasons Why Your Room Could Be So Damp And Moist

Most of us look forwards to getting a decent night’s sleep after a demanding day at work. However, the moisture and humidity in your room may cause you to wake up in the middle of the night intensely perspiring. Don’t worry if you’re wondering what makes your room look that way.

HVAC experts say there are a number of causes for the moist, humid feeling in your room. The outside weather is, nevertheless, the main offender. The other causes include high use of water-using appliances, an air conditioner that is too large, and water pouring into your home.

In this post, we’ll go into greater detail regarding the factors that contribute to excess humidity and wetness throughout the house, not just in your room. We’ll also talk about how to avoid these two things from happening and what harm they can do to your home.

What Brings About Dampness And High Humidity?

Reasons Why Your Room Could Be So Damp And Moist

A number of things can cause dampness and excessive humidity. Please note that these are only a few of the contributing elements. Each one will be covered below.

External Climate

The humidity levels in your home depend on the weather outside. This important issue impacts the entire house, not just your room. It’s crucial to weatherproof your property as much as you can because of this.

If you reside in a subtropical environment, this is an illustration of how the weather outside impacts the humidity levels inside your home. The humidity would be higher than usual, creating the ideal environment for mites and other pests to proliferate as well as favoring the development of mold and mildew.

There may be moist places in your home if you live in a location where the weather is consistently cold. This contributes to damp stains on the walls and wooden surfaces as well as the growth of mold and mildew.

Water Seeping Internally

There are a number of ways that water can enter your home and generate an excessive amount of moisture. One method involves external pressures. Examples of this include snowmelt, floods, and rain.

Condensation and one of the pipes bursting can also let water leak, both of which can result in flooding. A buildup of water on surfaces between walls and ceilings can result in property damage.

Extra-Large Air Conditioner

You may believe that an air conditioner aids in controlling the humidity levels in your room. Even though that is the case, using a larger unit does not necessarily translate into higher humidity levels.

Contrarily, the opposite occurs. A larger, more potent air conditioner will quickly cool a smaller space. A standard air conditioner has the ability to turn itself off when the temperature is just right.

The machine would shut down earlier than usual as a result of this. The unit will then come back on when the temperature starts to rise again.

The evaporator coil of the air conditioner is unable to function properly because of this cycle. This element’s function is to get rid of extra moisture in the air. Before it could do that, the temperature in the room would have been just right.

The result is that the space is chilly, but the air is quite moist. A wet environment with high humidity is produced as a result. Because of this, it’s crucial to speak with an HVAC professional about the size of the air conditioning unit you want to install.

Frequently Used Appliances And Showers

While taking a warm shower is excellent, especially on a cold day, doing so can increase the humidity in your house. Simple tasks like putting water on to boil or making broth in the stovetop also raise the humidity level. Washing machines, dishwashers, and other water-using equipment are also significant contributors.

Although it may seem ludicrous to you, it’s crucial to be mindful when using these appliances since the moisture they produce lingers in the air for a lot longer than you might imagine.

How To Recognize Damp And High Humidity

There are many ways to determine whether your room, and to some extent, your entire home, is experiencing dampness and excessive humidity. So, keep a close eye out for these indications.

The first sign is when you smell something musty in the air. This suggests that there is dampness in a particular area of your room. If you don’t fix this, mold and mildew can start to grow.

Another is excessive humidity and dampness-related wall discoloration. Water stains on the walls and wallpaper flaking could also arise from this. Another sign is having cold walls.

How To Avoid Dampness And High Humidity

Next, we’ll talk about various approaches of dealing with excessive moisture and humidity. Remember that there are many other options available; these are but a few examples.

Air Conditioner

As long as the air conditioner is the proper size for your house, it will do its job of lowering the air’s humidity. Because warm air holds moisture well, less would be produced with sufficient cooling provided by your air conditioner.

Exhaust Fans

We already discussed how showers and other water-using devices significantly increase indoor humidity levels. Installing exhaust fans is one approach to combat this.

A point of relief would be the use of exhaust fans, which would draw in the moisture in the air. At all times when you’re cooking or taking a warm shower, make sure to turn these on.

Circulation Of Air

By opening the doors and windows, proper air circulation can be introduced. You’re allowing the extra moisture in the air to escape outdoors by doing this.

Ensure that the air vents are open as well. If not, the extra moisture won’t be able to adequately vent outside the house.

Buy a dehumidifier if you want to successfully control the humidity levels. Dehumidifier purchases by homeowners have increased over time.

Dehumidifiers are reasonably priced, tiny, and portable. One approach in avoiding interior damage is to have one in your attic or basement.

How To Recognize Too Much Humidity

The simplest method is to use a hygrometer. The majority of meteorologists use this instrument to gauge the air’s humidity level. You can use a meteorologist in the comfort of your own home even if you’re not one.

Since you’re attempting to measure the average humidity level in your home, you should put the hygrometer in the central room. Due to the excessive humidity they produce, open windows, kitchens, and bathrooms must be kept far from it. Additionally, keep it away from places with poor airflow like corners because doing so would result in erroneous readings.

According to research, the optimal humidity range is between 30% and 50%. That level of humidity would produce a comfortable environment within your home and stop the formation of mold and mildew.


The weather outdoors is primarily to blame for the moisture and excessive humidity you’re experiencing inside your room, but there are other factors that could be at play that you should be aware of. To solve the problem, it’s crucial to identify the symptoms as soon as feasible.
