Have you ever wondered if a dehumidifier does more than just remove moisture from the air? If so, you’re in the right place. As an indoor air quality researcher with over a decade of experience, I’m here to tell you whether a dehumidifier can cool your room.
So, what exactly is a dehumidifier?
Think of it as the enemy of humidity. It’s a device that gets rid of that sticky, muggy feeling in the air by removing excess moisture. Dehumidifiers work by drawing air over a cooling coil, which condenses the water vapor in the air. The condensed water is then collected in a reservoir, which can be emptied manually or automatically.
But, here’s the question: can a dehumidifier also keep your room cool?
The short answer is yes, but not directly. Dehumidifiers don’t actually lower the temperature of the air, but they can make you feel cooler by removing moisture from the air. When the air is less humid, it can evaporate sweat more easily, which helps to cool you down.
In addition, dehumidifiers can help to cool your room by reducing the workload on your air conditioner. When the air is less humid, your air conditioner doesn’t have to work as hard to cool the air, which can save you money on your energy bills.
So, if you’re looking for a way to cool your room and improve your indoor air quality, a dehumidifier is a great option.
Does a dehumidifier cool a room?
How a humidifier can help you feel cooler, even if it doesn’t lower the temperature
Alright, now that we’ve scratched the surface on what a dehumidifier is, let’s dive into the nitty-gritty of how these nifty machines can help you stay chill, even if they aren’t dropping the mercury.
The role of sweat in cooling your body
Sweat, my friend, is your body’s built-in AC. When things heat up, your body starts pumping out sweat to cool you down. It’s like your personal cooling system.
How humidity affects sweat evaporation
But here’s the twist: humidity can be your sweat’s worst enemy. When the air is already loaded with moisture, your sweat struggles to evaporate. That’s when you feel all sticky and uncomfortable.
How Dehumidifiers Can Make You Feel Cooler by Removing Moisture from the Air
Now, this is where dehumidifiers swoop in as the unsung heroes. They pull that excess moisture from the air, allowing your sweat to do its job efficiently. Even though the thermostat reading doesn’t budge, you feel cooler and more comfortable.
Here’s a real life example for better understanding
Imagine you’re in a room with a temperature of 75 degrees Fahrenheit and a humidity level of 60%. You’re feeling a bit hot and sticky, so you start to sweat. However, the humidity in the air is making it difficult for your sweat to evaporate, so you’re not cooling down as quickly as you’d like.
Now imagine that you turn on a dehumidifier. The dehumidifier starts to remove moisture from the air, lowering the humidity level. As the humidity level drops, it becomes easier for your sweat to evaporate. You start to feel cooler, even though the temperature of the air hasn’t changed.
The science behind why dehumidifiers make rooms feel cooler
The physics of evaporation
First things first, it’s all about the physics of evaporation. Evaporation is the process by which a liquid (such as water) changes into a gas (such as water vapor). Evaporation requires energy, which is called the latent heat of vaporization. When you’re sweating it out, your body relies on sweat to evaporate and carry away excess heat, making you feel cooler. But there’s a catch.
The latent heat of vaporization
The latent heat of vaporization is the amount of energy required to evaporate one gram of a liquid at its boiling point. The latent heat of vaporization of water is 540 calories per gram. When humidity levels are high, it takes more energy to turn liquid sweat into vapor, leaving you feeling sticky and warm.
How dehumidifiers reduce the latent heat of vaporization in the air
This is where dehumidifiers come to the rescue. They strip away excess moisture from the air, reducing the amount of energy it takes to evaporate your sweat. Voilà! You feel cooler, and it’s not just a mirage.
Dehumidifiers remove moisture from the air by cooling it below its dew point. The dew point is the temperature at which water vapor in the air condenses into liquid water. When the air is cooled below its dew point, the excess water vapor condenses into liquid water, which is collected in the dehumidifier’s reservoir.
By removing water vapor from the air, dehumidifiers reduce the latent heat of vaporization in the air. This makes it easier for sweat to evaporate, which helps you to feel cooler.

Here’s a real life example, to make the science more digestible!
Imagine you’re in a room with a temperature of 75 degrees Fahrenheit and a humidity level of 60%. The latent heat of vaporization in the air is 540 calories per gram. This means that it takes 540 calories of energy to evaporate one gram of sweat from your skin.
Now imagine that you turn on a dehumidifier. The dehumidifier starts to remove moisture from the air, lowering the humidity level to 50%. The latent heat of vaporization in the air now drops to 500 calories per gram. This means that it now only takes 500 calories of energy to evaporate one gram of sweat from your skin.
As a result, you start to feel cooler, even though the temperature of the air hasn’t changed.
The benefits of using a dehumidifier to cool your room
So, you might be thinking, “What’s in it for me?” Well, using a dehumidifier isn’t just about getting rid of that sticky feeling. It comes with some fantastic perks.
- Improved air quality: Dehumidifiers can remove allergens, mold, and mildew from the air, which can improve your indoor air quality.
