You can use a humidifier to humidify a room with air conditioning at night, thereby adding more moisture to the room. And if you are on a budget, opting for certain indoor appliances can also help humidify the room for maximum comfort. These help elevate dryness and keep dry skin problems at bay.

5 Ways To Humidify an Air Conditioned Room at Night

Both excess humidity and excess dryness are uncomfortable. While one will make you sweat and attract insects, the other will make your skin itch and cause dry coughing. Fortunately, choosing a middle ground can keep both extremities at bay!

Humidifying the room is a great way to ensure that the cooling from the AC is comfortable for longer. According to experts, your room’s humidity levels should be around 35% to 65%.

Anything lower than these numbers and you will go through problems like:

  • Sinusitis
  • Dry mouth
  • Chapped lips
  • Sore throat
  • Respiratory issues

To combat the above conditions, we will look at practical ways to keep your room well-humidified at night while your AC is on! And they are:

1. Add Some Indoor Plants That Add Humidity

If you love having some greenery around you, then it’s time to add them to your interior decor. Plants significantly reduce dryness around them and add moisture to the atmosphere by releasing oxygen. The best part about indoor greenery is that the plants’ soils help retain excess water so they do not dry out. 

And since these plants are prone to absorbing excess moisture, they can dry out quickly if you are not careful. So constantly water them on time and keep them in a cluster to create a moisture bridge between them. Indoor plants help to spread out the moisture in your room, adding a more humid atmosphere that allows you to tackle excessive dryness from the AC at night. 

Now you must choose humidifying plants for this task. Fortunately, several indoor plants help to retain the perfect moisture content in your room. Here are a few popular ones that you can get for your home:

  • Spider lily
  • Boston fern
  • Gold pothos
  • Peace lily
  • Areca palm
  • Lady palm

2. Get Yourself a Room Humidifier

A humidifier can help combat the dryness that ACs bring to your room. They help add adequate moisture to the room so that your AC’s chilly breeze can balance out with the humidity. 

There are various types of home and room humidifiers available, such as:

  • Warm mist
  • Cool mist
  • Vaporizer
  • Evaporator
  • Ultrasonic

They are often pretty affordable, especially if you are on a budget. Many assume that a humidifier is a standalone appliance. However, if you want your room to feel comfortable at night, combining an AC with a humidifier can help keep the dryness at bay. Still, always opt for a humidifier that is compact to your room’s size. 

There are multiple benefits to getting a humidifier for your air conditioned room, such as:

Keeps Health Issues at Bay

A heated room is cozy and helps keep several ailments at bay. Sleeping in a chilled room will have you suffering from:

  • A bloody nose
  • Cracked skin on your lips
  • Allergic reactions
  • Headaches from sinuses
  • Irritated and itchy eyes

Thankfully, these are all solvable by adding proper moisture to your room’s airways. And a humidifier is a perfect solution to these issues. 

It Reduces Snoring Issues

Another significant upside to having a humidifier in your air conditioned room is that it minimizes snoring issues. If you have a snoring problem but need to sleep in a room with AC, a humidifier is a must. It helps spread humidity in the room, providing sufficient moisture to clear the respiratory pathways. 

Reduces Your Risk of Getting the Flu

A home humidifier will help to keep influenza and flu viruses at bay. This is due to the virus particles failing to survive in high-humidity atmospheres. When the humidity is low, it allows flu viruses to thrive, deteriorating your health conditions. Hence a humidifier is a great way to keep your health in check.

3. Adopt a Cute Fish for the Room

Adopting a pet is best if you like it and know how to take care of it. Hence, opt for this tip ONLY if you love fish pets. The aim is to make use of a fish tank in your room. These colorful underwater critters are adorable and will also ensure your room feels comfortable.

So how does a fish tank help in this scenario? For starters, a fish tank needs a lot of water to keep your fish alive. The tank’s open top helps the water to evaporate and spread consistent humidity in the room. 

Of course, keep in mind that adopting fish comes with various responsibilities. You need to change the water regularly to remove any foul odors. Not to forget, it is crucial to keep the tank clean so it does not get messy or dirty while in your room.

4. Air-Dry Your Damp Clothes and Towels

If you have many clothes and towels to dry up, try air-drying them instead of putting them in a dryer. Doing so will help your room absorb moisture particles from the damp garments and balance out the dry, chill air from the AC. 

Now you might wonder how to hang wet clothes in a room. All you need is a peg line and some clips. And if you have no hooks in the room, you can always go for a drying rack that you can install yourself. 

Stack your:

  • Wet clothes
  • Shower towels
  • Kitchen apron, etc.

Let the air inside the room dry them up. The moisture and water from these towels will evaporate and blend with the air, allowing the room to maintain humidity while your AC is on. 

One trick to incorporate here is to hang the heavier garments in the room. Moisture takes the most time to evaporate from heavier cloth items, which helps to humidify the room. So before you get to bed, hang your heavy clothes in your room instead of using the dryer. Doing so will ensure that you do not wake up with your mouth and skin feeling dry.

5. Let the Shower Heat Humidify Your Room

If your air conditioned bedroom has an attached bathroom, you are lucky. You can let steam from the hot water spread into the room after showering to balance the dry, chill air from the AC. The steam will circulate through your room, creating a warmth that can counter extreme dryness

To make this more effective, leave your bathroom door open. Of course, this is only possible if:

  • You have enough privacy
  • Your window panes hide the room perfectly

If this is so, try this method for the best humidity flow. After your shower, keep the bathroom door open and the shower curtains down. Letting the curtains wait awhile allows the clinging water droplets to evaporate slowly into your room! These damp shower curtains work wonders for moisture content in your room. 


All in all, there are several effective ways to maintain humidity in an air-conditioned room at night. Not only does it make the atmosphere cozier, but it also keeps multiple health issues emanating from dry cold air at bay.
