It’s the middle of summer and the weather is hot and humid. You’re trying to get some relief by running a dehumidifier in your home, but are you really making things better? Could a dehumidifier actually be making you dehydrated? In this blog post, we’ll explore the dangers of using a dehumidifier and how it can lead to dehydration. Stay hydrated, everyone!

Dehumidifiers work by pulling moisture out of the air and into the unit. This process can help to improve indoor air quality and reduce mold growth. However, it also means that the air in your home is becoming drier. Dry air can lead to dehydration, which can cause a host of problems including dry skin, headaches, and fatigue.

If you’re using a dehumidifier, it’s important to make sure that you’re also staying hydrated yourself. Drink plenty of water and avoid caffeinated beverages which can further dehydrate you. You may also want to consider running a humidifier in addition to your dehumidifier to help add some moisture back into the air.

What is Dehydration?

Dehydration is when your body does not have enough water. You can become dehydrated from losing too much water, not drinking enough fluids, or both. Dehydration can be dangerous because it can lead to other health problems such as heat exhaustion and heatstroke.

When you are dehydrated, your body does not have enough water to function properly. Dehydration can cause your blood pressure to drop, your heart rate to increase, and your body temperature to rise. If you are dehydrated, you may also feel dizzy, lightheaded, or tired.

Dehydration is especially dangerous for young children and older adults because they are more likely to become dehydrated. Dehydration can also be dangerous for people who have certain medical conditions such as diabetes, heart disease, or kidney disease.

What Are The Symptoms of Dehydration?

Dehydration can cause a number of symptoms, including:

  • Feeling thirsty.
  • Having a dry or sticky mouth.
  • Urinating less than normal or having dark yellow urine.
  • Feeling tired, dizzy, or lightheaded.
  • Having dry skin.
  • Feeling irritable or cranky.

If you are experiencing any of these symptoms, it is important to seek medical attention immediately. Dehydration can be a serious condition, and it is important to get treatment as soon as possible.

If you think you may be dehydrated, there are a few things you can do at home to help yourself feel better. First, try to drink plenty of fluids. Water is always a good choice, but you can also try juices or sports drinks. It is important to avoid caffeinated beverages, as they can actually make dehydration worse.

If you are still feeling dehydrated, or if your symptoms are getting worse, it is important to seek medical attention right away. Dehydration can be a serious condition, and it is important to get treatment as soon as possible.

How Much Electricity Does a Dehumidifier Use Per Month?

This is a question that we get asked a lot, and it really depends on how often you use your dehumidifier. If you live in an area with high humidity, you may need to run your dehumidifier more often than someone who lives in a drier climate. On average,  a dehumidifier will use about 60-90 watts of electricity per hour. So, if you use your dehumidifier for 12 hours a day, it will cost you about $0.72-$0.81 per day to operate.

While the cost of running a dehumidifier may be relatively low, there is one potential downside to using one that you should be aware of – dehydration. Dehumidifiers work by pulling moisture out of the air, and if you use one in a small room, that moisture has to go somewhere.

Dehumidifier Humidity Setting In The Summer Is 50% RH Too Low?

The answer is no, 50% RH is not too low for a dehumidifier in the summer. In fact, it is the ideal setting for a dehumidifier. The reason for this is that the air conditioner will remove moisture from the air and lower the humidity to around 50% RH.

If the humidity was set any lower, the air conditioner would have to work harder to remove the moisture from the air. This would result in higher energy bills and possibly shorten the life of your air conditioner. So, if you want to save money and prolong the life of your air conditioner, set your dehumidifier to 50% RH in the summer.

Dehumidifier Humidity Setting In The Winter

During the winter, you should set your dehumidifier to a lower humidity level than during the summer. This is because the air is drier during the winter, so you don’t need to remove as much moisture from it. A good rule of thumb is to set your dehumidifier to the same setting as your thermostat. This way, you can maintain a comfortable indoor humidity level without overworking your dehumidifier.

Can a dehumidifier make it hard to breathe?

How Often to Use a Dehumidifier?

How often you should use a dehumidifier depends on the climate and weather conditions in your area. In general, you should use a dehumidifier when the humidity level in your home exceeds 50%.

Can a Dehumidifier Cause Sinus Problems?

There is no definitive answer to this question as everyone’s sinuses are different and react differently to various stimuli. However, it is possible that a dehumidifier could cause sinus problems in some people, especially if they have sensitive sinuses or are allergic to dust or mold spores. If you notice that your sinuses begin to act up after using a dehumidifier, try adjusting the settings or switching to a different model. If the problem persists, consult your doctor for advice.


A dehumidifier can dehydrate you if you are not careful. When using a dehumidifier, be sure to keep the unit away from your body and to drink plenty of fluids. If you experience any symptoms of dehydration, such as excessive thirst, dizziness, or lightheartedness, stop using the dehumidifier and seek medical attention.
