Can a Dehumidifier Dehydrate You?

Here's a trivia question that my friend asked me the other day. Could someone dehydrate to death if they fell into a deep sleep while a dehumidifier is running? While we all have a good chuckle, surprisingly there are many who think that a dehumidifier may actually over-dehydrate them. In this post, we are going to debunk all your concerns and prove once and for all, a dehumidifier will not make you dehydrated.

What Are The Symptoms of Dehydration?

  • Very thirsty
  • Dry mouth
  • Dry eyes with no tears
  • Fatigued/ sleepy
  • Decreased in urine frequency
  • Dark, yellowish urine compared to normal output
  • Headache
  • Dry skin
  • Dizziness
  • Low blood pressure
  • Rapid heart pumping

Can a Dehumidifier Make You Dehydrated?

You can never get dehydrated with a dehumidifier even if you run it throughout the night. Dehumidifier is a simple appliance designed to absorb moisture from the air. You can set the ideal humidity level between 30-50 percent and the dehumidifier will not go below that point. Even if you ignore the setting, turn it on at turbo speed, and run for consecutive hours, your body fluid will still retain at a good rate. Most people will feel dehydrated after waking up from a long nap is likely due to lack of water, dry air, climate, food allergies, or illnesses.

To give you a better perspective, people in Arizona or Nevada experience a very low relative humidity level below 20%. Even then, no one suffers from dehydration to death during their sleep. While extremely low humidity can cause dehydration, a dehumidifier simply does not have the capacity to do so.

What is Dehydration?

Dehydration is a condition where your body fluid does not have sufficient water or fluid to function normally. In other words, water intake is less than water outtake. This happens when you are losing water through sweat from the heat, physical activity, diet, and medication. A sickness that leads to fever, vomiting, diarrhea also accounts for the huge water loss. With the rise in blood sodium level and deficiency of electrolytes plus carbohydrates, if you don't replace the lost fluids, you will suffer from severe dehydration. A clear sign if one is experiencing weaknesses both physically and mentally.

There are lots of reasons why a person would consider getting a dehumidifier. For one, it is to help manage their home humidity level and protect personal belongings from rust, rot, decay. Excessive moisture in the air can lead to crack tiles, wallpaper peeling, and water stains. It will aggravate allergies as the home is infested with mold and mildew spots. The stench of the stagnant water and mustiness smell can also be unbearable to live with.

How Much Electricity Does a Dehumidifier Use?

Dehumidifiers are NOT expensive to run. On average, a 70-pint dehumidifier running more than 8 hours per day will cost you $10 a month. If you are planning to run a dehumidifier on a daily basis, make sure to choose the right dehumidification capacity that can cover the entire room. If you pick a less capable unit i.e. 30-pints, it will take a longer time to dehumidify a larger room and can significantly drive up electricity costs. Also, do consider the many Energy Star Rated models in the market that are more energy-efficient. You can learn more about dehumidifier power consumption ratings here.

Dehumidifier Humidity Setting In The Summer And Winter

The ideal relative humidity range would be between 30 to 50 percent where it is comfortable to breathe and can prevent mold growth. As summer weather is hot and humid, setting the humidity level too low forces the dehumidifier to run constantly resulting in a longer run time and a higher electricity bill. On the other hand, it is not necessary to run a dehumidifier during the winter as the air is already dry from the heating system.
