There’s nothing worse than having a persistent cough that just won’t go away. It can interrupt and impact the quality of your sleep, making you feel exhausted the next day. You might also experience headaches and dizziness. 

Unfortunately, it can be a never-ending cycle as the more you cough, the more uncomfortable your throat feels. A dry atmosphere in your home is more likely to aggravate your cough, which is why increased moisture can make a big difference.

Higher humidity can not only ease your coughing but will also help relieve cold symptoms and sinus congestion. Using a humidifier is a great way to raise moisture levels in your home. Luckily, we’re here to help you find the right one to ease your coughing and help you get a more restful night’s sleep.

When picking out our top choices we looked at weight and tank size, as well as special features like:

  • Auto shut off
  • Night light
  • Break-resistant water tank
  • Aromatherapy tray for essential oils

It’s important to consider the size of your room together with your budget before purchasing a humidifier. The Honeywell Cool Moisture Humidifier is less than $40 and covers 150 square feet. However, the Hupro Premium Humidifier might be more suitable if you have a larger room as it covers 500 square feet.

To ensure we found the best humidifiers for coughs, we used consumer reports analysis to eliminate any false and unhelpful reviews. All our recommendations came from genuine people like you who have previously used these models.

Frequently Asked Questions

How does a humidifier help with coughs?

When you have a cough, it can dry out your throat and nasal passageways. This is particularly likely to occur when the air in your house has low humidity. A humidifier can correct this problem by raising the humidity. When the humidity is higher, the symptoms of coughs, colds, sinus congestion, and sore throats are significantly reduced. Most people with these conditions find that having a humidifier results in a more restful night of sleep. 

What are the benefits of a humidifier during flu season?

Dry air can be a problem during flu season because flu germs and other viruses spread and survive better in dry air. Increasing indoor humidity levels makes it less likely that these germs will survive and be transmitted to people. It is a good idea to keep the humidity in your home between forty-five percent and fifty percent relative humidity to keep germs from spreading.

Because flu and virus symptoms are typically things like a runny nose, sinus congestion, coughing, and a sore throat a humidifier can help reduce the symptoms. So even if you do get sick with the flu or a virus, you will not feel as bad, helping you to get over it quicker.

What humidifiers are better for coughs, cool or warm-mist?

For use around children who have a cough, it is generally safer to use cool-mist humidifiers. This is because if a child gets too close to the steam or hot water from a warm-mist humidifier or steam vaporizer, they could get burned. However, if the humidifier is intended for adult-only use, then both cool or warm mist humidifiers do an equally excellent job at helping those who suffer from coughing. Which you choose rests entirely on personal preference.

A cool-mist humidifier may be more relaxing for some, while the warmer air produced by a warm-mist humidifier may be more preferable for others. Consider which of the two you would prefer when looking at which humidifier to purchase.

Which Humidifier is best for you?

Humidifiers are an excellent way to increase the humidity of dry air in your home. In doing so they can help several health problems that are directly connected to dry air. They can also help relieve the same symptoms when caused by a cold. The moisture levels produced by humidifiers can also hinder the spread of the viruses that cause colds. As a result, there are several ways that humidifiers can help improve health problems. 

They are of course by no means a cure-all, but they can help with the symptoms of coughs and colds and prevent their spread as well. So, while a humidifier does not cure any disease, it can help relieve the symptoms of colds and dry air-related problems.

If you get a humidifier for your home, you need to find one that will fit your needs. Do you value portability over a unit that has filters, or vice versa? All of the units mentioned above offer something unique that will likely stand out to you if you consider your needs.
