Best Humidifier For Colds And Flu

Difference Between Cold, Flu, and Allergy

Cold, flu, and allergy affect your upper respiratory system. They all make you feel lousy and uncomfortable. Moreover, no known medication can treat any of these conditions. However, there are apparent differences in the symptoms of these three conditions.

If you understand the differences in their symptoms, you will manage them more effectively than when you do not know the differences. Here are key things that differentiate colds, allergies, and flu.


The sudden rise in body temperature is not common in all three conditions. A person who has flu will immediately experience a sudden and abnormal rise in their body temperature. The temperature may rise even to about 104 degrees Fahrenheit and remain at that level for four days.

If you have an allergic reaction, your body temperature will not rise at all. If you have a cold, you may either experience a fever or not. Thus, an allergic reaction does not lead to a fever.

Chest Discomfort and Coughing

Chest discomfort and coughing are common symptoms of cold and flu. If you have a cold, you are likely to experience mild to moderate levels of chest pain. You are also expected to experience a hacking cough.

Similarly, it is common for anyone who has flu to experience chest pain and coughing. However, this symptom is not common in allergic reactions.

Sneezing and Stuffy Nose

A lot of sneezing invariably accompanies colds. You will also experience stuffy noise when you have a cold. It is also common for anyone experiencing an allergic reaction to experiencing a stuffy nose and sneezing. However, these symptoms are hardly seen in someone who has the flu.

Prevalence, Prevention, and Treatment

A virus causes flu and colds. It is complicated to get effective treatment for conditions that are caused by viruses. Usually, you can only take medication to relieve the symptoms but not treat the underlying condition.

For allergies, you can get an allergy injection and control the environment to stop your body’s allergic reaction.

Colds occur as frequently as three to four times a year. Flu is less common; they occur only once a year. However, allergic reactions can occur as often as the conditions that cause them are present.

You can prevent the occurrence of flu by taking antiviral drugs or getting an annual vaccination. You can also prevent the occurrence of allergic reactions by controlling the environment. Sadly, there is nothing that you can do to prevent the occurrence of colds.

Reasons a Humidifier Can Help You Fight Cold and Flu

Using a humidifier in the house can help effectively fight colds and flu. Here are a few ways in which a humidifier can help you fight and keep off these two conditions.

A humidifier helps the breathing process.

When you have a cold or the flu, you will experience common symptoms such as nasal congestion, sneezing, and nasal congestion.

Although not all these symptoms are common in both colds and flu, they interfere with your breathing if they occur. You will find it difficult to breathe and stay comfortable if you have either a cold or the flu.

Using a humidifier helps the breathing process because the device dissipates moisture into the air. The mist that the humidifier dissipates finds its way into your nasal passages and makes the air passage process easy. Because of this process, you should use a humidifier that releases warm moisture if you have a cold or flu.

Limit the Spread of Germs

Viruses thrive in dry air conditions. However, these germs, which cause colds and flu, struggle to survive in humid weather. Using a humidifier directly increases the amount of humidity in the air in your home.

Therefore, when you have an excellent humidifier operating in your home, you make it very difficult for viruses and other germs to survive and spread around.

Help you Rest more and Feel Better

There is no known effective treatment for colds and flu. All the medications that you use help to relieve the symptoms. Your body is supposed to fight off the infection after some time.

Having enough rest and dealing with the symptoms is one of the most effective ways of helping the body fight off flu and cold viruses.

A humidifier can help you rest properly at night and during the day because it makes the air comfortable to breathe. Thus, if you have a cold and get your humidifier running, your body will be at ease to fight off the infection because you will rest well.

Prevents Infections

There are very tiny hairs on the inside of your nose. The cilia, as they are called, play a very critical role in keeping your healthy. As you breathe, the hairs move back and forth to trap viruses and other germs. For the cilia to function correctly, they need to be moist always.

Dry and wintery air interferes with the way the cilia function. Having a humidifier in the house makes the air moist and comfortable for the cilia. As a result, your cilia function properly in warding off possible infections in the future.

Warm Mist VS Cool Mist Humidifier: Which is Better for a Cold

It is difficult to tell what between cool-mist and warm-mist humidifiers is the best for a cold. It would help if you remembered that the air that reaches your lower respiratory system is at the same temperature. Your system automatically warms the air to make it easy for your lungs and other related body parts to function correctly.

However, when you have a cold, you will experience a stuffy nose and other similar symptoms. The symptoms make it very difficult for one to breathe correctly.

Although both cool-mist and warm-mist humidifiers can be set to maintain the air’s humidity level in the home or room within the required range, there are fundamental differences in the way they function.

Cool-mist humidifiers make the air feel slightly chilly because they do not heat the water before moisturizing it. Your cold symptoms will feel worse if you are in a room where the is somewhat chilly.

Warm-mist humidifiers heat the water before vaporizing and dissipating it. If you sit in a room where a warm-mist humidifier is, you will feel the ambient temperature rise slightly.

Such conditions can help you cope with the symptoms of a cold better than when you are in a cold room. Therefore, a warm-mist humidifier is better for a cold than a cool-mist one.

Factors to Consider when Choosing the Best Humidifier for Colds and Flu

Having the right humidifier in your house if you have a cold or the flu can determine how fast you overcome the condition. Here are some of the most important factors to consider when choosing a humidifier for colds and flu.

Cool Mist Versus Warm Mist Humidifier

You must decide whether you need a cool-mist or warm-mist humidifier if you have a cold.

Using a cool-mist humidifier in the house will make the weather feel chillier than when you have a warm-mist one. A warm-mist humidifier will make you feel better and more comfortable if you have a cold than a cool-mist humidifier.

Humidifier Capacity

There is no relationship between the humidification capacity of a humidifier and the capacity of the water tank.

The humidification capacity refers to the amount of moisture that the humidifier can dissipate within 24 hours. The humidification capacity of a humidifier is also related to the area that the device can serve effectively.

It would help if you got a humidifier that can dissipate its moisture adequately across the entire space of your room or house. Your decision depends on whether you choose to use a portable humidifier or a whole-house humidifier.

Other Ways to Deal with Colds and Flu

There are many other alternative ways of dealing with colds and flu apart from staying in a house with a humidifier.

Here are some different ways that you can use to ease the pain of the symptoms of flu and colds and get well fast.

  • Blow your nose. Colds cause the nasal cavity to produce a lot of mucus. It would be best if you cleared the mucus from your nasal cavity so that you can heal fast. Ensure that you blow your nose as often as there is a need to do so. Ensure that you do not apply excessive pressure when blowing your nose to protect your nasal cavity from damage.
  • Take a rest. Taking a rest in a warm and comfortable environment helps to fight colds and flu. When your body is relaxed and gets enough rest, it can fight off the viruses that cause colds and flu successfully. Thus, if you have a cold, please take some time to rest in a warm and comfortable environment.
  • Use warm and salty water to relieve the symptoms. Gaggling warm and salted water helps to reduce the symptoms of colds and flu. The warm and salty water effectively kills off bacteria and other germs in your upper respiratory system. If you gaggle and warm and salty water when you have a cold, you will feel better. Moreover, by killing off bacteria and other germs, warm and salty water helps you feel better quickly.
