In A Hurry?

If you require a humidifier and do not want to read the entire article, below are the recommended items from the article.  (Low, Medium and High Price)

Which Is the best Humidifier for Hot Weather

When dealing with Hot Weather, the best humidifier is the Keecoon 8L Diffusers for Essential Oils 2.11 Gal Ultrasonic Cool Mist Humidifier

However, this will depend on several things, like if you want it to do several tasks – like Dorm Room, or Cold and Flu symptoms.

There will also be costs for the humidifier - like Mist Type, Water Tank Capacity, Coverage Area and Noise Level. So as you can see, there is a lot in picking the right humidifier!

Are humidifiers used both in summer and winter?

You might be familiar with using a humidifier in winter when humidity levels drop because of central heating, but they are very useful all-year-round in dryer climates as well.

During hot summer months, the dry warm air can harm your skin and body, so using a cool mist humidifier while the air conditioner is on can protect you from nasal complications, itchy skin and eyes, throat infections and even seasonal allergies.

Do I need a humidifier during the summer?

The humidity levels drop significantly in warmer seasons, which comes with an increased risk of dehydration, skin allergy outbreaks, dry sinuses, sneezing and sniffling. You can benefit from the added moisture that a humidifier brings to get rid of respiratory symptoms and dry skin during hot summer days when dry air conditioning makes your life difficult.

What levels should a humidifier be set at in summer?

Monitor a humidity checker, known as a hygrometer, and set your humidifier accordingly. If you do not have a hygrometer, you could also use your smartphone, as there are apps that act like humidity checkers. Of course, if you buy a humidifier, most modern models have a built-in hygrometer, so you do not have to worry about purchasing another gadget for this alone.

Most specialists recommend a humidity between 30% and 50% in summer and spring, therefore set your humidifier to regulate the air moisture so that it falls somewhere above 30% and below 50% for a comfortable atmosphere.

Do Humidifiers Keep You Cool in Hot Weather?

It is a common mistake to confuse cool mist humidifiers with a gadget that makes the air in the room colder. That is what AC is for. Instead, the temperature in the room might seem even higher when using a humidifier, since high humidity levels encourage heat retention by preventing sweating. Some users may report that the cool mist can give the impression that the air is a little chiller, but it is debatable.

Which Humidifier Is Best for Summer: Cool Mist or Warm Mist Humidifiers?

You might notice that there are many types of humidifiers available on the market, with distinct features besides the basic function of adding moisture to the air, and consider comparing them before making a purchase.

There are steam vaporizers that use electricity to create steam. The steam is cooled down before being released. Then, there are ultrasonic humidifiers, that use vibrations instead of electricity, and evaporators, that blow air past evaporating water, to produce humidity.

If you are looking for a child-friendly humidifier, then you should opt for an impeller humidifier, since it uses rotating disks to vaporize water, as opposed to those that use heat. Last, but not least, you could purchase a central humidifier that can be connected to the central air conditioning in your home.

But what about which humidifier to use in winter and which one to use in the summer? You might wonder what humidifiers are best for hot weather, as opposed to those that bring the perfect levels of humidity in colder days. Deciding between a warm or cool mist humidifier can be tricky.

Warm mist humidifiers release steam by vaporizing water using heat. They have the benefit of more rapidly humidifying spaces, but they make a lot of noise too. Warm mist humidifiers are recommended if you want to use them with soothing medicinal vapours.

Cool mist humidifiers are safer since they do not use heat to vaporize the water. These models make less noise, they are safer to use in environments with children and pets, but they require more work in regular maintenance and thorough cleaning.

For cool mist humidifiers, you can choose from ultrasonic or evaporative models. Ultrasonic humidifiers use high-frequency vibrations to generate mist, and they are best with reduced noise levels. They must be thoroughly scrubbed every month to avoid health issues because of mould and bacteria build-up.

Evaporators are equipped with a filter and a fan which are used to distribute water vapour. If you are worried about mould, the latter is the best option, but you must keep in mind that it requires replacing the filter from time to time.

Best humidifiers for Summer and Hot Weather

People who use humidifiers all-year-round usually report that there are three types of humidifiers that work best in the summer. Evaporators, impeller humidifiers and ultrasonic humidifiers are the preferred options. The most mentioned model is the ultrasonic cool mist humidifier since it can relieve dry air conditions during summer, by making the air in the room more comfortable, which helps avoid allergy flareups, sinus congestion and dry skin problems.

By browsing through several user reviews on Amazon, you notice that there are a couple of humidifiers that stand out with benefits of using them during hot summer days. We compiled a list of highly reviewed humidifier models you should check out if you want to buy the best humidifier for your needs.

Things to help in Hot Weather

If you live in a humid climate (like Florida) then you'll need to know what type of humidifier is best for use when it's hot outside as they work a little differently than when they're used in less humid climates. A cool-mist humidifier is normally used during colder months because these models don't heat up and disperse warm air into your bedroom like a warm-mist model does.

1) Drink more fluids.

Drink lots of iced water with lemon as it helps with vitamin C absorption and reduces the likelihood of heat related illnesses, such as heat exhaustion or heat stroke.

2) Sweat it out.

Exercising in hot weather can help you cool down and avoid feeling sluggish or overheated. If you have access to the outdoors, consider exercising outside for its cooling benefits. Adding some light cardio exercises into your regular workout routine can keep your metabolism up, too by giving you a boost of energy to complete more intense exercises later on in the day without burning yourself out early on during a summer workout plan.

3) Take an ice bath.

Get as cold as you can by taking a nice, long bath in colder-than-normal water. The most effective method of cooling your body down is to get into a tub of ice water and stay there for at least 15 minutes. Just make sure that you don't fall asleep! This can lead to hypothermia - not the desired result here.

Try this the day after exercising so that you're not burning precious energy to cool off and allow yourself more time to recover before your next workout session.

4) Refresh with salads, veggies & fruit.

Salads and vegetables such as tomatoes are great sources of fiber which can help cool down your body temperature. Fruits like watermelon are delicious treats that will provide you with some quick-digesting carbohydrates to give you a boost of energy and hydration for rehydrating after a tough workout. Avoid greasy or heavy foods that will weigh you down.

5) Drink barley tea.

Barley tea is the perfect way to cool down on summer days when the mercury rises. It has a cooling effect on the body and helps prevent dehydration by promoting urination. It's a good idea to drink barley tea throughout the day as it can help you cool down with each sip.

6) Sleep.

Take a few hours break in the afternoon if you're working outdoors during the middle of the day, perhaps after lunch or right after dinner. As we know, sleeping is important and when it's hot and you're working outside in the heat, it's also important to keep yourself hydrated while sleeping so that you are able to get up in time for a cool shower and plenty of water to begin another productive day at work.

7) Humidify your bedroom.

Don't leave the AC unit running all summer long! Set the room up for a bit of a cool down. Keep the windows open and spray water mist all over. You'll not only cool down, but you'll also increase your humidity level which gives you a better sleep each night.

8) Protect yourself from UV rays.

Apply any sunscreen before going outdoors, especially during the warmest part of the day. This will help prevent sunburn and damage to your skin by preventing it from breaking down too quickly when exposed to the sun's harmful UV rays which can cause cancer and premature aging of skin cells when exposed to sunlight over time.

8) Humidify your house.

Do this by running a humidifier or a cool misting fan in your bedroom. This helps you stay hydrated while sleeping and will also help prevent dry skin and itchy eyes too. This is the perfect way to cool down on hot summer nights.

9) Drink natural, healthy fruit juice.

Avoid processed sugars such as high fructose corn syrup, which most juices are made of these days, and try fruit juice made from real, fresh vegetables and fruits instead. The best ones are organic. Try it for a refreshing drink any time of the day and you'll be amazed at how cooling it is!

10) Be in the shade.

Shady places in your yard during the hot summer months are always a good idea to escape the heat. Shade trees help you stay cool too by providing you with a place to sit under or even lie down in and enjoy some quiet time during the hot summer months.

11) Take a cold shower.

Take a nice, long, cold shower by setting the temperature on low or cool and spending at least 5 minutes in it. This will help cool your body down quickly so that you're ready to go back outside and exercise again after only a short rest period. Just make sure that you don't stay in there longer than 15 minutes!

12) Watch out for heat stroke or heat exhaustion.

Symptoms of heat stroke include confusion, unconsciousness, nausea and extreme fatigue. Although this does not usually happen to people working outside during hot weather, it can be dangerous to your health and can even kill you if you don't treat at soon as possible.

Symptoms of heat exhaustion are similar and include heavy sweating, fatigue, weakness and dizziness.

If you find yourself feeling these symptoms or notice someone who is having a medical emergency due to high temperature levels or overexertion in the summer time heat contact 911 immediately for help in cooling them down with cool water or ice packs until professional help arrives.

13) Be mindful of your walking.

Make sure you walk in the shade as much as possible. Walking in the sun with no sunscreen can cause severe damage to your skin, so avoid this at all costs. Your skin is your largest organ and it's important to protect it from the sun. You may also want to consider wearing a hat and sunglasses when outside for extended periods of time on hot days.

14) Stay cool.

The best way to beat the summer heat is to stay out of the sun or at least stay in shaded areas as much as you can throughout the summer months, especially during the hottest part of day, typically from noon-3pm during summer months on most days.

Please Note: Just because a humidifier is marked, for example “Baby Room”, it will still work for other things, for example “Living Room” or “Plant Humidifier”

Other Questions

What type of humidifier is best for dry heat?

A humidifier that is built to release cool mist is best for dry hot air. Dry air causes dehydration, which can lead to sore throats, nosebleeds and other problems. Cool mist humidifiers add moisture back into the air while providing a cool feeling.

In dry heat the air contains less moisture than normal because the warmer air can’t hold as much water vapor. The water vapor is instead transformed into clouds, fog, or dew at the higher temperature. When dry heat increases the evaporation of liquids and contaminants occurs at a faster rate than normal.

Can I use tap water in humidifier?

It’s generally safe to use tap water in a humidifier if the filter is changed regularly. If you are concerned about the quality of your tap water, or if you have had skin irritation, asthma attacks or other problems associated with humidifier use, use distilled water instead.

Distilled water has had most of its contaminants boiled out of it and is usually available in supermarkets and grocery stores. It is also inexpensive, costing only a couple of cents per gallon compared to $1 or more for filtered tap water. Distilled water must be boiled before it can be used in a humidifier and cannot be used as drinking water.

Can you over humidify a room?

Yes, if you have a whole house humidifier it is possible to over humidify the air. A whole house humidifier helps distribute moisture evenly throughout the home and in some cases will over supply moisture for one room or area. The air may feel stuffy and moist in that area while other parts of the house may not be as humid.

Another problem with a whole house humidifier is that it doesn’t let you control how much moisture is in each room. This can present problems when it comes to furniture or floors made of wood or other materials that are prone to damage from excess moisture.
