Reasons Behind A Dry Mouth And Throat

Many people have the habit of going to bed with a glass of water kept at their bedside table because they know they will wake up with a parched mouth in the middle of the night. Normally, our body is capable of going into sleep mode for 8 hours without needing water as our mouth generates enough saliva. So, what are the reasons behind a dry mouth and why do you need a humidifier.

If you are on certain diuretics or medications to treat conditions like edema, blood pressure, or heart failure then you will experience dryness in the mouth. Sleeping pills or anti-depressants may also cause dry mouth.

Certain medical conditions such as sicca syndrome, diabetes, Sjogren’s, and lupus may also be responsible for dry mouth. If you have been experiencing dry mouth lately, consider discussing with your doctor to find out any underlying disease.

Some people experience dry mouth simply because they breathe from their mouth instead of their nose. This is the primary reason why people snore. Other reasons could be breathing issues, nose structural problems, and so on.

Sometimes a sudden change in climate can also cause dry mouth and skin issues. For example, if you suddenly move to a desert area, your body system and skin are not attuned with extreme temperatures. This is where you would need the best humidifier for dry mouth to balance the indoor environment at home.

Disturbed breathing in sleep is often referred to as sleep apnea and the condition may be worsened if you sleep on your back or drink alcohol close to bedtime. Making changes in lifestyle and taking care of yourself can improve dry mouth problems. Read on to find some quick home remedies.

Remedies To Improve Dry Mouth

Whether you have just moved to a desert location, or you have an underlying disease or you are on medications that cause dry mouth, here are some remedies to get relief from the discomfort. Inculcating these remedies in your daily routine and lifestyle can bring about a positive difference.

Increase your water intake

Studies have shown that dehydration could be the reason for dry mouth. Hence, we recommend that you increase your water intake and sip water in regular intervals to keep yourself well hydrated.

Change your medications

If you are taking any of these medications (antihistamines, hormone medications, antihypertensives, and bronchodilators), talk to your doctor about it. However, never stop or switch medications without consulting with the doctor.

Changes in lifestyle

Small changes in your lifestyle can bring about a big difference and help you get rid of excessive dryness. So, make a conscious effort to get rid of the dehydrating habits such as limiting your alcohol use, avoiding caffeine, quitting or cutting down smoking, and reducing sugary intakes.

Chew sugarless gums/ Suck sugarless candies

You can get some short term relief from the dry mouth by chewing on sugarless gums or sucking on sugarless candies. Some gums or candies may contain ingredients like xylitol that aid in stimulating the production of saliva.

Try herbal remedies

There are certain types of herbs that stimulate your salivary glands to produce saliva and bring about some temporary relief. You can use these herbs in your food or as juices to encourage salivation. Examples of such herbs are ginger, aloe vera, sweet pepper, marshmallow root, nopal cactus, and so on.

Improve oral care

Sometimes bad oral hygiene could be the reason for dry mouth and you may improve this by choosing better oral care. We suggest improving your oral routine by flossing frequently, using alcohol-free mouthwash and fluoride toothpaste.

Using the best humidifier


Choose one of the humidifiers mentioned above to increase the humidity levels in your room to avoid waking up with a dry mouth. Consider your specific needs such as area coverage, water tank capacity, etc before selecting a product.

Try over-the-counter substitutes

For those with extreme dry mouth problems, consider using the over-the-counter substitutes from your local pharmacy to get some temporary relief. You may consult your doctor to suggest a suitable brand for you.

What type of vapor is safer – cool mist or hot mist?

If you are concerned about having boiling water in your room, you may switch to using cool mist which is much safer. However, the warm mist is a better option to prevent mold or mildew growth in the device.

Some people consider adding salt to the water tank to replicate the ocean-like mist. However, we discourage you from doing so as this can damage the metal components inside the humidifier. It can also clog the filter and impact the overall performance of the device.

Is there anything wrong with my device because I can’t see the mist?

Some models are designed to produce invisible mist, so if the water level is dropping and the device is taking air then it is producing mist. Please check with the user manual to find more details about the type of operation.

What size humidifier should I buy for my bedroom?

For an average bedroom, we suggest buying a device that is capable of covering an area of 700 to 800 square feet. Some models are powerful enough to increase the humidity level in the entire house and cover an area over 2000 square feet.
