Why Are My Lips Bigger In The Morning

There are numerous reasons for your lips to be swollen in the morning, ranging from common ones to potentially harmful ones.

Though the vast majority would be happy to have swollen and fuller lips, it is best to know the cause.

Visual Distortion

Why do my lips look bigger in the morning? Have you considered visual distortion?

This is the first thing to consider when your lips look bigger after waking up. Sometimes, things seem different when we are tired. 

In that same regard, the lips can sometimes seem bigger if observed by a pair of exhausted eyes.

The information sent to our brain might not be processed well if we are extremely tired.

Gravitational Pull

When sleeping, the body is horizontal, which causes fluid to move to the head and build in your face and brain.

This explains why people frequently wake up with not only swollen lips but puffy faces as well. 


If you expose yourself to the sun for too long, you can get sunburned.

The thing about being sunburned is that most of the symptoms don’t show until after some time.

So your swollen lips could be a result of overexposure to sunlight.

taking blood pressure

Blood Pressure 

The average human blood pressure increases while they are asleep, which means that we produce more blood at night. 

Due to the increase in blood pressure, some parts of the body swell, and the lips just happen to be one of them.

Note: Sometimes, it's not just swollen lips, you can sometimes wake up to puffy eyes and a bloated face.


As we all know, heat causes expansion. Under high temperatures, the fatty tissues in the body expand.

This could be a possible reason why your lips are swollen in the morning.

table salt

Salt Accumulation

Another reason for a swollen lip when you wake up could be because of your salt consumption.

As we all know, too much salt causes swelling in some parts of the body, like our feet for example. 

If you consumed a meal that had a very high concentration of salt before you slept, it is likely for your body to retain fluids.

This, in turn, is what causes not just your swollen lips but swollen eyelids when you wake up.


A lot of people have the typical nighttime fluid retention that causes swollen lips and puffy faces.

If someone sleeps too little or too much, the fluid retention will cause swelling.

sleeping position

Not only that, your sleeping position can make fluid gather on your face, so even if you get a good night’s rest, your lips and face will be swollen. 

Even with all that has been said, we are still yet to answer the question, “why are my lips so big in the morning?” fully.

Sometimes, it doesn’t even have to be in the morning.

Over time, it has been discovered that no matter the time of day, the symptoms are persistent in those who just woke up. 

So it could be an afternoon nap and you would still get swollen lips after awakening.

In some cases, the reasons are harmless, and swelling will go down after some hours. But sometimes, the cause of the swelling could be something serious.

Here are the other causes of swelling lips people rarely consider:

Allergic Reaction

Swollen lips could be a result of an allergic reaction to particular foods or a reaction to a certain medicine.

It could also be associated with insect bites. As we all know, we are exposed to insect bites when we are unconscious. 


I woke up with swollen lips one time and I thought it was harmless and would go away after some time.

Then when it didn’t go I applied ice and it only got worse.

I later found out when I went to my doctor that I had a cold sore and that my tampering was what made it worse. 

lip wounds

Sometimes, your lips can be swollen as a result of an infection or, in my case, a virus. It could also be a pimple close to the lips. 

Tip: Whatever it could be, it is best to consult a doctor.


An injury to the lip could result in swelling, which develops gradually over time.

You can also injure yourself when biting your lips without knowing. 

Sometimes, sleeping on a hard surface or in an awkward position can cause minor and sometimes major injuries to some parts of the body.

This could also cause inflammation.
