 Why Do My Lips Look Bigger In The Morning

If you ask most people, they will tell you they are not ‘morning people,’ which is to imply they are never in a good mood when they wake up. Like you don’t feel good when waking up, most people don’t look good in the morning.

One of the most common parts of this is your lips looking bigger when you wake up. Today we will take a closer look at why this happens, along with more details in sleep and how it affects your body. Let’s get into the details;

Why Do My Lips Look Bigger In The Morning?

The body needs more blood supply to any organs when it is cold. When you sleep, the lips are usually cold at night, and they lose heat quickly as they are exposed. 

This means that the body will pass more blood to them, and they will expand with the blood supply, and it takes some time to return to the expected size; hence your lips are fuller.

Why Is My Lip Swollen When I Wake Up?

Waking up with a swollen lip can be shocking, especially if you didn’t go to bed with an injury the night before. 

The most common reason for lips to swell is trauma to the mouth, but other reasons can cause it; some are not very obvious.

The first thing you need to think about is allergies. Some allergic reactions to certain foods in your home or bed could cause your lips to swell overnight. 

If the problem came up after you got something new or changed your lifestyle, there is a problem with the new plan.

Foods like fish, nuts, milk, and eggs commonly cause swollen lips. You can also have allergic reactions to certain medications like penicillin or another antibiotic. You may also experience other reactions like wheezing, itching, and angioedema.

Some skin infections and conditions can cause swollen lips, such as pimples on or near the lip. Cystic acne can cause severe swelling on the lips, and it can also lead to large boils anywhere on the body, including the lip.

Cold sores and herpes infections can also cause lips to swell, appearing overnight. If you spend time in the hot sun without protection, you could get sunburnt. Sunburnt lips will often swell and crack, but the effects will subside within a few days. 

Cellulitis is a common bacterial skin infection that can cause swelling of the lip or other body parts. 

Some conditions affect the muscles and nerves in your face, which can cause you to wake up with a swollen lip or similar symptoms.  


Many factors can lead to swollen lips in the morning, and if you can pinpoint the reason behind your issue, it is best to see a specialist. It can be an allergic reaction to food, especially animal proteins, or indicate something more serious.
