It is best to find out the cause and treat it symptomatically.

What causes dry lips when waking up from sleep?

Air Drying

In some places, the air is drier at night, such as the northwest. If you don't drink enough water before going to bed, you may experience dry mouth due to the dry air when you sleep at night. According to scientific calculations, adults need to maintain a balance between the amount of water they replenish and the amount their body consumes every day, which means that everyone should drink at least 1,500 ml of water a day. If you drink too little, you will easily get dry mouth.

Sleeping posture problems

Some people prefer to sleep on their stomachs or sides. What will happen if this happens? That is drooling. So why do people drool while sleeping? One of the reasons is sleeping posture. When saliva keeps flowing out and recycling, your mouth will continue to secrete saliva without the control of your brain, and the water in your body will be consumed too quickly. This is one reason why you have a dry mouth when you wake up from sleep.

Body heat

If your body is getting inflamed, your mouth may be very dry when you wake up from sleep. For example, if you eat a lot of foods that are easy to cause inflammation during the day, your mouth may be dry at night. If it is not a special case, you can drink some herbal tea to reduce the heat. If this happens often, you should get checked. Under normal circumstances, the human body will not have a dry mouth after waking up from sleep.

Indoor humidity is too low

When we sleep in a relatively closed environment, if the air circulation is poor, we are prone to dry mouth and tongue. The most typical example is staying in an air-conditioned room for a long time in the summer. You will feel dry mouth even if you are not sleeping. In winter, people prefer to sleep with doors and windows closed. The air circulation is poor and the humidity is low, so dry mouth is very normal.

Liver and kidney yin deficiency

In traditional Chinese medicine, dry mouth is often caused by liver and kidney yin deficiency. Medically, dry mouth is also known as Sjögren's syndrome. Another common point is that many people who like to sleep with their mouths open are more likely to have a bad taste in their mouth, because this will cause the lingua franca at the top of the mouth to hang down, thereby blocking the respiratory tract and causing insufficient oxygen intake. This situation can be improved by adjusting the height of the pillow or lowering the head.
