Why am I particularly thirsty after waking up

Under normal circumstances, when you wake up from a sleep, you should feel energetic and comfortable. However, many people have an additional reaction, which is thirst. And they are particularly thirsty. This is not just one or two days. This thirsty feeling occurs repeatedly over a period of time. In fact, most of the reasons are caused by mouth breathing while sleeping. After falling asleep, you breathe through your mouth and nose together. After a few hours, it would be strange if you are not thirsty. Let's talk about the reasons for this situation.

The phenomenon of mouth breathing during sleep generally occurs in three types of people:

1. If you have the habit of snoring during sleep, you must open your mouth and nose and breathe at the same time;

2. Chronic lung disease: emphysema, chronic bronchitis, etc., especially some elderly people, whose lung function is generally poor and the body is severely hypoxic, so they often perform compensatory breathing with their mouths open. Once the lung function improves, the symptoms of dry mouth will be relieved. 

3. People who are overly tired during the day or seriously ill elderly people have weak constitutions and tend to sleep deeply and soundly. They are often hypoxic and therefore breathe through their mouths to get enough oxygen. However, the symptoms of this type of elderly people will be alleviated after their fatigue is eliminated, their illness becomes milder or they recover.

4. Vitamin B2 deficiency: When the body lacks vitamin B2, it will also cause dry mouth, as well as ulcers at the corners of the mouth, dry throat, and tongue ulcers.

When you sleep on your back and breathe with your mouth open, or breathe through your nose and mouth at the same time, your body fluids can easily evaporate. It is recommended that the elderly with this condition should change their sleeping position and avoid lying on their backs. They should adopt the "bow-like" position and it is best to lie on the right side. Try not to breathe with your mouth open and raise the pillow appropriately. Another advantage of sleeping on the right side is that the stomach outlet is at the bottom, which helps the stomach contents to be discharged and avoids compressing the heart.

It should be noted that certain diseases can also cause the elderly to breathe through their mouths. For example, elderly people with severe snoring must breathe through their mouths and noses at the same time. Patients with chronic bronchitis, heart disease, etc. often feel a lack of oxygen when they are ill, and this feeling is more obvious after falling asleep. Therefore, people breathe through their mouths to get more oxygen intake. People who are overly tired or weak during the day often suffer from hypoxia during sleep, so they are also prone to breathe through their mouths to get enough oxygen intake.
