As the saying goes, "Taking a good nap is like picking up a treasure.".
Modern medicine has found that taking a nap during the afternoon can not only relieve fatigue, restore energy and physical strength, but also help protect the brain and reduce the risk of cardiovascular and cerebrovascular diseases.
Traditional Chinese medicine also advocates sleeping at noon, believing that it can relieve fatigue, avoid heat, and nourish the heart. The noon time refers to 11pm to 1pm.
In fact, in addition to the above benefits, some abnormal manifestations of the body during a nap are like a barometer of health.
For example, the following two common symptoms during a nap may be signals of illness or even cancer. Don't ignore them as trivial matters~
1、 Open your mouth and breathe while sleeping
For a long time, many people have regarded "sleeping soundly with their mouths open" as a sign of sleeping soundly and soundly.
Little did they know that breathing while sleeping with your mouth open is mostly caused by pathological factors, apart from improper sleeping posture.
For example, when adults suffer from diseases such as rhinitis, sinusitis, maxillary sinusitis, maxillary sinus cancer, pharyngitis, etc., it can lead to congestion, hyperplasia, and swelling of the nasal mucosa, as well as hypertrophy of the turbinates and tonsils, making the respiratory tract unobstructed. Often, the nose is congested and breathing can only be assisted by opening the mouth.
So, don't fall asleep like you're sleeping soundly, go to the ear, nose, and throat department for examination in a timely manner.
Especially, breathing through the mouth while sleeping may be a warning signal for maxillary sinus cancer. If it's not taken seriously, delaying the condition won't be enough time to regret it.
It is worth mentioning that some infants and young children may experience abnormal nasal ventilation due to adenoid hypertrophy, resulting in mouth breathing, especially during sleep
Normally, as a child ages, the adenoids gradually shrink, and this situation will gradually disappear.
But parents should pay attention that if their child is breathing with their mouth open while sleeping, accompanied by symptoms such as snoring and hearing loss, they should seek medical treatment in a timely manner. Otherwise, long-term oral breathing may affect the child's appearance and growth, and may even cause sleep disorders or breathing pauses.
In addition, enlarged tonsils and allergic rhinitis are also common causes of children's oral breathing. Parents should be very vigilant and take their children to seek medical attention in a timely manner.
2、 Drooling while sleeping
It is rumored that drooling during sleep is a warning signal for stroke.
To be precise, drooling is one of the precursors of a stroke, but it is often accompanied by symptoms such as tilted eyes and mouth, dizziness, and headache.
In fact, there are many reasons for drooling during sleep, such as:
1. Improper sleeping posture
Sleeping in a prone or lateral position can cause the head to tilt and the mouth to be compressed and open, resulting in saliva flowing out. This situation can be avoided by correcting the posture and sleeping flat.
2. Oral problems
When inflammation occurs in the gums, periodontium, or tongue, it stimulates the secretion of salivary glands and leads to increased saliva.
In addition, people with anterior teeth deformities find it difficult to fully cover their lips while sleeping, and their upper and lower lips often separate naturally, making it easy for them to drool.
For the above situations, it is recommended to seek medical attention at the hospital's dental department to reduce adverse stimuli.
3. Open mouth breathing
When the nose is not unobstructed and you need to open your mouth to breathe, it is also easy to drool. It's best to go to the ear, nose, and throat department for a look.
4. Neuroregulatory disorders
The regulation of saliva secretion is entirely neuroreflexive. When the autonomic nervous system is disrupted, gastrointestinal peristalsis increases, and the secretion of saliva and other digestive fluids increases. After falling asleep, the swallowing movement is relatively reduced or stopped, and drooling may occur during sleep.
In addition, when dreaming of delicious food or frequently grinding teeth while sleeping, it stimulates the neural center of the brain and can also lead to increased saliva secretion, causing drooling during sleep.
5. Drug factors
When taking certain medications such as acetylcholine and pilocarpine, saliva secretion increases and drooling occurs during sleep.
In short, for drooling during sleep, there is no need to make random guesses. You can treat it according to your own situation. If necessary, it is necessary to promptly go to a regular hospital for examination and treatment.
Alright, after saying so much, I believe everyone understands that taking a nap is not only beneficial to the body, but also reminds everyone that there may be some abnormal phenomena during sleep, which may indicate that there is a problem with the body!
Therefore, it is recommended that friends who have the conditions take a nap in the afternoon. However, it should be noted that although taking a nap is good, everyone cannot be too sleepy!
Taking a nap for too long can lead to increased fatigue and illness
Taking a long nap can cause a series of physical discomfort——
Affects normal sleep at night, and even leads to or exacerbates insomnia;
The human body usually enters deep sleep half an hour after falling asleep, which is the stage of central nervous system suppression. The blood flowing through brain tissue is relatively reduced, muscles are in a relaxed state, and metabolic processes in the body are relatively reduced. If you wake up at this stage and the inhibition of the cerebral cortex is not yet relieved, you are prone to symptoms such as dizziness, dizziness, overall discomfort, increasing fatigue as you sleep;
Affect the normal metabolism of the body, lead to abnormal glucose metabolism, etc., and induce diabetes;
A study released at the 2020 European Cardiovascular Conference also found that taking a nap for more than an hour increases the risk of death by 30% and cardiovascular disease by 35%.
Suggestion: It is advisable to take a nap for 20-30 minutes.
In addition to the duration of the nap, everyone also needs to pay attention to their sleeping posture during the nap.
Attention: Do not sleep on your stomach, otherwise it may cause dizziness, dizziness, brain swelling and fatigue, numbness and pain in both arms and hands, lower back pain and neck pain, etc. Over time, it may also lead to cervical spondylosis, intervertebral disc herniation, etc.
In fact, lying flat or on one's side is the most ideal nap position.
Suggestion: Buy a folding lounge chair and sleep while lying down. If conditions do not allow, you can buy a U-shaped pillow to rest on your neck and sleep on the back of the chair.
