Why do asthma patients get worse at night and in the early hours of the morning?

Asthma is a relatively common disease, and I am no stranger to asthma as a medical student. Asthma worsens in the morning and evening, which is also a more obvious feature of asthma.

Asthma is a chronic <> characterized by nonspecific inflammation of the airways

Mast cells, as the main effector cells causing acute asthma, play a "trigger" role; Eosinophils are thought to be the main effector cells that induce airway inflammation in chronic asthma. Scientists have confirmed that eosinophil percentage and count are inversely proportional to FEV1. Studies have found that eosinophils in peripheral blood and sputum in patients with nocturnal asthma are significantly higher than those in normal people.

Therefore, asthma exacerbations at night may be caused by eosinophilia at night.

Some friends may not know much about asthma, so it is best for us to know the clinical symptoms of an asthma attack to avoid delays in the event of an asthma attack**.

Asthma presents with episodic cough, chest tightness, and difficulty breathing. Some patients cough up more sputum than when the attack tends to remission, and if there is no co-infection, it is often white and sticky sputum, tough, and sometimes rice-grained or mucus columnar. The severity and duration of the attack vary widely from chest urgency for a few minutes to extreme dyspnea for several weeks or longer.

Asthma patients should also pay attention to it, and sometimes a little inattention may induce or aggravate asthma.

Avoid colds that cause or worsen asthma, and try not to wear sweaters or other clothing that is prone to allergies. Keep asthma medication next to your bed before going to bed to prevent accidents caused by not being able to get it in time during an asthma attack. Try not to eat seafood on a regular basis as it may trigger asthma.

<> I personally feel that it has a lot to do with the main time of the twelve meridians, which is also an important part of the theory of traditional Chinese medicine, and the main time of each viscera meridian is as follows

The lungs are big and the stomach is in the palace, and the spleen and heart are not in the middle of the day.

Shen Yu kidney pericardium, Hai Sanzi gallbladder ugly liver Tong.

Let me explain to you, this is the 12 meridians and the earth, each meridian corresponds to the relevant viscera for the main cycle, the use of acupuncture is also called meridian flow injection acupuncture, in the corresponding time **, the effect will be better. The main time of the lung meridian is the yin hour, that is, from three o'clock to five o'clock, that is, in the early hours of the morning, that is, why do asthma patients love to get worse in the early hours of the morning, not only asthma has this discovery, but the time of angina pectoris attack also coincides with the main time of the pericardial meridian. I feel that the lung meridian itself is already very weak, and he will be more tired and panicked when he works during the main time, so asthma may occur.

The early hours of the morning are also the peak of the day, with the lowest temperatures. Asthma for a long time will inevitably hurt the kidneys, and the damage to the kidney qi will produce a syndrome in the theory of traditional Chinese medicine called the kidney not accepting qi syndrome, the kidney not accepting qi syndrome is because the kidney qi is damaged, and the breathing is shallow, and after the kidney qi is damaged, the yin qi is at its peak in the early morning, which is more likely to aggravate the degree of inadmissibility, so the disease is produced.

Sleeping at night is also the time of the day when a person's resistance is the weakest. That's why I have asthma.

Factors for the occurrence of asthma at night: 1. The vagus nerve is more worried during night sleep, the bronchial smooth muscle contracts and spasms, and the airway secretions increase. 2. The concentration of corticosteroids decreases at night, which is easy to trigger asthma attacks.

3. The airway reactivity at night is higher than that during the day, which increases the chance of nocturnal attacks. 4. Airway secretions increase at night, and it is difficult to exhale gas.

Asthma attacks are generally more common at night, because the body's vagus nerve is prone to excitation at night, resulting in spasm of bronchial smooth muscle, which in turn triggers bronchial contraction and asthma. The most critical thing is that bronchodilators need to be used to dilate the smooth muscles of the bronchial tubes in order to relieve asthma attacks.

Because the air at night is thinner, and the weather is cooler, it is easy to induce respiratory diseases, the room must be warmer, and personal warmth measures should be taken.

This is because asthma attacks are prone to when lying down, and the best thing to do is to take some related medications to relieve the symptoms during the attack.

At this time, you should drink the medicine urgently, and then breathe slowly, because this can have a better effect.

At this time, you must go to the hospital to receive **, be sure to take medicine, pay attention to the surrounding situation, and keep your breathing smooth.

Triggers for asthma attacks, active removal of triggers, corresponding anti-inflammatory**, inhaled or nebulized hormones. In more severe cases, intravenous corticosteroids can be used to fight inflammation**.
