夜间一躺就咳，赶紧试试这几种方法！

Core Viewpoint - Nighttime cough is a common symptom that can be exacerbated by various factors, including body position, physiological changes, environmental conditions, and underlying diseases [3][4][5][6][7]. Group 1: Causes of Nighttime Cough - Body position can lead to airway collapse and accumulation of secretions, making it harder to cough effectively [3]. - Physiological changes at night, such as increased vagus nerve activity and decreased cortisol levels, can heighten cough sensitivity [3]. - Environmental factors like dry air and allergens in the bedroom can irritate the respiratory tract [3]. - Underlying diseases such as bronchitis and pneumonia can manifest as nighttime cough [3]. Group 2: Specific Conditions Associated with Cough - Asthma patients may experience increased airway sensitivity at night, leading to cough and difficulty breathing [4]. - Gastroesophageal reflux disease (GERD) can cause stomach acid to irritate the throat when lying down, resulting in cough [5]. - Upper airway cough syndrome, often due to conditions like rhinitis or sinusitis, can lead to post-nasal drip and cough [6]. - Cardiac-related cough is more common in older adults due to increased venous return when lying down [7]. Group 3: Remedies and Recommendations - Nasal irrigation can effectively alleviate cough caused by upper airway issues, particularly for those with chronic rhinitis or sinusitis [9]. - Wearing a mask while sleeping is not recommended due to discomfort and limited protective benefits [11]. - Home remedies like honey water and steamed oranges may provide temporary relief but should not replace medical treatment [12]. - Using cough suppressants without understanding the underlying cause can be counterproductive and delay proper treatment [13]. Group 4: Practical Tips for Relief - Adjusting body position to a semi-reclined posture can help alleviate cough, especially for those with nasal or reflux issues [13][14]. - Maintaining indoor humidity levels between 40%-60% can reduce respiratory irritation [16]. - Acupressure techniques on specific points may help relieve cough symptoms [17][19]. - Temporary measures like sipping warm water or using throat lozenges can soothe irritation [19].
