The alcohol-exposed mice exhibited increased numbers of certain inflammatory cells (i.e., eosinophils) in fluid obtained from the lungs (i.e., bronchoalveolar lavage fluid), increased production of the main component of mucus (i.e., mucin), and constriction of the small airways (i.e., decreased bronchiole patency). This risk further is exacerbated by the negative effects of chronic alcohol ingestion on the lower airways. The mechanisms responsible for rendering people with alcohol use disorder (AUD) vulnerable to lung damage include alterations in host defenses of the upper and lower airways, disruption of alveolar epithelial barrier integrity, and alveolar macrophage immune dysfunction. Most studies examining alcohol’s oxygen lowering effects have looked at acute alcohol exposure rather than long-term effects of chronic drinking.
This connection is not always immediately apparent, but evidence confirms that alcohol directly and indirectly affects lung well-being. However, by practicing moderation, adopting healthy lifestyle changes, and seeking professional help when needed, individuals can take steps to protect and support their lung health. Remember, while these strategies can help protect your lung health, they are not a substitute for medical advice.
In contrast, Oldenburg and colleagues (2012) demonstrated that alcohol actually reduced airway hyperresponsiveness and airway inflammation in a mouse model of allergic asthma. These effects were not seen in mice that were exposed to alcohol but were not allergen sensitized, suggesting that alcohol can be an important trigger for airway reactivity in the context of an underlying allergic component. However, researchers have not yet been able to determine conclusively if alcohol ingestion has any clinically significant effects on asthma. Similar findings were seen in later studies that examined the effects of red wine in asthma (Dahl et al. 1986; Vally et al. 2000). These findings were the first to suggest that the nonalcohol components and additives of alcoholic beverages may be responsible for inducing asthma, rather than alcohol itself.

- Studies conducted by the Division of Metabolism and Health Effects at the National Institute on Alcohol Abuse and Alcoholism have shown evidence that drinking alcohol can increase inflammation throughout the body, beyond just the area of the lungs.
- Several years later Lange, in a larger and longitudinal population study from Copenhagen, examined 8,765 persons over five years with alcohol intake histories, smoking histories and pulmonary function tests (Lange et al., 1988).
- In contrast, prolonged exposure to high concentrations of alcohol desensitizes airway cilia to external stimuli and impairs airway clearance of bacterial pathogens.
Mechanism of alcohol-induced oxidative stress and neuronal injury. Arterial blood gas changes in acute ethanol intoxication. They also have altered brain chemistry modulating their response to alcohol. Acute experiments help identify alcohol’s direct toxic impacts.
Lung glutathione levels in the alcoholic subjects were approximately 80 percent lower than those of nonalcoholic subjects (Moss et al. 2000). Alcohol also is a risk factor for the development of scarring of the liver (i.e., cirrhosis), which can lead to increased pressure in the vein that carries blood to the liver (i.e., portal hypertension), and gastrointestinal hemorrhage, which may warrant multiple transfusions of blood products (Hudson et al. 1995), another risk factor for developing ARDS. Alcoholics have increased incidences and death from trauma (Anda et al. 1988), an increased severity of nonpulmonary organ dysfunction in septic shock (Moss et al. 2003), and an increased risk for aspiration (Berkowitz et al. 1973). In addition to increasing the risk for developing ARDS, alcohol abuse also makes it more likely that an individual will develop a critical illness that puts them at risk for ARDS in the first place.
Summary of Alcohol and COPD
Firstly, alcohol can directly damage lung tissue, leading to impaired lung function. Lipoprotein complex formed by alveolar cells that helps ensure the lungs’ ability to expand during respiration, regulate the size of the alveoli, and prevent fluid accumulation in the lungs; also plays a role in innate immunity of the lungs The what is a roofi layer of cells lining the surface of the respiratory tract that are covered by a thin layer of mucus and which carry cilia, whose rhythmic beating helps clear the airways Procedure where fluid is injected through a tube into a small airway of the lung and then collected and tested for the presence of bacteria and other compounds; the procedure is used to diagnose infections and other lung diseases Researchers and clinicians are just beginning to scratch the surface of this challenging problem, but the rapid pace of experimental and clinical research in the past two decades offers hope that in the relatively near future the devastating effects of AUD on lung health can be ameliorated.
Alcoholics exhibit tolerance and resistance to the respiratory slowing effects of acute alcohol. For instance, research shows the respiratory depressant effects of alcohol are far less pronounced in those with alcoholism due to adaptations. The body adapts to compensate for regular alcohol intake, so chronic effects may differ from acute ones. While blood flow to the brain may not be impaired, alcohol is believed to directly suppress oxygen utilization in brain cells through mitochondrial effects.
Secondly, alcohol consumption may impair judgment and decision-making skills, potentially leading to increased smoking. Alcohol and smoking can interact in several ways to increase the risk of lung damage. If you find that alcohol triggers or worsens your cough, it is advisable to limit or avoid alcohol consumption and consult with a healthcare professional for appropriate management. Alcohol can act as a respiratory depressant, slowing down the central nervous system and potentially impacting lung function. Understanding these connections is essential for individuals who consume alcohol and want to maintain their lung health.

The liquids help thin out the mucus in your lungs so it’s easier to cough up and out. In fact, some experts warn that heavy alcohol use may even contribute to a higher incidence of lung infections—the very lung infections that a person with COPD needs to avoid. Chronic obstructive pulmonary disease, or COPD, usually develops after a person has been exposed to a lung irritant for a long period of time. Excessive alcohol consumption might complicate the results of such tests. “Alcohol appears to disrupt the healthy balance in the lung,” said lead author Majid Afshar, MD, MSCR. They can help you understand the risks and develop a plan to protect your respiratory system.
The Importance of Moderate Alcohol Consumption
Drinking raises the risk of several types of cancer, including colon, liver, breast and mouth and throat. Moderate drinking was once thought to have benefits for the heart, but better research methods have thrown cold water on that. Ms Shore studies under the tutelage of Richard Morris, at the University of California Los Angeles, at international workshops, and with Nan Rae Parker at her Pasadena Studio. A few reports have suggested a possible benefit by light to moderate alcohol intake for COPD. Thus, the lesser likelihood of a low FEV1/FVC among never-smokers in our data (Table 4) indicates independence of the finding from confounding by smoking. These measurements were performed with equipment that was technically inferior to more modern lung-testing machines.
How Does Alcohol Affect the Respiratory System?
The mean FEV1/FVC ratio for all 177,721 study participants was 0.779, of whom 33,532 (18.9%) had a ratio 1/FVC ratios are presented in Table 2. Because adjusted models consistently showed similar alcohol relations for these measures and for the FEV1/FVC ratio, we present only data about the mean ratio in other tables. Unadjusted mean values for FEV1 and FVC for men and women are presented in Table 1, with evident higher values for light to moderate drinkers of alcohol.
- Fleisch’s findings extended an earlier report that very high concentrations of ethanol (2.4 % or 500 mM) inhibited antigen-induced histamine release from guinea pig lung tissue (Mongar and Schild, 1957).
- In healthy people there is relatively little TGFβ1 in the adult lung; instead, alveolar epithelial integrity and the function of alveolar macrophages are under the influence of GM-CSF.
- Taken together, these studies are the first to link mild alcohol intake to reduced risk for developing or dying from COPD, and are consistent with the controversial autopsy findings of Pratt three decades earlier (Pratt and Vollmer, 1984).
- One of the primary ways alcohol affects lung function is by impairing the process of oxygen exchange.
- In one study, the mortality rate of chronic alcohol users with ARDS was 62%.
Importantly, they noted that this adverse pulmonary association with alcohol intake remained strong when they restricted the analysis to men that had never smoked. They concluded that there is no evidence for an independent association of alcohol intake on airflow obstruction. Although unadjusted values indicated obstruction in heavy drinkers compared to light drinkers, the difference disappeared when adjustment was made for cigarette smoking, socioeconomic status, male sex and age. Airflow obstruction could not be accounted for on the basis of current smoking status or previous infection. Furthermore, combined exposure to smoke and alcohol was greater than either exposure alone suggesting a synergism between smoke and alcohol exposure and COPD.
Both clinical and experimental studies have detected increased oxidative stress in the alveolar space after alcohol exposure (Moss et al. 2000; Velasquez et al. 2002). The precise mechanisms by which alcohol impairs alveolar macrophage immune function have yet to be elucidated; however, several observations indicate that the macrophages are subjected to an altered environment characterized by oxidative stress and zinc deficiency. Taken together, these alcohol-mediated defects in alveolar macrophage function contribute to increased vulnerability to pulmonary infections. The alveolar macrophage what it feels like to be drunk is the primary immune cell in the alveolar space and is responsible for maintaining homeostasis of the lower airways through phagocytosis of pathogens and removal of debris. The mechanisms by which chronic and excessive alcohol consumption increases susceptibility to pneumonia are multifactorial. Additionally, recent studies have demonstrated that people who abuse alcohol are not only more likely to develop pneumonia, but also are susceptible to more severe forms of the disease, are more likely to experience complications, and require greater use of resources.
Non-alcohol congeners and alcohol metabolites act as triggers for airway disease exacerbations especially in atopic asthmatics and in Asian populations who have a reduced capacity to metabolize alcohol. The impact of alcohol on lung airway functions is dependent on the concentration, duration and route of exposure. The volatility of alcohol promotes the movement of alcohol from the bronchial circulation across the airway epithelium and into the conducting airways of the lung.
From weakening our immune system to increasing the risk of developing pneumonia, alcohol can have several negative effects on our respiratory system. Additionally, when combined with smoking, heavy drinking can significantly increase the risk of developing lung cancer. While alcohol itself is not a direct cause of lung cancer, heavy drinking can weaken the immune system and increase the risk of developing infections that can lead to lung cancer. When it comes to lung health, moderate alcohol consumption may not have a significant negative impact.
Using Fetal Alcohol Disorder a questionnaire, they queried 168 patients with known asthma from a chest clinic at four hospitals excluding asthmatics with cardiac disease, other pulmonary diseases and lifetime non-drinkers. At this point it is safe to say that our knowledge about the influence of inhaled alcohol on airway function is unsatisfactory. With AWOL alcohol is aerosolized through a nebulizer and has become fashionable in Europe and Asia as way to become intoxicated without the side effects of drinking (Press, 2004). An excellent review of alcoholic drinks as triggers for asthma has been previously published (Vally et al., 2000). Similar findings were obtained in another study that implicated the sulfur dioxide content in red wine as a likely trigger for bronchospasm in asthmatics rather than the alcohol itself (Dahl et al., 1986). Importantly, in three of these patients, drink-precipitated bronchospasm was not triggered by an oral ingestion of an equivalent amount of pure alcohol in water implicating the non-alcohol components of the beverage as the likely asthma trigger.
Alcohol alters airway mucociliary clearance, which is dependent upon the dose and duration of alcohol exposure. At this juncture, alcohol downregulation of airway ciliary PKA represents the most likely mechanism that causes alcohol-induced impairment of mucociliary clearance. Taken together, these studies fully recapitulated the in vitro findings of alcohol-desensitization of ciliary kinases. This same finding was reproduced in mice ingesting alcohol in their drinking water (Elliott et al., 2007). Rats fed alcohol for six weeks demonstrated slowed cilia beating and desensitization of airway PKA activity (Wyatt et al., 2004).
Allergies may be one cause, as alcoholic beverages contain histamines and sulfites, which can trigger asthma. Additionally, drinking water keeps your mucus membranes moist, which is essential for proper lung function. When you exercise, for example, your breathing rate increases, helping to circulate air throughout your lungs and improve their overall function. If you’re living with bronchiectasis or other chronic lung conditions, talk to your clinician about limiting your alcohol usage or avoiding it altogether. In some cases, coughing after drinking alcohol may also be a sign of an underlying condition, such as asthma or acid reflux, due to alcohol causing inflammation in the gut.12
