Analysis and Review of Fox News Health Article: “Can’t Stop Clearing Your Throat? A Doctor Explains Why — and How to Fix It”
The Fox News Health article titled “Can’t Stop Clearing Your Throat? A Doctor Explains Why — and How to Fix It” provides an informative overview of chronic throat clearing, its potential causes, and suggested remedies. The piece features insights from Dr. Inna Husain, a laryngologist at Powers Health in Munster, Indiana. citeturn0search0
Content Summary
The article delves into several key aspects of chronic throat clearing:
- Physical Impact: Repeated throat clearing can lead to vocal fold damage, including lesions, nodules, bruising, and hemorrhages. citeturn0search0
- Potential Causes:
- Laryngeal Pharyngeal Reflux (LPR): Also known as “silent reflux,” this condition involves stomach contents rising into the throat, causing inflammation without typical heartburn symptoms. citeturn0search0
- Allergies and Inflammation: Conditions like sinusitis can lead to throat irritation.
- Vocal Cord Issues: Aging and other factors can thin vocal folds, making them more sensitive.
- Other Factors: Asthma, tracheal narrowing, and certain medications may contribute to throat clearing. citeturn0search0
- Cycle of Throat Clearing: The article explains how chronic throat clearing can become a self-perpetuating cycle, where the act itself causes further irritation, leading to more frequent clearing. citeturn0search0
Strengths
The article effectively raises awareness about a common yet often overlooked issue. By consulting Dr. Husain, the piece gains credibility and offers readers professional insights. The explanation of the vicious cycle associated with throat clearing is particularly enlightening, helping readers understand the importance of addressing the root causes rather than merely the symptoms.
Areas for Improvement
While the article identifies potential causes and the negative impact of chronic throat clearing, it could benefit from providing more detailed strategies or treatments to address the issue. Information on diagnostic approaches, lifestyle modifications, or therapeutic interventions would enhance the article’s practical value for readers seeking solutions.
Conclusion
Overall, the Fox News Health article serves as a concise and informative piece on chronic throat clearing. It successfully highlights the significance of the issue and its potential causes. Incorporating more actionable advice would further empower readers to take proactive steps toward managing and alleviating chronic throat clearing.

A recent study published in Nature has provided compelling evidence that the shingles vaccine may significantly reduce the risk of developing dementia in older adults. Conducted by researchers at Stanford University, the study analyzed health records of over 280,000 individuals in Wales, revealing that those who received the shingles vaccine were 20% less likely to develop dementia over a seven-year period compared to those who did not receive the vaccine. citeturn0news0
Study Design and Findings
The researchers capitalized on a unique public health policy in Wales that, starting from September 1, 2013, offered the shingles vaccine Zostavax to individuals born on or after September 2, 1933. This created a natural experiment, allowing for a quasi-randomized comparison between those eligible and ineligible for the vaccine. The analysis indicated a 20% reduction in dementia risk among the vaccinated group, with the strongest protective effect observed in women. citeturn0news0
Potential Mechanisms
While the exact mechanisms by which the shingles vaccine may confer protection against dementia remain unclear, several hypotheses have been proposed:
- Reduction of Neuroinflammation: Preventing the reactivation of the varicella-zoster virus may reduce inflammation in the nervous system, a factor implicated in dementia development. citeturn0news0
- Immune System Modulation: The vaccine might induce broader immune responses that offer neuroprotective benefits. citeturn0news0
Broader Context and Implications
This study adds to a growing body of research suggesting a link between viral infections, particularly those caused by herpes viruses like varicella-zoster, and an increased risk of dementia. For instance, other studies have indicated that infections such as influenza and skin infections may contribute to cognitive decline by causing greater brain volume loss, especially in regions critical for memory. citeturn0news8
The findings have significant public health implications. Dementia affects over 55 million people globally, and identifying modifiable risk factors is crucial for prevention strategies. The potential of the shingles vaccine to serve as a cost-effective intervention for reducing dementia risk is particularly noteworthy. citeturn0news0
Future Directions
Given the observational nature of the study, further research is necessary to establish a causal relationship between shingles vaccination and reduced dementia risk. Randomized controlled trials and studies involving the newer Shingrix vaccine are warranted to confirm these findings and explore the underlying mechanisms. Pharmaceutical companies, such as GSK, are already undertaking studies to examine whether their shingles vaccine lowers dementia risk. citeturn0news6
Conclusion
The study provides robust evidence supporting the potential of the shingles vaccine in reducing the risk of dementia. While more research is needed to fully understand the mechanisms and confirm causality, these findings offer a promising avenue for dementia prevention strategies. Individuals, particularly older adults, may consider discussing shingles vaccination with their healthcare providers as part of a comprehensive approach to maintaining cognitive health.
