As respiratory illnesses surge this winter, there’s one symptom many patients hope will just go away: the dreaded cough.

“At this time of year, many people suffer from minor coughs due to common colds, allergies or sinus irritation with post-nasal drip,” Dr. Whitney Hardy, family medicine physician at Ochsner Health in New Orleans, Louisiana, told Fox News Digital.

One of the most common causes of a nagging cough is known as post-nasal drip, which occurs when the insides of the nasal passages become congested.

Often, this stems from a viral infection or an allergy trigger, according to the American Lung Association’s website.

Eventually, the nasal discharge drips to the back of the throat, causing the body to cough reflexively.

In some cases, coughs can be very debilitating, but in other cases they can resolve on their own without affecting daily activities — so it’s not always easy to know when to seek medical attention.

Here’s what the experts say you should know.

Why do we cough?

“A cough is a natural reflex in response to things like excess moisture in the lungs, foreign objects and mucus-producing infections,” Hardy told Fox News Digital.

After the irritant tickles the throat or airways, it sends a message to the brain that there is something in the body that shouldn’t be there, according to Mayo Clinic’s website.

The brain then sends a message to the chest muscles to cough in order to get the irritant out of the body.

It’s natural for people to cough from time to time — but if the symptom becomes severe or persists for too long, it can irritate the lung and induce even more coughing.

Too much coughing can lead to trouble sleeping, dizziness, headaches, vomiting, fainting, chest pain and even broken ribs, Mayo Clinic noted.

“This mechanism is important when we have an active infection and need to remove pus or fluid that will create further damage in the lung if it persists,” Dr. Baljinder S. Sidhu, a pulmonologist and sleep specialist who is the partner of Pacific Coast Critical Care Group in Southern California, told Fox News Digital.

“Lingering cough is often caused by irritated lung mucosa with minimal triggers.”

What are the different types of coughs?

A cough that lasts less than three weeks is known as an acute cough, per Mayo Clinic.

“An acute cough typically occurs with a viral or bacterial infection, such as the flu or pneumonia,” Hardy said.

“Sometimes, this type of cough can last up to three weeks, even after infection symptoms clear,” she added.

“Acute coughs are dry and get worse during the day, but almost completely stop at night.”

Lung irritants such as smoke, dust and chemicals are also common causes of an acute cough.

A subacute cough lasts between three and eight weeks, and often occurs after a lingering respiratory infection, experts say.

Always see a doctor if your cough lasts for more than eight weeks, as it may be necessary to get a chest X-ray to help diagnose the cause, according to the American Lung Association. (iStock)

A cough lasting for more than eight weeks is known as a chronic cough, according to the American Lung Association.

Asthma, gastroesophageal reflux disease (GERD) and a blood pressure medication known as lisinopril can all lead to a chronic cough.

Some life-threatening conditions, such as lung cancer and heart failure (where fluid from the heart backs up into the lung), may also cause a chronic cough, experts warned.

“Most coughs associated with a recent cold or viral illness will resolve on their own without additional treatment,” Liz Husted, M.D., a family medicine physician at Mayo Clinic Health System in La Crosse, Wisconsin, told Fox News Digital.

“A cough after a viral illness can commonly last up to six weeks; typically, no additional treatment is needed.”

When does a cough become worrisome?

“A cough is always a concern when accompanied by shortness of breath or chest pain,” Husted said.

“This is to be evaluated by a physician right away.”

Regardless of how long your cough lasts, experts recommend seeing a doctor if you experience severe cough, fever, difficulty breathing or wheezing.

Phlegm with pus (thick green discharge) or blood, chills, night sweats and weight loss are other red flags that indicate the need for medical attention.

Should you use home remedies?

Over-the-counter (OTC) cough medicines are safe for adults to take for acute coughs, as long as the cough is not associated with any worrisome symptoms, according to experts. (Check with your doctor to be sure.)

“These over-the-counter medications are usually a combination of several medications, including dextromethorphan, guaifenesin, phenylephrine and/or Tylenol,” Sidhu said.

Dextromethorphan is a cough suppressant that acts directly on cough receptors, the doctor noted.

Guaifenesin works by making mucus thinner and easier to bring up so that less irritant is left behind.

“Phenylephrine is a decongestant that helps treat nasal congestion and postnasal drip,” Sidhu said.

Parents or caregivers should check with their pediatrician first before administering cough medications to children, experts advise.

Also, OTC medications only treat the symptoms — not the underlying cause.

Past research has shown that they are no more effective than placebo medications in treating coughs.

“To help with an ongoing cough, use of a humidifier is recommended to keep plenty of moisture in your immediate atmosphere,” Hardy added.

Just 5 minutes of prayer could have surprising health benefits, study finds

NEWYou can now listen to Fox News articles!

Adult patients experienced significant relief from pain and anxiety after just five minutes of in-person prayer, as found in a randomized controlled trial.

The study, led by researchers at the University of Maryland School of Medicine’s Department of Family and Community Medicine, compared the effects of direct prayer to the effects of listening to music, revealing that prayer provided greater and more sustained relief for both symptoms.

“Prayer is powerful and beneficial on many levels,” Jesse Bradley, pastor of Grace Community Church in Washington, told Fox News Digital.

According to statistics cited in the study, prayer is the most used form of complementary medicine in the United States, relied on by 43% of Americans.

The researchers focused on a practice known as proximal intercessory prayer (PIP), which is defined as in-person, face-to-face prayer directed toward another individual’s well-being.

The researchers tracked changes in the participants’ self-reported pain and anxiety levels at multiple intervals: immediately after the five-minute session, at two weeks and at six weeks. (iStock)

The research team recruited 180 adult patients from a family medicine waiting room, according to a press release. All participants had previously reported experiencing moderate to severe pain, anxiety or both.

Following their standard medical appointments, the patients were randomly assigned to one of two groups: the prayer group, in which participants received five minutes of in-person Christian prayer delivered by a trained volunteer, and the music group, where they spent five minutes listening to music.

The researchers then tracked changes in the participants’ self-reported pain and anxiety levels at multiple intervals: immediately after the five-minute session, at two weeks and at six weeks.

“It was very well-received,” Katherine Jacobson, MD, assistant professor of family and community medicine at the University of Maryland School of Medicine, told Fox News Digital. She noted that 97% of participants said they were “neutral or supportive” when asked about having this kind of prayer available as part of their medical visits.

The study, which was published in The Annals of Family Medicine, revealed that while patients in both groups showed improvements, those in the prayer group reported substantially greater relief.

Bradley, who was not involved in the study, described the transformative power of prayer through “healing and comfort,” and shared that he himself once went through a long, painful recovery process.

“Daily prayer was essential in my healing journey,” he shared.

For pain reduction, the individuals who received in-person prayer experienced greater drops in pain intensity immediately following the session. This superior level of relief remained evident during the two-week follow-up compared to the music group, the researchers found.

For anxiety reduction, the benefits of prayer were even longer-lasting. The prayer recipients reported significantly greater reductions in anxiety immediately after the session, and these positive effects remained statistically significant at both the two-week and six-week checkpoints.

“We expected that patients who expected prayer to work would benefit more, but that wasn’t what we found,” Jacobson said.

“Religious affiliation, religious intensity and expectancy of healing did not predict who improved,” he went on. “Benefits appeared across a wide range of patients, including those not of the Christian faith and those who did not expect the intervention to help them.”

The study had some limitations, the researchers acknowledged, primarily that it could not prove that prayer itself caused the improvements.

The team also noted that patients receiving prayer had human contact, while the music control group did not. The eye contact and gentle laying of hands from the prayer volunteers may have had an impact, as that type of contact is known to reduce pain.

The researchers suggested that PIP could serve as a low-cost, non-pharmacologic and effective complement to standard medical care. (iStock)

The authors hope to conduct future studies with a control group that receives interpersonal contact but no prayer.

“For physicians and health systems, the study supports continuing to ask patients about spiritual care preferences as part of whole-person care, and considering whether trained Christian volunteer prayer practitioners could be integrated into outpatient settings for interested patients,” Jacobson said.

Rather than replacing traditional treatments, the authors indicate that this type of brief, faith-based intervention could be integrated into primary care settings to help manage pain and anxiety.

Cancer survivors may see surprising benefits from one specific exercise, study says

Cancer survivors may see surprising benefits from one specific exercise, study says

NEWYou can now listen to Fox News articles!

For many, surviving cancer comes with an automatic new lease on life but other survivors continue to experience physical and emotional challenges long after treatment ends.

Yoga may significantly reduce the insomnia, fatigue and mood disturbances many survivors endure after remission, a recent clinical trial found.

Mood disturbance and insomnia are “two of the most pervasive and troubling side effects experienced by cancer survivors for years after completing adjuvant treatments,” the researchers reported in the Journal of Clinical Oncology.

They noted that both symptoms can substantially inhibit survivors’ ability to perform everyday activities.

The study, funded by the National Cancer Institute, compared 204 cancer survivors receiving standard survivorship care alone with 206 survivors who paired standard care with the Yoga for Cancer Survivors (YOCAS) program. Most of the participants were female breast-cancer survivors.

YOCAS is a four-week intervention that incorporates two types of yoga – hatha, which is traditional and more active, and restorative, which is more passive. Both forms involve slow, gentle movements, breathing exercises and mindfulness, according to the American Society of Clinical Oncology (ASCO), which published a news release on the study’s findings.

Participants in the YOCAS group practiced yoga, on average, for 180 minutes each week over the course of three sessions.

At the end of the trial, the YOCAS participants reported overall improvements to mood, anxiety and fatigue, while the standard care group did not.

“Additionally, improvements in insomnia stemming from YOCAS yoga may be mediated by changes in overall [mood disturbance] and fatigue,” the researchers wrote.

“[The study is] an important advance because it offers survivors, who are likely already managing multiple medications, a non-pharmaceutical solution for reducing four different side effects at once,” Fumiko Chino, MD, a cancer researcher and associate professor in breast radiation oncology at MD Anderson Cancer Center, told ASCO.

Timothy Pearman, Ph.D., director of supportive oncology at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University, told Fox News Digital he was not surprised by the results of the study.

“Yoga is one of the most widely studied and validated interventions for managing cancer-related fatigue, mood disturbance and overall physical health,” Pearman said.

Pearman said his wife, Jenny Finkel, is a yoga teacher and received her continuing education at Duke University’s integrative medicine program, which focuses on yoga for cancer patients. 

“There are now a number of cancer-specific yoga teacher training programs nationwide,” Pearman said. “Yoga is a wonderful thing because it is very modifiable, meaning that even for people who have significant physical impairment, the exercises can be modified so that anyone can participate.”

He added that yoga is affordable, too, because “all you need is a mat and someone to show you how to do it.”

Osteoporosis, an increased risk of cardiac problems and issues with balance and stamina are other physical symptoms related to cancer treatment that yoga can help mitigate, Pearman said.

Shari Botwin, a licensed clinical social worker based in Pennsylvania, is a thyroid-cancer survivor who specializes in working with victims of trauma, including cancer. She turned to yoga months after her diagnosis and told Fox News Digital the practice has been “transformative.”

According to Botwin, cancer survivors she’s worked with have dealt with emotional challenges that affect their healing process, including depression and survivor’s guilt. In addition to the physical relief yoga can provide, she said it can also offer “a supportive environment of peers, some of which are cancer thrivers.”

Botwin added that yoga can help survivors who have lost parts of their body reframe their thinking.

“It supports us into moving into a place of self-compassion rather than shame and self-hatred,” she said.

Almost any type of exercise can be beneficial for cancer survivors, Pearman said. He advises his patients to stick to the type of exercise they enjoyed prior to cancer.
