Seasonal allergies may increase suicide risk – new research
Research indicates that seasonal allergies may heighten suicide risk, with deaths by suicide increasing by 5.5% on moderate pollen days and 7.4% on high pollen days. The study suggests allergies exacerbate existing mental health vulnerabilities. Addressing allergy symptoms and enhancing pollen monitoring could help mitigate these risks, especially in vulnerable populations.
Seasonal allergies may increase suicide risk – new research
Shooshan Danagoulian, Wayne State University
Seasonal allergies – triggered by pollen – appear to make deaths by suicide more likely. Our findings, published in the Journal of Health Economics, show that minor physical health conditions like mild seasonal allergies, previously thought not to be an immediate trigger of suicide, are indeed a risk factor.
To evaluate the link between seasonal allergies and suicide, my co-authors and I combined daily pollen measurements with daily suicide counts across 34 U.S. metropolitan areas.
Because both pollen and suicide are sensitive to weather conditions, we carefully accounted for temperature, rainfall and wind. We also controlled for differences in local climate and plant life, since pollen levels vary by region, and for seasonal averages that might otherwise obscure results. This allowed us to compare suicide counts on days with unexpectedly high pollen to days with little or none in the same county.
The results were striking. Relative to days with no or low levels of pollen, we found that deaths by suicide rose by 5.5% when pollen levels are moderate and 7.4% when levels are high. The increase was even larger among people with a known history of mental health conditions or treatment. We also showed that on high-pollen days, residents of affected areas experience more depressive symptoms and exhaustion.
Our analysis suggests that allergies exacerbate existing vulnerabilities, pushing some people toward crisis. We suspect that sleep disruption is the link between allergies and suicide rates.
Why it matters
More than 80 million Americans experience seasonal allergies each year.
Symptoms include sneezing, congestion, itchy eyes and scratchy throat. Most people experiencing these symptoms feel sluggish during the day and sleep poorly at night. Allergy sufferers might not realize, however, that these symptoms reduce alertness and cognitive functioning – some of the factors that can worsen mental health and increase vulnerability to suicidal thoughts and behaviors.
Suicide rates have been growing steadily in the past two decades, by 37% between 2000 and 2018. According to the Centers for Disease Control and Prevention, more than 49,000 Americans died by suicide in 2022, and over 616,000 visited emergency departments for self-harm injuries.
Although socioeconomic and demographic factors are the most important predictors of suicide, much less is known about its short-term triggers. Our study adds to growing evidence that the environment – including something as natural as pollen – can influence mental health risks.
This issue is likely to become more urgent as the climate changes. Rising temperatures lengthen pollen seasons and increase pollen volume. Over the past two decades, pollen seasons have grown in both intensity and duration, and projections suggest they will continue to worsen.
That means more people will experience stronger allergy symptoms, with ripple effects not only for physical health but also for sleep, mood and mental well-being.
What we still don’t know
Despite the scale of the problem, there are no national systems in the U.S. to consistently measure and communicate pollen levels. Most communities lack reliable forecasts and alert systems that would allow vulnerable people to take precautions. This gap limits both prevention and research.
Our study focused on metropolitan areas where pollen and death counts were available, but we cannot yet generalize to rural areas. That is a concern because rural communities often face greater shortages in mental health care and pharmacy access – and have seen rising suicide rates over the past decade.
What’s next
For people who are already receiving mental health care, recognizing and treating seasonal allergies is a key part of self-care.
Over-the-counter medications can be highly effective at reducing symptoms.
More broadly, people should be aware that during peak allergy season, reduced alertness, sleep disruptions and mood fluctuations may place an increased burden on their mental health, in addition to the allergy symptoms.
In terms of policy, improving pollen monitoring and public communication could help people anticipate high-risk days. Such infrastructure would also support further research, particularly in rural areas where data is currently lacking. Our next step, supported by the American Foundation for Suicide Prevention, is to examine the impact of pollen on rural communities.
The Research Brief is a short take on interesting academic work.

(Feature Impact) Dry eye is one of the most overlooked symptoms of perimenopause, the phase of fluctuating hormones leading up to a woman’s final period, and menopause, the point in a woman’s life when she’s gone a year without a period.
In fact, 79% of women1 recognize hot flashes as a symptom of menopause, but only 14% recognize dry eye as a menopause-related symptom, according to the 2026 Bausch + Lomb (Peri)Menopausal Survey. What’s more, 78% of women1 were surprised to learn that dry eye is a symptom of perimenopause or menopause.
“Dry eye is still widely overlooked as a symptom of menopause, and many women think it’s just a minor nuisance, but the truth is it can significantly affect your daily life,” said Neda Gioia, OD, CNS, IFMCP, FOWNS, founder, Integrative Vision. “Early symptoms are often misunderstood or self-treated but it’s very important for women who experience symptoms to see an eye doctor and get an accurate diagnosis and treatment.”
During perimenopause and menopause, declining hormone levels can impact tear production, tear quality and tear evaporation, contributing to dry eye symptoms including redness, fluctuating vision and a gritty or tired feeling in the eyes, all of which can impact day-to-day comfort and quality of life. If left untreated, dry eyes may worsen over time, potentially impacting eye health and vision. Among peri-, menopausal and post-menopausal women who experienced dry eye, 80% said the symptom came as a surprise.
Respondents reported their dry eye symptoms caused difficulty reading (58%), difficulty using screens (53%), difficulty driving (26%) and reduced productivity (17%), underscoring the often-overlooked impact dry eyes can have on everyday life.1
However, there are a variety of products and treatment approaches available to help manage dry eye symptoms. For example, Bausch + Lomb offers a range of options designed to address the main causes of dry eye.
A doctor-recommended, clinically proven once-daily soft gel supplement that targets the key root causes of dry eyes, Blink NutriTears supports healthy tear production and provides lasting, continuous relief.* § As part of a comprehensive approach to dry eye management, the supplement can be used with Blink Triple Care Preservative Free Lubricant Eye Drops, which are designed to directly address tear evaporation, one of the leading causes of dry eye, and provide instant and long-lasting symptom relief.
An eye care professional can help determine the approach that’s right for each individual.

The Oral and Cardiovascular Health Connection: 4 Tips to Protect Your Teeth, Gums and Heart
People often think of dentists and doctors as totally separate healthcare professionals: one cares for your teeth and mouth while the other handles the rest of the body. In reality, the different systems in the human body are closely interconnected and oral health is no exception, making dentists a vital part of your healthcare team. Care for your teeth, gums and heart all at once using these tips.
(Feature Impact) People often think of dentists and doctors as totally separate healthcare professionals: one cares for your teeth and mouth while the other handles the rest of the body. In reality, the different systems in the human body are closely interconnected and oral health is no exception, making dentists a vital part of your healthcare team.
Oral health and heart health have a particularly close connection, with inflammation at the core of it. When your gums are inflamed, the resulting bacteria can make their way from your mouth through your bloodstream, potentially contributing to your blood vessels constricting or becoming blocked. This, in turn, may force your heart to work harder and raise your blood pressure, putting you at risk of heart disease and stroke. More than 46% of adults in the U.S. have high blood pressure, and more than 40% of adults age 30 and older are affected by periodontal (gum) disease.
To help address these issues, the American Heart Association’s Healthy Smiles, Healthy Hearts initiative, in collaboration with Delta Dental of California, is encouraging dental teams to take a total-body perspective with their patients. Simple steps like blood pressure screenings during checkups can give a more complete picture of a person’s overall health. If a member of your dental care team pulls out a blood pressure cuff at your next appointment, it’s a good sign.
“The mouth is a gateway to the body and can often reveal more about your total body health than you may think,” said Daniel Croley, D.M.D., chief dental officer at Delta Dental of California and Affiliates. “Oral health professionals have a powerful opportunity to integrate more into their patients’ collective health care team beyond protecting their patients’ teeth By connecting oral health and heart health, this initiative helps dentists identify risks early and guide patients toward care that can improve and even save lives.”
Care for your teeth, gums and heart all at once using these tips from experts at the American Heart Association.
Follow a Brushing and Flossing Schedule
Good dental health starts with a daily routine. If you don’t want to sheepishly cringe next time the dentist inquires about yours, brush at least twice a day and floss at least once a day to disrupt plaque-forming bacteria. Dentists recommend using toothpaste with fluoride and brushing your teeth and gums thoroughly yet gently, as applying too much pressure can wear away enamel and cause gum recession.
Eat a Healthy Diet and Limit Sugar
Most kids are used to hearing sugar will rot their teeth – and that’s not just a parental scare tactic to get their little hands out of the candy jar. Sugar feeds harmful bacteria in your mouth, producing acid that can cause cavities and gum disease. For a diet your heart and teeth will both appreciate, prioritize vegetables, lean proteins, complex carbohydrates and healthy fats, while limiting added sugars and refined carbohydrates.
Avoid Smoking and Tobacco Products
The connection between smoking and oral disease is well established: smokers face significantly higher risks of developing periodontal disease, losing teeth or being diagnosed with oral cancer. Cigarettes aren’t the only form of tobacco to worry about, either. Vaping, dipping and chewing tobacco can also harm your dental health by drying out your mouth and restricting blood flow to the gums. Since these products are also harmful to heart health, quitting or avoiding them offers plenty of worthwhile benefits. Seek support if you need help to kick the habit.
Communicate with Your Healthcare Team
Since your body’s systems are connected to each other, it’s helpful to talk to your dentist about your blood pressure and to your doctor about your oral health. Start thinking of your dentist as a key member of your integrated healthcare team. Don’t be afraid to share your medical history, discuss the side effects of any medications you’re taking and ask for personalized recommendations on caring for your teeth, gums and overall health.

5 Habits to Boost Immunity During Cold and Flu Season
(Feature Impact) Your immune system is your strongest ally during cold and flu season, working hard to keep you healthy as you start hearing those telltale coughs and sneezes all around. Help your body do its job well by adopting a few simple habits that naturally support its ability to fight off germs or recover faster.
Talk to your healthcare provider for personalized advice then work on making these habits normal in your household.
Get Regular Exercise
Exercise is like a wonder drug that can improve nearly every aspect of health and wellness. Physical activity increases blood flow, reduces long-term inflammation, helps immune cells circulate through the body to guard against invaders and may even flush bacteria out of your lungs and airways. Plan to fit at least 150 minutes of moderate exercise into each week, like a bike ride, brisk walk, yoga class or on-demand video workout.
Eat Foods That Support Immune Health
To keep your immune system fueled, experts recommend eating a varied diet featuring plenty of fruits, vegetables, nuts, seeds, whole grains and healthy fats like olive oil. Consider adding fresh grapes to your diet to enjoy benefits from their naturally occurring plant compounds.
Protecting the body starts all the way down at the cellular level, and grapes contain powerful polyphenols that support the health and function of cells. Studies indicate certain compounds in grapes, like resveratrol and flavonoids, support immune system function as well as brain, skin, GI and heart health.
These little fruits are easy to add to your diet, whether you enjoy sweet, juicy Grapes from California by the handful or toss them in a blender to make this California Grape Wellness Juice recipe. Support multiple aspects of wellness with the drink’s powerful combination of fruits and vegetables, delivering a variety of immune-boosting vitamins, minerals and antioxidants.
Stay Hydrated
Drinking enough water helps clean your lymphatic system, which is responsible for producing special white blood cells that fight germs. It also keeps membranes in your nose and mouth moist, decreasing infection risk. If you struggle to drink enough, eating water-rich foods like grapes also helps you improve hydration.
Practice Good Germ Hygiene
To increase your odds of staying healthy during peak illness season, hearken back to the tried-and-true hygiene advice your parents might have tried to drill into your head as a kid. Regularly wash your hands with warm water and soap, avoid touching your face while out and about, keep your distance from symptomatic people and disinfect commonly used surfaces like doorknobs when someone in the house or office is sick.
Sleep More, Stress Less
Before you start feeling stressed that you aren’t getting enough sleep, rest assured there are easy changes you can make to support your well-being in both areas. Try switching up your nightly routine to be oriented less around screens and more around calming activities that actually help you wind down, like yoga, meditation or reading.
