Sunny with a chance of sneezing – I’m building a tool to forecast pollen levels that will help allergy sufferers know when it’s safe to go outside

Do flowers blossoming in spring make you miserable? Are you sworn enemies with fall bloomers like ragweed? If you suffer from pollen allergies, imagine the usefulness of a reliable pollen forecast that could help you manage your symptoms by providing an early warning when pollen conditions are bad.
We’re working on it! As an atmospheric scientist, I study the weather, climate and anything in our Earth’s atmosphere, including pollen. One in three people in the U.S. suffer from allergic rhinitis, otherwise known as “allergies,” and pollen is the most common cause.
While allergic rhinitis is not curable, its symptoms can be successfully treated. Two main methods are medication and pollen avoidance. They both rely on knowing when, where and how much pollen is, and is expected to be, in the air. Many medications work best if taken before symptoms occur. Advance knowledge of pollen allows allergy sufferers to change plans in order to minimize their exposure to pollen.
My colleagues and I are pulling together what we know about how plant biology and meteorology affect the amount of pollen in the air, along with pollen count numbers, to build a reliable pollen forecast.
Counting pollen grain by grain
Allergic symptoms tend to be more severe the higher the concentration of airborne pollen. The amount of pollen in the air is constantly changing, so it would be ideal to monitor pollen in populated areas at regular frequent intervals. In the U.S., the National Allergy Bureau collects, processes and distributes daily pollen concentrations from stations around the country.
Unfortunately, there are fewer than 90 active stations. Of these, many do not count on weekends or outside of the main pollen season. Part of the reason is that these are volunteer-run stations, and pollen monitoring requires significant time and resources.
Pollen is collected using a machine that sucks in air and traps pollen on sticky tape. A trained technician then processes, identifies and counts the tiny pollen grains under a microscope. During the height of pollen season, it may take a few hours for a technician to count the day’s pollen. Automated pollen monitoring systems do exist and would greatly reduce the need for human resources. But for now, these systems are either extremely expensive or have not been evaluated for accuracy.
Building a forecasting model
Pollen that causes allergic reactions is from anemophilous or wind-pollinated plants. Pollen grains contain the male sperm from the plant, an essential component of plant reproduction. Anemophilous plants produce a lot of pollen because they rely on the whims of the wind to carry it to reach the female counterparts of their species to reproduce and grow new plants. The amount of pollen in the air has been rising because climate change is lengthening the pollen season and increasing how much pollen gets produced.
Since we have access to only a limited amount of pollen count data, my colleagues and I leverage what we know about the environment to estimate the amount of pollen in the air. Generally warm, sunny, dry and windy days are correlated with high airborne pollen concentrations, and rainy and humid days with low concentrations.
Plants depend on water and sunlight to grow. The timing of precipitation, temperature and solar radiation can affect a plant’s development and its readiness to flower. Once the plant is ready to flower, environmental variables can determine when pollen is released, how far it travels and how long it remains in the air.
The pollen model my colleagues and I have developed uses these known relationships between meteorology and pollen to estimate airborne pollen. We also include satellite images of vegetation in the model because satellites can detect greening and provide an estimate of the beginning of spring.
Our model can forecast pollen 1 to 14 days in advance for locations where there are pollen stations. But due to the sparsity of pollen stations, we are working on extending the model to forecast in locations with no pollen counts. In those places we use nearby pollen station data, along with localized meteorology, to estimate the pollen.
Although pollen reporting and forecasts do exist in the popular media, their pollen reports differ from observations, and their forecasts are limited only to categories of trees, grasses and weeds. Our forecast can predict for specific pollen types because our model includes information about how each plant type interacts differently with the environment.
A fine-tuned forecast in your pocket
We are collaborating with medical professionals and health scientists to understand the pollen levels associated with increasing severity of allergic symptoms. Our plan is to tailor the forecast to allow patients to better manage their symptoms.
So far, we can accurately forecast for four of the most abundant pollen types in the U.S. only in locations with pollen stations. We are seeking funding to expand to other pollen types and other locations, and we are working on creating a platform to automate the data processing and run the forecast.
Ultimately, we want to provide a forecast every day during pollen season to give allergy sufferers the information they need to manage their symptoms. Allergies are often undertreated and knowledge about self-care is limited, so a reliable pollen forecast that is easy to access – for example via an app on your phone – along with education on allergy management, could really help allergy sufferers.

(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.
