Do Using Smart Rings Actually Help You Be Healthier?

Posted on February 13, 2026 by Patrick Hercules

Recently, technology has brought us fitness trackers and smart watches that can help us track our workouts, daily steps, and even monitor our sleep, stress, heart rate, and blood oxygen levels.

However, smart rings have become another way to track our health, and can be used to monitor movement, body temperature, sleep, heart rate, stress, as well as menstrual cycles.

Unlike smartwatches, smart rings don’t have screens to view these health metrics. Instead, they use a Bluetooth connection to send health data to your smartphone.

When a smart ring detects a person’s cardiovascular health, it uses infrared photoplethysmography technology (PPG), which uses a light source and a photodetector on the surface of the skin to measure the variations in blood circulation. These variations can estimate heart rate variability, blood oxygen saturation, blood pressure, and artery stiffness.

Out of the different sensors a smart ring has, the PPG is the most studied one due to its proposed accuracy in tracking heart rate and monitoring overall cardiovascular health. However, most studies note that they are significantly less accurate than medical-grade technology.

According to the National Library of Medicine, in a study with 35 healthy individuals, researchers compared the heart rate and heart variability measured by a smart ring with an ECG during the night. Results showed that some health parameters matched the medical-grade measurement, but most were inaccurate.

To monitor body temperature, smart rings use a sensor called a thermistor, which estimates body temperature based on a person’s skin temperature. Smart rings also use this feature to assess stress levels and identify other bodily issues. However, a systematic review of the sensors and functionalities of wearable health technology, like a smart ring, indicates that these devices may not accurately indicate a person’s core body temperature, as researchers point out that a person’s skin temperature is a few degrees Fahrenheit lower than their body’s temperature.

What’s more, researchers emphasize that a person’s skin temperature fluctuates based on environmental conditions. When considering these two factors, it may be assumed that the thermistor sensor won’t be accurate.

Companies that produce smart rings have detailed the use of a variety of sensors to support women’s health. This feature relies mostly on the smart ring’s temperature feature, which they claim to use to track menstrual cycles and fertility windows.

Numerous studies have examined the accuracy of smart rings, which have produced promising results. According to the National Library of Medicine, in a pilot study with 22 participants, researchers used a smart ring to analyze temperature changes during the menstrual cycle. They discovered that the temperature readings were consistent with oral temperatures that were taken with ambulatory equipment.

In a separate study with 26 participants, it was found that this study was consistent with the previous study’s findings, demonstrating that smart rings could be a beneficial tool for monitoring menstruation. This study also detected that there was a significant temperature drop around ovulation, highlighting that smart rings could be an additional tool to track fertility.

Although these results are promising based on limited studies on smart rings, further research is needed as they are not 100% accurate.

Most of the smart rings on the market combine various metrics such as heart rate, heart rate variability, body temperature, and movement, to estimate a person’s daily stress levels and provide tips to reduce them.

According to the National Library of Medicine, research suggests that there is a connection between stress and decreased parasympathetic regulation, the regulation that affects heart rate, heart rate variability, and respiratory rate. These are changes that a smart ring could potentially detect.

Additionally, a study with 525 college students explored this subject further. The study indicated that sleep data from smart rings could help predict stress. Notably, some experts do not consider smart rings as promising as research, as they highlight the negative effect smart rings may have on mental health. The reason is that while smart rings are promoted as a tool to shift lifestyle habits, they may cause the opposite effect, noting that constant monitoring of health metrics can create obsessive behaviors and paranoia about a person’s well-being. It could also be harmful to a person’s self-confidence, as a person may feel like they are not meeting the expectations and goals that a smart ring sets for them.

Smart rings can perform a sleep analysis by tracking a person’s heart rate, blood oxygen, and sleep cycles. They may also include features, such as a snoring score and a recovery metric that indicates energy levels before a person starts their day.

Polysomnography (PSG) is used to track sleep, which uses a variety of signals such as brain activity, eye movements, muscle activity, blood pressure, heart rate, and more. Although smart rings are not as accurate as PSG, researchers have been drawn to them due to the smart ring’s potential to monitor a person’s sleep at home comfortably.

Any current evidence on smart rings for tracking sleep is still very limited and conflicting. While some small studies highlight their potential. However, studies with bigger sample sizes indicate that smart rings can over- or underestimate some sleep parameters. A study in the National Library of Medicine compared the accuracy of several health technology devices on 35 individuals overnight. The study found that a smart ring surpassed the accuracy of smartwatches in various sleep parameters such as wake, light sleep, deep sleep, and REM sleep.

Smart rings can measure a person’s physical activity with two sensors: an accelerometer that tracks movement and speed, and a gyroscope that helps determine orientation. Smart rings gather data from these motion sensors, as well as the PPG and body temperature trackers, to understand how physical activity affects the body.

Research is limited in this area; however, a study in the National Library of Medicine focused on the accuracy of smart rings in measuring caloric expenditure and steps. The results indicated that smart rings were far from accurate, causing researchers to note the need to improve these devices, specifically their estimation of energy expenditure.

Another study on step count was consistent with a study that indicated a smart ring overestimated step count, compared to a medical-grade device to detect motion called ActiGraph.

A systematic review on wearable tech devices supported the findings of the studies, noting that they may be useful for estimating step count but shouldn’t be trusted to measure calorie expenditure.

Smart rings and other wearable devices that can track a person’s health can be useful. However, it is important not to use them to self-diagnose conditions. It is important to see a healthcare provider when experiencing any symptoms to professionally diagnose conditions.

How Much Protein Do You Really Need?

Posted on February 11, 2026 by Patrick Hercules

Protein is essential to maintaining overall good health. However, consuming extra protein often comes from eating meats high in saturated fats, which can add to elevated LDL cholesterol levels or “bad cholesterol”.

The recommended daily allowance (RDA) is 0.8 g/kg per day for adults 18 years or older. Based on weight, growing children and pregnant or lactating women require more protein than a typical adult man or woman. In terms of calories, the recommendation is that 10% to 35% of your daily calories come from protein.

You can consume your recommended daily allowance of protein from several food sources. If someone’s body weight is 70kg (154 lbs.), the RDA of protein is 56 g/day. If you drink an 8-ounce glass of milk, you’ll take in about 8 grams of protein. Add a cup of yogurt for about another 11 grams. Follow that up with a 3-ounce piece of lean/extra lean meat, which is about 21 grams of protein, and a cup of dry beans, which is about 16 grams, and you have already reached the 56-gram daily requirement for an adult man. For an adult woman, a 46-gram daily requirement of protein can be reached by eating one serving of low-fat Greek yogurt, a 4-ounce serving of lean chicken breast, and a bowl of cereal with skim milk.

The American Heart Association has a guided outline of the suggested servings for each food group:

Choose plant-based proteins such as legumes, nuts, lentils, or chickpeas. These are not only high in protein but also in fiber. Legumes, for example, can pack about 16 grams of protein per cup and are low in fat and an inexpensive alternative to meat.

Opt for low-fat or fat-free dairy options instead of full-fat dairy products.

Include regular intake of fish and seafood 2 to 3 times a week, especially oily fish such as salmon, anchovies, herring, mackerel, tuna, and sardines, which are high in polyunsaturated fats. Make sure to avoid seafood that is fried. These forms do not have health benefits.

When choosing meat or poultry, opt for lean cuts, skinless poultry, and avoid processed forms.

Eggs are another good source of protein and provide other sources of nutrients that benefit your health. Healthy individuals can include up to a whole egg or equivalent daily. However, people with dyslipidemia should be cautious about consuming eggs.

Choose main dishes that combine meat and vegetables, such as low-fat soups or stir-fry.

Be aware of portion sizes. Aim for 3-ounce servings (4 ounces raw) of cooked poultry or meat per meal.

Before you add or make any drastic changes to your diet, it is important to consult with your healthcare provider before doing so.

The registered dietitians at Jamaica Hospital Medical Center are ready to help you plan a diet that can reduce your risk of disease, maintain a healthy weight, and improve your overall health. To learn more or to schedule an appointment, please call (718) 657-7093.

High Blood Pressure and Heart Health

Posted on February 10, 2026 by Xavia Malcolm

The American Heart Association defines hypertension, or high blood pressure, as a condition that occurs when the force of your blood pushing against the walls of your blood vessels is too high.

Hypertension causes the heart to work harder, which can lead to serious cardiovascular problems, including heart failure, stroke, and heart disease. When the heart works harder, it also greatly increases the risk of a heart attack.

Managing high blood pressure and keeping it under control can significantly reduce the risk of these issues. You can reduce heart risks caused by high blood pressure by:

Monitoring your blood pressure at home
Eating a heart-healthy diet
Lowering sodium intake
Maintaining a healthy weight
Taking blood pressure medications as prescribed

Understanding the risk factors of high blood pressure is also crucial, as this can help you manage your heart health. The risk factors are:

Family history (Having a parent or close blood relative with high blood pressure increases the likelihood that you develop hypertension)
Age (As you get older, your risk for developing high blood pressure increases)
Sex (According to the American Heart Association Until age 64, men are more likely than women to get high blood pressure. At 65 and older, women are more likely to get high blood pressure)
Race (African Americans have a higher risk of developing high blood pressure compared to other races)
Obesity (Too much weight puts strain on your heart and circulatory system)
Tobacco use (Using tobacco can damage the heart and arteries, leading to elevated blood pressure levels)
Drinking too much alcohol (Drinking excessive amounts of alcohol regularly can raise blood pressure. Heavy drinking can weaken and damage blood vessels, potentially leading to hypertension)
Lack of physical activity (Regular exercise strengthens the heart; when you are inactive, the heart must work harder to circulate blood, and harder pumping leads to high blood pressure)
Eating an unhealthy diet (Eating a diet that is high in sodium, trans fats, saturated fats, and sugar increases your risk)

One of the dangers of living with high blood pressure is that many people are unaware that they have it. This is why hypertension is called “The Silent Killer.” Living with untreated high blood pressure can cause significant damage to the cardiovascular system over time.

Early detection and treatment of high blood pressure can delay or prevent complications that affect cardiovascular health. Treatment may involve medications and lifestyle modifications.

Jamaica Hospital Medical Center’s cardiology department features a specialized Hypertension Center that offers high-quality, patient-centered care for hypertension and incorporates the latest treatment advances. This center was established specifically to assist patients who do not respond effectively to traditional hypertension medications.

The American Heart Association has recognized our Hypertension Practice Center for meeting or exceeding its standards for hypertension treatment. To schedule an appointment with our Cardiology Department, please call 718) 206-7100

First Patient Treated at Jamaica Hospital Medical Center with New, Minimally Invasive Technology to Help Control High Blood Pressure

Posted on February 9, 2026 by Jamaica Hospital Medical Center

February 2026 – Jamaica Hospital Medical Center is pleased to announce that it is the first hospital in Queens to offer a new renal denervation (RDN) procedure to treat certain patients with high blood pressure. The hospital’s cardiology team recently and successfully completed its first case.

Approved by the U.S. Food and Drug Administration (FDA) in November 2023, the Symplicity Spyral™ renal denervation (RDN) system involves a minimally invasive procedure that targets nerves near the kidneys that can become overactive, causing high blood pressure. The procedure – also known as the Symplicity™ blood pressure procedure – is approved for use as an adjunctive treatment in patients with high blood pressure (or hypertension) when lifestyle changes and antihypertensive medications do not adequately control blood pressure.

Hypertension is the single largest contributor to death, and affects about 50% of U.S. adults. Of the U.S. adults who are aware of their hypertension, about 80% do not have it under control.

The Symplicity blood pressure procedure is clinically proven to help reduce high blood pressure, which can lower serious health risks. After mild sedation, the doctor inserts a very thin tube into the artery leading to the kidney. The doctor then administers energy to calm the excessive activity of the nerves connected to the kidney. The tube is removed, leaving no implant behind.

High blood pressure is a significant issue for patients worldwide. For people with hypertension, medication and/or lifestyle changes can help reduce blood pressure, but studies have shown that many people still don’t have control over their condition. The Symplicity blood pressure procedure can provide patients with a blood pressure reduction benefit that is ‘always on’ and doesn’t require a permanent implant – it can also help patients regain their peace of mind. We are pleased to have treated our first patient with this new technology, and we look forward to the future of hypertension care by offering innovative solutions to the people of Jamaica, Queens.

Jamaica Hospital’s Hypertension Center provides the highest quality, patient-centered hypertension care. The Hypertension Center was created to treat patients who do not respond well to traditional hypertension medication treatments. The American Heart Association has recognized our Hypertension Practice Center as meeting or exceeding standards for hypertension treatment.

If you or someone you know is experiencing high blood pressure or difficulty controlling it, talk to your doctor to see if the Symplicity blood pressure procedure is a possible treatment option: visit this link to learn more.

Meet Our Doctors- Dr. Melvin Mathai

Posted on February 6, 2026 by Patrick Hercules

We are pleased to introduce Dr. Melvin Mathai, the newest member of our pediatrics team at Jamaica Hospital Medical Center.

Dr. Mathai attended Hofstra University for his undergraduate degree and The New York Institute of Technology College of Osteopathic Medicine (NYITCOM) for his medical degree. He completed his residency at Maimonides Medical Center in Brooklyn, New York. Dr. Mathai is board-eligible and holds certifications in ACLS, PALS, and NRP.

Dr. Mathai was drawn to a career in medicine because it combines science, problem-solving, and making a meaningful difference in people’s lives, as well as the ability to build long-term relationships with his patients while positively impacting their health and well-being. He chose pediatrics as his specialty because it felt like a natural fit for him, and he enjoys working with children and families. “I wanted to be a part of a child’s growth and development over time. I love the energy, honesty, and resilience of children, and I find it incredibly rewarding to help guide parents through each stage of their child’s life, from newborn care to adolescence.” Dr. Mathai believes that pediatrics allows him to focus on prevention, education, and building trust with families. “I hope to provide compassionate, thoughtful, and accessible care while creating a welcoming environment where families feel heard and supported”, he said.

As a pediatrician, Dr. Mathai provides comprehensive outpatient pediatric care, which includes well-childcare visits, newborn care, vaccinations, developmental and behavioral concerns, and adolescent health. He also evaluates and manages common child illnesses, which include asthma, allergies, eczema, infections, minor injuries, anxiety, and school-related issues.

Born and raised in Queens, Dr. Mathai is proud to serve as a pediatrician in such a close-knit, family-oriented community like Howard Beach because it is the community in which he grew up. He returned home to provide compassionate, culturally informed care to the families who shaped him. “I’ve always loved the diversity, energy, and incredible food that make this area so special, and I’m grateful for the opportunity to give back to the community,” he said.

Dr. Mathai is a proud Gold Humanism Award recipient, a massive Knicks fan (yes, he still believes every year is their year), and an anime geek at heart. When he’s not in the office, he is usually chasing after his two little kids, who keep him laughing—and humbled—daily.

His goal as a pediatrician is simple: “Partner with parents, answer questions honestly, and help families feel confident about their child’s health. I strive to practice evidence-based and personable medicine while treating every child as if they were my own,” he said. He wants to make families feel supported, make kids feel safe, and bring high-quality, down-to-earth care to every visit. “I hope to help build a healthier, happier community, one tiny sneaker at a time,” he said.

Age-Related Macular Degeneration Awareness Month

Posted on February 5, 2026 by Patrick Hercules

Age-related macular degeneration (AMD) is an eye disease that can blur your central vision. It occurs when aging damages the part of the eye that controls sharp, straight-ahead vision, called the macula. The macula is part of the retina, the light-sensitive tissue at the back of the eye.

Age-related macular degeneration is a common condition and the most common cause of severe loss of eyesight among people 50 and older. It is important to note that people rarely go blind from it. However, losing your central vision makes it harder to see faces, read, drive, or do close-up work like cooking or fixing things around the house.

There are two types of age-related macular degeneration: dry and wet. Most people with age-related macular degeneration have dry AMD, also called atrophic AMD. This is when the macular gets thinner with age. Dry AMD happens in three stages:

Early

Intermediate

Late

Wet AMD, also called advanced neovascular AMD, is a less common type of late AMD that causes faster vision loss. Dry AMD can turn into wet AMD at any stage; however, wet AMD always occurs in the late stage.

The most common symptoms of age-related macular degeneration can include:

Blurry or fuzzy vision

Difficulty recognizing familiar faces

Seeing straight lines appearing wavy

A dark, empty area or blind spot appears in the center of a person’s vision

The presence of tiny yellow deposits in the retina called drusen is one of the most common early signs of age-related macular degeneration. It can mean the eye is at risk of developing more severe age-related macular degeneration.

Several risk factors that can contribute to developing age-related macular degeneration include:

Eating a diet high in saturated fat

Smoking

High blood pressure or hypertension

To diagnose age-related macular degeneration, an eye doctor will look at your medical history and perform an eye exam. They may also perform other tests to help diagnose AMD, including:

A visual acuity test

Pupil dilation

Fluorescein angiography

Amsler grid

Specific treatment for age-related macular degeneration is determined by your eye doctor based on:

Your age, overall health, and medical history

The extent and nature of the disease

Your tolerance for specific medications, procedures, or low-vision therapies

The expectations for the course of the disease

Your opinion or preference

There is no current treatment for dry AMD; however, vision rehabilitation programs and low-vision devices can be used to build visual skills, develop new ways to perform daily living activities, and adjust to living with age-related macular degeneration.

The main treatment for wet AMD is an injection of medications called anti-VEGF agents. VEGF stands for vascular endothelial growth factor.

There is no cure for age-related macular degeneration. However, research shows that you may be able to lower your risk of AMD, or slow vision loss from AMD by:

Quitting smoking

Getting regular exercise

Maintaining healthy blood pressure and cholesterol levels

Eating healthy foods that include leafy green vegetables and fish

AMD happens very slowly in some people and faster in others. If you have early AMD, you may not notice vision loss for a long time. It is important to get regular eye exams to find out if you have AMD.

If you’re experiencing symptoms of dry or wet AMD, you can schedule an appointment at Jamaica Hospital Medical Center’s Ophthalmology Center by calling (718) 206-5900.

How Does Negative News Affect Your Mental Health?

Posted on February 4, 2026 by Patrick Hercules

Current events in the news have been very tense, stressful, and depressing. The constant barrage of negative news on local and cable news stations, as well as social media, feels never-ending.

Watching or reading the news can have a negative impact on our mental health.

When we watch news footage that upsets us, our body’s “fight or flight” response is activated. Adrenaline and the stress hormone cortisol are released, causing us to experience symptoms similar to those we feel when we are in danger, such as a rapid heart rate, shallow breathing, and an upset stomach, among others.

Negative news can increase symptoms of depression and anxiety. According to Mental Health America (MHA), one study found that people showed an increase in symptoms after only 14 minutes of news consumption. The symptoms worsen when people feel they have no ability to improve the situations they are learning about on the news.

As these symptoms worsen, they can cause a person to doomscroll. Doomscrolling is when a person actively seeks saddening or negative material to read or scroll through on social media or news media outlets. Doomscrolling can also greatly impact your mental health as it reinforces negative thoughts and a negative mindset, and can also cause feelings of:

Apprehension

Sadness and anger

Uncertainty about the future

Doomscrolling has many potential effects, including:

May worsen mental health issues

May lead to insomnia

Doomscrolling can be attributed to someone relying on social media for their news, which can drive addictive behavior. In 2020, the Pew Research Center found that about 53% of U.S. adults said they “often” or “sometimes” get their news from social media. Among the social media sites where they get their news from, 36% of Americans regularly get their news from Facebook, 23% from YouTube, and 15% from Twitter/X.

Regularly getting your news can be detrimental as clickbait headlines, mis- and disinformation, and social media algorithms are designed to keep you coming back for more, making it difficult to stop returning to apps for your news.

People are more likely to be negatively affected by the news when it is personally relevant to them and when they share an identity with the people involved in the news story. This is the case for members of the BIPOC and LGBTQIA+ communities because they are more often targets of violence and hate crimes.

With all the negative news, there are many ways to support ourselves and each other during these times, such as:

Identifying your triggers by taking time to think about the topics that cause symptoms of anxiety and depression, so you can limit your consumption of media with triggering content

Reading the news instead of watching news videos. Studies done by the American Psychological Association (APA) show that this can be less triggering due to written news articles containing less disturbing imagery

Limiting your time watching or reading the news. Although doomscrolling may help you feel more informed, it ultimately does more harm than good. Aim for no more than 30 minutes a day if possible

Engaging in an enjoyable activity after taking in the news to help you decompress

Getting involved with a group that is working on the issues you are passionate about can help you feel empowered to make a change instead of feeling helpless about the world around you

Joining a supportive community of people who share a common identity, such as an affinity group, can help foster resilience and create solidarity during these difficult times of prejudice or injustice

Being conscious of where your news sources come from, as some can be more based on opinions than facts. Make sure the information you’re getting is accurate and provides diverse perspectives

Focusing more on what brings you joy and happiness, such as engaging in social activities, spiritual practices, physical movement, mindfulness and gratitude practices, creative hobbies, journaling, or spending time with a pet

Today’s 24-hour news cycle can seem difficult to stay clear of. If you need the assistance and support of a mental health professional at Jamaica Hospital Medical Center, please call 718-206-5575 to schedule an appointment.

How Does Winter Weather Increase Your Risk of Cardiovascular Disease?

Posted on February 1, 2026 by Patrick Hercules

As we get deeper into this winter season, extreme, record-low cold temperatures have brought snow and frigid winds with them. These conditions can severely affect your heart, especially if you already suffer from or are at risk of cardiovascular disease.

The cold temperatures affect the heart by causing blood vessels to constrict, which is the body’s natural reaction to send blood deeper into the body. This doesn’t cause problems for those with healthy arteries. However, if someone has arteries that were narrowed by fatty plaque, cold-related blood vessel constriction can leave them more vulnerable to chest pain or a heart attack. This is especially true when engaging in a strenuous outdoor activity such as walking quickly in a strong wind or shoveling snow, which can commonly trigger a heart attack.

Strenuous outdoor activity in cold weather isn’t the only thing that can put the heart at risk. Cold temperatures also increase the risk of suffering from hypothermia. Hypothermia means the body’s temperature has fallen below 95 degrees Fahrenheit or 35 degrees Celsius, and the body can’t produce enough energy to keep its temperature warm enough. Cold-related blood vessel constriction keeps vital organs warm and helps reduce heat loss. If a person has narrowed blood vessels, the heart must work harder to pump blood through the body, which then raises blood pressure and puts stress on the heart. Hypothermia has several symptoms, including:

Lack of coordination

Slowed reaction time

Mental confusion

Shivering

Sleepiness

Hypothermia can be life-threatening, so it is extremely important to take proper precautions to stay warm by dressing in layers, keeping your head and ears covered, and keeping your hands and feet warm.

If you are going to engage in any strenuous outdoor activities, here are some tips to keep you safe:

Take frequent breaks

Learn the warning signs of a heart attack and listen to your body

Learn CPR

Be aware of the dangers of hypothermia

Don’t drink alcohol before or immediately after a strenuous activity

Consult with your healthcare provider

If you have, or are at risk of developing, or are experiencing symptoms of a heart condition, you should consult a cardiologist to explore the most effective precautions you can take to protect your heart health during the winter season. You can schedule an appointment at Jamaica Hospital Medical Center’s Cardiology Department by calling (718) 206-7100. If you are experiencing an emergency, please dial 911 right away.

Cold, Flu, or Pneumonia?

Posted on January 30, 2026 by Patrick Hercules

The winter season can be difficult to navigate when there is the risk of developing one of three respiratory illnesses, such as the common cold, flu, or pneumonia. All three of these illnesses share similar symptoms but are all different and range from mild to severe.

The common cold is the least serious of the three respiratory illnesses, as it presents milder symptoms. Common cold symptoms include:

Mild cough

Sore throat

Runny nose

Congestion

When a person is suffering from the common cold, they will usually feel run-down for a couple of days and are able to treat their symptoms with over-the-counter remedies such as cough syrup and cold medications.

Unlike a cold, the flu or influenza hits hard and fast, with more intense symptoms usually beginning more suddenly than a cold. Symptoms of the flu include:

A high, sudden fever

A stuffy nose

A dry cough

Headaches

Muscle aches

Extreme fatigue

Chills and sweats

Lack of appetite

A flu vaccine is available to help prevent an infection from the flu virus, as well as medications that can help reduce the severity of symptoms.

Pneumonia is typically caused by a bacterial or viral infection, with the illness and its symptoms being more severe than the cold or flu. Symptoms of pneumonia include:

Chest pains that increase when you cough

Coughing up blood or mucus

High fever

Difficulty breathing

Inability to breathe deeply

Chills

Extreme and weakening fatigue

Lack of appetite

Clammy skin and frequent sweating

Bacterial and viral pneumonia are treatable with antibiotics and antivirals, respectively. Pneumonia can be very serious and even life-threatening for the elderly, very young children, and those with chronic lung conditions. Vaccines for pneumonia are available for high-risk patients.

Preventing respiratory illnesses such as the common cold, flu, or pneumonia requires taking proactive steps to reduce the risk of developing and/or spreading these infections, including:

Washing your hands regularly

Avoiding contact with individuals who are sick with any of these respiratory illnesses

Getting your annual flu vaccination

Getting vaccinated with the pneumococcal and Hib vaccines if you are in an at-risk group

If you are experiencing any symptoms of a cold, flu, or pneumonia, you can schedule an appointment with a physician at Jamaica Hospital Medical Center’s Ambulatory Care Center. Please call (718) 206-7001.
