Triggers for Rheumatoid Arthritis Flares

From everydayhealth.com

People with rheumatoid arthritis (RA) often cycle between times when their symptoms are relatively well controlled and when pain, stiffness, swelling, and fatigue suddenly worsen. These episodes, known as flares, can last for days or weeks and may interfere with daily life.

While flares can seemingly come out of nowhere, certain factors may increase the likelihood of symptoms worsening. Identifying your personal triggers may help you avoid them, or at least reduce their frequency, severity, or duration.

Common Triggers to Look Out For

The exact cause of an RA flare isn't always clear. Over time, many people with RA notice that certain circumstances tend to precede a flare. Although triggers differ from one person to the next, experts have identified many common culprits.

Environmental Triggers

“One of the most common questions I get from patients with rheumatoid arthritis is whether certain environmental factors can trigger their symptoms,” says Priyanka Dongare, MD, a fellow in Stony Brook Medicine’s Division of Rheumatology in New York. “While environmental triggers don’t cause RA flares in every patient, many people notice patterns.” These triggers include:

• Weather Changes “Cold weather and sudden weather changes are probably the most frequently reported triggers,” says Dr. Dongare. But the weather may not have as much of an impact as patients may think. A meta-analysis found only that weather’s impact on RA symptoms appears to be minimal.
• Air Pollution Higher levels of air pollution have been linked to an increased risk of RA flares. One study found that exposure to pollutants including PM2.5, PM10, nitrogen dioxide, and ozone was associated with greater disease activity and higher levels of inflammation.
• Occupational Exposures Dust, fumes, and chemical irritants may aggravate symptoms in some people with RA. But most research has examined these exposures as risk factors for developing RA rather than triggers for flares.
• Cigarette Smoke and Secondhand Smoke Tobacco smoke causes whole-body inflammation, one of the main triggers for arthritis. “Multiple studies have demonstrated that smoking not only increases the risk of developing RA, particularly seropositive RA, but can also worsen disease activity and reduce response to treatment,” says Dr. Dongare. 

Physiological Triggers

Changes in the body, some of which you can manage through lifestyle modifications, can affect inflammation and increase your risk of a flare.

• Sleep Deprivation “Poor sleep is one of the most common triggers I see in clinical practice,” says Dr. Dongare. Research has shown that inadequate or disrupted sleep can increase inflammatory cytokines such as IL-6 and TNF-alpha, which are key drivers of RA inflammation. “Patients often say that after several nights of poor sleep, they experience increased pain, stiffness, and fatigue.”
• Physical Overexertion There’s a fine line between exercise and overdoing it. While regular movement is recommended for people with RA, pushing your body too hard can temporarily increase joint pain, stiffness, and fatigue. Repetitive motions, heavy lifting, or unusually strenuous activity may aggravate already sensitive joints, making flare symptoms feel worse.
•

• Hormonal Shifts Hormones help regulate immune function. Sharp drops in oestrogen, such as after childbirth, around menstruation, and during menopause, may increase disease activity and trigger flares.

• Inconsistent Medication Skipping doses, delaying refills, or stopping medication because you think you feel fine can increase the risk of a flare. Disease-modifying antirheumatic drugs (DMARDs) and biologics help keep the immune system's inflammatory activity under control, and can worsen symptoms if not taken as prescribed.
• Added Sugars and Ultra-Processed Foods Diets that include these foods may promote inflammation and worsen RA symptoms over time. These foods have been linked to immune dysregulation and increased inflammatory signalling, which may contribute to greater disease activity.

Emotional Triggers

The state of your mental health can also affect your RA symptoms. 

• Stress “While stress doesn't directly cause RA, it can amplify inflammation and make symptoms feel significantly worse,” says Dongare. One long-term study found that those with greater perceived stress had worse pain, greater fatigue, and lower physical function.
• Grief Research suggests that intense grief is associated with higher levels of inflammation, and experts note that the emotional strain of losing a loved one may increase disease activity and flares.
• Anxiety A systematic review found that about 1 in 5 people with RA experience clinically significant anxiety symptoms. Research has linked anxiety to greater pain, fatigue, and disease burden.
• Depression Depression and RA have a bidirectional relationship. One review found depression is associated with higher disease activity and worse treatment outcomes in inflammatory arthritis, suggesting that depressive symptoms can make flares more difficult to manage.

Track Your Triggers

Because RA affects everyone differently, tracking your triggers and symptoms can help you identify patterns that may otherwise go unnoticed. Dongare suggests keeping a symptom diary or using a smartphone app to track these variables:

• Pain levels
• Stiffness
• Fatigue
• Sleep quality
• Stress
• Diet
• Exercise
• Environmental concerns

“Tracking can also help rheumatologists distinguish between inflammatory disease activity and other contributors to pain such as osteoarthritis, fibromyalgia, sleep disorders, or mood disorders,” says Dongare.

Tracking is a tool, not a diagnosis. She cautions against assuming that every flare has a clear cause, since RA symptoms can naturally fluctuate. If you consistently notice the same pattern, though, you should discuss it with your rheumatologist.

How to Avoid Your Trigger(s)

While you can't prevent every RA flare, addressing common triggers may help reduce their frequency and severity. The key, says Dongare, is to focus on factors you can control.

• Prioritize sleep. Poor sleep can worsen inflammation, pain, and fatigue, so maintaining good sleep habits may help keep symptoms in check. 
• Manage stress. "Stress management should be part of every patient’s treatment plan,” says Dongare. Meditation, counselling, exercise, and strong social support systems can help reduce the physical toll of chronic stress.
• Stay physically active. “Many patients worry that exercise will worsen their arthritis, but the evidence consistently shows the opposite,” she says.
• Follow a healthy eating pattern. Dongare says maintaining a healthy weight and following a Mediterranean-style diet may support overall health and help reduce systemic inflammation.
• Quit smoking. It’s not good for any part of your body — joints or otherwise.
• Take medications as prescribed. Skipping doses or stopping treatment can increase the risk of disease activity and flares.

“Avoiding triggers can help manage symptoms, but controlling the underlying inflammation with appropriate medical treatment remains the foundation of RA care,” she says. Keep up with regular rheumatology appointments and talk with your healthcare provider before making changes to your treatment plan.

Questions to Ask Your Doctor

If you notice possible RA flare triggers, share them with your healthcare professional. They can interpret symptoms, adjust treatment if needed, and keep your disease under control.

• What symptoms or patterns should I track to better identify my RA flares?
• Could my current medications or dosing schedule be adjusted to better prevent flares?
• Are there environmental or lifestyle triggers I should be most cautious about?
• How can I safely modify my diet, activity level, or daily routine without making my symptoms worse?
• Should I adjust or pre-plan treatment around known triggers like stress, illness, or travel?
• When should I contact you if I think I’m having a flare?

The Takeaway

• RA flares are periods of worsening pain, stiffness, swelling, and fatigue. While they can seem unpredictable, research suggests they’re often linked to environmental, physical, and emotional triggers that vary by person.
• Common triggers include weather changes, air pollution, smoking, workplace irritants, poor sleep, overexertion, hormonal shifts, missed medications, diet, and stress-related factors like anxiety or grief.
• Because triggers differ widely, tracking symptoms alongside daily habits can help identify personal patterns. Working with a healthcare provider can help confirm flare patterns and guide more effective treatment.

4 surprising arthritis triggers hiding in toothpaste

From rollingout.com

Common oral care products may trigger inflammatory responses in susceptible individuals

The morning ritual of brushing teeth seems harmless enough, but emerging connections between certain toothpaste ingredients and autoimmune conditions have raised important health questions. While maintaining oral hygiene remains crucial, understanding potential risks helps consumers make informed choices about their dental care products.

The relationship between oral health and systemic inflammation has gained attention as scientists explore how everyday products might influence immune system function. Certain compounds commonly found in toothpaste may contribute to inflammatory responses that could potentially trigger or worsen autoimmune conditions like rheumatoid arthritis in susceptible individuals.

Antimicrobial agents disrupt immune balance

1. Triclosan, a widely used antimicrobial agent, appears in numerous toothpaste formulations designed to combat bacteria and prevent gum disease. While effective at killing harmful microorganisms, this compound may also disrupt the delicate balance of beneficial bacteria in the mouth and throughout the body.

The human microbiome plays a crucial role in immune system regulation. When antimicrobial agents eliminate both harmful and beneficial bacteria indiscriminately, the resulting imbalance can trigger inflammatory responses that may contribute to autoimmune dysfunction.

Triclosan has been detected in blood samples and urine, indicating that it absorbs through oral tissues during routine brushing. This systemic exposure means the compound can potentially influence immune function throughout the body, not just within the mouth.

The chemical structure of triclosan allows it to persist in body tissues, potentially causing cumulative effects over time. Regular exposure through daily toothpaste use may create chronic low-level inflammation that contributes to autoimmune disease development in genetically predisposed individuals.

Fluoride compounds trigger inflammatory pathways

2. Fluoride preparations in toothpaste, while beneficial for preventing tooth decay, may inadvertently stimulate inflammatory responses in some people. Different fluoride compounds used in oral care products can interact with immune system cells in ways that promote inflammation.

Sodium fluoride, the most common form found in toothpaste, can accumulate in joint tissues over time. This buildup may contribute to the inflammatory processes characteristic of rheumatoid arthritis, particularly in individuals with genetic susceptibilities to autoimmune conditions.

The mechanism involves fluoride’s ability to interfere with enzyme systems that regulate inflammatory responses. When these regulatory systems become disrupted, the immune system may begin attacking healthy joint tissues, leading to the chronic inflammation seen in rheumatoid arthritis.

Excessive fluoride exposure has been linked to skeletal fluorosis, a condition that shares some similarities with rheumatoid arthritis symptoms, including joint pain and stiffness. This overlap suggests potential pathways through which fluoride might contribute to autoimmune joint problems.

Surfactants alter immune cell function

3. Sodium lauryl sulfate (SLS), the foaming agent that creates toothpaste’s characteristic lather, may influence immune system behaviour through its interaction with cellular membranes. This detergent-like compound can penetrate oral tissues and potentially reach systemic circulation.

SLS has demonstrated the ability to alter cell membrane permeability, which could affect how immune cells communicate and respond to threats. Disrupted cellular communication may contribute to the immune system confusion that characterizes autoimmune diseases.

The compound’s harsh cleansing action may also damage the protective barriers of oral tissues, creating opportunities for bacteria and other inflammatory triggers to enter the bloodstream. This increased bacterial translocation could stimulate chronic immune responses that contribute to autoimmune disease development.

Regular exposure to SLS through daily brushing may create ongoing irritation and inflammation in oral tissues. This chronic inflammatory state could serve as a persistent trigger for systemic autoimmune responses in susceptible individuals.

Artificial preservatives activate immune responses

4. Chemical preservatives used to extend toothpaste shelf life may inadvertently trigger immune system activation. Compounds like parabens, formaldehyde-releasing agents, and other synthetic preservatives can act as immune system irritants.

These preservatives may function as haptens – small molecules that become antigenic when they bind to proteins in the body. Once this binding occurs, the immune system may begin producing antibodies against the preservative-protein complexes, potentially leading to autoimmune reactions.

The cumulative effect of daily exposure to multiple preservatives through oral care products may overwhelm the body’s natural detoxification systems. This toxic burden could contribute to the chronic inflammation that underlies autoimmune conditions like rheumatoid arthritis.

The oral-systemic connection

The mouth serves as a gateway between the external environment and internal body systems. Ingredients absorbed through oral tissues can quickly enter systemic circulation, influencing immune function throughout the body.

Gum disease and oral inflammation have already been linked to increased rheumatoid arthritis risk, suggesting that the oral environment plays a significant role in autoimmune disease development. Adding potentially inflammatory toothpaste ingredients to an already compromised oral environment may amplify these risks.

Making safer choices for oral care

Natural alternatives to conventional toothpaste formulations may reduce exposure to potentially problematic ingredients. Products free from triclosan, SLS, artificial preservatives, and excess fluoride offer options for those concerned about autoimmune disease risks.

Simple ingredients like baking soda, sea salt, and essential oils can provide effective cleaning action without the inflammatory potential of synthetic compounds. However, consulting with dental professionals ensures that alternative oral care approaches maintain adequate protection against tooth decay and gum disease.

Understanding these connections empowers consumers to make informed decisions about their oral care products while maintaining the dental hygiene necessary for overall health.

Common Triggers for Psoriatic Arthritis

From healthcentral.com

From weather to medication interactions, learn all the ways this condition can be triggered 

Psoriatic arthritis (PsA), an autoimmune disease that leads to joint pain and skin rashes, can be unpredictable and change over time. If you have PsA, you know how hard it can be to pinpoint what’s causing your symptoms to worsen. There are multiple internal and external factors that impact the immune system, and figuring out which ones might set off a flare with psoriatic arthritis isn’t easy. What’s more, these factors, known as triggers, can vary from person to person. We asked the experts about some of the common psoriatic arthritis triggers and how to shield yourself from worsening symptoms.

Stress

“Stress is one of the biggest triggers for flares,” says Waseem Mir, M.D., a rheumatologist at Northwell Lenox Hill Hospital in New York City. Stress often occurs after an unpleasant life circumstance, new demands, an event like a death in the family. Stress could also result from an overall ongoing and challenging life experience such as poverty or marital dissatisfaction.

Short-term stress can help you respond to life’s challenges, but if the stress-inducing event goes on and on, your reaction can become more long-term, also known as chronic stress. According to an article in Frontiers in Human Neuroscience, large bodies of evidence show that chronic stress can activate inflammation in the brain and the body.

The relationship between stress and inflammation becomes clear with psoriatic disease. In one study, patients with psoriasis in 31% to 88% of cases reported stress as a trigger for their psoriasis and a higher incidence of psoriasis occurred in those with a stressful event in the previous 12 months.

Illness

A variety of infections have been reported as triggers of psoriatic disease. According to a 2024 review, both bacterial and viral infections have been responsible for the onset or recurrence of psoriatic disease. Bacterial infections include Streptococci pyogenes (strep throat), Staphylococcus aureus (staph infection), Porphyromonas gingivalis (periodontal disease). Viral infections related to psoriatic disease include human immunodeficiency virus (HIV), hepatitis C virus, and COVID-19.

Lack of Sleep

“Lack of sleep may contribute to psoriatic arthritis flares, but we need more research in this area,” says Melanie H. Smith, M.D., Ph.D., a rheumatologist at Hospital for Special Surgery in New York City, adding that the cause and effect may not be a straightforward relationship. “With sleep, maybe it’s not necessarily about being a trigger for psoriatic arthritis, but when we get less sleep, we feel more pain.” Given that people with psoriatic arthritis are more likely to have trouble sleeping, often from symptoms of the condition, exacerbation of pain is a real problem. According to the Arthritis Foundation, all the more reason to keep your psoriatic arthritis symptoms in check through proactive treatment.

Skin Trauma

If you have psoriasis along with your psoriatic arthritis, skin trauma or injury can be a flare of your symptoms, known as the Koebner phenomenon. According to the National Psoriasis Foundation, psoriasis can appear in the areas of the skin that have been harmed as a result of scratches, sunburns, bug bites, and vaccinations. The exact reason this occurs remains unclear without enough evidence to support any one theory.

Medication Disruptions

“Another trigger can be changing or discontinuing medication,” says Dr. Smith. That’s because a different mechanism of action might not work as well—or not work at all if you suddenly stop taking your medication. All of this can lead to worse symptoms, she explains. And in the world of psoriatic disease, medication changes happen quite frequently, according to the National Psoriasis Foundation.

Dr. Smith says that sometimes you will need to take the lead in shortening the time you are without treatment. “Sometimes it’s about making sure the doctor’s prior authorization is not running out anytime soon or if it is, letting the doctor know,” she explains. “I’m never upset about a patient advocating for themselves.”

Changing Physiology 

There are other times related to your medication where you could experience a psoriatic arthritis flare, but it may not be the fault of your medication. “Sometimes people will blame their medications for flares, reporting that their medications have stopped working,” Dr. Mir says. Usually, though, it is more complicated than that. “Sometimes it is about your body becoming weaker when you have a flare, not the medication stopping working,” he says. “Our physiology changes over time—especially as we grow older.”

“Maybe the medication was working for you five years ago, but now you are five years older and your body has changed,” Dr. Mir adds. These changes in your body as you age can sometimes trigger a PsA flare.

Alcohol and Cigarettes

A complex relationship has been discovered between psoriatic disease and alcohol. People living with psoriasis tend to consume more alcohol than the general population, according to the National Psoriasis Foundation. Whether that’s because the discomfort of the disease drives people to self-medicate, if the goal of drinking is to help treat the symptoms of the disease, the opposite is true. Drinking alcohol can cause dehydration and nutritional issues, and also create oxidative stress and inflammation.

Smoking should also be avoided if you have psoriatic arthritis. Smoking is an independent risk factor for psoriatic disease. Why? One of the reasons is that nicotine stimulates immune cells by releasing inflammatory cytokines, according to a 2024 article in Cell Communication and Signaling. And if you are already genetically predisposed to psoriatic disease, it seems that smoking can turn up the volume. Smoking upregulates the expression of psoriasis-associated genes.

Diet

Because everyone reacts differently to food, there is no one recommended diet for people with psoriatic arthritis, but Dr. Smith says that following a nutritious meal plan can help shield people from psoriatic arthritis symptom triggers.

In particular, foods with anti-inflammatory properties may help ease PsA symptoms: There is some evidence to support eating a Mediterranean diet if you have psoriatic disease. This diet emphasis is on plant-based foods, fruits, vegetables, whole grains, beans and legumes, fatty fish and olive oil.

A healthy diet is not just about what you eat, but also about what you leave off your plate, explains Dr. Smith. Because processed food may cause psoriatic arthritis symptoms to flare, limiting consumption of it can be helpful for keeping the disease in check.

Weight Gain

On average, people with PsA have a higher mean body mass index (BMI) than those with psoriasis, rheumatoid arthritis, or the general population, according to a study in Rheumatology; up to 45% of people with psoriatic arthritis are obese. Adipose (fat) tissue can act as an active organ in our bodies, secreting proinflammatory cytokines. As a result, obesity has the potential to activate many of the known immune-inflammatory pathways, causing a flare in symptoms to occur.

Additionally, carrying weight may also prevent your treatment from working as well as it should. According to the Arthritis Foundation, a number of studies have shown that for people with psoriatic arthritis, being obese raises the chances of not improving with certain types of medications.

Cold and Dry Weather

Dr. Mir said that weather changes can be a trigger for PsA symptoms. “I just spoke to a patient who was flaring with foot and hand pain and it seemed possible that it was from a weather change,” he says.

Dr. Smith agrees that weather changes seem to frequently be reported as a trigger of psoriatic arthritis symptoms. “Some patients say that their skin and joints get worse,” she says. The research supports the impact of weather exposure and variations. For example, a 2022 study reported that patients with psoriasis who had occupations with more sunlight exposure were less likely to report aggravation of psoriasis in autumn/winter. On the other hand, smoking and hyperlipidaemia (elevated lipids) were positively associated with the seasonal aggravation of symptoms.

Shielding Yourself From Potential Triggers

While you probably won’t be able to avoid all the potential psoriatic arthritis triggers, there are ways to reduce their impact. “Exercise does seem to help shield people from some of the triggers,” says Dr. Smith.

Keeping on top of your treatment can also impact the power of the triggers. “If your medication is barely covering your disease and you get an extra blow to the system, you are going to feel it,” says Dr. Mir. “On the other hand, if your treatment is covering your condition really well, then if you have a small hit from a trigger, the medication may cover it.”

Understanding Rheumatoid Arthritis Triggers

From healthcentral.com 

Discover what’s making your RA symptoms reappear, how to spot a flare in the making, and what to do about it

Rheumatoid arthritis (RA) is an unpredictable condition, but one thing you can predict is that at some point, your joint pain will flare up. Why this happens varies. “Frequently, we don’t know why someone has a flare of their disease,” says Jason Liebowitz, M.D., an assistant professor of medicine in the division of rheumatology at Columbia University Vagelos College of Physicians and Surgeons in New York City. Other times the cause is clearer. Here are some of the most likely triggers, ways to spot a flare in the making, and how to nip it in the bud.

An Infection

In RA, a hyperactive immune system mistakenly attacks the joints. When you come down with a cold or the flu, your immune system naturally goes into overdrive to attack the germs that caused it. Sometimes your joints become casualties of that attack. Your meds factor into flares, too. “Part of the issue is that often when people have an infection, we have them stop their rheumatoid arthritis medicines, especially if the medicines are suppressing their immune system,” says Amish Dave, M.D., a board-certified rheumatologist at Virginia Mason Franciscan Health in Seattle, WA. “People are more likely to flare when they’re off their medications.”

A Change in Your Meds

Speaking of going off your meds, talk with your doctor before making any changes to your treatment due to changes in insurance coverage or side effects. While some people can stop taking their RA drug with barely a symptom, others will flare right away. Because it’s hard to know which category you fall into, don’t make medication changes on your own. Your doctor will help you find the RA medicine that manages your symptoms with the fewest side effects, and that is covered by your insurance.

The Weather

If your joints ache more on cold or humid days, you’re not imagining it. “Anecdotally, you’ll hear many people talk about certain times of the year, in terms of weather or changes in temperature, where they’ll notice that their symptoms are more active,” says Dr. Liebowitz. A study in Pain Research and Management found that people with RA had more tender joints in periods of extreme high and low temperatures and humidity during the summer and winter months. Weather changes might trigger joint pain by making tissues swell or thickening the synovial fluid that normally lubricates joints, says the Arthritis Foundation.

Stress

The connection between stress and RA goes two ways. When you’re stressed, your body’s fight-or-flight response kicks into gear, causing your immune system to release inflammatory chemicals that make your joints swell up and hurt, says the Arthritis Foundation. And when your joints become so inflamed that you can’t do all the things you want to do, it can stress you out even more. Gaining control over your RA with medication and finding ways to relieve stress can help you break this cycle. Some relaxation methods, like yoga, taking a warm bath, or going on walks are good for both your mind and joints.

Hormone Changes

Women are two to three times more likely to get RA than men, says the U.S. Centers for Disease Control and Prevention (CDC). Hormones are likely behind the gender difference, and might play a role in disease severity, too. As evidence, women with arthritis report more pain when their oestrogen levels are low. Those who take hormones with their RA medications are more likely to achieve remission, according to a study in Rheumatology (Oxford). 

What’s more, many women say symptoms lessen, or even disappear, during pregnancy when hormone levels shift —only to flare up within the first three months after they deliver.

Diet

Do certain foods trigger flares? It’s the number one question Dr. Liebowitz’s patients ask. There could be a link between certain foods and RA symptoms, but there’s scant evidence to back it up, he says. He recommends a generally healthy way of eating like the Mediterranean diet, which is rich in fruits and vegetables, fatty fish like salmon, and whole grains, and low in the red meat and processed foods that fuel inflammation. That kind of diet is good for your heart and overall health, “though I can’t guarantee that it will help control your disease or reduce the risk of flares,” he adds.

Exhaustion

It’s hard to sleep when your joints are screaming at you all night. Ironically, some medications that manage arthritis pain have sleeplessness as a side effect, including steroids like prednisone, says the Arthritis Foundation. But you need sleep, and not just to feel rested. While you slumber, your body releases chemicals that help manage your pain. People with RA who don’t sleep well have more severe pain and a lower tolerance for pain than those who get enough rest. Practicing good sleep hygiene, like sticking to a set sleep schedule, can help you get the zzz’s you need.

Flare Warning Signs

How do you know that a flare is incoming? Watch for signs like worsening morning stiffness, joint swelling, and changes in function, suggests Dr. Liebowitz. “You’re having a tough time gripping items or you’re dropping items, or you’re having more trouble turning doorknobs or opening cans and jars,” he says, adding that flare symptoms aren’t always joint related. “Sometimes fatigue, dry eyes or dry mouth, or for some people unintentional weight loss can be signs of a flare.” If you spot symptoms like these, reach out to your rheumatologist for advice, and possibly a medicine adjustment.

What You Can Do About It

Steroids like prednisone are the go-to meds for flares because they work quickly to tame inflammation. Your doctor will keep the dose low and the duration short, because these drugs can cause side effects if you take too much of them and stay on them for too long, our experts say. If your symptoms haven’t improved, a discussion might be in order about whether you need a change in your type or dose of medicine to keep your RA under better control, says Dr. Dave. Your doctor might add another medication to calm your immune system if you find that you’re having lots of flares.
