Lowering inflammation in your body comes down to a handful of consistent habits: improving your diet, moving regularly, sleeping enough, managing stress, and cutting back on things that trigger inflammatory responses. None of these work overnight, but the evidence behind each one is strong, and most people see measurable changes in inflammatory markers within weeks to months of making real shifts.
Inflammation itself isn’t always bad. It’s your immune system’s response to injury or infection. The problem is when that response stays switched on with no clear threat, a state called chronic or systemic inflammation. This kind of low-grade, persistent inflammation contributes to heart disease, type 2 diabetes, certain cancers, and joint disorders. The good news is that lifestyle changes can meaningfully dial it down.
How to Know If You Have It
Chronic inflammation doesn’t always announce itself with obvious symptoms. Fatigue, joint stiffness, brain fog, digestive issues, and frequent infections can all be signs, but they overlap with dozens of other conditions. The most reliable way to measure systemic inflammation is through a blood test for C-reactive protein (CRP), a molecule your liver produces in response to inflammation throughout the body.
A standard CRP test flags results at or above 8 to 10 mg/L as high. For cardiovascular risk specifically, a high-sensitivity version of the test (hs-CRP) uses a finer scale: below 2.0 mg/L suggests lower risk, while 2.0 mg/L or above signals higher risk. If you’re trying to track whether your lifestyle changes are working, asking your doctor for an hs-CRP test at baseline and again a few months later gives you a concrete number to compare.
Eat More Plants, Less Processed Food
Diet is the single most powerful lever you have. A Mediterranean-style eating pattern, built around vegetables, fruits, whole grains, legumes, nuts, olive oil, and fish, consistently lowers inflammatory markers in clinical research. The pattern works not because of any single food but because of what it adds (fiber, polyphenols, omega-3 fats) and what it displaces (refined sugar, processed meat, seed oils high in omega-6 fatty acids).
Fiber deserves special attention. Your gut bacteria ferment dietary fiber into short-chain fatty acids, which help maintain the intestinal lining. When that lining becomes too permeable, bacterial fragments called lipopolysaccharides (LPS) can cross into your bloodstream and trigger immune activation. LPS molecules are large enough that they normally can’t slip between cells easily. They have to be actively transported through the gut wall, a process that ramps up when the barrier is compromised by a low-fiber, high-sugar diet. Eating a variety of fiber sources (oats, lentils, beans, vegetables, whole fruit) helps keep that barrier intact.
Foods with the strongest anti-inflammatory reputations include fatty fish like salmon and sardines, leafy greens, berries, tomatoes, nuts (especially walnuts), and extra-virgin olive oil. On the other side, the most consistently pro-inflammatory foods are sugar-sweetened beverages, refined carbohydrates, fried foods, and processed red meat.
Exercise Consistently, Not Excessively
Regular physical activity is one of the most reliable ways to lower baseline inflammation. During exercise, your muscles release signaling molecules that have anti-inflammatory effects throughout the body. Both moderate steady-state cardio and higher-intensity interval training trigger this response, though the timing differs slightly. In research comparing five weeks of interval training to moderate continuous running (three sessions per week), both formats raised anti-inflammatory signaling molecules after each session. Over time, the body’s inflammatory response to exercise actually becomes smaller, a sign that your system is adapting and becoming less reactive overall.
The practical target is about 150 minutes per week of moderate activity, or 75 minutes of vigorous activity, spread across most days. Walking counts. So does cycling, swimming, dancing, or strength training. The key is consistency over intensity. Overdoing it, especially with sudden spikes in training volume, can temporarily increase inflammation rather than reduce it.
Sleep at Least Seven Hours
Short sleep is one of the fastest ways to raise inflammation. In a controlled experiment at the University of Pennsylvania, subjects who slept only 4.2 hours per night for 10 consecutive days saw their CRP levels jump roughly fivefold compared to baseline. That’s a dramatic increase from a relatively modest sleep cut. In a separate arm of the same research, people kept awake for 88 continuous hours showed steadily climbing CRP levels that remained elevated even after a recovery night of sleep.
The threshold appears to sit around seven hours. Consistently sleeping less than that is associated with higher levels of multiple inflammatory markers, including CRP and IL-6. If you’re doing everything else right but sleeping six hours a night, you’re likely undermining your progress. Prioritizing sleep hygiene (consistent bedtime, cool room, limited screens before bed) is not a soft recommendation. It’s one of the most measurable interventions you can make.
Manage Stress Through Your Nervous System
Chronic psychological stress keeps your body in a state of immune readiness, which means elevated inflammatory signaling. The mechanism connecting your brain to your immune system runs largely through the vagus nerve, the long nerve connecting your brainstem to your heart, lungs, and gut. When the vagus nerve is activated, it sends signals that suppress the production of key inflammatory molecules, including TNF, IL-6, and IL-1β. It does this by ultimately telling immune cells in the spleen to dial down their activity.
Anything that stimulates vagal tone helps engage this pathway. Deep, slow breathing (especially with a longer exhale than inhale), meditation, yoga, cold water exposure, and even humming or singing all activate vagus nerve signaling. You don’t need to do all of these. Pick one that fits your life and practice it regularly. The anti-inflammatory effects of stress reduction are real, measurable, and separate from the benefits of diet and exercise.
Watch Your Alcohol Intake
Alcohol and inflammation have a J-shaped relationship. In a study published in Circulation that measured inflammatory markers in older adults, people who consumed one to seven drinks per week had the lowest levels of both CRP and IL-6. About 15% of moderate drinkers had elevated levels of both markers. That number rose to 20% among people who never drank, and jumped to 27-28% among those having eight or more drinks per week.
The takeaway is not that everyone should drink. It’s that heavy drinking (more than seven drinks per week) is clearly pro-inflammatory, while moderate intake appears neutral or slightly favorable in this population. If you currently drink more than that, cutting back is one of the simpler changes you can make.
Supplements That May Help
Two supplements have the most evidence behind them for inflammation: omega-3 fatty acids and curcumin.
Omega-3s from fish oil (specifically EPA and DHA) reduce inflammatory signaling throughout the body. The FDA recommends that supplement labels not exceed 2 grams of combined EPA and DHA per day. The NIH notes that very high doses, around 900 mg of EPA plus 600 mg of DHA or more for several weeks, may actually suppress immune function too much. For most people, a combined dose of 1 to 2 grams daily from a quality fish oil is a reasonable range.
Curcumin, the active compound in turmeric, has shown anti-inflammatory effects in multiple clinical trials. Doses in studies range widely, from 500 mg to 6 grams per day depending on the condition being treated. In one trial, 500 mg per day of curcumin reduced joint tenderness and swelling in rheumatoid arthritis patients as effectively as a standard anti-inflammatory drug. The catch is that curcumin is poorly absorbed on its own. Formulations that include piperine (a black pepper extract) significantly improve absorption. Researchers at Oregon State University note it’s unclear whether doses below 3.6 grams per day are biologically active without an absorption enhancer, so choosing a bioavailability-enhanced product matters.
What a Realistic Plan Looks Like
You don’t need to overhaul your entire life at once. The people who successfully lower their inflammation tend to layer changes gradually. A reasonable starting point: shift your diet toward more vegetables, fruit, and fish while cutting back on processed food and sugar. Add 30 minutes of moderate movement on most days. Protect seven-plus hours of sleep. Practice some form of daily stress management, even five minutes of slow breathing. Limit alcohol to seven or fewer drinks per week.
These changes compound. Inflammation is not something you fix once. It’s something you manage through the daily inputs your body receives: what you eat, how you move, how you sleep, and how you handle stress. The markers respond. Give it eight to twelve weeks of consistent effort, and a repeat CRP test will typically reflect the difference.
