Reducing inflammation in your body comes down to a handful of consistent habits: eating more whole foods, moving regularly, sleeping enough, and managing stress. These aren’t vague wellness tips. Each one targets the specific biological processes that drive chronic inflammation, and the measurable effects are surprisingly large. A Mediterranean-style diet alone can lower key inflammatory markers by 20% or more, and combining endurance exercise with strength training has been shown to cut C-reactive protein levels by 60%.
The strategies below focus on chronic, low-grade inflammation, the kind that builds quietly over months or years and contributes to heart disease, type 2 diabetes, joint problems, and other long-term conditions. This is different from acute inflammation (a sprained ankle, a fever during an infection), which is your immune system doing its job and typically resolves on its own.
How Chronic Inflammation Works
When your body detects an injury or infection, it launches an inflammatory response: immune cells rush to the area, blood flow increases, and signaling molecules called cytokines coordinate the cleanup. In a healthy scenario, this response ramps up, does its work, and shuts off within days. Chronic inflammation is what happens when this process never fully turns off. Your immune system stays partially activated, producing a steady trickle of inflammatory molecules like interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), and C-reactive protein (CRP).
Over time, these molecules damage blood vessels, promote insulin resistance, and contribute to tissue breakdown throughout the body. You typically can’t feel chronic inflammation the way you feel a swollen knee. It shows up indirectly as fatigue, joint stiffness, weight gain, or simply as elevated numbers on a blood test.
Know Your Baseline With a Simple Blood Test
If you want to know whether inflammation is actually a problem for you, the most accessible test is high-sensitivity C-reactive protein (hs-CRP). The American Heart Association and CDC established reference ranges that are still widely used: below 1 mg/L is considered low risk, 1 to 3 mg/L is moderate risk, and 3 mg/L or above signals high inflammatory and cardiovascular risk. This test is inexpensive, widely available, and gives you a concrete number to track as you make changes.
Shift Your Diet Toward Whole Foods
The single most impactful dietary change is moving toward a Mediterranean-style eating pattern: vegetables, fruits, whole grains, legumes, nuts, olive oil, and fish, with less red meat, sugar, and processed food. People with the highest adherence to this pattern show roughly 20% lower CRP levels and 17% lower IL-6 levels compared to those with the lowest adherence. A separate large study of U.S. nurses found even stronger results: 24% lower CRP and 16% lower IL-6.
These aren’t small differences. CRP and IL-6 are two of the most reliable markers of systemic inflammation, and reductions of this size are comparable to what some medications achieve.
Why Ultra-Processed Foods Make Things Worse
Ultra-processed foods don’t just lack nutrients. They actively promote inflammation through at least four mechanisms. Added sugars (especially fructose) and industrial additives like emulsifiers and thickeners damage the protective mucus lining of your gut, allowing bacteria and their byproducts to leak into your bloodstream. They shift the balance of your gut bacteria toward species that trigger immune responses. They reduce production of short-chain fatty acids, which are compounds your gut bacteria normally make to keep inflammation in check. And they directly activate a key inflammatory signaling pathway in your immune cells called NF-κB, which is essentially the master switch for producing inflammatory cytokines.
Common food additives like carrageenan (a thickener found in many dairy alternatives and processed foods) have been shown to activate this same pathway and trigger the release of inflammatory signals in intestinal cells. The practical takeaway: the fewer ingredients on the label that you wouldn’t find in a home kitchen, the better.
Exercise Consistently, and Add Strength Training
Regular exercise is one of the most effective anti-inflammatory interventions available, but the type of exercise matters. In a 15-week study of young women, those who did endurance training alone (running three times per week with a long run on weekends) saw modest improvements. But those who combined running with two weekly strength training sessions experienced a 60% drop in CRP levels, from 2.0 mg/L down to 0.8 mg/L. That’s a shift from moderate inflammatory risk to low risk using the AHA categories.
Interestingly, the group that combined both forms of exercise actually ran 16% fewer miles per week than the endurance-only group. More wasn’t better. The combination was what mattered. Strength training sessions lasted under an hour each, done twice per week on non-consecutive days. This is a realistic schedule for most people.
If you’re starting from a sedentary baseline, any increase in physical activity helps. But if you’re already walking or jogging regularly and want to maximize the anti-inflammatory benefit, adding resistance training is the clearest next step.
Protect Your Sleep
Sleep deprivation is one of the fastest ways to spike inflammatory markers. Research published in JAMA Internal Medicine found that a single night of partial sleep loss (being awake from 11 PM to 3 AM) produced a more than threefold increase in IL-6 gene activity and a twofold increase in TNF-α gene activity the following morning. These aren’t subtle shifts. Your body interprets sleep loss as a threat and responds by ramping up the same inflammatory machinery involved in chronic disease.
This matters because these effects are cumulative. Regularly sleeping fewer than six hours doesn’t just leave you tired. It keeps your immune system in a low-grade state of alert, producing inflammatory molecules around the clock. Prioritizing seven to eight hours of sleep is one of the simplest, most effective anti-inflammatory strategies, yet it’s often the first thing people sacrifice when trying to fit in other health habits like exercise or meal prep.
Manage Chronic Stress
Psychological stress activates your body’s hypothalamic-pituitary-adrenal (HPA) axis, the system that produces cortisol. Short bursts of cortisol are normal and even helpful. But when stress is constant, cortisol levels stay elevated, and your immune cells gradually become less responsive to cortisol’s anti-inflammatory signal. The result is that inflammation rises even as cortisol remains high, a pattern seen in people with chronic work stress, caregiving burden, or untreated anxiety.
The specific stress management technique matters less than consistency. Regular practice of any structured relaxation method (breathing exercises, meditation, yoga, time in nature) has been shown to lower inflammatory markers. The connection between stress and inflammation is bidirectional: inflammation can worsen mood, and poor mood can worsen inflammation. Breaking the cycle at either end helps.
Supplements That Have Evidence Behind Them
Two supplements have the strongest research support for reducing systemic inflammation: omega-3 fatty acids and curcumin.
For omega-3s, the active components are EPA and DHA, found in fish oil and algae-based supplements. Doses of 1 to 3 grams per day of combined EPA and DHA are associated with the most consistent reductions in CRP, TNF-α, and IL-6. Most standard fish oil capsules contain only 300 to 500 mg of combined EPA and DHA per capsule, so check the label carefully. You may need two to four capsules daily to reach the effective range, depending on the product.
Curcumin, the active compound in turmeric, has anti-inflammatory effects at doses of 500 to 1,500 mg per day, but it’s poorly absorbed on its own. Taking it with 5 to 15 mg of piperine (a black pepper extract) significantly improves absorption. Many curcumin supplements now include piperine for this reason. Turmeric in food, while healthy, doesn’t deliver enough curcumin to match the doses used in clinical trials.
Putting It Together
The most effective approach combines several of these strategies rather than relying on any single one. The order of priority, based on the size of measurable effects, looks roughly like this: improve your diet (especially reducing ultra-processed foods), add combined aerobic and strength exercise, fix your sleep, manage stress, and consider targeted supplements. Each layer compounds the benefits of the others. Someone who cleans up their diet but sleeps five hours a night is fighting their own biology. Someone who takes fish oil but lives on processed food is addressing a fraction of the problem.
If you get an hs-CRP test before making changes and again three to six months later, you’ll have a concrete measure of progress. Many people see their levels drop from the high-risk range into the moderate or low-risk range within that timeframe, which reflects a genuine reduction in the biological processes that drive chronic disease.
