Discover 12 science-backed ways to slow epigenetic aging—from diet and exercise to nature and quality sleep.
Aging isn’t just about wrinkles or gray hair—it’s written deep into our biology. Beneath the surface, tiny molecular changes called epigenetic modifications help determine how quickly our cells and tissues age. These changes don’t alter your DNA sequence, but they do influence which genes switch on or off over time. Which, by the way, can affect everything from energy metabolism and inflammation to brain function and disease risk.
The good news? Epigenetic aging is not fixed. A growing body of research shows that lifestyle, nutrition, stress management, and targeted supplements can slow—and in some cases reverse—biological age. Unlike chronological age, which ticks forward no matter what, biological age reflects how your body is actually functioning. That means the right interventions can help you stay healthier, longer, and biologically younger too.
In this post we’ll explore the top 12 science-backed ways to slow epigenetic aging—from exercise and sleep optimization to polyphenol-rich foods.
12 Ways To Slow Epigenetic Aging
Here’s a list of 12 ways to slow—even reverse—epigenetic aging:
1. Exercise
Structured physical activity—especially combined aerobic and strength training—slows or even reverses epigenetic aging. For instance, one study found that “sedentary middle-aged women reduced their epigenetic age by two years after just eight weeks of combined aerobic and strength training.” The consensus is that maintaining physical fitness is one of “the most effective tools for slowing the body’s internal aging process.”
2. Caloric Restriction (CR)
It wasn’t long ago that longevity expert Dr. David Sinclair said that if he could give a word of advice, it would be to eat less—not more. Reducing caloric intake without malnutrition slows the pace of aging in healthy adults. In a randomized trial a small but sustained reduction in caloric intake yielded measurable slowing in the epigenetic “pace of aging” in participants. Another study claims that “calorie restriction (CR) is currently the most effective non-genetic intervention to delay the aging phenotype.”
3. Go Vegan (Plant-Based)
Switching to a vegan diet for just eight weeks produced measurable anti-aging effects in identical twin participants. In a 2024 randomized controlled trial, one twin in each pair adopted a vegan diet while the other continued their usual omnivorous eating. Researchers tracked changes using multiple epigenetic clocks, which measure biological age across different tissues and systems. The vegan group showed consistent decreases in biological age not only in blood but also across key organ systems—including the heart, liver, endocrine (hormone), and metabolic pathways.
These results suggest that plant-based eating rapidly alters DNA methylation patterns in ways that may slow or even reverse biological aging. The shift likely comes from increased intake of fiber, antioxidants, and polyphenols, combined with reduced consumption of pro-inflammatory animal products, all of which modulate epigenetic regulation.
4. Sleep
Getting enough sleep, maintaining a regular sleep schedule, and ensuring good quality sleep can slow epigenetic aging. One study found that in young adults, shorter and irregular sleep correlated with accelerated epigenetic aging compared to those with longer, more regular sleep. Another report suggests that “worsening sleep quality, especially in poor sleepers, is associated with accelerated epigenetic aging.”
5. Healthy Weight
Keeping a leaner, healthier body fat percentage reduces epigenetic aging. Obesity and high BMI associate with faster epigenetic aging because fat tissue promotes adverse methylation patterns, inflammation, and poorer metabolic gene expression. Although some interventions (diet, exercise) reduce epigenetic age, maintaining lean-mass and avoiding visceral fat accumulation seem particularly protective. One report notes that “Several environmental exposures and lifestyle factors can induce epigenetic aging accelerations, including obesity.”
6. Cold Plunge
You generate epigenetic benefits by exposing your body (or parts of it) to cold. In human brown adipose tissue (BAT), short-term mild cold induces an “epigenomic memory” where gene expression and methylation patterns remain elevated days after exposure. One report notes that “cold exposure has been shown to reduce chronic inflammation, enhance antioxidant defenses, and improve metabolic health by activating brown adipose tissue.”
7. Meditation & Mindfulness
Research shows you can slow epigenetic aging by practicing long-term meditation or regular mindfulness. In a study of long-term meditators, older meditators showed less epigenetic age acceleration compared with age-matched non-meditators. Moreover, years of meditation slowed epigenetic aging in the meditator group.
8. Supplements
Ensuring sufficient intake of nutrients that support methylation, reduce inflammation, and promote cellular repair can slow epigenetic aging. For instance studies show that supplementing with omega-3 fatty acids slows biological aging measured by epigenetic clocks, and the effects increase when combined with vitamin D and exercise.

9. Connect With Nature
You can slow epigenetic aging by regularly earthing, grounding, forest bathing, or spending time in natural environments—whether that means parks, forests, or simply daily exposure to green space. Multiple studies show that green spaces and residential greenery can reduce epigenetic aging and boost methylation in human cells. Exposure to natural light, fresh air, and phytoncides (aromatic compounds from plants) reduce stress hormones, support circadian rhythm, and reduce inflammation. Forest bathing studies further suggest that nature immersion may improve immune cell activity and gene expression related to repair. One study found that “People who lived near more green spaces were biologically 2.5 years younger, on average, than those who live near less greenness.”
10. Methyl-Adaptogens & Polyphenols
Consuming foods like green tea, turmeric, garlic, and berries—compounds known to affect DNA methylation—can lower epigenetic age. In one trial men consuming such methyl adaptogen foods showed reduced epigenetic age markers. Read up on the best methylation foods here.
11. Psychological Well Being
Chronic stress and adverse psychosocial and psychological experiences (e.g. early life stress, etc.,) can accelerate epigenetic aging. Interventions that reduce stress, such as meditation, relaxation, journaling, baths, spiritual practices, social support, etc.—are tied to slower aging. One study found that “negative social experiences accelerate while positive social experiences decelerate epigenetic aging.” Another shows that conscientiousness—e.g., mindfulness—is associated with “slower epigenetic aging, particularly second and third-generation clocks.”
12. Avoiding Toxins & Pollutants
Air pollution, smoking, and endocrine-disrupting chemicals accelerate epigenetic age. Proactively limiting exposure via clean air, filtration, smoking cessation, and cleaner consumer products can protect methylation integrity. One report notes “a robust association between long-term exposure to ambient air pollution with epigenetic age acceleration.”
Takeaway
Epigenetic aging isn’t fixed—you can actively influence it. The strongest evidence points to a lifestyle built on exercise, nutrient-dense foods, supplements, restorative sleep, and stress management. Adding practices like sauna, cold exposure, and red-light therapy engages your body’s repair pathways, while targeted nutrients like omega-3s and vitamin D provide extra support. Crucially, don’t underestimate the power of nature: connecting with green spaces and natural light directly links to slower epigenetic aging and better overall health.
