Psoriasis and Inflammation: Managing Flare-Ups from the Inside Out

Understanding Psoriasis: An Inflammatory Autoimmune Condition

Psoriasis affects approximately 2–3% of the world's population — over 125 million people. Far from being simply a skin problem, psoriasis is a chronic autoimmune condition driven by systemic inflammation. The immune system mistakenly accelerates skin cell production, causing cells to build up on the surface in thick, scaly patches that can be painful, itchy, and deeply frustrating to manage.

Because psoriasis is rooted in immune-driven inflammation, researchers and clinicians increasingly recognise that management extends beyond topical treatments applied to the skin's surface. Addressing systemic inflammation through lifestyle, nutrition, stress management, and other supportive approaches may help reduce flare-up frequency and severity when combined with your prescribed treatment plan.

Here are ten evidence-based natural strategies that may help manage psoriasis from the inside out.

1. Consistent Moisturising: Maintaining the Skin Barrier

While moisturising doesn't treat the underlying autoimmune process, maintaining skin hydration is a fundamental part of psoriasis management. Dry skin is more prone to cracking, itching, and the Koebner phenomenon — where psoriasis develops at sites of skin injury or irritation.

Thick, fragrance-free emollients applied immediately after bathing help lock moisture into the skin and soften plaques. Ointment-based moisturisers (petroleum jelly, thick creams) are generally more effective than lotions for psoriasis-prone skin. Look for ingredients like ceramides, shea butter, and glycerin that support barrier function.

Apply moisturiser at least twice daily, and more frequently during flare-ups or in dry, cold weather. Keeping skin well hydrated may also improve the penetration and effectiveness of prescribed topical treatments.

2. Vitamin D and Controlled Sun Exposure

Vitamin D plays a critical role in immune regulation and skin cell growth — both directly relevant to psoriasis. Research has shown that many psoriasis patients have lower vitamin D levels than the general population, and there's a well-documented correlation between winter months (less sun exposure, lower vitamin D) and psoriasis flare-ups.

Controlled sun exposure — 10–15 minutes of direct sunlight on affected areas several times per week — may help slow the rapid skin cell turnover that characterises psoriasis. UV light therapy (phototherapy) remains one of the most effective treatments for moderate to severe psoriasis, and natural sunlight provides a similar mechanism on a smaller scale.

Vitamin D supplementation may also be beneficial, particularly during winter months or for those with limited sun exposure. Studies published in Dermatology and Therapy suggest that oral vitamin D supplementation may help improve psoriasis severity scores. Discuss appropriate dosing with your healthcare provider, as vitamin D has an upper intake limit.

3. Omega-3 Fatty Acids: Modulating the Inflammatory Response

Omega-3 fatty acids — found abundantly in oily fish, flaxseed, and walnuts — are potent modulators of inflammatory pathways. They compete with pro-inflammatory omega-6 fatty acids for incorporation into cell membranes and help produce anti-inflammatory molecules called resolvins and protectins.

A systematic review in the Journal of the American Academy of Dermatology found that omega-3 supplementation (typically 2–4 grams of EPA and DHA daily) was associated with improvements in psoriasis severity in several clinical trials, though results varied between studies. The anti-inflammatory effects appear to be most pronounced when omega-3 supplementation is combined with an overall reduction in omega-6 intake.

Aim for two to three servings of oily fish per week (salmon, mackerel, sardines) and consider a high-quality fish oil supplement. Plant-based omega-3 sources like flaxseed and chia seeds provide ALA, which the body converts to EPA and DHA at lower rates but still contributes to the overall anti-inflammatory balance.

4. Anti-Inflammatory Diet: Reducing Internal Fire

Because psoriasis is driven by systemic inflammation, dietary patterns that reduce overall inflammatory load may help support management. The Mediterranean diet — rich in fruits, vegetables, olive oil, fish, nuts, and whole grains — has been associated with lower psoriasis severity in observational studies. To learn more, explore our article on grounding sheets for pain and inflammation.

A 2018 study in JAMA Dermatology found that psoriasis patients who followed a Mediterranean-style dietary pattern had lower disease severity compared to those with less anti-inflammatory diets. Specific foods associated with anti-inflammatory effects include colourful fruits and vegetables (rich in polyphenols and antioxidants), extra-virgin olive oil, fatty fish, nuts, and fermented foods.

Conversely, certain dietary patterns may promote inflammation and worsen psoriasis. Excessive alcohol consumption, ultra-processed foods, high-sugar diets, and excessive red meat have all been associated with increased psoriasis severity in research.

5. Stress Management: Breaking the Flare-Up Cycle

Stress is one of the most commonly reported psoriasis triggers, with up to 80% of patients identifying stress as a factor in their flare-ups. The mechanism is well understood: psychological stress activates the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system, releasing cortisol and pro-inflammatory cytokines that can directly stimulate the immune pathways involved in psoriasis.

This creates a vicious cycle — stress triggers flare-ups, and visible skin lesions create self-consciousness, social anxiety, and more stress. Breaking this cycle requires active, consistent stress management rather than waiting until stress becomes overwhelming.

Evidence-based approaches include mindfulness meditation, which has been shown to enhance the effectiveness of phototherapy for psoriasis in a landmark study by Kabat-Zinn et al. Other effective techniques include progressive muscle relaxation, yoga, regular exercise, adequate sleep, and cognitive behavioural therapy. Even 10–15 minutes of daily meditation or deep breathing practice may help modulate the stress-inflammation pathway.

6. Sleep Quality: Immune Regulation Overnight

Sleep and immune function are intimately connected. During deep sleep, the immune system undergoes crucial regulatory processes — and disrupted sleep has been shown to shift the immune balance toward a pro-inflammatory state. Research published in Sleep Medicine Reviews found that psoriasis patients have significantly higher rates of sleep disturbance than the general population, creating a self-reinforcing cycle of poor sleep and immune dysregulation.

Prioritising sleep hygiene may help support immune balance. This means maintaining a consistent sleep schedule, keeping your bedroom cool (around 18°C / 65°F) and dark, avoiding screens for at least 30 minutes before bed, and managing nighttime itching through moisturising and appropriate bedding choices. Natural-fibre sheets in breathable materials may help regulate temperature and reduce skin irritation during sleep. For more strategies, explore our complete guide to sleep optimisation.

7. Weight Management: Reducing Inflammatory Load

Obesity and psoriasis have a well-documented bidirectional relationship. Excess body fat — particularly visceral fat — produces inflammatory cytokines (including TNF-alpha and IL-6) that directly contribute to the inflammatory cascade driving psoriasis. At the same time, psoriasis-related inflammation may contribute to metabolic changes that promote weight gain.

Research published in the British Journal of Dermatology has shown that even modest weight loss (5–10% of body weight) can significantly improve psoriasis severity. A large randomised controlled trial found that a low-calorie diet leading to weight loss resulted in meaningful PASI (Psoriasis Area and Severity Index) score improvements compared to a regular diet.

The most sustainable approach focuses on gradual, long-term changes rather than crash dieting. Combining anti-inflammatory dietary patterns with regular physical activity supports both weight management and inflammation reduction simultaneously.

8. Probiotics: The Gut-Skin Connection

The gut-skin axis — the communication pathway between gut microbiome health and skin inflammation — is an active area of psoriasis research. Studies have found that psoriasis patients often have altered gut microbiome composition, with reduced microbial diversity and different bacterial populations compared to healthy individuals.

Preliminary research suggests that certain probiotic strains may help modulate the immune responses involved in psoriasis. A pilot study published in Gut Microbes found that a multi-strain probiotic supplement improved psoriasis severity scores over 12 weeks. Other research has linked specific Lactobacillus and Bifidobacterium strains to reduced levels of inflammatory markers relevant to psoriasis.

While the evidence is still emerging, supporting gut health through probiotic-rich fermented foods (yoghurt, kefir, sauerkraut, kimchi) and prebiotic fibre may contribute to a healthier immune balance. Discuss targeted probiotic supplementation with your healthcare provider.

9. Turmeric (Curcumin): Natural Anti-Inflammatory Compound

Curcumin, the active compound in turmeric, is one of the most studied natural anti-inflammatory substances. It works by inhibiting multiple inflammatory pathways, including NF-kB — a key transcription factor involved in the inflammatory cascade that drives psoriasis.

A systematic review in Phytotherapy Research found that curcumin demonstrated anti-psoriatic effects in both topical and oral forms across multiple studies. Oral curcumin supplementation has been shown to reduce levels of inflammatory markers including TNF-alpha and IL-17 — both central to psoriasis pathophysiology.

Standard curcumin is poorly absorbed, so look for formulations with enhanced bioavailability (containing piperine, liposomal, or phytosome forms). Typical studied doses range from 500mg to 2,000mg of curcumin daily. Turmeric is generally well tolerated but may interact with blood thinners and certain medications — consult your healthcare provider before supplementing.

10. Grounding (Earthing): Exploring Autoimmune Inflammation Support

Grounding, or earthing, involves direct physical contact with the Earth's surface — through barefoot outdoor contact or conductive indoor products. As a practice targeting systemic inflammation, it may have theoretical relevance to autoimmune inflammatory conditions like psoriasis, though specific research on psoriasis has not yet been conducted.

Brown, Chevalier, and Hill (2010) proposed a hypothesis in the Journal of Alternative and Complementary Medicine that grounding may influence immune function by providing free electrons that help modulate inflammatory processes. Their review suggested that the Earth's surface electrons could act as natural antioxidants, potentially reducing the chronic oxidative stress that contributes to autoimmune inflammation.

Chevalier et al. (2012) further documented in the Journal of Environmental and Public Health that grounding appeared to reduce markers associated with chronic inflammation, including changes in white blood cell counts, cytokine concentrations, and other immune-related parameters. These are the same types of immune markers that are elevated in psoriasis and contribute to the accelerated skin cell production that characterises the condition.

While these findings are promising, it's essential to understand that grounding has not been specifically tested for psoriasis. The research base is still small, and more rigorous studies are needed before definitive conclusions can be drawn. That said, as a low-risk approach that may help support overall inflammatory balance and sleep quality, some people choose to explore grounding alongside their existing psoriasis treatment. Options include spending time barefoot outdoors or using products like grounding sheets or grounding mats.

A Comprehensive Approach to Psoriasis Management

Managing psoriasis effectively means addressing the condition from multiple angles. The most successful approaches combine prescribed medical treatments with lifestyle modifications that target the underlying systemic inflammation. No single natural strategy will replace medical treatment, but collectively, these approaches may help reduce flare-up frequency, improve quality of life, and support the effectiveness of your prescribed therapies.

Work closely with your dermatologist to develop an integrated management plan. Track your flare-ups, triggers, and responses to different approaches so you can continuously refine your strategy. Understanding the broader role of chronic inflammation in your health may also provide valuable context for your psoriasis management journey. Be patient and persistent — meaningful improvements often develop gradually over weeks and months.
