Multiple Sclerosis and Lifestyle: Supporting Wellbeing Between Relapses

Multiple sclerosis is unpredictable. Between relapses, during remission, or while managing progressive symptoms, you're often left wondering what you can do — beyond your disease-modifying therapy — to support your wellbeing and potentially influence the course of your condition.

The good news is that research increasingly shows lifestyle factors matter in MS. What you eat, how you move, your vitamin D status, how you manage stress, and how well you sleep all influence inflammation, neurodegeneration, and quality of life. These aren't replacements for your neurologist's treatment plan — they're the things you can control that may make a meaningful difference in how you feel between appointments.

This guide covers evidence-based lifestyle strategies that research suggests may support MS management alongside conventional medical care.

Understanding MS: Why Lifestyle Matters Between Relapses

MS involves the immune system attacking myelin — the protective coating around nerve fibres in the brain and spinal cord. This creates areas of inflammation and damage (lesions) that disrupt nerve signalling, causing a wide range of symptoms depending on which nerves are affected.

Disease-modifying therapies (DMTs) target the immune system to reduce relapse frequency and slow progression. But MS pathology involves more than immune attacks — it includes chronic neuroinflammation, oxidative stress, mitochondrial dysfunction, and neurodegeneration that continue even between relapses.

This is where lifestyle strategies become relevant. Research published in Multiple Sclerosis Journal has found that modifiable lifestyle factors are independently associated with disability progression, fatigue severity, and brain volume loss. In other words, what you do between relapses may influence how the disease progresses over time.

Vitamin D: The Strongest Lifestyle Evidence in MS

If there's one lifestyle factor with overwhelming evidence in MS, it's vitamin D. The relationship is remarkable: MS prevalence increases with distance from the equator, and vitamin D deficiency is consistently associated with higher relapse rates, more brain lesions, and faster disability progression.

Large observational studies have found that MS patients with higher vitamin D levels experience fewer relapses and slower progression. The SOLAR trial — a randomised controlled trial — found that high-dose vitamin D supplementation added to interferon-beta therapy tended to reduce disease activity, though the primary endpoint was not statistically significant.

Most MS specialists now recommend maintaining vitamin D levels in the higher range of normal (typically 75-150 nmol/L, though recommendations vary). This usually requires supplementation, especially in less sunny climates. Have your levels tested regularly — your neurologist can advise on the appropriate dose for your situation.

Food sources of vitamin D (fatty fish, egg yolks, fortified foods) contribute but are rarely sufficient alone. Careful sun exposure can help, but needs to be balanced against heat sensitivity, which affects many MS patients.

Exercise: Adapted and Essential

Exercise is one of the most well-studied lifestyle interventions in MS, and the evidence is compelling. Research consistently shows that adapted exercise improves fatigue, walking ability, balance, mood, and cognitive function in MS patients. A Cochrane review confirmed that exercise training improves aerobic capacity, muscle strength, and quality of life without increasing relapse risk.

The key is adaptation — working with your current abilities rather than against your limitations. Effective exercise approaches for MS include:

Working with a physiotherapist experienced in MS can help you develop a safe, effective programme. Start conservatively and progress gradually, paying attention to how your body responds in the hours and days after exercise.

Heat Management: The Uhthoff Phenomenon

Many MS patients experience a temporary worsening of symptoms when their core body temperature rises — a phenomenon known as Uhthoff's phenomenon. This occurs because heat slows nerve conduction in already-damaged nerves. It's not a relapse, but it can be distressing and functionally limiting.

Practical heat management strategies include:

Fatigue Management: The Invisible Symptom

MS fatigue affects up to 90% of patients and is consistently rated as one of the most disabling symptoms. It's distinct from normal tiredness — it's an overwhelming lassitude that can strike unpredictably and doesn't necessarily correlate with physical activity or sleep quality.

MS fatigue has multiple causes: the disease itself (primary fatigue from neurological damage), secondary factors (poor sleep, depression, deconditioning, medication side effects), and the extra energy required for normal activities when the nervous system is compromised.

Management strategies that research supports include:

Anti-Inflammatory Diet: Feeding Your Brain

Diet has become an increasingly studied factor in MS management. While no single diet has been proven to alter the disease course in large-scale trials, several dietary approaches have shown promise in smaller studies and observational research.

The Wahls Protocol, developed by Dr Terry Wahls (who has MS herself), emphasises nutrient-dense foods — particularly colourful vegetables, sulphur-rich vegetables, seaweed, grass-fed meat, and organ meats — while eliminating gluten, dairy, and processed foods. While the protocol hasn't been tested in large randomised trials, pilot studies have shown improvements in fatigue and quality of life.

Broader anti-inflammatory dietary principles supported by MS research include:

Stress Reduction: Protecting Against Relapses

The relationship between stress and MS relapses has been studied extensively. A meta-analysis published in the British Medical Journal found a consistent association between stressful life events and subsequent MS relapses. While not every study agrees on the strength of this association, the overall evidence supports stress management as part of MS care.

The mechanisms likely involve stress-induced immune activation and disruption of the blood-brain barrier — both of which could facilitate the immune attacks that cause relapses. Chronic stress also worsens fatigue, sleep, and mood — all significant quality-of-life factors in MS.

Evidence-based stress management approaches for MS include mindfulness-based interventions (shown in MS-specific trials to reduce stress, fatigue, and depression), progressive muscle relaxation (adapted for any level of physical ability), cognitive behavioural therapy (particularly helpful for adjusting to life with a chronic condition), and nature exposure (even brief time in natural settings measurably reduces stress hormones).

Sleep: Addressing a Hidden Problem

Sleep disorders are significantly more common in MS than in the general population, yet they're frequently underdiagnosed and undertreated. Conditions including restless leg syndrome, sleep apnoea, insomnia, and nocturia (frequent nighttime urination) all occur at elevated rates in MS.

Poor sleep compounds virtually every MS symptom — fatigue worsens, cognition suffers, mood deteriorates, and pain increases. Addressing sleep problems is one of the highest-impact interventions available.

Practical steps include maintaining consistent sleep-wake times, creating a cool and comfortable sleep environment (critical for heat-sensitive patients), discussing specific sleep symptoms with your neurologist (restless legs and sleep apnoea have specific treatments), limiting fluids before bed if nocturia is an issue, and avoiding stimulating activities and screens in the hour before bed.

Cognitive Rehabilitation: Keeping Your Mind Sharp

Cognitive dysfunction affects approximately 50-70% of MS patients. Common difficulties include information processing speed, memory, attention, and executive function. While cognitive changes can be concerning, research shows that cognitive rehabilitation and lifestyle factors can make a meaningful difference.

Strategies supported by research include:

Omega-3 Fatty Acids: Supporting Neurological Health

Omega-3 fatty acids have particular relevance in MS because of their anti-inflammatory properties and their role in myelin structure and repair. DHA, one of the main omega-3 fatty acids found in fish oil, is a major structural component of brain cell membranes.

Research on omega-3 supplementation in MS has shown mixed but generally encouraging results. Some studies have found reduced relapse rates and improved quality of life, while others have shown benefits for inflammatory markers without clear clinical improvements. A study in Prostaglandins, Leukotrienes and Essential Fatty Acids found that omega-3 supplementation reduced inflammatory cytokine production in MS patients.

Good dietary sources include salmon, sardines, mackerel, herring, walnuts, chia seeds, and flaxseeds. If supplementing, aim for products providing at least 1,000 mg combined EPA and DHA daily, and discuss with your neurologist — particularly if you take any blood-thinning medications.

Grounding (Earthing): Neuroinflammation and Nervous System Support

Grounding — direct electrical contact with the earth's surface, either outdoors or through conductive indoor products — is an emerging area of research with potential relevance to MS management, particularly regarding inflammation and autonomic nervous system function.

Chevalier et al. (2012) reviewed the physiological effects of grounding and found evidence of reduced inflammation, improved blood flow, and changes in immune cell activity. For MS patients, where neuroinflammation drives disease progression even between relapses, strategies that may help modulate inflammatory processes are worth considering — though it's important to note that grounding has not been specifically studied in MS populations.

Of particular interest for MS is grounding's potential effect on the autonomic nervous system. Chevalier (2010) found that grounding improved heart rate variability (HRV), indicating enhanced parasympathetic nervous system activity. Autonomic dysfunction is common in MS and contributes to fatigue, temperature regulation problems, bladder issues, and cardiovascular symptoms. Strategies that may support autonomic balance could have broad benefits.

Grounding can be practised simply by walking barefoot on grass, soil, or sand. For consistent indoor grounding, some people use conductive grounding sheets made with stainless steel fibres for overnight use, or grounding mats for daytime use at a desk or on the couch. Premium Grounding is an Australian brand with over 28,000 customers, a 4.82-star rating, a 90-day trial period, and a 3-year warranty.

As with all complementary approaches, grounding should be viewed as one potential piece of a comprehensive management strategy — not a replacement for disease-modifying therapy or neurological care.

Building Your MS Wellness Plan

Living well with MS means taking an active role in the factors within your control. While you can't control when or whether relapses occur, you can influence many of the factors that affect your day-to-day quality of life and may influence long-term outcomes.

A practical approach to building your wellness plan:

Keep your neurologist informed about all lifestyle and supplement strategies you're using. They need a complete picture to provide the best care, and some interactions — however unlikely — are worth monitoring.

MS research is advancing rapidly, and new treatments continue to emerge. In the meantime, the lifestyle strategies in this guide represent things you can do today that may make a genuine difference in how you live with this condition.
