How to Boost Your Immune System: Practical Ways to Support Your Health
Updated: Sep 11
Your immune system works quietly in the background every day, helping to protect your body against infections and illness.
It's understandable, then, that so many people search for ways to "boost" their immune system — particularly during the winter months or at times when they feel run down.
But there isn't a single food, vitamin, supplement or technique that can suddenly supercharge your immunity. A better way to think about it is supporting your immune system by looking after your health as a whole.
That includes eating well, sleeping adequately, staying active, managing stress and avoiding habits that can undermine your general health. NHS healthy-living guidance similarly focuses on these broader lifestyle factors rather than a quick immune-system fix.
I'm Sharon Shinwell, a UK clinical hypnotherapist, counsellor and psychotherapist with more than 25 years' professional experience. In my work, I've seen how easily looking after ourselves can slip down the priority list when we're stressed, overtired or overwhelmed.
I've also created a Boost Your Immune System Guided Meditation & Visualisation for people who want to combine relaxation with positive imagery focused on their body's natural defence and healing processes. It isn't intended to prevent or treat illness, but it can provide a calming way to relax and focus on supporting your overall wellbeing.
Can You Really Boost Your Immune System?
The phrase "boost your immune system" is appealing, but immunity is far more complicated than simply turning it up.
Your immune system is a complex network of cells, tissues and organs that work together. What you really want is an immune system that functions appropriately, rather than one that is indiscriminately more active.
That's why I would be wary of products or supplements promising to "boost immunity" quickly.
There are, however, sensible things you can do to support your general health and give your body what it needs to function normally.
1. Eat a Varied and Balanced Diet
Your body needs a range of nutrients to function properly, and your immune system is no exception.
Rather than concentrating on supposed "immune-boosting" superfoods, aim for variety and balance across your diet.
Fruit and vegetables, higher-fibre starchy foods, protein sources and dairy or suitable alternatives can all form part of a balanced diet.
The NHS advises that most people should be able to obtain the vitamins and minerals they need by eating a varied and balanced diet.
That may be less exciting than the latest miracle food, but your immune system doesn't depend upon one special ingredient.
2. Get Enough Sleep
Sleep is one of the foundations of good physical and mental health.
When you're sleeping badly, you may also find it harder to look after yourself in other ways. You may have less energy to exercise, rely more heavily on convenience foods and find everyday stress more difficult to manage.
Rather than viewing extra sleep as something that will continually "boost" immunity, concentrate on getting the sleep your body needs.
Try to keep reasonably regular sleep and waking times, give yourself time to wind down before bed and address persistent sleep difficulties rather than simply accepting exhaustion as normal.
If you're regularly struggling to sleep, it is worth considering what may be contributing to the problem.
3. Stay Physically Active
Regular physical activity has benefits throughout the body.
The NHS recommends that adults aim to be physically active every day and achieve at least 150 minutes of activity each week. Regular activity is associated with numerous physical and mental health benefits, including improved mood, sleep and energy.
You don't necessarily need a complicated exercise programme.
Walking, cycling, swimming, gardening, dancing and many other activities can all help you become more active.
The most useful exercise is often the kind you can realistically continue doing.
4. Manage Ongoing Stress
Stress is a normal part of life, and a short period of stress doesn't mean that your immune system has suddenly stopped working.
But persistent stress can affect your wellbeing in many ways.
You may sleep badly, eat differently, exercise less, drink more alcohol or simply feel physically and mentally exhausted. The NHS notes that stress can affect sleep, eating, drinking, smoking and other behaviours as well as producing a range of physical and psychological symptoms.
So rather than becoming anxious about whether stress is "damaging your immunity", concentrate on reducing unnecessary stress for the wider benefits to your health.
That might mean making more time for relaxation, addressing a source of pressure where possible, exercising, using breathing techniques, talking to somebody or simply creating periods in your day when you aren't constantly doing something.
5. Be Sensible About Alcohol
Alcohol can easily become part of the way we relax, particularly after a stressful day.
But drinking regularly above recommended levels carries significant health risks.
UK guidance advises men and women who drink regularly not to exceed 14 units a week, spreading this across three or more days if drinking as much as 14 units.
You don't need to think about alcohol solely in terms of immunity. Drinking less, particularly if you regularly exceed recommended levels, can benefit your health more broadly.
If cutting down feels more difficult than you'd expected, I've also created an Alcohol Control Self-Hypnosis MP3 to help you work on the habits, triggers and automatic patterns that can make it difficult to reduce your drinking.
6. Don't Smoke
If you smoke, stopping is one of the most significant things you can do for your health.
It's easy to become distracted by relatively minor lifestyle changes while overlooking something with a much greater impact.
If stopping feels difficult, you don't have to rely entirely on willpower. NHS stop-smoking services and treatments can provide support.
I also have professional experience in this area, having previously worked as an NHS Smoking Cessation Advisor, as well as helping people to stop smoking through hypnotherapy.
If you'd like additional help with the habitual and psychological side of smoking, I've created a Stop Smoking Self-Hypnosis MP3 to help you change the thoughts, associations and automatic habits that can make cigarettes difficult to leave behind.
7. Don't Assume More Vitamins Mean More Protection
Supplements are heavily marketed for "immune support", particularly during winter.
But more isn't necessarily better.
Most people should obtain the nutrients they need through a varied and balanced diet, although there are circumstances where particular supplements are recommended.
One important UK example is vitamin D. The NHS advises adults and children over four to consider taking 10 micrograms of vitamin D daily during autumn and winter, when sunlight in the UK isn't strong enough for most people to make sufficient vitamin D through their skin.
If you have a diagnosed deficiency, medical condition, take medication or aren't sure whether you need a supplement, speak to an appropriate healthcare professional rather than taking high doses yourself.
8. Keep Recommended Vaccinations Up to Date
Healthy habits are valuable, but they shouldn't be treated as alternatives to established ways of preventing infectious disease.
Vaccination trains the immune system to recognise and protect against particular infections, and the NHS describes vaccines as the most effective way of preventing many infectious diseases.
Which vaccinations are appropriate depends on factors such as your age, health, occupation, pregnancy and travel, so follow current NHS guidance or speak to your GP surgery or pharmacist if you're unsure.
What About Meditation and the Immune System?
This is an area where it's particularly important not to overstate what meditation can do.
I wouldn't tell somebody that meditation can prevent an infection or treat an illness, and it shouldn't be used instead of appropriate medical care.
Where meditation can be useful is relaxation and stress management.
Taking some time to slow down, breathe more comfortably and shift your attention away from constant worry can be a useful part of looking after your mental and physical wellbeing.
That's the purpose behind my Boost Your Immune System Guided Meditation & Visualisation.
The session uses relaxation and guided imagery centred around the body's natural protective processes. I see it as a wellbeing and relaxation exercise rather than a medical treatment or a way of guaranteeing stronger immunity.
Be Wary of Immune-Boosting Claims
Whenever there's widespread concern about illness, products promising to strengthen or boost immunity tend to appear.
It's sensible to be sceptical of dramatic claims.
A supplement, detox, drink or particular food isn't a substitute for looking after your health more broadly, and "natural" doesn't automatically mean effective or risk-free.
Be particularly cautious if something claims to prevent or cure an illness by boosting your immune system.
Reliable health information from organisations such as the NHS is a much better starting point than health claims made primarily to sell a product.
When to Speak to Your Doctor
If you're concerned that you may have a weakened immune system, are experiencing repeated or unusual infections, or have symptoms that concern you, speak to your GP rather than trying to diagnose or "boost" your immune system yourself.
Some medical conditions and treatments can affect immunity and need appropriate professional advice.
Similarly, if you've been told that you are immunocompromised, follow the advice of your healthcare team about vaccinations, infection prevention and any other precautions that are appropriate for you.
Frequently Asked Questions
How can I boost my immune system naturally?
Rather than looking for a single way to boost immunity, concentrate on supporting your general health through a balanced diet, sufficient sleep, regular physical activity, stress management, not smoking and sensible alcohol consumption. Follow NHS advice on supplements and vaccinations where applicable.
What foods boost the immune system?
There isn't one particular food that can suddenly boost your immune system. Eating a varied and balanced diet helps provide the nutrients your body needs to function normally.
What vitamins help your immune system?
A range of vitamins and minerals are involved in normal bodily functions, including immune function, but that doesn't mean taking large doses will make your immune system stronger. Most people should obtain their nutrients from a balanced diet, with supplements used where recommended or medically appropriate.
Does vitamin D boost your immune system?
Vitamin D has important functions in the body, but taking more than you need shouldn't be viewed as a way of continually boosting immunity. In the UK, the NHS recommends considering a daily 10-microgram vitamin D supplement during autumn and winter.
Can meditation boost your immune system?
I wouldn't claim that meditation directly boosts your immune system or protects you from infection. Meditation can, however, be useful for relaxation and managing stress, which can form part of a healthier overall lifestyle.
Supporting Your Immune System Means Supporting Your Health
There isn't a magic switch for immunity.
Your immune system is part of your body, so many of the familiar things that support general health matter here too: eating well, sleeping adequately, being active, managing stress, avoiding smoking, keeping alcohol within recommended limits and following appropriate medical and vaccination advice.
None of those sounds quite as exciting as a miracle immune booster.
But they're far more useful foundations on which to build.
And if relaxation is one of the areas you've been neglecting, setting aside a little time to slow down and look after your wellbeing can be a worthwhile place to start.
