What are colds and how can we naturally increase immunity to colds?

The common cold is a viral infection that primarily affects the nose and throat. It is a highly contagious illness that is caused by various strains of viruses, most commonly the rhinovirus [I] [ii] [iii].

At some point, we have all experienced the common cold, but some of us seem more prone to picking up a cold than others. What can we do to increase our defences?

Sleep: ensuring we are getting enough sleep will give the body the best chance of being able to fight off infections. Our body’s natural circadian rhythm has an in-built time for optimal immune function. If we interrupt our circadian rhythm, we also interrupt our immune cells operating at their best. Additionally, being ‘under-slept’ means we are more likely to lean on other unhealthy habits like caffeine and sugar fixes which in turn can disrupt the immune system. There are lots of things we can do to support our natural sleep cycle. Reducing exposure to screens 2 hours before bed, getting into the rhythm of a bedtime routine and supplemental support like 5-HTP and magnesium which both play a role in the production of the sleep hormone melatonin [iv].

Tip: Ask one of our qualified in-store nutritional therapists for advice on how supplements can support your sleep.

Stress can cause havoc on our immune systems. If we are operating in our sympathetic nervous system, or ‘fight or flight’ our bodies will prioritise protecting us from the immediate threat that it is detecting. When we live permanently in this state, much of the important maintenance work to keep us healthy is de-prioritised, leaving us vulnerable to catching an infection [v].

Tip: Simple breathing exercises, especially box breathing has been shown to help switch us from the sympathetic nervous system (fight or flight) into rest and digest (parasympathetic)

Nutrients to help fight and prevent colds

Vitamin C: Vitamin C supports both the body’s innate and adaptive immunity through a variety of cellular functions. It is also a powerful antioxidant. High strength vitamin C can be very effective against colds, but there are plenty of everyday foods which are great sources: citrus fruit and their juice, kiwis, green vegetables, peppers, broccoli, red cabbage, strawberries, papaya and mango[vi]. Vitamin C 500mg + Zinc

Tip: Start your day with the juice of 1/2 lemon in water to re-hydrate with a natural dose of vitamin C! (Use a straw to protect your teeth)

Garlic: The active element of garlic known for its immune function is Allicin which is also responsible for the distinctive garlicky smell. Research has shown that daily garlic supplementation can significantly reduce the likelihood of developing a cold. Allicin is also thought to support our gut function via its prebiotic properties and microbiome support. As a large number of our immune cells are in our gut, supporting gut health is a crucial part of overall immune system health[vii]. Allicin Max

Tip: Use a mixture of garlic, onion and ginger as the base for immune boosting sauces.

Beta Glucans: These support the balance of our immune defences by acting as immunomodulators. They work with the immune cells macrophages and natural killer cells. Research has shown them to reduce upper respiratory tract infections like cold and flu in those who are vulnerable. They are gaining popularity as an adjunct therapy to chemotherapy and radiotherapy. Beta glucans are found in the fungal cell wall of mushrooms, especially lesser-known medical grade mushrooms like Reishi, Lion’s Mane, Cordyceps, they can also be found in the prebiotic fibre of oats, barley, seaweed [viii]. PS-7 Mushroom Formula - Organic Powder

Tip: Supermarket oyster and UK forest mushrooms can also be a great source of Beta Glucans to incorporate into your diet. Extra tip: keep your mushrooms out on the counter as they will continue to create vitamin D if exposed to light.

Black Seed: Black or Nigella seed has been used in Asian and Middle Eastern medicine for generations. Studies are now catching up with this ancient wisdom and showing that black seed oil can enhance the action of various white blood cells. Other research suggests that black seed oil can reduce oxidative damage caused by free radicals which can lead to disease[ix]. Black Seed 400mg - Organic

Tip: Nigella seeds are available in most spice aisles, add a teaspoon over roasted veg for a spicy kick

Echinacea: this traditional plant has long been used as a tool to fight infection caused by bacteria and viruses by stimulating the white blood cells. It also has powerful antioxidant properties. There are many forms of echinacea including: tinctures, extracts, capsules and tea[x]. Echinacea Elderberry Extract
