boost your immune system

In the colder months you may be like many people and turn to supplements in order to boost your immune system and protect yourself from getting a cold or the flu. While taking supplements is easy and convenient, you should also know that there are other ways of improving your immune system, without any supplements at all.

If you’d rather not spend any money on expensive supplements, continue reading to see what you can do to boost your immune system naturally.

Boost your immune system naturally

Reduce your sugar intake

If you want to be healthier, reducing your sugar intake is one of the best things you can do for your body. Sugar is well known to suppress your immune system, so you should avoid it as much as you can. This doesn’t mean you should never ever have sugary treats, just don’t have too many and not too often. It will be much better for your health and immune system.

Boost your immune system with exercise

Exercise has many health benefits and that includes a positive effect on your immune system. This is because during the exercise, natural killer cells which are responsible for a strong immune system get stimulated.

After moderate exercise the immune system will often be temporarily enhanced, which will protect you from infections. Be careful, though, as too much exercise can have the opposite effect and can reduce the functioning of the immune system.

Eat a healthy, varied diet

Make sure you eat a healthy, varied diet to get all the vitamins and minerals your body needs. If your life is hectic and don’t always have time to ensure your diet is varied enough, start drinking green smoothies, which will be packed with various vitamins and minerals, essential for a healthy immune system.

Get enough sleep

This is a really important measure you should take in order to keep your immune system working optimally. Get enough sleep! Lack of sleep is associated with all kind of health issues and it also weakens your immune system, making you more susceptible to contracting infections and illnesses. Getting enough sleep strengthens your immune system as it improves the functioning of T cells. These help to kill viruses, bacteria and other pathogens.

Drink more green tea

Green tea is full of antioxidants and comes with many health benefits. Polyphenols  found in green tea boost your natural immunity and also help the body fight infections and even autoimmune diseases. So start drinking green tea regularly to reap all of its benefits. If you are not sure which brand to try first, check out these best green tea brands you can find online.

Use garlic as much as you can

Garlic is a natural antibiotic and a great immune booster. Try and use garlic as much as you can every day. Add freshly crushed garlic to your salads, use it in sauces, soups and roast it together with vegetables in the oven. It’s always better to eat raw garlic but there are still benefits if you consume cooked or roasted.

Eat probiotic-rich foods

Did you know that 70% of the immune system is found in the gut? For this reason you need to make sure you have enough good bacteria in your gut so that your digestive system works optimally. To improve your gut microbiome, consume more foods that contain probiotics, such as sauerkraut, pickles, miso, certain types of yoghurt and kefir.

Make sure you consume enough zinc-rich foods

Zinc is an important mineral to boost your immune system and even a small deficiency can result in an increased susceptibility to infection. To make sure you get enough zinc through your diet, consume the following: freshly popped popcorn, sesame seeds, pumpkin seeds, nuts, oats and if you love seafood, oysters are one of the best sources of zinc you can find. You can also find zinc in eggs, sardines, green peas and whole-wheat bread.

Spice up your food and don’t forget about herbs

Spices are wonderful natural remedies and when you are healthy they help to keep your body in the top condition since they are full of antioxidants and beneficial nutrients. Try to include more immune-boosting spices into your diet such as turmeric, ginger and cinnamon. I add cinnamon every day to my porridge or muesli and use turmeric in various soups, dahl and rice dishes. Ginger is great in seafood dishes and curries but you can also make a ginger tea with it.

Herbs are also beneficial for your immune system, especially oregano, thyme and rosemary. Try and use as many herbs and spices in your cooking as you can.

Are you eating enough omega 3s?

Omega-3 fatty acids are well-known for their anti-inflammatory effect but they also play a role in boosting the immune system as some studies have shown (this study and this study).

Make sure you get your omega-3 dose by eating oily fish at least once a week. Also include plenty of walnuts and avocado in your diet. Flax seeds and chia seeds also contain some omega-3 fatty acids and are easily sprinkled onto cereal or porridge.

Conclusion

So these are some of the things you can do to boost your immune system without resorting to immune support supplements. Of course, it will not be always possible to follow these guidelines but just give it your best try and you will certainly be on your way to making your body more resistant to colds and various infections.

    All good advice. Especially sleep as too little (and too much!) really makes you feel awful.
    It never used to be the case, but getting enough sleep is the bane of my life at the moment. I have a good night time routine and go to bed at a reasonable time, but then lie awake tossing and turning for at least 2 hours! 🙁

      I’m the same. Think it’s a certain time of life, sadly

    I’m extremely fortunate as I have a really good immune system, I very rarely succumb to coughs and colds. It must be hereditary because my daughter is the same. It’s probably a good job that I ‘m naturally healthy as I can’t cope with garlic and my sleep is shocking (at 4 o’clock this morning I was making earrings) and no amount of telling me to get good quality sleep helps nor does anything I have tried.

      It’s a real challenge to sleep well. I don’t tend to get coughs and colds either luckily. I do think a decent diet helps

        Yeah, the menopause and it’s effect on sleep really, really suck. I’m sure there’s a whole generation of women wandering around slightly zombified. It’s not even a well publicised side effect of the menopause.

    I have been sugar free for nearly 25 years and also eat a wholefood diet. I am still chronically ill. I also do most of the other things on the list – except exercise as it makes me a whole lot worse. Before I got ill I used to exercise regularly. I don’t get many colds though – probably because i am ill indoors and don’t come into contact with germs very much.
