How to boost your immune system naturally?

Like many of you probably noticed, I was in Finland last weekend celebrating my friend’s wedding. Lovely wedding, lot of friends and laughter, good food and dancing, so kind of perfect quick visit to Finland. I just could not help noticing that the most common topic was autumn and all the runny noses and common colds that it has brought with it.

But hey! There are many ways you can give your immune system a bit of natural boost and avoid all of those nasty colds. Or at least beat most of them by taking care of your body. I listed here my favorite ways to do it:


Choose the right diet.
You can’t never underestimate the importance of good nutrition when we are talking about our immune system, and how to keep it working most efficient way. Incorporating certain foods into your diet could help keep your immune system in tiptop condition. Eat for example plenty of dark leafy greens, vegetables, fruits, oily fish, nuts, and seeds, which will provide your body with the nutrients your immune system needs.

Drink plenty of water. Water helps all of your body’s systems function at optimum levels as it helps to carry oxygen to your body cells. At the same time water clean and remove harmful toxins and so drinking more of it could help prevent toxins from building up and having a negative impact on your immune system.



Get adequate sleep and relax. As simple as it sounds, being stressed out and not having enough sleep could be the key reason why your health is faltering. Both of them increase the production of hormone called cortisol and long-lasting high cortisol levels will reduce your body’s natural immune system. So, tonight when you’re tempted to watch one more episode of your favorite tv-show before going to bed, make an exception and get a decent night’s sleep instead.

Exercise regularly. Exercising and all kind of physical activity (on a moderate physical level) are extremely effective activities to do to prevent a cold, as they may improve your body’s ability to fight infection. Just remember moderation, as crazy over-exercising without recovery days has been associated with an increased probability to catch infections, as well as get injured!

Catch some rays. Briefly explained immune cells are favorably affected by vitamin D levels, and natural sunlight is the best source of natural vitamin D. Deficiency of vitamin D is associated with increased possibility to catch infections, so if you can’t enjoy of the sun every day, it’s highly recommended to take vitamin D supplements. And hey, one more reason to book a vacation in a sunny spot during cold and flu season!



Sweat the germs out in a sauna. You may never have thought, but regular sauna bathing can beneficial to your health. Since many viruses and bacteria can’t survive in high heat, the sauna makes it hard for them to stick around you. It can also help your body tackle a bacterial or viral infection you might be experiencing. Infrated sauna would be the most effective one as it raises your core temperature, helps draw toxins out of the body, lowers blood pressure and reduces stress, but the original version of sauna will do the magic too when used regularly.

These should be obvious, but I’ll put them here just to be sure: smoking and drinking too much alcohol causes a change in the immune system by altering the cells and molecules in the body. This change slows your ability to ward off infections. Also, obesity can cause a state of chronic inflammation, and this causes your immune system to become compromised. And washing hands comes without saying, right!


Have a healthy rest of the year,
