In winter, your metabolism is more vulnerable and more susceptible to infections, resulting in a drop in immunity. Certain lifestyle habits, foods and dietary supplements help strengthen the immune system. To boost your immune system in a natural way and stay in shape in winter, here are our tips.

How do you know if your immune system is weakened?

Are you prone to fatigue? Do you have a cold or are your wounds having trouble healing? You probably have a weakened immune system, also known as immunodeficiency or immunodeficiency.

Tips for boosting the immune system

Taking care of your intestinal flora

Did you know that 70% of your immune system is in the intestine? To optimize your immune system, it is therefore essential to protect and strengthen your intestinal mucous membrane. To do this, you can take a course of probiotics (lactobacillus strains) and favour dairy products, sauerkraut and gherkins.

Managing stress

Poor stress management can adversely affect your health and immune system. Studies have shown that too many stress hormones can weaken the immune system.

The health benefits of sport

One of the most common remedies to manage and relieve stress is regular exercise. Indeed, sport can significantly reduce the risk of respiratory infections. 40 minutes of walking every day can be enough to boost your immune system and relieve tension. However, be careful not to overdo it, as excessive exercise can, on the contrary, weaken your immune system.

Fill up with vitamin D

Vitamin D helps to activate the white blood cells needed to make your antibodies, thus strengthening your immune system. Vitamin D is found in a variety of foods: > Fish (herring, mackerel, sardines, salmon, trout and/or tuna) > the eggs > mushrooms > Dark chocolate (70% cocoa minimum).
