Vous le savez sûrement, avoir un système immunitaire performant est indispensable pour assurer une bonne santé et une bonne qualité de vie. Lorsqu’il est affaibli, les premiers symptômes sont rapidement visibles.
Vulnérable, le corps nous fait ressentir fatigue et lassitude, puis nous tombons facilement malade. En hiver, cela se traduit par un rhume, une angine et autres rhinopharyngites très désagréables au quotidien. Alors comment se protéger ?
Essential oils are a great asset in strengthening your immune system! And they allow you to fight effectively against external aggressions.
The importance of the immune system
We often hear about the importance of preserving and protecting the immune system from many health concerns. But what exactly is the immune system?
These are all defense mechanisms that the body uses to fight external aggressions. Beyond the skin, which constitutes the first immune barrier, multiple cells (in the intestine in particular) are there to destroy foreign bodies that prove to be dangerous for the body.
You may have already heard of lymphocytes? These are the cells in charge of producing antibodies and helping to fight against bacteria and viruses. 
Lorsque les saisons froides approches, il est alors temps de se préparer à affronter les différentes maladies traditionnelles en cette période. Prendre soin de son système immunitaire permet d’éviter des symptômes très désagréables comme :
• La fatigue et le manque d’énergie, qui sont les premiers signes d’un système immunitaire affaibli.
• La vulnérabilité aux bactéries et virus environnants.
• Les infections à répétition.
 
                
Les huiles essentielles sont des alliées dans le renforcement des barrières naturelles du corps.
