Right now with everything that is going on in the world it’s more important than ever for those living with thyroid dysfunction to consider effective ways to strengthen the thyroid-immune connection.
The thyroid hormones influence every major system in the body, including the immune health.
The thyroid hormones are constantly communicating with the specialised immune cells to safeguard the body from infections and a host of environmental stressors.
This is the reason why a drop in thyroid hormone activity can weaken the body’s natural defence system.
The good news is, immunity is influenced by multiple factors and there is so much you can do to build immune resilience.
The Important Thyroid-Immune Connection
Over the past few years a lot of research has been done to highlight the important role the thyroid hormones play in maintaining a healthy immune response.
In particular, circulating thyroid hormones help power up various immune cells including monocytes, macrophages, natural killer cells, and lymphocytes. Additionally, the thyroid hormones affect several inflammatory processes such as chemotaxis, phagocytosis, antioxidant defence pathways, and the production of cytokines.
In effect, the thyroid hormones help maintain strong everyday immunity.
Here’s six things you may not already know about immunity and thyroid wellbeing.
SIX Things To Know About Immunity and Daily Wellbeing
1. It’s a Complex, Integrated System
The immune system is a complex system of cells and proteins that defend the body from pathogens. From a science perspective, the most common pathogens includes viruses, bacteria, fungi, parasites and emerging infectious diseases.
2. Innate v. Adaptive Immunity
There are two distinct branches to the immune system; the general innate system and the highly specialized adaptive system.
In an ideal scenario these two systems work in harmony to effectively respond to threats from the environment. While there is still more research to be done it does appear the thyroid hormones support activity of various immune cells, thereby playing a crucial role in both innate and adaptive immunity.
3. Peak Immunity Declines With Ageing
The prevalence of thyroid disorders increases with ageing which is also associated with a decline in peak immune function. When the body is no longer able to mount an appropriate immune response it leads to innate and adaptive immune dysregulation. It explains why older people are more prone to infections and symptoms associated with an infection are often more severe.
4. The Immune System Has a Memory
One of the most significant features of the immune system is the ability to retain a memory of previous infections. The capacity of immune cells to remember and respond to pathogens helps halt reinfection and limits the spread of infection within a local community. Herd immunity occurs is when a significant portion of a population develops immunity to a specific pathogen.
5. Stress And Trauma Wreak Havoc On Immunity
All types of stress impair immunological function. This could be a physical stress to the body, or psychological stress associated with feeling lonely, grief or caregiving. Another consequence of chronic stress is activation of latent viruses. This is topic is covered here on the blog as activation of latent viruses can be the root cause of thyroid fatigue.
6. Micronutrient Deficiencies Matter
It’s worth noting that micronutrient deficiencies are associated with a weakened immune response. Studies show specific nutritional factors play a fundamental role in promoting a balanced immune response. Key micronutrients to maintain immune system health include vitamins A and C, D3, zinc, selenium, iron, B6, B12 and folate.
For many with a diagnosed thyroid disorder this is a challenging time. So, the general advice is to take your thyroid medication as prescribed, take your health supplements regularly, eat well, stay active and choose effective self-care practices to naturally support thyroid wellbeing.
