Movement + Immunity

The immune system is the body's defence against foreign invaders that can cause infection. It is a layered mechanism that starts with protective barriers such as the mucous membranes that line our airways, which act as a barrier preventing pathogens from entering our system. 

If this fails, our body engages a vast network of cells, organs, and tissues, that are on the lookout for invaders and once spotted, mounts an immune response.

The lymphatic system plays a crucial role in the immune response, as it circulates leukocytes, AKA white blood cells. There are a number of leukocytes which have different roles, ranging from surrounding, absorbing and breaking down pathogens, to creating a memory of invaders so the body is able to recognize past invaders and attack more efficiently.

Structurally, lymph circulates vessels that do not contain muscles in its walls and is not pressurized by the heart. Therefore, it cannot engage a pumping mechanism to circulate its lymph.

This is unlike the blood vessels of our cardiovascular system, which do contain muscles in its walls and is pressurized by the heart, allowing for active circulation. We can feel this as our pulse.

However, the lymphatic system runs close and parallel to blood vessels. So as blood circulates, lymph does as well, passively by proximity.

So, if the body is stagnant (long flights, desk jobs) or if you have poor circulation, this impacts your immunity by reducing flow of white blood cells to the tissues.

Increasing movement helps boost immunity. On long flights or during your work day, make sure to frequently get up and stretch or go for a walk. Regular exercise will also help to optimize immunity.
