Connecting Sleep and Immunity

February 03, 2023 2 min read

As we have discussed often, we know that getting adequate rest is essential to our mental and physical health! It’s when the healing and rejuvenation from today’s stresses occur to prepare us to go into battle again tomorrow!

What you may or may not know is how important sleep is in regards to your immune system!

That connection has been well established within the medical and science community.

Research has shown that a lack of sleep can greatly weaken the immune system and leave us much more susceptible to infection and sickness 😷

So how does it work?

During our sleeping hours, our bodies release a protein that helps fight inflammation as well as infection. These proteins are called  cytokines.

Interestingly these same cytokines even help to regulate our sleep patterns and create a feedback loop (a system where output of a system either amplifies or inhibits that system) helping to keep us in homeostasis.

Additionally, likewise with cytokines, sleep affects the production of white blood cells which are one of our main defenses against infection and disease. So the right amount of sleep is crucial for the proper production of these T-cells (not too little, not too much). 

So how much sleep do we need?

7-9 hours is generally the recommendation for homeostatic conditions to be achieved in regards to proper cytokine and T-cell (white blood cells) production to forge a solid immune system. 

So the verdict is in and shows that sleep is a crucial component of overall health and to keeping our immune systems at full go.

Adequate sleep improves immunity. 

Inadequate sleep decreases immunity. 


So make sure to get your daily dose of adequate and restful SLEEP!
