Sleep & Optimally Functioning Immune System
There is clear research-based evidence that getting enough quality sleep is absolutely essential for maintaining optimally functioning immune system. For example, lack of sleep disrupts the production and release of cytokines, which weakens your immune system's ability to defend against foreign invaders. As you might know, cytokines, are a type of proteins that help your immune system to function properly, as they help regulate inflammation, cell signaling, and immune responses.
3 Ways to Promote Optimal Production of Cytokines
Get enough sleep — to allow your body time to produce more cytokines, such as interleukins (IL-1 & IL-6), and tumor necrosis factor-alpha (TNF-α), which are fundamental for strengthening your immune system's ability to keep you safe.
Maintain regular sleep rhythm — the more regular sleep routine you follow, the better your body can produce and release cytokines. Just one poorly slept night is enough to affect the system. The reason is…
