Sleep & the Immune System: Why It Matters in Inflammation and Autoimmunity
Sleep is not just “down time” – it is an active immune-regulating process that helps keep inflammation in check, supports cellular repair, and stabilises hormonal balance. When sleep is short, fragmented, or out of sync with your circadian rhythm, pro‑inflammatory cytokines rise while regulatory immune pathways that maintain tolerance become less effective. Over time, this low‑grade inflammatory signalling can add to the burden behind chronic inflammatory and autoimmune conditions such as rheumatoid arthritis and multiple sclerosis. The good news is that sleep is modifiable: consistent sleep–wake timing, morning light exposure, treating sleep‑disordered breathing, and evidence‑based insomnia therapies like CBT‑I can all help restore immune resilience and inflammatory balance.
