Ravi Mehrotra։ How Sleep Boosts Your Immune System

Ravi Mehrotra, Chief Medical Officer at Open Health Systems Laboratory (OHSL), shared a post on LinkedIn his own post, adding:

“Part III. How Sleep Boosts Your Immune System

The immune system and sleep have a powerful, two-way relationship, and this is especially critical for cancer patients. When you sleep, your body isn’t just resting; it’s actively producing and releasing essential immune system components like,

Production of Cytokines: Cytokines are a type of protein that play a major role in fighting infection and inflammation.3 When you’re sick or under stress (like during cancer therapy), your body needs more cytokines. Deep sleep is when your body increases the production of these crucial proteins.

Strengthening T-cells: Research has shown that sleep enhances the function of T-cells, which are a type of immune cell that recognizes and destroys foreign invaders, including viruses and cancer cells.5 A lack of sleep can make T-cells less effective.

Reduced Inflammation: Chronic inflammation is often associated with a weakened immune response and can be a side effect of cancer treatment.6 Sleep helps regulate your body’s inflammatory response, which in turn supports immune function.

For patient with cancer, who often has a compromised immune system due to chemotherapy or radiation, sufficient sleep is a free, vital, non-pharmacological way to help their body defend itself against infections and support its ability to fight the disease.”
