Is sleep an effective immunity booster?


Yes, sleep is an effective immunity booster. Adequate sleep plays a critical role in enhancing immune function by influencing various immunological processes:

  • Antibody Production: Sleep improves immune response to vaccinations. Higher quality sleep before vaccination can lead to higher antibody titers, enhancing the vaccine's effectiveness 1.
  • Natural Killer Cells: Even one night of insufficient sleep can reduce natural killer cell activity by up to 70%, weakening the body's ability to fight off infections and cancers 2.
  • Infection Resistance: Individuals who sleep seven or more hours a night are significantly less likely to develop infections like the common cold after exposure to viruses compared to those who sleep less 3.

    Sleep and Immunity

    Rhonda and Roger discuss the relationship between sleep and the immune system. They delve into the mechanisms involved and how cortisol levels affect the stickiness of immune cells. They also touch on the impact of light exposure on sleep.

  • Cytokine Production: Sleep regulates levels of pro-inflammatory cytokines and other immune responses, helping maintain a balanced immune system and reducing chronic inflammation 4

In addition to enhancing immune cell function and antibody responses, sleep ensures that the immune system's cellular and biochemical processes operate optimally. Chronic sleep deprivation can significantly impair immune function, making it harder for the body to fend off infections and illnesses.
