Adequate sleep enhances host defense by improving infection outcomes and vaccination responses, mediated by the induction of a hormonal constellation that supports immune functions.
Ensure you get adequate sleep, especially around the time of vaccination or when you suspect an infection. Sleep actively boosts your immune response, improving vaccine efficacy and helping your body fight off pathogens more effectively. Prioritizing sleep is a proactive strategy for immune resilience.

Enhancement of sleep during an infection is assumed to feedback to the immune system to promote host defense. Indeed, sleep affects various immune parameters, is associated with a reduced infection risk, and can improve infection outcome and vaccination responses. The induction of a hormonal constellation that supports immune functions is one likely mechanism underlying the immune-supporting effects of sleep.

- Prolonged sleep deficiency (short duration or disturbance) causes chronic, systemic low-grade inflammation, which is associated with increased risk of inflammatory diseases such as diabetes, atherosclerosis, and neurodegeneration.Good
- Immune system activation (e.g., by microbial challenges) triggers an inflammatory response that increases sleep duration and intensity, serving as a homeostatic regulation of slow-wave sleep.Good
