Immune resilience is influenced by many factors, but one of the strongest practical predictors is sleep duration and quality. When sleep is consistently short or fragmented, the body’s immune response can weaken.
Two metrics that matter
- Total sleep time: adults who regularly sleep less may be more susceptible to colds.
- Sleep efficiency: the percentage of time in bed actually spent asleep—low efficiency often signals fragmented sleep.
What to do
- Prioritize a stable bedtime and wake time.
- Reduce evening light exposure and stimulants.
- Address snoring or breathing issues with a clinician.
