The Sleep-Immunity Link: How Rest Fights Off Illness

The Nightly Immune Boost

During deep sleep, your body produces cytokines that target infection – getting less than 6 hours reduces these protective proteins by 50% (Pflügers Archiv).

Vulnerability Timeline

1 night poor sleep: 30% immune dip | 1 week: 2x infection risk | 1 month: 3x illness duration

T-Cell Activation:

Just 3 hours of lost sleep decreases T-cell efficiency by 24%, making vaccines less effective.

Sleep Optimization for Immunity

The 7-Hour Threshold

People sleeping 7+ hours have 4x greater antibody response to vaccines than those getting 6 hours (Sleep Journal).

Temperature Sweet Spot:

Keeping bedroom at 64°F maximizes melatonin production and immune cell activity.

Recovery Sleep Protocol

After poor sleep, adding 90 extra minutes the next night restores 80% of lost immune function.

Supplemental Strategies

Deep Sleep Boosters

Tart cherry juice increases sleep efficiency by 6% while raising antioxidant levels 23%.

Humidity Hack:

40-60% bedroom humidity keeps mucous membranes moist, improving first-line defenses.

Pillow Hygiene:

Washing pillowcases every 3 days reduces allergen exposure that strains immunity.
