Sleep and Your Immune System

Your immune system functions best when your body has had enough sleep.

Sleep provides a regenerating, rebuilding time for your body's systems.

During deep sleep, your cell production increases while protein breakdown rate slows.

In addition, your body releases certain hormones during sleep that scientists think may boost your immune system.

Without enough "down time" to complete its natural restorative and immune-building functions, the body can become vulnerable to infection and disease.

Researchers say that the immune system of a well-rested person is more likely to provide a strong defense against invading bacteria and viruses.
