Sleep and the Immune System

Lack of sleep makes ours and our children’s immune systems weaker, hence they makes us more prone to catching colds, viral infections and the flu. Our immune system is designed to protect us from colds, flu, and other ailments. Lack of sleep suppresses immune system functions.

A study published in the September 25, 2002 issue of theJournal of the American Medical Associationdemonstrated that a lack of sleep measurably adversely affects the body’s response to the flu vaccine. This study was done in healthy young adults and half of those included in the study slept only 4 hours per night for 6 nights. The comparison group, experienced a normal night’s sleep over the same period of time. Flu vaccines were administered on the 5th day.

Blood test results showed the sleep-deprived group had less than half the antibodies the comparison group did. Once the sleep deprived group resumed normal sleep habits, there was no difference found in levels of immunity between the two groups.

Want to be healthier and make sure your children don’t get as sick? Make sure you all get a good night sleep.
