Snooze Before a Shot

Have you decided to get your flu shot yet? If you haven’t, you might want to sleep on it—not to help with your decision, but to give your vaccine a better shot.

Researchers studied the effect of sleep loss on vaccinations. They found that people who slept less than six hours on average were over eleven times more likely to be unprotected after a vaccination than those who slept over seven hours. Simply put, people who are sleep-deprived have a lower immune system response to vaccines.

These studies add to a growing bed of evidence that a tired body can lead to a tired immune system, which could increase your risk of flu and other illness.

A flu shot is your best bet to ward off the virus. However, a good night’s sleep before your visit with the vaccine may promote better protection.
