Now most of you know that I am not a proponent of hepatitis vaccine, but the point of this article really has nothing to do with the vaccine itself. The take-home message is that it appears a well-rested person's immune system may launch a stronger response to an invading virus than that of a sleep-deprived individual.

These findings are quite consistent with previous studies that I have posted on the site. Many do not know that aside from affecting your immune system, not sleeping well or not sleeping enough can increase your risk of diabetes. It will also affect your hormone levels and accelerate aging.

Sleep should be a priority in your life as it plays a dramatic role in your overall health--much like proper nutrition and regular exercise. Without enough sleep, your body will be challenged to reach its optimal state of health.

However, I know that many people find it difficult to sleep and struggle with insomnia nightly. If you have a problem sleeping be sure to read my latest specific guidelines on how to improve your sleep.

Since the study brought up the issue of hepatitis vaccine, I also thought it was important to mention that the hepatitis A vaccine, according to the product insert, has NOT been "evaluated or tested for its carcinogenic potential, mutagenic potential, or for impairment of fertility" or "reproductive capacity." It sure makes sense to give some serious thought to whether the vaccine is worth the risk.
