Scientists do study cyclic patterns that occur in various aspects of our environment and in our bodies to determine their impact on human health. For example, the possible effects of the moon's phases on human health has been explored for many years.

In that regard, scientists have found NO scientific validity to the claims that biorhythm cyclical patterns influence human health. So keep in mind that the bioryhthm programs presented below are JUST FOR FUN, and you should always attempt to separate fact from folklore when making decisions about your health!
