[Common periodicity of solar atmosphere rotation and function of the human body]

The study is made of the occurrence rates of menstrual cycle periods for approximately 2000 women. Peaks on the distribution histogram, corresponding to 21, 25, 28 and 30 days, coincide with a set of axial rotation periods of the solar atmosphere. It is proposed that the functioning of human organism is determined not only by the Moon but by the rhythmics of solar system.
