This information is very strange - men have a menstrual cycle
When the full moon is bright in days 13 - 14 - 15 of the lunar month, the human body is filled with fluid and blood seethes. In this case, the person is psychologically volatile.
This was observed in Germany, Britain and America in this period among a lot of people, in bars and places of drinking an increase in their barbarism of behavior.
Police report more problems on these days than any others.
Scientists have been studying the psychological state of some of these people and have shown that people in this period have a higher rate of fluid in their bodies, leading to undesirable behavior!
It is here that we see the wisdom of the (Sunni Muslim custom of) fasting on the "white days" of the 13-15th of every month - because the fasting is congruent with the presence of fluid in the body!
This also reflects the wisdom of cupping on the 17 - 18 - 19 of the month, because in those days the blood has reached a stage Frenzy!
People should think carefully before making any decisions or actions on these days. This is crucial because of their psychological effects on the person - he might regret it later when it is too late!
Glory to God Almighty on the wisdom of creation
Unfortunately, there is no valid scientific proof of people acting differently on different days of the lunar month.
However, I don't know if Muslims were included in these studies, so it is always possible that some groups of people do have a monthly cycle.
It could explain a lot.
