The 28-day emotional cycle has a curve similar to that of the physical cycle, with the curve rising in the first half (14 days), or discharge phase, and falling in the second half (also 14 days), or recharge phase. The sample below will help you to fix its main characteristics in mind. Since this cycle probably influences sensitivity and creativity as well as feelings of love and cooperativeness, artists and writers may find their muses visiting them more often and their tempers sweeter in the first two weeks of this cycle. During the first 14 days, one is likely to be cheerier and more optimistic; during the second 14 days a little less open, friendly and hopeful; and on critical days, decidedly grumpy and irritable.
The individual pattern will no doubt vary with individual temperament. Someone with a sunny and very calm disposition may seem a bit cloudy at the low point of the cycle but is unlikely to storm a lot at any time. A more passionate and erratic type can swing through periods of bliss and then astonish us with an outburst of anger three days later. It seems quite likely that some people would experience their biorhythmic fluctuations more strongly than others.
An interesting Condition exists with respect to the 28-day cycle which is not true of the other two. Since 28 days make up four seven-day weeks, the important days of this cycle always fall on the same day of the week, the day of the week on which one was born. A person born on a Monday will know that every other Monday will be a critical day. Whereas "blue Mondays" are traditional, Monday's child will have a critical day one
Monday, a high day the next Monday, another critical, and then a low, and so on throughout the year. This same-day syndrome provides a means of testing the biorhythm theory for yourself. Does experience tell you that your emotionally shaky days are almost always on the same days of the week? It's best to test this out over a period of several months; there are always other elements to account for. Bad news can bring you down even on a high day, but you'll probably be able to handle it better.
